Understanding the Reason for Hair Loss
Spurred on by the enzyme 5alpha-reductase (an enzyme located in the scalp) DHT (a hormone local) will stimulate the sebaceous glands. They are increasing their oil production will stagnate in the hair follicle, the block gradually suffocate the bulb and cause hair loss.
DHT also shortens the life cycle of the hair: stimulated by androgens, the life cycle of the hair only lasts more that 1 to 2 years (instead of approximately 4 years, hopefully).
Result: the hair fall weakened before reaching their maximum length. Each new hair is growing late, his life is shortened: the gradual evolution toward baldness. Stress also has a real impact on hair loss and is a factor that triggers or exacerbates alopecia and hair loss.
