Description

  The present disclosure relates to a technique for cutting hair and a wrinkle used for cutting hair.

  In cutting hair, the amount of hair may be adjusted using a plow or the like in order to adjust the hairstyle. However, when the hair quality is curly hair, etc., as a result of adjusting the amount of hair using a plow or the like, the amount of hair jumping or undulation may become severe, and the appearance may deteriorate.

  On the other hand, Patent Document 1 describes a haircut method for adjusting the amount of hair without using a plow. In the hair cutting method, a bundle of hairs that can be cut at a time is taken out from an elongated region extending vertically in the scalp. Then, the hair bundle is cut with an inclination so that the hair becomes shorter toward the upper side of the hair bundle.

Japanese Patent No. 5191614

However, when the hair cutting method of Patent Document 1 is applied to curly hair, the hair ends bounce outward, and as a result, the appearance may deteriorate.
The present disclosure aims to improve the appearance of hair.

  A hair cutting method according to one aspect of the present disclosure is a method of cutting a recipient's hair, and includes an extraction step, a support step, and a cutting step. The extraction step determines the direction of hair flow, which is the direction in which the hair to be cut extends, and is located at the root of the hair in the scalp of the recipient and from the elongated region extending along the direction of hair flow. This is a step of taking out a hair bundle which is a bundle of hair. Further, the supporting step is a step of supporting the taken out hair bundle at a support position, and spreading the hair bundle in a strip shape and extending in the extending direction from the support position toward the root of the hair bundle. . The cutting step is a step of cutting the supported hair bundle along an inclined cut line that is inclined with respect to the extending direction. And the edge part located in the opposite side of a hair flow direction among the edge parts of the width direction in the supported hair | bristle bundle is made into a longitudinal side. The inclined cut line is a line that inclines away from the scalp as it goes to the longitudinal side.

  According to such a configuration, each hair bundle taken out in the take-out step has a shorter hair length on the hair flow direction side than the hair on the opposite side of the hair flow direction. As a result, the hair bundle extends in the flow direction while curving in a C shape on the scalp side. For this reason, for example, when the hair quality of the hair is curly hair, it is possible to suppress the hair from swelling in an S shape or jumping outward. Therefore, the appearance of the hair can be improved.

In addition, the inclination cut line may become less inclined with respect to the extension direction toward the longitudinal side.
According to such a configuration, each hair bundle taken out in the take-out step can be appropriately curved in a C shape. Therefore, the appearance of the hair can be improved.

  Moreover, it is good also considering the edge part located in the opposite side of a long side among the edge parts of the width direction in the supported hair | bristle bundle as a short side. In the cutting step, the supported hair bundle may be further cut along a step cut line extending from the short side of the hair bundle to one end of the inclined cut line. Further, the step cut line may be orthogonal to the extension direction, or may be inclined with respect to the extension direction so as to approach the scalp toward the longitudinal side.

  According to such a configuration, a portion cut along the inclined cut line (hereinafter referred to as an inclined portion) in each hair bundle taken out in the take-out step is the other hair bundle adjacent to the hair flow direction. It will be in the state which had the space | interval between the inclination parts. For this reason, it can suppress that the inclined part in each hair | bristle bundle is entangled, and the touch and finger passage of hair become favorable.

  Further, in the cutting step, the cutting may be performed by using a curl hook. The curved saddle has two blade portions and two handle portions. The two blade parts are cut across the hair. The two handle portions extend from the roots of the respective blade portions. Each of the two handle portions has an insertion space in which a finger is arranged, and the blade portion connected to the handle portion is displaced by a force applied from the finger arranged in the insertion space. Then, cut. In addition, the insertion space extends along a predetermined insertion surface. Further, the portion including at least the tip of the two blade portions is displaced along a predetermined reference plane when cutting. The insertion surface is inclined with respect to the reference surface so as to move away from the reference surface as the distance from the tip of the blade portion increases.

  By cutting the hair bundle along the inclined cut line with the bending fold, the orientation of the insertion surface of the handle portion can be made closer to the direction orthogonal to the extending direction. This makes it possible to hold a bag with a more comfortable posture. Therefore, it becomes easy to cut the inclined cut line.

