Description

The invention relates to the field of hairdressing, and in particular to methods for changing the length of short hair to longer hair and increasing the volume of hair [A41G 5/00, A41G 5/004, A41G 5/0046, A41G 5/0053, A41G 5/0066].

From the prior art known HAIR EXTENSION METHOD [US2009188514 (A1), publ.: 30.07.2009], which includes the following steps: preparation of hair extensions depending on the hairstyle and length of the original hair; grouping, including the action of dividing the original hair into an upper region near the top of the head; and the lower region near the neck; group the lower region into several initial groups of hair, each of which has an end and several strands; and also group hair extensions into several groups of hair extensions, corresponding in number to the original hair groups; and each group of hair extensions having an end and a plurality of strands substantially corresponding in number to the number of strands of the respective original hair group; gluing, including the steps of preparing a sleeve with hot melt adhesive on each group of hair extensions; the end of each group of hair extensions and the end of the corresponding original group of hair are adjacent and overlap each other, forming an overlapping section; and the overlapping section is mixed with adhesive and subjected to hot pressing; wrapping, including the act of sliding a sleeve of hot melt over an overlapping section; the hot melt adhesive sleeve is hot pressed and melted around the overlapping section to further bond the extension hair group and the original hair group together; and shaping, wherein the top of the original hair is laid to cover the overlapping portions, and the original hair is further styled.

Also known is a METHOD OF ATTACHING ADDITIONAL HAIR TO HUMAN HAIR [US2004168699 (A1), publ.: 09/02/2004], including the following steps: selecting a plurality of strands of human hair growing on the scalp; direct contact of the glued part of the additional hair bundle with the heating element and fusing the glued part to change the glued part from the hardened state to the working viscosity, while the additional hair bundle includes a plurality of additional strands glued to each other on the glued part with thermoplastic adhesive, and also clamped the glued portion of the additional hair bundle together with the selected plurality of human hair strands using a heating element and allowing the thermoplastic adhesive to be mixed with the plurality of human hair strands. The method further includes the step of forming a joint between the human hair strands and the additional hair bundle and directly contacting the joint with the heating element and the step of clamping the glued part of the additional hair bundle in the solidified state to the selected plurality of human hair strands using the heating element and fusing the glued part.

The closest in technical essence is the METHOD OF HIDDEN HAIR FASTENING [RU2756269 (C1), publ.: 29.09.2021], including:

- preliminary hair preparation, in which at least one base - a hair web - is isolated and a donor strand is prepared;

- the beginning of the formation of a fixing capsule, in which the base is pulled and smoothed - the hair web - with one hand, the donor strand is inserted into the base-web and their mutual fixation with the other hand;

- and gluing the donor strand, in which glue is applied to the cut of the upper part of the donor strand, pressed against the base - the hair sheet, impregnated with glue, while one of the hands fixing the donor strand performs constant tactile control of the tension of the donor strand and base - hair sheets, then with one hand they stretch and fix the base - the hair sheet - with the donor strand, and with the other hand they fold the base - the hair sheet - in half, wrapping the donor strand, and make an additional turn with the hand with the base - the hair sheet, without opening the fingers, complete wrapping, after that, the formation of the fixing capsule is completed by uniform compaction with the fingers, at the end of which an activator is applied, characterized in that cyanoacrylate glue is used as an adhesive, while the formation of the fixing capsule is made conical, expanding towards the bottom, and during preliminary preparation, the hair structure is determined, depending on which the amount and place of the applied activator are chosen.

The main technical problem of analogues and prototypes is the high complexity of the hair extension procedure due to the alignment and encapsulation of each of the strands of donor hair separately, which ultimately leads to a decrease in the quality of the procedure due to the accumulation of fatigue of the master, loss of attention by the master and deterioration of his coordination. movements, increased muscle tone (spasticity), which additionally leads to various motor disorders. In addition, increasing the time to complete the procedure invariably leads to an increase in the cost of the procedure for the client.

The objective of the invention is to eliminate the disadvantages of analogs and prototype.

The technical result of the invention is to reduce the complexity of the hair extension procedure and improve the quality of the procedure.

