Nanomaterials can improve hair care products and treatments, including hair loss and alopecia, by enhancing stability and safety, and allowing controlled release of compounds, but their safety in cosmetics needs more understanding.

Different fields of expertise must work together to better understand hair growth and create effective hair loss treatments.

Transglutaminase activity is important for skin and is found in both mammals and birds.

Mice with extra human KLK14 had hair and skin problems, including weaker cell bonds and inflammation, linked to Netherton syndrome.

Hair proteins in preschool children and their mothers could indicate developmental changes and health status.

Androgens promote beard growth but cause hair loss in androgenetic alopecia, with TGF-β1 as a potential treatment target.

The model helps understand and improve treatments for alopecia areata by simulating hair growth and immune cell interactions.