In addition, the direction from one of the two handle portions toward the other may be a twist direction, and the insertion surface may be further inclined with respect to the reference surface so as to approach the reference surface as it goes in the twist direction.
When cutting the hair bundle along the inclined cut line with such a twisted bent ridge, when the blade portion of the bent ridge is placed along the inclined cut line, the insertion surface of the handle portion is on the right side in the extension direction or It will be tilted to the left. For this reason, the provider who cuts a recipient's hair can arrange a hand in the lower right or lower left of a hair bundle, and can operate the curl. Therefore, it is possible to hold the heel with a more comfortable posture, and it becomes easy to cut along the inclined cut line.

  Moreover, the twist bend crease according to one aspect of the present disclosure is a crease for cutting the hair. The torsion-curved scissors include two blade portions that are cut across the hair and two handle portions that extend from the roots of the respective blade portions. Each of the two handle portions has an insertion space in which fingers are arranged, and by displacing a blade portion connected to the handle portions by a force applied from the fingers arranged in the insertion space, Disconnect. In addition, the insertion space extends along a predetermined insertion surface. Further, the portion including at least the tip of the two blade portions is displaced along a predetermined reference plane when cutting. In addition, the insertion surface is inclined with respect to the reference surface so as to move away from the reference surface as the distance from the tip of the blade portion increases. The direction from one of the two handle portions toward the other is the twist direction, and the insertion surface is further inclined with respect to the reference surface so as to approach the reference surface as it goes in the twist direction.

  The positional relationship between the hand and the blade portion when operating such a twisted curved scissors is different from the positional relationship when operating a normal scissors. For this reason, even if it is a cut line that is difficult to cut with a normal scissors, it is possible to cut with an easy posture by using a twisted curled scissors. In other words, even a cutting line that has been difficult to cut in the past can be cut more accurately and easily by using a twisted bend. For this reason, it becomes possible to improve the appearance of the hair.

  In addition, the twist bend wrinkle may be used in a predetermined hair cutting method for cutting the hair of the recipient. That is, the hair cutting method includes an extraction step, a support step, and a cutting step. The extraction step is to determine the direction of hair flow that is the direction in which the hair to be cut extends, and from the elongated region that is located at the root of the hair in the scalp of the recipient and extends along the direction of hair flow. This is a step of taking out a hair bundle that is a bundle of hair. Further, the support step is a step of supporting the taken out hair bundle at a support position, and spreading the hair bundle in a strip shape and extending in the extending direction from the support position toward the root of the hair bundle. is there. The cutting step is a step of cutting the supported hair bundle along an inclined cut line that is inclined with respect to the extending direction. Moreover, let the edge part located in the opposite side of a hair flow direction among the edge parts of the width direction in the supported hair | bristle bundle be a longitudinal side. The inclined cut line is a line that inclines away from the scalp as it goes to the longitudinal side.

  When a hair bundle is cut along the inclined cut line with such a twisted beak, when the blade portion of the twist bend is placed along the inclined cut line, the insertion surface of the handle is on the right side in the extension direction. Or it will be in the state leaning to the left. For this reason, the provider who cuts the hair of the recipient can place the hand on the lower right or lower left of the hair bundle and can operate the twisted beard. Therefore, it is possible to hold the heel with a more comfortable posture, and it becomes easy to cut along the inclined cut line.

Hereinafter, embodiments for carrying out the present disclosure will be described with reference to the drawings.
[First Embodiment]
[1. About Overview]
The hair cutting method according to the first embodiment is a method for suppressing the jumping and undulation of the hair due to curly hair. Curly hair means hair that has been curly. According to the hair-cutting method, when the natural hair quality is curly hair and when the hair is curly hair by applying a permanent hair, splashing and undulation are suppressed. Hereinafter, a person who cuts hair is referred to as a provider, and a person whose hair is cut by the provider is referred to as a recipient. Moreover, the part which the head hair has grown in the recipient's head is described as the scalp.

  As shown in FIG. 1A, the recipient's scalp 1 has three regions A to C zones 10 to 30. Then, the hair is cut by a method corresponding to the region. First, a method for setting the A to C zones 10 to 30 will be described.

  The scalp 1 has a part called a bee. A bee is a region in the scalp 1 that is located at or near the boundary between the temporal region, the occipital region, and the apex, and protrudes laterally. Here, the left and right edges of the recipient's forehead are referred to as side edges. The bee is an elongated portion that extends from one side edge of the forehead of the recipient to cross the left and right temporal and occipital areas to reach the side edge of the other forehead. A bee line 2 in FIG. 1A indicates the position of the bee. The scalp 1 also has a portion called a bon pit 3. The bon pit 3 is the most depressed part in the back of the head.

