Biotin

Long-Term Outcomes

Long-term update summary:\n1. Hair growth improved when Biotin was combined with Zinc, Vitamin C, Vitamin B12, and topical Castor Oil for roughly three weeks. Hair appeared thicker.\n2. Castor Oil did not seem to work nearly as well unless Biotin was also taken internally.\n3. Around 40,000 mcg produced excellent hair growth, increased tissue fullness, reduced forearm wrinkling, and no heart problems, but also caused fluid retention and enlargement of genital tissue.\n4. Around 30,000 mcg gave the best overall balance, with strong hair growth and less fluid retention than 40,000 mcg.\n5. Around 20,000 mcg produced milder hair-growth effects and no enlargement was observed.\n6. Vitamin B12 appeared necessary for maximum tissue fullness; eyesight also improved after adding B12. Without B12, eyesight became blurry.\n7. Vitamin B1 seemed to reduce the positive effects of both Vitamin B12 and Biotin, including less tissue fullness and reduced warmth.\n8. Topical Biotin only made hair softer and seemed to reduce the effectiveness of topical Castor Oil, so I would not continue using it topically.\n9. Current opinion: Biotin remains one of my preferred supplements for hair growth, with best results when combined with Vitamin B12, topical Castor Oil, and Minoxidil. Higher doses seem stronger but may bring more side effects.
