Effect of pumpkin seed oil on hair growth in men with androgenetic alopecia: a randomized, double-blind, placebo-controlled trial
What it found
Hair count rose ~40% with pumpkin seed oil vs ~10% with placebo; the capsule was a proprietary multi-ingredient product, so the effect cannot be attributed to pumpkin seed oil alone.
