Differential Activity of 2-Methylene-19-Nor Vitamin D Analogs on Growth Factor Gene Expression in Rhino Mouse Skin and Comparison to All-Trans Retinoic Acid

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.

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.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

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.

Vitamin D supplementation may have led to slight hair regrowth and density improvement. Other treatments discussed include finasteride, minoxidil, and maintaining optimal vitamin D levels.

A participant using Veradermics VDPHL01, an extended-release oral minoxidil, experienced significant hair regrowth from Norwood 6 to Norwood 3V without side effects. They plan to use dutasteride after the treatment to maintain results.
