    TLDR Beta-sitosterol and stigmasterol might help prevent hair loss by blocking a specific enzyme.
    The in-silico study investigated potential inhibitors of the 5 Alpha-Reductase 1 (5AR1) enzyme, a key factor in androgenetic alopecia (AGA) or hair loss. Using homology modeling and molecular docking approaches, the study found that two natural compounds, beta-sitosterol and stigmasterol, isolated from the plant Serenoa repens, could inhibit the regular activity of 5AR1. These compounds showed strong docking affinity of -10.7 and -10.1 kcal/mol, respectively, indicating strong interactions with 5AR1. The study also identified 11 amino acid residues involved in the majority of inhibitor and 5AR1 interaction sites, suggesting these residues are essential to inhibit this protein. These findings suggest that beta-sitosterol and stigmasterol could potentially be used as safe and novel AGA medicines for hair restoration.

      Saw palmetto can help reduce DHT levels and may work in combination with other supplements like beta sitosterol and pygume, but it's less effective than finasteride. Additional treatments like pumpkin seed extract, zinc, biotin, essential oils, scalp massages, and micro-needling can support hair health, but should not replace existing treatments like finasteride.

      The regimen for hair loss includes topical finasteride, clascoterone, tretinoin, minoxidil, oral saw palmetto, beta-sitosterol, vitamin D, microneedling, and anti-fungal shampoo. Expected benefits are increased hair growth and density, with considerations for potential skin irritation and interactions between treatments.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.
