Spontaneous Intrinsic Aging in Organ-Cultured Human Skin as a Novel Ex Vivo Assay to Test Anti-Aging Actives

Increasing the sult1a1 enzyme on the scalp may improve response to topical minoxidil. The user suggests using a baking soda solution, DMSO, and tretinoin to enhance enzyme activity and minoxidil effectiveness.

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.

Tazarotene may outperform tretinoin for hairline treatment with minoxidil, but lacks evidence. Tretinoin is recommended for the scalp, while tazarotene can be used on the face.

The conversation discusses using tretinoin for hair loss and skincare. Users share experiences, noting tretinoin's effectiveness in combination with minoxidil for hair and its proven benefits for anti-aging skincare.

The user did not respond to minoxidil and is considering using tretinoin to improve results. They also explored finasteride, microneedling, adapalene, red light therapy, and oral minoxidil as potential treatments.

Minoxidil may cause dark circles and affect collagen, and Tretinoin might help counteract these effects. Users suggest caution with Tretinoin due to potential Vitamin A toxicity and recommend using it sparingly with sunscreen and moisturizer.
