Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.

Keratin 15 expression in skin cells is regulated by two mechanisms involving PKC/AP-1 and FOXM1.

The study concluded that PKP1 is essential for skin integrity and hair growth, and its dysfunction causes the symptoms of ectodermal dysplasia/skin fragility syndrome.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Marine mammals lost many α-keratin genes, aiding their adaptation to aquatic life by becoming hairless.

Changthangi goats have specific genes that help produce Pashmina wool.

A rare gene variant causes hair and nail issues in a family.

Telogen is an active phase with important biological processes, not a resting phase.

Bleaching hair damages protein structure, especially keratin, leading to weakened hair.

The research identified genes and pathways important for sheep wool growth and shedding.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

Keratin gene clusters in humans and marsupials are similarly organized.

Fine wool sheep have more genes for wool quality, while coarse wool sheep have more for skin and muscle traits.

Keratins are crucial for hair strength, and mutations in certain keratin genes cause hair disorders.

Hair in mammals likely evolved from glandular structures, not scales.

Ferulic acid helps wounds heal faster by reducing inflammation and promoting skin cell movement.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Abnormal keratin expression in mice causes severe oral issues, affecting feeding.

Keratin mutations may cause scarring alopecia by damaging hair structure.

Recombinant keratin K31 makes damaged hair thicker, stronger, and straighter.

Melatonin treatment increases a specific RNA in goat cells that boosts cashmere growth.

Sheep and goat hair fibers are complex due to keratin-associated proteins, which are important for fiber properties and growth.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

Human hair-derived particles can effectively carry and release the cancer drug Paclitaxel in a pH-sensitive manner, potentially targeting cancer cells while sparing healthy ones.

K42 and K124 keratins are only found in horse hoof lamellae.

The study found genetic differences related to hair development that may explain hair loss in a patient with Trichorhinophalangeal syndrome type I.

Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.

Certain treatments can increase protein binding to natural hair but are less effective on permed hair.

Hard α-keratin has a universal molecular structure with a specific superlattice arrangement.
