Excessive Sweating Can Cause Hair Loss!
Damaged hair caused by excessive sweating
Its been said that in US, one of the most common causes of hair loss that goes undetected is excessive sweating--known as hyperhydrosis.
According to trichologist Erkkie Harris-Wells the founder of Miyohara International Trichology Clinic, who diagnoses and treats hair and scalp problems: "Excessive sweating can be harmful to the hair and scalp because of the lactic acid in our sweat secretions."
The more scientific explanation is that the lactic acid produced by sweat glands strips away the epithelial sheath, which is the outer protective layer of the hair. As a result, hair loses volume and density, and it becomes porous and dry to the point of brittleness.
"Hyperhydrosis accounts for about 70 percent of hair loss cases for both males and females. While European physicians are accustomed to this type of diagnosis, most American doctors are unaware of the link between hyperhydrosis and hair damage. It can't be treated with a drug like Rogaine. I'm even writing an article to alert hair transplant surgeons to the ways in which hyperhydrosis can compromise their restoration procedures.", further explained by Erkkie.
It was also stated that the excess acid can also cause inflammation of the scalp, and if untreated can produce red, sore pustules that will become infected with bacteria.
