This is a very impressive study on 76 men which took place over 24 weeks and got substantial growth. Mean hair count increases of 40% were observed in PSO-treated men at ‘just’ 24 weeks, whereas increases of 10% were observed in placebo-treated men (P < 0.001). Adverse effects were not different in the two groups. I think that this is worth a try for many men thinking about doing something simple and inexpensive for treating their hair loss.
