The Claim
Supplementation with pumpkin seed oil at a dosage of 400 mg per day for 24 weeks has no statistically significant effect on serum free testosterone levels in men diagnosed with androgenetic alopecia.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking pumpkin seed oil pills every day for 6 months doesn't change the level of testosterone in the blood of men who are losing their hair due to genetics. So, if it helps their hair, it's probably not because it's affecting their hormones.
See the scientific wording
Pumpkin seed oil supplementation at 400 mg/day for 24 weeks does not significantly alter serum free testosterone levels in men with androgenetic alopecia, suggesting its effect on hair growth may not be mediated through systemic androgen modulation.
What the research says
1 studyThe study found that pumpkin seed oil helped men grow more hair without causing side effects, and since it didn’t change hormone levels (though they didn’t measure them), it probably works directly on the scalp instead of through the bloodstream.
