Researchers from the Republic of Korea's Pusan National University have confirmed that pumpkin seed oil increases hair growth among balding men.
The medical researchers tested the pumpkin seed oil on 76 male patients with moderate androgenic alopecia – male pattern hair loss. None of the patients had tried any previous medication, supplement or topical therapy for at least three months prior to the beginning of the study. The researchers recruited 90 patients, but excluded those with high liver enzyme levels.
The patients were divided into two groups and half were given a placebo. The treatment consisted of giving the patients 400 milligrams of the pumpkin seed oil per day in capsules. They were given two capsules before breakfast and two capsules before dinner.
After three months and at the end of the study at six months the patients were assessed using blinded practitioner analysis, and given a point score, which ranged from -3 (greatly decreased) to +3 (greatly increased).
