Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

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

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

KAP-depleted hair causes less immune response and is more biocompatible for implants.

New therapies are being developed that target integrin pathways to treat various diseases.

Graphene-based hair dye is a safe, durable, and effective alternative to traditional black hair dyes.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

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

Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.

Researchers extracted tiny keratin filaments from human hair by unzipping its outer layer.

Hair damage increases significantly with higher temperatures and longer heating times.

The study found that certain conditioning compounds can penetrate hair and potentially improve its resistance to damage.