  The A zone 10 is located below the A / B line 5. Here, a position slightly below the end of the bee line at the side edge of the forehead (as an example, a position approximately 1 cm below the end) is referred to as an A / B line end. The A / B line 5 draws a gentle curve from the end of the A / B line at the side edge of one of the foreheads to the hollow 3. Further, the A / B line 5 extends from the pit 3 to the end of the A / B line at the side edge of the other forehead while drawing a similar curve.

  The B zone 20 is located between the B / C line 6 and the A / B line 5. Here, a position slightly above the edge of the bee line 2 at the side edge of the forehead (as an example, a position approximately 1 cm above the edge) is referred to as a B / C line edge. The B / C line 6 is located above the bee line 2. The B / C line 6 is spaced from the bee line 2 at a constant or substantially constant interval from the end of the B / C line at the side edge of one forehead to the end of the B / C line at the side edge of the other forehead. Extend.

The C zone 30 is located above the B / C line 6.
[2. About haircut method]
Next, the haircut method of the first embodiment will be described in detail with reference to FIG. 1B. The haircut method has steps S100 to S110. The provider performs these steps once or a plurality of times when cutting the recipient's hair. At this time, the hair cutting method is applied to the hair in all or part of zones A to C 10-30. The hair cutting method is applied to all or a part of the hair in each zone.

  In S <b> 100, the provider specifies a portion to be cut in the recipient's hair, and determines a hair flow direction that is a direction in which the hair forming the portion extends. The hair flow direction is determined according to, for example, the direction in which the recipient's hair grows, the hairstyle, and the like. Specifically, for example, the direction in which the hair extends naturally determined by the direction in which the recipient's natural hair grows may be used as the hair flow direction. In addition, for example, the direction in which the hair extends in accordance with the hairstyle desired by the recipient may be set as the hair flow direction. In addition, the hair flow direction of the A and B zones 10 and 20 may be a downward direction as an example. Further, the hair flow direction of the C zone 30 may be, for example, a direction toward the front, back, side, or downward.

  And a provider takes out the hair bundle which is located in the base of the hair which discriminate | determined the hair flow direction, and is the hair bundle which grows in the elongate area | region (henceforth an extraction area | region) extended along this hair flow direction. . At this time, it is preferable to take out all the hairs growing in the take-out area. Further, the width of the extraction region may be about 1 cm as an example. As a specific example, the provider places a hand that is not a dominant hand along the direction of the hair flow or the direction opposite to the direction of the hair flow (in other words, 鋏The index finger and middle finger of the hand that does not have the hand may be inserted. At this time, the index finger and the middle finger are in an extended state with an interval (about 1 cm as an example). For this reason, the hair enters between these fingers. Then, the provider may pinch the hair with these fingers and take out the pinched hair as a hair bundle. In this case, the length of the extraction area is approximately the same as the length of the index finger and middle finger of the provider.

  In subsequent S105, as shown in FIG. 2, the provider supports the taken-out hair bundle 200 at a support position 203 located at or near the tip of the hair bundle. The supported hair bundle 200 is in a state of being spread in a band shape and extending from the support position 203 in the extending direction 205 toward the root of the hair bundle (hereinafter referred to as a support state). At this time, the width of the hair bundle 200 and the length of the extraction region may be approximately the same.

  Specifically, when the hair bundle 200 is taken out with the index finger and middle finger of the non-dominant hand by the above-described method, as an example, the provider supports the index finger and middle finger 50 holding the hair bundle 200 as they are. The position 203 may be moved. Then, the provider may hold the hair bundle 200 at the support position 203 so that the hair bundle 200 is supported. At this time, at the support position 203, the hair bundle 200 is sandwiched from both sides by the index finger and the middle finger 50. For this reason, the width | variety of this hair | bristle bundle 200 becomes comparable as the length of a provider's index finger and middle finger 50. FIG. At this time, the back of the hand of the provider holding the hair bundle 200 is located above or below the hair bundle 200. In addition, each hair included in the hair bundle 200 is desirably in a state of extending linearly or substantially linearly from the position where the hair grows in the same direction or substantially in the same direction. In FIG. 2, as an example, the width direction of the hair bundle 200 coincides with the hair flow direction 206. However, depending on the direction of the extension direction 205, it may be assumed that the width direction of the hair bundle 200 does not coincide with the hair flow direction 206.

