Topical Delivery of Retinyl Ascorbate

The conversation discusses a hair loss treatment regimen including finasteride, minoxidil, micro needling, and oil blends. It questions the addition of retinol, with feedback suggesting tretinoin is more effective, while retinol may cause hair loss.

The user is seeking a substitute for Tretinoin to enhance the effectiveness of Minoxidil for hair loss. They are considering using Retinol as an alternative.

Tretinoin and microneedling both enhance hair growth through different mechanisms, with microneedling being considered safe for long-term use. Optimal microneedling needle length varies, but 0.8 mm is suggested for hair growth, and a Dermastamp is recommended to avoid skin damage.

Topical retinol does not affect hair loss and may help hair regrowth. It is different from isotretinoin, which can cause hair loss due to its systemic effects.

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.

Tretinoin can increase hair follicles and is used alongside minoxidil and finasteride for hair growth, though it may cause skin peeling. Users report varying results, with some experiencing regrowth and others questioning its efficacy for hair.
