Mental health: The tryptophan in pumpkin seed oil may improve sleep and mood as it can be converted into serotonin, a hormone that promotes good sleep and well-being.

Does it actually increase hair growth?

Hair oils can add in fatty acids to your hair to replace lipids (fats, oils, waxes, and vitamins that make up the hairs’ structure). That then can helpprevent split ends and breakage. It's also important to note that they may interact with certain medications, so it's always best to consult a healthcare provider before starting any new supplement regimen. Pumpkin Seed Oil: Who should use it: In general, anyone experiencing thinning hair. Saw palmetto can provide benefits across all hair types, as it promotes scalp health. Pregnant and breastfeeding women should avoid saw palmetto. Some studies suggest that pumpkin seed oil might inhibit an enzyme known as 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone associated with hair loss in both men and women.

BPH is part of a larger group of lower urinary tract symptoms (LUTS), a group of symptoms typically involving the bladder, urethra, and prostate. Unlike BPH, LUTS can affect both men and women ( 4, 5). A small RCT evaluated the efficacy of an oral tablet containing 200 mg of SP extract and an extra 50 mg of β-sitosterol (which has also been studied singularly for its antiandrogenic effects) versus placebo, taken twice daily in 26 men with mild to moderate AGA over 25 weeks. The primary endpoints of hair loss arrest and qualitative hair improvement were assessed objectively by researchers and subjectively by study participants via a standardized 7-point scale questionnaire. SP demonstrated 60% “improvement” in hair loss arrest and overall quality versus 11% among placebo. The active tablet also showed greater conservation of hair density and quality over time, as subjectively assessed by the study participants [ 19]. However, more research is needed to fully understand their effects on hair health. Consult a healthcare provider before starting a new supplement regimen. Anti-inflammatory properties: Some research indicates that saw palmetto has anti-inflammatory properties, which may help reduce inflammation in the body. The researchers concluded that the saw palmetto group experienced a distinct increase in hair growth. When compared with the finasteride group, those treated with saw palmetto didn’t have spectacular results. Another difference between the two was the fact that finasteride acted both in the front area and the vertex while saw palmetto acted mostly in the vertex.Improved hair pull test at 1,3, and 6 mo (9.8, 7.5, and 6.5%, respectively) for SP versus placebo (11.9, 10.7, and 8.8%, respectively) Murugusundram S.
