Melatonin Treatment For Baldness
Melatonin is a hormone secreted by the pineal gland. This hormone has been produced and marketed in pill form to help regulate sleep-wake cycles in patients with temporary sleep pattern problems.
From January to April 2003 a double-blind, placebo-controlled cross-over study was conducted at the Forenap Centre Hospitalier in Rouffach, France on eight healthy women to assess the clinical and biological tolerability of cosmetic melatonin. One group of this study were applied with a 0.0033% cosmetic melatonin solution once daily on their scalp each night before bedtime, while another group were treated with a placebo solution following the same protocol as the other group.
Within the duration of the study, all the participants were monitored every 14 days for any abnormal increase or decrease in their blood pressure and heart rate as well as any observable increase or decrease in their endogenous melatonin secretions. Based on the results of the electrocardiogram readings collected from all of the participants at the end of this study, showed no significant increase in blood pressure and heart rate for all the participants. But according to clinical laboratory tests for serum melatonin levels done on all participants, it was observed that a gradual increase in blood serum melatonin levels, which was vital for hair growth and restoration, was noted on the participants who were treated with the cosmetic melatonin solution.
