Does drinking coffee cause hair loss?

Coffee is a slightly stimulating drink. Drinking coffee has both good and bad effects on the body. Nowadays, due to various reasons, many people are experiencing hair loss. In addition to solving the problem according to the situation, they also pay attention to their daily diet, worrying that drinking coffee frequently will cause hair loss. So, does drinking coffee cause hair loss? Let’s take a look below.

The caffeine in coffee can help prevent hair loss in men to a certain extent. One of the important reasons for male hair loss is that male testosterone produces a chemical substance - dihydrotestosterone (DHT). When there is an excess of dihydrotestosterone in the blood, it will cause the hair follicles to close, resulting in slow hair growth, thus causing hair loss.

Caffeine, as a stimulant, can inhibit the destructive effect of dihydrotestosterone on hair follicles and promote the growth of hair cells. According to a German study, caffeine can block DHT, which damages hair follicles. Professor Fischer of the University of Jena in Germany, who led the study, said: "Research shows that caffeine can effectively stimulate hair growth." They placed the hair follicles of 14 men in test tubes with different concentrations of caffeine and observed them for 8 days. The results showed that the hair grew 33% to 40% faster than normal.

However, studies have shown that drinking 2 to 3 cups of coffee a day is most suitable. Drinking too much is harmful to your health. Balzac died at the age of 49 because he drank too much coffee, which put a great burden on his body! So the little caffeine in the coffee you drink every day can not inhibit hair loss at all.

How can caffeine be used to prevent hair loss?

The dosage and formula of caffeine in shampoo and hair care products are still in the trial stage. As for the effectiveness of shampoo containing caffeine, if you are interested, you can try it yourself. Some believe that if this caffeinated shampoo is left on the hair for about two minutes, the caffeine will penetrate the scalp and the effects can last up to eight days based on research.