  Here, the direction opposite to the extending direction in the hair bundle in the supported state is referred to as an extraction direction. As shown in FIG. 1A, the angle 40a between the direction 40 of the hair bundle taken out from the A zone 10 of the scalp 1 of the provider and in a supported state and the direction 41 downward in the vertical direction is approximately 0. It is in the range of ° to 90 °. Further, the angle 42a between the direction 42 of the hair bundle taken out from the B zone 20 and in a supported state and the direction 41 downward in the vertical direction is in the range of about 15 ° to 120 °. Further, the angle 43a between the direction 43 of the hair bundle taken out from the C zone 30 and in a supported state and the direction 44 extending horizontally in front of the recipient is in the range of approximately 15 ° to 90 °. At the top of scalp 1 in C zone 30 (in other words, the top of the head), the maximum value of angle 43a may exceed 90 °.

  In subsequent S <b> 110, the provider cuts the supported hair bundle 200 along an inclined cut line 210 that is inclined with respect to the extension direction 205, as shown in FIG. 3. At this time, the provider may cut by opening and closing the ridges in small increments. Thereby, damage to the hair is suppressed.

  Here, among the end portions in the width direction of the supported hair bundle 200, those positioned on the side of the hair flow direction 206 are referred to as the short side 201, and those positioned on the opposite side of the hair flow direction 206 are referred to as the long side. 202. The width of the hair bundle 200 is described as H.

  The inclined cut line 210 is inclined with respect to the extending direction 205 so as to move away from the scalp toward the longitudinal side 202. As an example, in FIG. 3, the angle of the inclined cut line 210 with respect to the extension direction 205 becomes smaller toward the longitudinal side 202. In other words, the inclination of the inclined cut line 210 becomes smaller with respect to the extending direction 205 as it goes toward the longitudinal side 202. The inclined cut line 210 may be inclined with respect to the extending direction 205 with a certain degree. That is, the inclined cut line 210 may extend linearly or substantially linearly.

  The inclined cut line 210 has A point 211 to D point 214. The point A 211 is located on the short side 201. The range of the distance Hab in the width direction between the point A 211 and the point B 212 is approximately H / 3 to H / 2. Further, the distance Hbc in the width direction between the point B 212 and the point C 213 is approximately (H−Hab) / 3. Further, the point D 214 is located on the long side 202 or near the hair tip.

  In the inclined cut line 210, the section from the point A 211 to the point B 212 is the section AB, the section from the point B 212 to the point C 213 is the section BC, and the section from the point C 213 to the point C ′ 213a is The CC ′ section and the section from the C ′ point 213a to the D point 214 are referred to as a C′D section. These sections extend linearly or substantially linearly. In the first embodiment, as an example, the angle a with respect to the extension direction 205 of the AB section is about 45 °, the angle b with respect to the extension direction 205 of the BC section is about 30 °, and the angle c with respect to the extension direction 205 of the CC ′ section is It is about 15 °. The length of the CC ′ section is about 2 to 3% of the distance of the straight line connecting the C point 213 and the D point 214. The angle of the C′D section with respect to the extension direction 205 is smaller than the angle c.

  The provider performs cutting in the order of the AB section, the BC section, the CC ′ section, and the C′D section. After the cut to the point C ′, the cut is made toward the point D 214 in a direction having a slight inclination with respect to the extension direction 205.

  Further, the position or shape of the inclined cut line may be adjusted as follows according to the amount of hair of the recipient. As a result, more hair is cut as the amount of hair increases. As a result, it is possible to suitably suppress waviness and the like while adjusting the amount of hair.

  Specifically, L is the length in the extension direction 205 of the supported hair bundle 200. In the hair bundle 200, a position approximately L / 6 away from the root in the extending direction is L1, a position approximately 2 × L / 6 away from the root in the extending direction is L2, and a position approximately 3 × in the extending direction from the root. A position L / 6 away is referred to as L3.

  When the recipient's hair volume is large, the point A may be set in a section 221 between L1 and L2 in the supported hair bundle 200. Further, when the hair volume of the recipient is standard, a point A may be set in a section 220 between L2 and L3 in the hair bundle 200. At this time, the length of H or Hab is adjusted according to the position of the point A.

