A Composite Model for the Transport of Hydrophilic and Lipophilic Compounds Across the Skin: Steady-State Behavior

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.

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.

The conversation is about the effectiveness of 0.25% topical finasteride compared to other concentrations and forms. Users discuss its potential for better scalp DHT reduction and fewer side effects, with some preferring topical over oral treatments.

A user is concerned about the best method to apply Minoxidil for hair loss, noting conflicting advice from doctors. Another user mentions that not massaging the liquid can cause it to drip, suggesting slight spreading with fingers.
