A hair implant includes: (a) a hair strand anchor including: an anchor body; at least one hair chamber disposed within the anchor body; and at least one tunnel through the anchor body, where the tunnel is free of a hair; and (b) at least one hair strand having a portion thereof retained in the at least one of the hair chamber; wherein the tunnel is configured to support collagen ligature growth after subcutaneous implantation by receiving and retaining collagen ligatures that anchor the hair implant to a hair implant recipient. Also disclosed is a hair implant including an anchor with first and second anchor bodies and at least one bridge connecting the anchor bodies and bridging at least one void between the anchor bodies, wherein the bridge supports and retains collagen ligature growth. One-piece implants are also disclosed, as are anchors, hair restoration and manufacturing methods.

The present invention relates to implantable hair which is characterized in that it is coated at least in an implantable section with a composition that comes into direct or indirect contact with the hair and contains at least one silk protein. The present invention is further concerned with methods of producing such an implantable hair and the cosmetic use thereof.

Provided is a method for efficiently culturing dermal papilla cells while maintaining an ability to induce hair follicles. A method for culturing dermal papilla cells in the presence of at least one selected from the group consisting of EMILIN and a fragment thereof.

Described herein are cellular scaffolds comprising a cell reservoir, a guide attached to the cell reservoir constructed from one or more biodegradable polymers, and a population of folliculo-genic cells. The cellular scaffolds are useful in growing hair.

Disclosed is a fiber for artificial hairs that is given a predetermined shape, the fiber being formed from a synthetic fibroin fiber containing a modified fibroin, and the fiber expanding when placed in a wet state and contracting when dried from a wet state. Also disclosed is a method for producing a fiber for artificial hairs that is given a predetermined shape, the method including retaining a fibroin fiber containing a modified fibroin in a state conforming to a predetermined shape. A wetted fibroin fiber may also be heated while being retained in a state conforming to a predetermined shape.

A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body or an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body and alternatively wherein the at least one hair strand includes a bend, wherein the at least one collagen receiving structure, or the external surface feature, is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the hair implant in the recipient. The hair implant includes a two-part construction having a base module formed of the anchor body and at least one hair stem configured for coupling with a long hair strand. Another hair implant alternative includes a hair strand having a first end that is passed through the skin, underneath and the up through the skin at another location to result in the hair strand having two portions projecting from the skin surface.

A hair implant includes: (a) a hair strand anchor including: an anchor body; at least one hair chamber disposed within the anchor body; and at least one tunnel through the anchor body, where the tunnel is free of a hair; and (b) at least one hair strand having a portion thereof retained in the at least one of the hair chamber; wherein the tunnel is configured to support collagen ligature growth after subcutaneous implantation by receiving and retaining collagen ligatures that anchor the hair implant to a hair implant recipient. Also disclosed is a hair implant including an anchor with first and second anchor bodies and at least one bridge connecting the anchor bodies and bridging at least one void between the anchor bodies, wherein the bridge supports and retains collagen ligature growth. One-piece implants are also disclosed, as are anchors, hair restoration and manufacturing methods.

The technology defined in the present document generally relates to a method for enhancing hair growth on an area of a skin of a subject. The method comprises topically applying a composition comprising at least one light-absorbing molecule to the skin; and exposing said applied composition to actinic light to cause activation of the composition. Activation of the applied composition triggers enhancement of hair growth on the skin.

The present invention provides a method for producing regenerated hair follicle primordium that allows production of regenerated hair follicle primordium more easily and in larger amounts compared to conventional production methods.

A method for producing regenerated hair follicle primordium comprising a step of obtaining hair follicle primordium by culturing a first population of cells comprising epithelial cells and a second population of cells comprising mesenchymal cells while allowing them to be in contact is provided. The production method of the present invention is characterized in that at least either one of said first population of cells and said second population of cells has formed cell aggregates before said contact, and a culture support is not used when contacting the other population of cells with said cell aggregate.

Provided are a cell-containing hydrogel body and a method of producing the same, which enable simple and effective control of the size of a boundary surface for an interaction between cells. The method of producing a cell-containing hydrogel body includes: forming, under a gas phase, a first hydrogel droplet on a surface of a substrate, the first hydrogel droplet containing first cells being dispersed therein and a first hydrogel polymer; forming, under a gas phase, a second hydrogel droplet on the surface, the second hydrogel droplet containing second cells being dispersed therein and a second hydrogel polymer, the second hydrogel droplet being combined with the first hydrogel droplet; and forming, under a gas phase, a cell-containing hydrogel body on the surface by gelling a hydrogel droplet-combined body including a first droplet portion derived from the first hydrogel droplet and a second droplet portion derived from the second hydrogel droplet.