  Further, when the hair amount of the recipient is small, points B to D may be provided without providing the point A on the inclined cut line. Specifically, the provider may set point B in the section 220 on the short side 201. The provider may set the point C so that the angle b is 30 ° and the Hbc is approximately H / 3. In addition, the provider sets the C ′ point so that the angle c is about 15 °, and the length of the CC ′ section is about 2-3% of the distance of the straight line connecting the C point and the D point. May be. Further, the provider may set the point D on the hair tip on the long side 202 or in the vicinity thereof. At this time, the angle of the C′D section with respect to the extension direction 205 is smaller than the angle c.

  Then, the provider performs cutting in the order of the BC section, the CC ′ section, and the C′D section. After the cut to the point C ′, the cut is made toward the point D 214 in a direction having a slight inclination with respect to the extension direction 205.

[3. About Curved］]
In S110 of the hair cutting method of the first embodiment, when the head hair is cut along the inclined cut line 210, the bend fold 300 of FIGS. 4A and 4B may be used.

The bending rod 300 has two first and second blade portions 310 and 311, two first and second handle portions 320 and 330, and a shaft portion 340.
The first and second blade portions 310 and 311 extend linearly, and are attached to the shaft portion 340 at the roots thereof. The first and second blade portions 310 and 311 are cut in such a manner that the hair is sandwiched by being displaced in the direction of rotation about the shaft portion 340. At this time, the first and second blade portions 310 and 311 are displaced along the reference surface 350. The reference surface 350 is a flat surface as an example.

  On the other hand, the first handle portion 320 extends from the end portion on the base side of the first blade portion 310. Further, the second handle portion 330 extends from the end portion on the base side of the second blade portion 311. The first and second handle portions 320 and 330 have insertion spaces 321 and 331, respectively, in which the provider's fingers are arranged. The insertion spaces 321 and 331 of the handle portions are flat spaces that extend along predetermined insertion surfaces 321a and 331a. The insertion surfaces 321a and 331a are flat as an example.

  The insertion space 321 of the first handle part 320 is surrounded by a finger insertion part 322 that is an annular part. In addition, the insertion space 331 of the second handle 330 is surrounded by a finger insertion part 332 that is an elongated part curved in a C shape. For example, an index finger, a middle finger, or a ring finger may be arranged in the insertion space 321 of the first handle part 320, and a thumb may be arranged in the insertion space 331 of the second handle part 330. The two handle portions 320 and 330 displace the two blade portions 310 and 311 in a direction to rotate around the shaft portion 340 by a force applied from a finger arranged in the insertion space. As a result, the hair is cut.

  The first and second handle portions 320 and 330 are bent at bending points 323 and 333 located on the blade portions 310 and 311 side of the finger insertion portions 322 and 332, respectively. That is, the insertion surfaces 321 a and 331 a related to the insertion space of these handle portions are inclined with respect to the reference surface 350. The insertion surfaces 321a and 331a are inclined with respect to the reference surface 350 so as to move away from the reference surface 350 as it goes in the root side direction. The root side direction means a direction from the tips of the first and second blade portions 310 and 311 toward the root. In other words, the insertion surfaces 321 a and 331 a are inclined with respect to the reference surface 350 so as to move away from the reference surface 350 as the distance from the tips of the first and second blade portions 310 and 311 increases.

  Here, the angle at which the insertion surface 321a corresponding to the first handle 320 intersects the reference surface 350 is defined as θ1. In addition, an angle at which the insertion surface 331a corresponding to the second handle portion 330 and the reference surface 350 intersect is defined as θ2. As an example, it is conceivable that θ1 and θ2 are in a range of approximately 20 ° to 40 °. As an example, the angles θ1 and θ2 may be approximately 30 °. In the first embodiment, θ1 and θ2 are the same angle, but they may be different angles.

  Note that the bending rod 300 may be bent at bending points provided in the first and second blade portions 310 and 311. In this case, when the hair is cut, a portion of the first and second blade portions 310 and 311 closer to the tip than the bending point and a portion closer to the root than the bending point are displaced along different reference planes. The insertion surfaces 321a and 322a are similarly inclined with respect to the reference surface corresponding to the tip side portion.

