Adrenal gland disease is common in ferrets and causes hair loss and other symptoms.

African hair has the most lipids, while Caucasian hair is more hydrated and stronger.

Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.

White hair has less lipid content and absorbs water differently than brown hair.

Hair straightening changes hair structure and can cause damage if done wrong, but improvements in the methods are expected to continue.

PDI helps restore over-bleached hair's strength and structure by attaching special peptides.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

A natural steroid in the body may protect against eye damage in glaucoma.

Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.