The specified technical result is achieved due to the fact that the method of hair extension, characterized by the selection of the patient's own strand of hair, the preparation of the donor strand, the connection of the own and the donor strands with an adhesive method, characterized in that the section of the donor hair that has undergone the initial mechanical, thermal and chemical treatment is clamped in the palm of the hand, so that the said section protrudes 2-4 cm outward from the hand, while the protruding section is clamped between the index and thumb fingers of the same hand, the tips of the protruding section are aligned and, temporarily loosening the fixation with the thumb, evenly distribute the section on the index finger with a fan , a pre-melted adhesive capsule is applied to a section of donor hair protruding from the palm, thereby forming an adhesive base with a width of 4 to 10 mm above and below the fan of the donor hair section, after the formation of the adhesive base of the donor hair section and the glue solidifies, holding the donor hair section at the base comb it and re-align the edge of the cut with scissors along the adhesive base, leaving the adhesive base 1-3 mm wide, and divide the prepared section of donor hair into strands for their connection with the selected own strand by placing the donor strand with the adhesive base under one's own strand, followed by heating the adhesive base and formation of a fixing capsule around the donor and own hair strands by uniform compaction with the fingers of the hand.

Implementation of the invention.

The hair extension procedure consists of preliminary, main and final stages. The preliminary stage includes the consultation and preparation of donor yarns, the main stage includes the preparation of the client's own hair and the extension of donor hair to the client's own hair, and the final stage includes the final processing of the hair.

Preliminary stage.

At the consultation, the desired goal is determined (increasing the length of all hair, creating a complex hairstyle, selectively adding colored strands, etc.), the type of hair extension, making sure that the length and quality of the client's own hair is suitable for extension. A consultation can be held in advance, not necessarily on the day of the extension procedure in order to give the master time to prepare the donor strands.

Preparation of donor strands. The initial mechanical, thermal and chemical treatment, as well as division into strands, takes place at the factory, the hair comes to the salon in a prepared form in the form of a cut. The stage of preparing donor strands includes applying an adhesive strip to the cut of donor strands. To do this, the tongs are heated, and with the help of the said tongs, the adhesive capsule is heated until it softens. The tongs with the melted adhesive capsule are left on the table.

Further, the master takes a section of donor hair, puts it in the palm so that the said section protrudes upwards from the hand, while the master places the section on the I-III phalanges of the index finger and fixes it in the palm, pressing it on the index finger with the thumb of the same hand and three other fingers in the palm. The protruding part of the cut of donor hair will be the base. The section from the index finger should protrude mainly by 2-4 cm. This is due to the fact that if the length of the protruding section is more than 4 cm, the mentioned section of donor hair will bend under the action of its own gravity and further operations to prepare the section of donor hair for extension will be difficult from the point of in terms of the accuracy of the formation of the base of donor hair. If the length of the protruding cut is less than 2 cm, the difficulty in forming the base will be associated with the risk of burns from hot tongs, and also with the fact that part of the cut is closed with the thumb, which presses the donor hair cut to the index finger.

Next, the master aligns the ends of the protruding section of donor hair with scissors and, loosening the fixation with his thumb, evenly distributes the section on the index finger with a fan, after which he again fixes the section of donor hair with his thumb to the index finger.

In the next operation of the stage, the master applies a pre-melted glue capsule with tongs to a section of donor hair protruding from the palm, thereby forming an adhesive base for the donor hair section. When applying glue, the master ensures its uniform application from above and below the cut to a strip 4 to 10 mm wide along the edge of the cut and withstands the time until the applied glue hardens. Such a width of the adhesive base is due to the fact that with its width less than 4 mm, when further leveling the cut, the master will not always be able to do it evenly, since when applying glue to a cut of donor hair, a violation of the cut edge is inevitable and for alignment it is necessary to cut off the cut edge together with adhesive base, taking into account the fact that the final width of the base should be 1-3 mm. The width of the adhesive base of more than 10 mm leads to an increased consumption of the adhesive capsule and the adhesive that the master previously prepared simply may not be enough to cut the donor hair. In this case, the master will have to prepare a new portion of the glue, and at this time the glue already applied to the cut of the donor hair will harden and re-melting it to apply a new portion of the glue leads to overheating of the donor hair and can lead to their destruction.

