Hair loss is a physiological process that is repeated on average several times in the life of an individual. If the scalp is healthy, the physiological loss is limited: it occurs only in certain periods and the number of hair lost is not excessive. Sometimes, however, due to factors of a different nature, such as hormonal factors, stress, incorrect nutrition or drug treatments, an imbalance in the physiology of the person is created which can manifest itself with abnormal and abundant hair loss. In these cases, it is useful to act promptly with treatment programs aimed at improving the health of the hair and restoring its state of health and well-being.
