The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

Scientists found out how a specific protein in human hair cuticles behaves and is structured.

The cornified envelope is crucial for skin's barrier function and involves key proteins and genetic factors.

The study found that variations in hair protein genes are likely due to evolutionary deletions or duplications.

The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Biotin helps regulate proteins in the blood, which may explain its role in hair growth.

FLRG and follistatin have different roles in wound healing.

Dexamethasone affects hair growth by altering levels of proteins that either promote or inhibit hair follicle growth.

Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.
