The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Polygonum multiflorum extract helps grow hair by activating certain hair growth signals in mice.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Cetuximab can cause excessive eyelash growth.

After menopause, women lose a lot of skin collagen, but estrogen replacement might improve skin health.

Human hair follicles can regenerate after removal, but with low success rate.

Trichoscopy is a quick, noninvasive method to diagnose hair and scalp disorders, often reducing the need for biopsies.
