TLDR 5% minoxidil works better for hair growth and density, with minor irritation.
This study compared the effectiveness of 5% topical minoxidil, 2% topical minoxidil, and a placebo in treating androgenetic alopecia (AGA) in men. The study involved 393 men and lasted for 48 weeks. The results showed that 5% topical minoxidil was significantly more effective than the other two treatments in promoting hair growth and improving hair density. The study also found that 5% topical minoxidil was well-tolerated and had no serious side effects. However, local irritation was more common with 5% topical minoxidil.
