Hair loss

Hair loss can be divided into two basic types: permanent hair loss due to damaged hair follicles, and temporary hair loss due to short-term damage to the hair follicles. Permanent hair loss is common in male balding. In some European countries, the baldness rate for men is as high as 40%. The process of permanent hair loss (ie, male pattern hair loss) is gradually produced. At the beginning, the edge of the hair on the forehead of the head obviously shrinks, and the hair on the top of the head is scarce; then it gradually develops, and finally it will develop to the back of the head, with thin hair on both sides of the head.
