Different hair types in mammals are linked to variations in specific protein genes, with changes influenced by their living environments.

Permanent waving damages hair by disrupting its keratin structure.

Cysteine helps maintain keratin production in skin cells even when iron is low.

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

Human hair keratin can be used in many medical applications.

Juglone from walnut extracts may help repair damaged hair.

Bald thigh syndrome in sighthounds is caused by structural defects in hair shafts due to downregulated genes and proteins.

Using enzymes to link proteins makes hair repair treatments more effective and long-lasting.

Pal-KCV peptide strengthens hair and reduces breakage by up to 52%.

Grafted human scalp samples on mice can produce human hair, useful for studying hair genetics.

Domestic cat hair varies in thickness and length, with guard hairs being longest and thickest, and all hair types mainly contain keratin.
