Study: The caffeine in coffee stimulates hair growth and prevents hair loss

The obstacles to solving hair loss can seem overwhelming. But it is surprising to know that the method of treatment may be simpler than expected.

It is known that there are many environmental and genetic factors that combine to cause hair loss. However, research has found that some ingredients block the mechanisms that cause hair loss. Caffeine is perhaps the most surprising.

To understand how caffeine prevents hair loss and even promotes hair growth, it is helpful to consider the sequence of events that cause androgenetic alopecia.

Alopecia is a permanent type of hair loss that usually occurs due to genetic and environmental factors.

In androgenic alopecia, hair loss usually occurs when the hormone dihydrotestosterone (DHT), or male hormone, damages hair follicles.

Women with too much DHT can experience hair loss.

Damage to hair follicles occurs gradually, which eventually leads to baldness.

But according to research, the caffeine in coffee can help stimulate hair growth and stop hair loss.

One laboratory study found that caffeine helps block the effects of the male hormone on male hair follicles.

Caffeine stimulates the elongation of the hair shaft, which leads to longer and wider hair roots. It also prolongs the period of growth which is the stage of hair growth.

The study also tested the effects of caffeine on female hair follicles and found that it has a growth-promoting effect on female hair follicles as well.