  Next, referring to FIG. 5A, a usage mode in the case where cutting is performed along the inclined cut line 210 of the hair bundle 200 using the bending fold 300 will be described. It is preferable that the provider uses the curled fold 300 with the insertion surfaces 321a and 331a inclined toward the hair tip side with respect to the reference surface 350.

[4. About torsion-curved crab]
In S110 of the haircut method of the first embodiment, the twisted bend 400 in FIGS. 5B, 6A, and 6B may be used instead of the bend beak 300 described above. In addition, the torsion bend 400 has a right-handed configuration that is assumed to be used by the provider with the right hand.

The torsion bend 400 includes two first and second blade portions 410 and 411, two first and second handle portions 420 and 430, and a shaft portion 440.
The first and second blade portions 410 and 411 and the shaft portion 440 have the same configuration as the first and second blade portions 310 and 311 and the shaft portion 340 of the bending rod 300. When cutting the hair, the first and second blade portions 410 and 411 are displaced along the reference plane 450. The reference surface 450 is a flat surface as an example.

  Further, similarly to the first and second handle portions 320 and 330 of the bending rod 300, the first handle portion 420 is from the end on the root side of the first blade portion 410, and the second handle portion 430 is the end of the second blade portion 411. Each extends from the end on the root side. The first and second handle portions 420 and 430 have insertion spaces 421 and 431 in which the provider's fingers are arranged, respectively. The insertion spaces 421 and 431 of the respective handle portions are flat spaces that extend along predetermined insertion surfaces 421a and 431a. The insertion surfaces 421a and 431a are flat as an example.

  The insertion space 421 of the first handle portion 420 and the insertion space 431 of the second handle portion 430 are respectively surrounded by finger insertion portions 422 and 432 that are annular portions. In addition, as with the bent rod 300, for example, an index finger, a middle finger, or a ring finger is arranged in the insertion space 421 of the first handle 420, and a thumb is arranged in the insertion space 431 of the second handle 430. Also good. Then, the two handle portions 420 and 430 displace the two blade portions 410 and 411 in the same manner as the first and second handle portions 320 and 330 of the bent heel 300, whereby the hair is cut.

  And as FIG. 6A shows, the 1st, 2nd handle | pattern parts 420 and 430 are the bending points 423 and 433 located in the blade parts 410 and 411 side of the finger insertion parts 422 and 432, respectively, similarly to the bending rod 300. And bent. That is, the insertion surfaces 421 a and 431 a related to the insertion space of these handle portions are inclined with respect to the reference surface 450 in the same manner as the bending rod 300. The insertion surfaces 421a and 431a are inclined with respect to the reference surface 450 so as to move away from the reference surface 450 as the distance from the distal ends of the first and second blade portions 410 and 411 increases.

  In addition, 421a in FIG. 6A shows the part extended in the extending | stretching direction of the 1st handle part 420 from the bending point 423 in the insertion surface of the 1st handle part 420. FIG. In addition, 431a in FIG. 6A indicates a portion of the insertion surface of the second handle portion 430 that extends from the bending point 433 in the extending direction of the second handle portion 430.

  The first handle 420 is located on the right side of the second handle 430 in the direction in which the first and second handles 420 and 430 are bent. In addition, an angle θ1 at which the insertion surface 421a corresponding to the first handle 420 intersects the reference plane 450 and an angle θ2 at which the insertion surface 431a corresponding to the second handle 430 intersects the reference plane 450 are bent. It may be the same as 300. Further, similarly to the bending rod 300, the twisted bending rod 400 may be bent at the bending points provided in the first and second blade portions 410 and 411.

  Here, the direction from the second handle portion 430 toward the first handle portion 420 is defined as a twist direction 460. The twist direction 460 may be a direction from the second handle portion 430 toward the first handle portion 420 along the reference plane 450. That is, the direction in which the first and second blade portions 410 and 411 extend along the reference surface 450 when the first and second blade portions 410 and 411 are completely closed is referred to as an extending direction 451. In other words, the extension direction 451 is a direction along the reference plane 450 from the shaft portion 440 toward the tips of the first and second blade portions 410 and 411 that are completely closed. The twist direction 460 may be a direction orthogonal to the extension direction 451 along the reference surface 450.

