HAIR LOSS
part of society. People suffering from hair loss are generally perceived as older people who are physically and socially less attractive (Goh & Zippin, 2009).
Hair loss has been for many years a common problem for dermatologists consultation. For both men and women, it is extremely important that hair is healthy, full of plenitude, movement and freshness, as it directly influences our mood and character and it can define our professional, personal and even sentimental success.
The daily loss of an average of 50 to 150 hairs is considered as normal. It is a cycle under constant renovation. The same way a person is born, grows and dies, hair follows a very similar pattern: it grows, rests and falls. The problem arises when this life cycle of hair is altered and the common problem of alopecia appears. Hair loss is caused by an alteration in the hair growth cycle, due to several factors (androgen metabolism, genetics or stress). It is characterized by changes in the ratio of anagen and telogen hair the number of hairs in the anagen phase is reduced and more hair remains in the telogen phase. Therefore, hair stops growing earlier than expected it is shorter and thinner. Some alopecias are considered as reversible because the hair cycle is disturbed but the hair follicles are still present and they follow the hair cycle even in bald scalps.
