Pumpkin Seed Oil

Reviewed by the Nimbera editorial team · Last updated May 2026

Cho et al. 2014 RCT (Evid Based Complement Alternat Med) found 400 mg/day pumpkin seed oil for 24 weeks increased hair count by 40% vs 10% in placebo in men with androgenic alopecia.$15-25/month

How to use

Take 1000 mg (1 g) pumpkin seed oil capsules daily with a meal, or use 1 tablespoon cold-pressed oil in food or smoothies. For topical use, massage a few drops directly into the scalp nightly. Consistency for at least 6 months is important.

How it works

Rich in delta-7-sterols which inhibit 5-alpha reductase and block DHT binding at follicles. Also contains zinc and phytosterols that support follicle health and reduce scalp inflammation.

Where to buy

Health food stores, natural grocers, Amazon, iHerb. Look for cold-pressed, unrefined oil. Brands: NOW Foods, Jarrow, Sports Research.

Typical cost: $15-25/month

Safety notes

Generally very well tolerated. May slightly lower blood pressure. Very high doses could theoretically interact with blood pressure medications. Choose cold-pressed to retain active phytosterols.
