Studies have been published in the International Journal of Dermatologist showed that the caffeine in coffee can stimulate the growth of small follicles in the scalp in men who begin to experience hair loss, as reported by Livestrong, Wednesday (30/11/2011).
Caffeine works by blocking the effects of chemicals known to damage hair follicles. Most baldness is caused because the hair follicles (tiny sacs in the scalp where the hair grows) exposed to dihydrotestosterone (DHT) is too much.
DHT is a chemical produced by the male hormone testosterone. DHT is produced in several areas of the body, but mainly in the liver and skin (including hair). Many factors that increase the production of DHT in the body, such as stress, genetics, hormones and certain stimulants.
Hair follicles will shrink if too much DHT circulating in the blood, so the hair becomes thinner and grow into abnormal. If left unchecked, this triggers baldness on the scalp.
"Caffeine is a substance that is known, but little is known about their effect on human hair follicle growth. But this study shows a promising candidate for hair growth stimulation," explains Dr. Tobias Fischer, who conducted the study from the University of Jena in Germany.
But drinking lots of coffee may not be the best answer, because scientists estimate it took at least 60 cups of caffeine a day to reach follicles in the scalp.
Instead, researchers say it takes a topical lotion rich in caffeine that will be smeared on the scalp to block the damaging effects of DHT. Cream caffeine is expected to stimulate hair growth.
