Dutasteride 0.5 mg in men outgrew finasteride 1 mg on hair count and width in a randomized trial. The HairMax Lasercomb raised terminal hair density versus sham across four trials, and a 655 nm laser comb improved hair in 28 of 32 patients. Half-head PRP injections added hairs versus placebo; year-long PRP injections raised density, and PRP in nonresponders lifted hair count from 71 to 93 units. Pumpkin seed oil 400 mg daily raised hair counts 40% versus 10% on placebo. Finasteride in hairy Japanese patients worked in 88.9% versus 31.6% of others.