After the glue base of the donor hair section is formed and the glue hardens, the master, holding the donor hair section at the base, combs it and aligns the cut with scissors along the glue base, leaving the glue base 1-3 mm wide.

This completes the preliminary stage.

At the request of the client, the preliminary and main stages are carried out on the same day sequentially or the operations for preparing donor strands are combined with the main stage.

Main stage.

Preparation of the client's own hair. Hair must be clean, free from styling products, grease. If you want to change the color of the base hair, perm or straighten - these procedures are also performed at this stage of the main stage.

Building. The master lays the prepared section of donor hair with an adhesive base formed on it in the form of an adhesive strip on the working surface in an accessible place for work and divides it into strands with a thickness depending on the quality of the client’s own hair and the goal determined at the consultation. The thickness of the strand of donor hair should preferably correspond to the thickness of the strand of the client's own hair.

On the client’s head, using a comb or a pointed stick, a strand of own hair of the required thickness is isolated, combed and holding the selected strand with one hand, take a strand of donor hair with the other hand and lead it with an adhesive base under the strand of the patient’s own hair to the attachment point, pressing the strand of donor hair with the adhesive base to own strand of hair.

Holding the strands of donor and own hair in the place of their fastening with the fingers of one hand, with the other hand they take the forceps and intercept the place of the mentioned connection with them. While holding the tongs, the glue of the adhesive base of the strand of donor hair is heated. After warming up and softening the glue of the adhesive base, the forceps are removed, and with the fingers of the second hand, the formation of a fixing capsule around the strands of donor and own hair is completed by uniform compaction with the fingers of the hand.

The steps are repeated for the rest of your own strands in sequence.

The final stage. At this stage, the result obtained is controlled, the client's hair extensions are cut and styled.

A new, distinguishing feature from the classic method of hair extensions using glue capsules is that the described method allows you to reduce the time of hair extensions to the client and, accordingly, the time it takes to spend in the master's chair, by preliminary preparation of donor hair strands, which consists in encapsulating them with strands before building . With pre-prepared strands of donor hair with a formed adhesive base, it is easier for the master to work with the mentioned strands, they do not get confused, as they are already fastened on one side, their tips are already completely aligned when they are in the cut, which again reduces the time for preparing donor strands, since in this case the cut is aligned on the adhesive base once, and if each strand of donor hair is encapsulated separately, then its ends will also have to be aligned separately and, with a significant amount of extension, leads to fatigue of the master and client, loss of attention by the master, deterioration in the coordination of his movements , increased muscle tone (spasticity) of both the master and the client, which additionally leads to various motor disorders and, as a result, to a deterioration in the quality of the result obtained, which can be expressed in a deterioration in the reliability of attaching a strand of donor hair to one’s own hair, increasing the visibility of attachment, highlighting insufficient or an excess of the client's own hair. In addition, in this way it is easier to adjust the size of the glue capsule and make them equal.

From 2021 to the present, the inventor has successfully used the described method when performing a hair extension procedure. Practice has shown that the described method, due to the simultaneous preparation of strands of donor hair in a section by aligning them when fixed in the hand between the index and thumb, applying a pre-melted adhesive capsule with the formation of an adhesive base on the entire section of donor hair, re-aligning and dividing the section into strands, each of which contains an adhesive base, allows you to perform an extension procedure for an average volume of hair for an average of 2 hours. When performing the procedure in the ways given in analogues, the time increases by 2 times, on average up to 4 hours. These time indicators are confirmed by practical means.

Client Evgeniya, 22 years old. A 25 cm hair extension procedure was carried out on the client’s own hair up to 10 cm long. According to the client’s response, 10 days after the procedure, donor hair does not create discomfort, there is no tension on one’s own hair, the capsule is not felt with the fingers.

Client Sonya, 27 years old. A 50 cm hair extension procedure was carried out on one's own hair up to 20 cm long. According to the client, after 3 weeks of wearing, thanks to this method of hair extension, the junctions of donor strands with one's own hair are invisible, the capsules are smaller. According to the client, hair styling is simple, the capsules are small, do not interfere with everyday styling and are not felt. Hair care has not become more complicated, only the time for drying hair after washing it has increased. He plans to carry out a procedure for hair extensions in the described way, 70-80 cm long.
