The Claim

Oral administration of pumpkin seed oil at a dosage of 400 mg per day for 24 weeks does not significantly increase hair thickness in men with androgenetic alopecia, despite a statistically significant increase in total hair count, suggesting that the intervention promotes the growth of new hairs rather than thickening existing ones.

How it works
1 study reviewed
In plain English

Taking pumpkin seed oil pills every day for 6 months doesn't make your existing hairs thicker, but it might help you grow more hairs overall — so you look fuller, not coarser.

Pumpkin seed oil at 400 mg/day for 24 weeks does not significantly improve hair thickness in men with androgenetic alopecia, despite increasing hair count, indicating it promotes new hair growth rather than thickening existing hairs.
