New treatments for skin and hair repair show promise, but further improvements are needed.

Superficial granulomatous pyoderma is a unique, mild form of skin disease that often heals without strong medication and responds well to milder treatments.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Effective repair of bad hair transplants requires skilled techniques and careful use of donor hair, with strategies like reimplantation and camouflage, and new methods to minimize scarring.

Finasteride improves immune response and reduces organ damage after trauma hemorrhage in mice.

The best results in surgical hair restoration come from careful techniques, optimal use of limited hair supply, correct hair direction, saving hair for key areas, understanding scarring effects, and adjusting hair graft density.

AKN is a chronic scalp condition in African-descended males, treated with topicals, antibiotics, steroids, and sometimes surgery or laser.

Bead-jet printing of stem cells improves muscle and hair regeneration.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.
