Topical Pumpkin Seed Oil for Hair: 5-Alpha-Reductase Blockade & Growth
The Landmark Randomized Clinical Trial on Hair Growth
In a randomized, double-blind, placebo-controlled trial published in Evidence-Based Complementary and Alternative Medicine (Cho et al.), 76 men with mild-to-moderate androgenetic alopecia were supplemented with pumpkin seed oil ($400\text{ mg}$ daily) for 24 weeks.The results astonished dermatologists:
- 40% Average Increase in Hair Count: The pumpkin seed oil group experienced a $40\%$ mean increase in hair count, compared to only $10\%$ in the placebo group, with zero adverse sexual side effects.
- Biochemical Mechanism: Phytosterols and specific polyunsaturated fatty acids block the conversion of testosterone into dihydrotestosterone (DHT) at the follicular dermal papilla level.
