DYNAMIC mechanical measurements on α-keratin in water 1 have recently indicated that the matrix—which becomes swollen in water—behaves like a polymer with an effective glass transition ...

This was surprising because α-keratin is present in only small amounts in modern feathers. In addition to co-expressing both keratin proteins, the Anchiornis feathers had already undergone the ...

Modern vertebrates that walk on land have the protein called keratin. Alpha-keratins (α-keratins) are in the 10 nanometer-wide filaments of the hair, skin, and nails of humans and other mammals.

The protein α-keratin is found in hair, skin and nails. The polypeptides which make up α-keratin is shaped as a helix, and four of these coil together to form a protofibril. The protofibrils ...

Keratherapy, led by owner and CEO MJ Irani, redefines keratin haircare with KERABOND™ tech, offering lasting strength, shine, and sustainability for all hair types without compromising health.

Collagen supports hair structure and scalp health, while keratin repairs hair strands and enhances hair smoothness and shine.

“The skin comprises patches of desquamating epidermal corneocytes that preserve a cytoskeletal array of helically coiled α-keratin tonofibrils. “This structure confirms that basal birds and ...
