British water is hard water and contains a lot of calcium carbonate, which makes British water weakly alkaline. Weak alkaline water can be called the natural enemy of hair. People often wash their hair with weak alkaline water, so people's hair can easily become short-tempered and even lose hair seriously. Not only Britain, but also other European countries have a large number of baldness, all because the water quality in European countries is roughly the same.

cause

So far, the root cause of baldness has not been clearly determined in medicine. Now western medicine tends to think that baldness is related to the high level of androgen in human body. When the concentration of testosterone and other male hormones in human serum reaches more than 30 μ g/L, it will inhibit the growth of hair follicle cells, and the higher the concentration, the stronger the inhibition.

Due to the exuberant secretion of androgen testosterone in the body, testosterone is converted into dihydrotestosterone under the action of 5α- reductase, and then binds to androgen receptor in scalp hair follicle target cells, which inhibits the growth and development of dermal papillae, interferes with the growth and metabolism of hair follicle cells, and causes hair to enter the quiescent stage ahead of schedule, thus causing alopecia, and in severe cases, baldness.
