Dr Adolf Klenk, who is a leading international expert on hair loss, recently visited South Africa to promote his discovery that caffeine stimulates hair growth. Here is an interview he gave there:

An employee of a German "cosmeceutical" company, the Dr Wolff Group, he discovered that caffeine protected hair roots against hereditary and menopausal hair loss in men and women; and it also facilitates growth. Based on this discovery the Wolff group now produces caffeine-based shampoos for men and women. 

Up to 70 percent of men suffer from male pattern baldness (MPB). Hair loss is one of the things men dread most about getting older. (The other great fear is impotence.)

To most men a full head of hair is a sign of health, youthfulness and virility, and the first signs of hair loss along the sides of the forehead and on the crown of the head can cause strong reactions like depression, social withdrawal, even loss of self-esteem.
  
Women are affected by hair loss to a much lesser degree than men, but it can lead to similar problems like depression and loss of self-confidence.  

A study by the Institute for Dermatology at Lübeck University which was published in the British Journal of Dermatology found that caffeine promotes hair follicle growth by influencing important proteins that regulate cell growth.

More specifically, caffeine counteracts the growth inhibitory effect of testosterone (the “male” hormone) on cyclic adenosine triphosphate (cATP), which provides the energy necessary to keep hair roots healthy and to stimulate growth. Interestingly, this only happens in the scalp, not in any part of the body.

We'll do our own testing with CaffeinAll™, by adding it to a shampoo base. Stay tuned!
