All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.

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

Sex steroids influence skin appendage function and neoplasm development, with changes in AR and ERalpha in certain gland neoplasms.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Wnt, Eda, and Shh pathways are crucial for different stages of sweat gland development in mice.

p63 is essential for controlling epithelial stem cells and tissue health.
