Effects of All-Trans Retinoic Acid on Goat Dermal Papilla Cells Cultured In Vitro

Verteporfin followed by retinoic acid improves wound regeneration in mini-pigs. Retinoic acid does not significantly enhance regeneration in rabbits.

Tazarotene may be more effective than tretinoin when combined with topical minoxidil for hair loss due to its selective binding to RAR-beta and gamma, though it can cause irritation. Tazarotene's potency can lead to indirect inflammatory reactions despite potentially causing less irritation than tretinoin.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

Using retinol with minoxidil may not be as effective as tretinoin, but retinaldehyde or adapalene could be alternatives. A micro-roller with minoxidil is suggested for better results.
