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

Mutant mice help researchers understand hair growth and related genetic factors.

The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

Changes in keratin make hair follicles stiffer.

South American camelids should be sheared early, fleece type affects fiber quality, and the S/P follicle ratio doesn't distinguish between Bolivian llama genotypes.

DNA methylation and long non-coding RNAs are key in controlling hair growth in Cashmere goats.

α-type filaments in guinea pig hair follicles have unique structural features.

Tissue stiffness affects hair follicle regeneration, and Twist1 is a key regulator.

New treatments for hair loss may target specific pathways and generate new hair follicles.

Overexpressing Tβ4 in goats' hair follicles increases cashmere production and hair follicle growth.

Mushroom-based scaffolds help heal skin wounds and regrow hair.

Short daily photoperiods improve cashmere production in Inner Mongolia white cashmere goats.

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

miR-133a-3p and miR-145-5p help goat hair follicle stem cells differentiate by controlling NANOG and SOX9.

Hair and wool have complex microscopic structures with microfibrils and varying cystine content.

Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

miR-218-5p helps skin and hair growth by targeting SFRP2 and activating a specific signaling pathway.

Researchers found a new gene, hacl-1, that is active in mouse hair follicles during hair growth and may be important for hair biology.