  6B, the insertion surfaces 421a and 431a are further inclined with respect to the reference surface 450 so as to approach the reference surface 450 in the twist direction 460. In addition, 421a in FIG. 6B indicates a portion of the insertion surface of the first handle 420 that extends in the twist direction 460 at the center of the insertion space 421. In addition, 431a in FIG. 6B indicates a portion of the insertion surface of the second handle 430 that extends in the twist direction 460 in the center of the insertion space 431.

  In other words, the insertion surface 421a is arranged such that the line of intersection between the insertion surface 421a of the first handle 420 and the reference surface 450 moves away from the tips of the first and second blade portions 410, 411 as it goes in the twisting direction 460. It is inclined with respect to the reference plane 450. In addition, the insertion surface 431a is inclined with respect to the reference surface 450 so that the line of intersection between the insertion surface 431a of the second handle 430 and the reference surface 450 moves away from the tip as it goes in the twisting direction 460. Further, the angle of the twist direction 460 between the insertion surface 421a of the first handle 420 and the reference surface 450 is defined as a twist angle θ3. Further, the angle of the twist direction 460 between the insertion surface 431a of the second handle 430 and the reference surface 450 is defined as a twist angle θ4. θ3 and θ4 have any value in the range of 10 ° to 60 °. More preferably, θ3 and θ4 may be any value in the range of 20 ° to 45 °.

  As an example, the left-handed twisted beak 400 that is assumed to be used by the provider with the left hand is provided with a thumb in the insertion space 421 of the first handle 420 and the insertion of the second handle 430. An index finger, a middle finger, or a ring finger may be arranged in the space 431. In addition, the twisting direction of the left-handed twisted bending rod 400 is set in the direction opposite to that of the right-handed one. Further, the insertion surfaces 421a and 431a are inclined with respect to the reference surface 450 so as to approach the reference surface 450 as it goes in the twisting direction, similarly to the right-handed twisted beak 400.

  Next, referring to FIG. 7, a usage mode in the case where cutting is performed along the inclined cut line 210 of the hair bundle 200 using the right-handed twisted beak 400 will be described. It is preferable that the provider uses the twisted beard 400 with the insertion surfaces 421a and 431a inclined toward the hair tip side with respect to the reference surface 450. At this time, the insertion surfaces 421a and 431a (in other words, the insertion spaces 421 and 431) are inclined rightward in the extending direction 205.

[5. effect]
According to the first embodiment, the following effects can be obtained.
(1) According to the hair cutting method of the first embodiment, the length of the hair in the hair flow direction side of the hair bundle taken out in S100 is shorter than that of the hair on the opposite side in the hair flow direction. A hair bundle 500 in FIG. 8 shows a set of hair bundles taken out in S100, which are arranged in a direction orthogonal to the hair flow direction 501. As shown in FIG. 8, as a result of performing the hair cutting method, the hair bundle 500 is curved in a C shape in the hair flow direction 501. Thus, the hair bundle 500 extends in the direction of hair flow while curving in a C shape on the scalp side. For this reason, for example, when the hair quality of the hair is curly hair, it is possible to suppress the hair bundle 500 from undulating in an S shape or jumping outward. Therefore, the appearance of the hair can be improved.

  (2) In addition, the angle of the inclined cut line 210 with respect to the extension direction 205 becomes smaller toward the longitudinal side 202. For this reason, each hair bundle taken out in S100 can be appropriately curved in a C shape. Therefore, the appearance of the hair can be improved.

  (3) Moreover, when the curved hook 300 is used, it becomes possible to make the direction of the insertion surfaces 321a and 331a in the handle portions 320 and 330 of the curved hook 300 closer to the direction orthogonal to the extending direction. For this reason, the provider can hold the bag with a more comfortable posture. Therefore, cutting along the inclined cut line 210 is facilitated.

  (4) Further, when cutting along the inclined cut line 210 using the twisted bending rod 400, when the first and second blade portions 410, 411 are moved along the inclined cut line 210, the first and first The insertion surfaces 421a and 431a of the two handle portions 420 and 430 are inclined rightward in the extension direction 205. For this reason, the provider can arrange the right hand in the lower right of the hair bundle 200 and can operate the twisted bend 400. Therefore, it becomes possible to hold the bag with a more comfortable posture, and the cutting becomes easy.

