Human hair has different protein structures in its cuticle and cortex.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

The Cross-section Trichometer is a new tool that can measure hair quantity and detect hair loss and growth.

Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.

The document concludes that the human keratin gene cluster is complex, with a need for updated naming to reflect over 50 functional genes important for hair and skin biology.

An elderly man with skin amyloidosis and abnormal blood proteins was monitored without finding widespread disease after 18 months.

The document explains the genetic causes and characteristics of inherited hair disorders.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.
