Evidence Review: Natural Hair Supplements: Biotin and Collagen

The user has been using 1mg finasteride and biotin-collagen supplements for 5 months, noticing some progress in hair regrowth. They also use various oils and shampoos, plan to start oral minoxidil, and seek advice on improving their hair care routine.

OP uses multivitamins, collagen, biotin, keratin, omega-3, satin bonnet, dandruff shampoo, oil moisturizer, and sun exposure for hair care. Users suggest adding antioxidants, probiotics, pumpkin seed oil, vitamin D, iron, and dermastamping.

Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.

A woman found that taking grass-fed collagen powder helped with her alopecia, leading to hair regrowth and reduced hair loss. She initially took it for gut issues, not hair, and also noticed improvements in arthritis and reduced bruising.

Biotin may strengthen existing hair and reduce hair loss, but it doesn't promote new hair growth. Some users report stronger, darker hair, while others see no benefits or experience acne.

User experienced hair regrowth and no side effects after 10 weeks on 0.25mg finasteride daily, along with biotin, collagen, micro-needling, and hair oil. They stopped minoxidil due to inconvenience and noticed initial shedding but now see more fullness.
