There are many reasons for hair loss. Usually, hair loss starts from the top of the head, especially in men, and it’s known as androgenic alopecia or male type of baldness. Genetic predisposition is a common reason for it, while male sex hormones also trigger this issue. Hair follicles shrink over time, and their place is occupied by the skin. It causes hair thinning and eventually baldness. Men who have a high level of testosterone get bald early. However, the shrink follicles never die beneath the skin, and the chances of hair growth are always there if one starts taking proper diet and use a good shampoo.
