Definitions

  • the present disclosure relates to hair extensions, and more specifically, to a hair extension assembly in which one or more hair extensions, each comprising a plurality of hair strands, are secured to a hair extension connector that is movably coupled to a hair fastener.
  • Hair extensions are a well known and popular product for increasing the length and/or fullness of a person's hair while blending in and integrating with the hair of the wearer. Extensions allow the wearer to tailor the appearance of their hair by typically adding multiple extensions with selected length(s) and color(s) to achieve a desired look.
  • Known hair extensions can be weaved, glued/adhered, clipped onto or crimped into a wearer's actual hair. Hair extensions may comprise a group of hair extension strands that are glued at one end to form a tip.
  • One long-lasting technique of applying hair extensions involves threading a section of a person's actual hair through a deformable fastening ring, placing the tip of a hair extension into the fastening ring and then crimping the ring, thereby fixedly securing both the hair extension strands and the person's actual hair within the crimped ring.
  • Crimped hair extensions provide a secure and integrated engagement with the wearer's actual hair that can comfortably withstand an active lifestyle, hair brushing, hair shampooing and sleeping. Once applied, the extensions can be worn for as many as one to three months.
  • the process of applying the extensions may involve the use of many dozens of hair extensions and fastening rings in order to give the wearer's hair a full, natural and symmetrical appearance. This is a time-consuming and costly process involving the repetitive handling of multiple components such as the small fastening rings, the hair extension and the crimping tool.
  • the number of fastening rings is generally determined by the style desired and the amount of fullness and length to be added to the wearer's actual hair.
  • crimping provides a secure engagement with less scalp and hair contact with glue/adhesives than other techniques involving direct glue/adhesive application
  • the foregoing crimping technique does require the wearer's actual hair to be crimped tightly against the glue used to form the tip of the hair extension, which glue can damage the actual hair over time.
  • the wearer's actual hair strands may become integrated into the glue due to the pressure of the crimp and the movement of the hair against the glue during the course of wearing the hair extension in natural activities such as sleeping. Removal of the hair extension thus may also cause tugging of the actual hair or even loss of strands of actual hair.
  • Hair extension techniques which can damage or pull out a wearer's actual hair are particularly not desirable by those with thin or thinning hair.
  • a multi-extension apparatus that comprises an elongated weft of fabric with hair extension strands sewn into the weft along the weft's length.
  • a plurality of connecting rings are sewn to the weft in fixed locations at spaced intervals along the length of the weft.
  • the weft is placed immediately adjacent the scalp; a section of the wearer's actual hair is threaded through the first connecting ring and crimped; and then specific sections of the wearer's actual hair corresponding to the locations of the fixed connecting rings must be sequentially grasped from behind the weft and threaded through the connecting rings and crimped. Additional multi-extension weft apparatuses and/or other hair extensions are then applied to the wearer's head to achieve the desired appearance.
  • wefts are not generally recommended for thin hair and/or light hair with specific style requests (such as where the weft would be noticeable under the hair or would add too much bulk and weight); wefts are also not generally suitable for applications where variability in color, length and/or style of hair extension strands is desired. Wefts, e.g., can add weight, bulk, rigidity, discomfort and make shampooing of the hair and scalp more difficult than the prior art application of crimping a single hair extension.
  • the weft adds the bulk of the weft material and the bulk of the excess hair which is folded over for the purpose of sewing the hair to the weft.
  • the application of the weft also requires specific sections of hair in precise locations behind the weft to be grasped for threading based on the close attachment of the weft against the scalp and the fixed relationship of the location of its connecting rings.
  • a hair extension assembly which comprises at least one hair extension comprising a plurality of hair strands, wherein the at least one hair extension has a first end.
  • the assembly further comprises a hair fastener having a length defining a length axis and also comprises at least one hair extension connector.
  • the at least one hair extension first end is connected to the at least one hair extension connector, and the hair extension connector is connected to the hair fastener.
  • the entire length of the at least one hair extension is movable from a first orientation parallel to the hair fastener length axis to a second orientation parallel to the hair fastener length axis.
  • the feature that the entire length of the at least one hair extension is movable from a first orientation parallel to the hair fastener length axis to a second orientation parallel to the hair fastener length axis is merely optional and not necessary.
  • the at least one hair extension connector has a cross-sectional area, and the cross-sectional area of the first end of the at least one hair extension is greater than the cross-sectional area of the at least one hair extension connector.
  • this optional feature is not necessary compared to the third aspect of the disclosure described below.
  • a hair extension assembly which comprises a single hair fastener and a plurality of hair extensions connected to the single hair fastener.
  • Each hair extension in the plurality of hair extensions has a first end and a second end, and each hair extension first end is connected to the single hair fastener and selectively movable with respect to the single hair fastener.
  • the entire length of the at least one hair extension is movable from a first orientation parallel to the hair fastener length axis to a second orientation parallel to the hair fastener length axis.

Different lengths, styles, colors and materials can be combined to create a style customizable for the wearer. Because different lengths, styles, colors and materials can be selected for different attachment locations, the stylist or wearer can customize the look as desired. In certain implementations, the hair strands are pre-treated with a material that enhances the softness of its texture.
  • Hair fastener 30 is generally annular and includes a through-opening 36 along its length (in the z-axis direction). Although the length/diameter ratio of fastener 30 appears to be greater than 1 in the figure, no particular ratio is required. In addition, hair fasteners having shapes other than annular may be used. However, hair fastener 30 is preferably configured for attachment to a wearer's actual hair.

For example, in many known configurations, the amount of hair extension strands that can be connected to a given hair fastener is limited because the ring must accommodate the wearer's actual hair and all of the hair extension strands being applied within the opening of the fastener. However, as shown in FIG. 1 , hair extension assembly 20 readily accommodates a greater amount of hair extension strands including multiple hair extensions. Hair extension assembly 20 allows a wearer to attach more hair extension strands in less space and with fewer rings. The fewer number of rings, along with the pre-assembly of the pieces, makes application easier.
  • Comfort is also enhanced by the reduction in the number of required rings (and other material used to achieve the attachment of the hair extension strands).
  • a reduction in the number of attachments and/or smaller size of the fasteners provides an integrated and natural appearance, which is especially beneficial for people with thinner hair where the excessive numbers of rings tended to be needed to achieve the desired fullness or style can lead to discomfort and an unattractive visibility of the hair extension ring.
  • the ability to reduce the number of hair fasteners 30 also can be less damaging to the hair. The lack of adhesive or glue in close contact with the wearer's actual hair provides a substantial benefit.
  • hair extensions 22 and 24 are connected to hair fastener 30 via hair extension connectors 32, 34 the hair extensions 22 and 24 may be more readily re-used than with many conventional hair extensions because the hair extensions 22, 24 are not crimped in hair fasteners 30. As a result, the extensions 22, 24 can readily be separated from hair extension assembly 20 for subsequent re-use, such as by cutting hair extension connectors 32 and 34.
