How Pumpkin Seed Oil Helps with Hair Growth
Pumpkin seed oil is a natural 5-alpha reductase inhibitor — it blocks the conversion of testosterone to DHT, the hormone responsible for pattern hair loss. It's rich in zinc, iron, and essential fatty acids that nourish hair follicles.
🔬 What the Research Says
A 2014 randomized, double-blind, placebo-controlled trial published in Evidence-Based Complementary and Alternative Medicine found that men taking 400mg of pumpkin seed oil daily for 24 weeks had a 40% increase in hair count compared to a 10% increase in the placebo group.

📋 How to Use
Take pumpkin seed oil capsules orally. Can also apply cold-pressed pumpkin seed oil directly to the scalp as a treatment mask (leave for 30 minutes before washing). Eating pumpkin seeds also provides some benefit.
💊 Recommended Dosage
400mg pumpkin seed oil capsules daily. For topical use, apply 1 tablespoon to the scalp 1-2 times per week.
⚠️ Side Effects & Cautions
Well-tolerated. Rare GI upset. May theoretically affect hormone levels at very high doses. Consult a doctor if you have hormone-sensitive conditions.
