Pumpkin seed oil is the only naturally sourced DHT-blocking ingredient with a published RCT specifically for androgenetic alopecia. But beta-sitosterol — the active compound — is extraction-method-sensitive, and most commercial pumpkin seed oils are not cold-pressed.
The Clinical Evidence
Cho et al. (2014, EBCAM): 76 male androgenetic alopecia patients. Randomised, double-blind, placebo-controlled. 400mg cold-pressed pumpkin seed oil vs placebo, 24 weeks. Hair count increase: 40% (pumpkin seed) vs 10% (placebo). No significant adverse effects.
Why Cold-Pressed Is the Only Acceptable Extraction
Cold-pressed Cucurbita Pepo: 100–140mg beta-sitosterol per 100g oil
Expeller-pressed at 80–100°C: 50–80mg (30–50% reduction)
The 2014 trial used cold-pressed pumpkin seed. Vihira 360° uses cold-pressed Cucurbita Pepo Seed Oil to match this standard.
Frequently Asked Questions
How long until I see results?
Most users notice reduced shedding within 2–4 weeks. Visible density and growth improvements take 3–6 months, following the natural hair growth cycle.
Is Vihira 360° greasy or heavy?
No. The ultra-lightweight Caprylic/Capric Triglyceride base absorbs rapidly into the scalp without heavy residue. Designed for Indian scalps and climate.
Should I eat pumpkin seeds or apply pumpkin seed oil for hair fall?
Both. The 2014 RCT used oral supplementation. Eating 30–40g raw pumpkin seeds daily provides beta-sitosterol systemically. Vihira 360° provides topical delivery directly to follicles. The routes are complementary.
