Can caffeine stimulate hair follicle growth?

In a new study, scientists have found that caffeine blocks a chemical that damages hair follicles, but does not recommend drinking large amounts of coffee to treat hair loss because they estimate that it takes up to 60 cups of coffee a day to have a significant effect on hair follicles. But a German cosmetics company has developed a caffeine-rich solution that can be applied to the scalp.

"although caffeine is a well-known substance, we know very little about its effect on human hair follicle growth, and this study shows that it is effective in stimulating hair follicle growth," the researchers said. "

Most people lose their hair because the hair follicles that grow their hair are exposed to the male hormone dihydrotestosterone. When the blood contains a large amount of dihydrotestosterone, the hair follicles contract, resulting in thinner hair and shorter lifespan.