  (5) Further, the positional relationship between the right hand that operates the twisted and bent rod 400 and the blade portion is different from the positional relationship when operating a normal rod. For this reason, even if the cut line is difficult to cut with a normal scissors, the use of the twisted curled scissors 400 makes it possible to cut with an easy posture. That is, even if the cutting line has been difficult to cut in the past, it is possible to cut more accurately and easily by using the twisted beard 400. For this reason, it becomes possible to improve the appearance of the hair.

[Second Embodiment]
[1. About differences]
Since the basic structure of the haircut method of 2nd Embodiment is the same as that of 1st Embodiment, a difference is demonstrated below. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and the preceding description is referred to.

  The haircut method of the second embodiment is different from the haircut method of the first embodiment in S110. That is, as shown in FIG. 9, in the second embodiment, a step cut line 230 is provided in addition to the inclined cut line 210 for the supported hair bundle 200. The step cut line 230 extends linearly or substantially linearly in a state orthogonal or substantially orthogonal to the extending direction 205 of the hair bundle 200. The step cut line 230 extends from the E point 231 on the short side 201 of the supported hair bundle 200 to the A point 211 of the inclined cut line 210.

  Here, a line that passes through the point A 211 that is the end of the step cut line 230 and extends in the extension direction 205 is defined as a boundary line 215. The inclined cut line 210 of the second embodiment is determined in the same manner as the hair cut method of the first embodiment. That is, the portion between the boundary line 215 and the long side 202 in the supported hair bundle 200 is regarded as the whole supported hair bundle, and the inclined cut line is determined in the same manner as in the first embodiment.

  Further, the distance in the width direction between the E point 231 and the A point 211 is assumed to be Hea. Further, the distance in the width direction between the point A 211 and the long side 202 is defined as Had. Hea is approximately less than Had / 2.

  The step cut line 230 may be inclined in the opposite direction to the inclined cut line 210. That is, the step cut line 230 may be inclined with respect to the extending direction 205 so as to approach the scalp as it goes toward the longitudinal side 202. In this case, the range of the angle at which the step cut line 230 is inclined with respect to the direction orthogonal to the extending direction 205 may be approximately 0 ° to 25 °.

  Further, the step cut line 230 may be inclined in the same direction as the inclined cut line 210. In other words, the step cut line 230 may be inclined with respect to the extension direction 205 so as to move away from the scalp toward the longitudinal side 202. In this case, the range of the angle at which the step cut line 230 is inclined with respect to the direction orthogonal to the extending direction 205 may be approximately 0 ° to 25 °.

  In addition, also in S110 in the hair cutting method of 2nd Embodiment, in the case of the cutting of the inclination cut line 210, the bending rod 300 or the bending rod 400 with a twist may be used. Of course, also when the step cut line 230 is cut, the bent hook 300 or the twisted bent hook 400 may be used.

[2. effect]
According to the second embodiment, the effects (1) to (3) of the first embodiment are exhibited, and the following effects are further achieved.

  That is, in the hair cutting method of the second embodiment, a step cut line 230 is provided in addition to the inclined cut line 210. For this reason, the portion (hereinafter referred to as an inclined portion) cut along the inclined cut line 210 in each hair bundle 200 taken out in S100 is an inclined portion of another hair bundle 200 adjacent to the hair flow direction. It will be in the state with a space | interval between. For this reason, it can suppress that the inclined part in each hair | bristle bundle 200 gets entangled, and the touch and finger passage of hair become favorable.

[Other Embodiments]
As mentioned above, although the form for implementing this indication was demonstrated, this indication is not limited to the above-mentioned embodiment, and can carry out various modifications.

  (1) In the hair cutting methods of the first and second embodiments, the hair bundle is taken out by the provider's index finger and middle finger. However, the method for taking out the hair bundle is not limited to such a method. Specifically, the provider may take out the hair bundle using, for example, an instrument.

  (2) The inclined cut line 210 in the first and second embodiments is inclined so as to move away from the scalp toward the longitudinal side 202, and has A points 211 to D 214. However, the number and position of these points are not limited to those described in the first and second embodiments. In addition, the inclined cut line 210 has one end reaching the longitudinal side 202 but may not reach the longitudinal side 202. That is, the hair near the longitudinal side 202 in the supported hair bundle 200 may not be cut.

  (3) The hair cutting methods of the first and second embodiments are not limited to curly hair and can be applied to hair of various hair qualities. Even in such a case, the hair can be naturally curved and the appearance of the hair can be improved.
