How does caffeine prevent hair loss and stimulate growth?
According to a study published by the International Journal of Dermatology, caffeine blocks out a hormone called DHT which is responsible for male pattern baldness and damage to hair follicles. In the study hair samples were taken from men and monitored in a laboratory for eight days, and it was shown that caffeine consumption had boosted hair growth 33 to 40 percent. This finding is also being applied to research regarding hair growth/loss in women.
What is the amount of caffeine you can expect per drink?
A single serving of caffeine is considered to be 100mg, roughly the amount in one cup of brewed coffee. The table below shows the estimated caffeine content for some common beverages.
|2oz||Espresso||40 to 120||mg|
|8oz||Brewed Drip Coffee||60 to 160||mg|
|8oz||Decaffeinated Coffee||3 to 5||mg|
|8oz||Green Tea||20 to 40||mg|
|8oz||Black Tea||20 to 60||mg|

Thinking of adding caffeine to your regimen?
Don't get too carried away, too much caffeine can actually boost DHT and lead to hair-loss. Just like many things with hair - the trick here is to find the balance.
