Pumpkin Seed Oil for Hair
A natural oil rich in nutrients that may block DHT and nourish hair follicles.
Also known as: Cucurbita Pepo Oil
Overview
Pumpkin Seed Oil (PSO) is cold-pressed from the seeds of Cucurbita pepo. It is a rich source of unsaturated fatty acids (like oleic and linoleic acid), antioxidants (carotenoids, vitamin E), and minerals (zinc, magnesium). Similar to Saw Palmetto, PSO is thought to inhibit the 5-alpha-reductase enzyme, potentially reducing DHT levels and mitigating hair loss. Its nutrient profile also helps to nourish and strengthen hair from within.
Key Benefits
Natural DHT Blocker
Phytosterols in pumpkin seed oil, particularly beta-sitosterol, are believed to inhibit 5-alpha-reductase, helping to prevent hair follicle miniaturization.
Rich in Hair-Healthy Nutrients
Provides fatty acids, zinc, and vitamin E, which are all essential for building strong, healthy hair and maintaining a healthy scalp.
Antioxidant and Anti-inflammatory
The oil's antioxidant compounds help protect hair follicles from oxidative stress and reduce scalp inflammation.
