1. Hormonal changes
Hormonal imbalance results in a wide range of health and beauty problems. In most cases, hair loss in women occurs after childbirth and even during menopause. On the other hand, hair loss in men occurs when their hormonal changes as they age. In either case, the hair loss is a result of the dihydrotestosterone (DHT) response by the hair follicles. The hair growth cycle is regulated mainly by hormones. In women, estrogen hormones play a crucial role in enabling their hair to grow in size, whereas men androgen hormones also play a part in hair growth. Too many of these hormones lead to hair loss.
