Caffeine from coffee has been proven to be a wonder substance in the field of skin care. Presently, the cosmetic industry raves about skin care products containing caffeine as an ingredient. Taking caffeine to the next level could result to coffee mixed in hair products and shampoo.
Recently, there are indeed studies already published in the International Journal of Dermatology (Volume 46, Issue 1, pages 27-35) discussing coffee hair growth benefits as a possible stimulant for hair follicles. According to the study, caffeine works by blocking the effects of a chemical known as DHT which stands for Dihydrotestosterone (5α-Dihydrotestosterone) that damages hair follicles and is thought to cause Male Pattern Baldness (MPB).

Dr. Tobias Fischer of the University of Jena in Germany studied the effect of caffeine on human hair follicle growth and discovered that caffeine shows a promising effect on hair growth stimulation. He took scalp biopsies from men in the early stages of hair loss and extracted hair follicles from the 14 men in the trial and placed them in test tubes with solutions containing different levels of caffeine. The hair samples were left in the lab for up to 8 days to monitor the growth results.
Results from Dr. Fischer’s studies showed that the average growth of the follicles treated with caffeine increased by around 46 % compared to the control group and the life cycle of the hair treated with caffeine was extended by 37 %. Caffeine improved the length of the hairs by 33% - 40%. Dr Fischer noted that “hair follicles treated with caffeine showed a highly significant growth rate at 24 hours and still showed further significant growth at eight days.”
