Hair Loss and Treatment
There are nearly 100 diseases that cause hair loss in literature. When we look at these diseases the most frequently seen are; male pattern (MPH), female pattern (FPH) and telogen effluvium type.
If reasons of hair loss are examined, the most encountered reasons are; hormonal imbalance, disorder of thyroid, malnutrition, use of some medicine and anemia.
Male Pattern Hair Loss (Androgenetic Alopecia)
This is the most common type of hair loss. Not just only in men but also it is common for women too. When reasons are researched two basic factors appear:
- Genetic Factor: It can similarly be seen in first or second degree relatives in family.
- Hormonal Factor: It is thought that the main reason of hair loss caused by hormones is 5-alfa reductase which transforms testosterone into dihydrotestosterone(DHT). dihydrotestosterone(DHT) shows effect by connecting to androgen receptor on hair follicles. Dihydrotestosterone(DHT) is responsible for the shortening of the hair’s life cycles. Each time these transformations occur, hair weakens more. Weak hair becomes thinner and hair loss occurs as this process is completed.
Hair development of each person is pre-determined before the birth by genetic factors. Reason of hair loss is the oversensitivity of the follicles against DHT. DHT testosterone ratio directly affects and accelerates the process.
As it can be understood from the information above, hair loss level of an individual depends on the DHT level and is not associated with the testosterone level.
This process starts with the thinning of the hair. Afterwards, the hair begins to have a fading color, hair thinning begins and finally follicles are completely destroyed.
As mentioned as a genetic factor, father’s hair characteristic do not necessarily reflect the child’s hair characteristics which means that if the father does not have any hair, it should not be concluded as the child having no hair. Hair loss possibility is a combination of both the father’s and the mother’s genes.
The hair between the neck and two ears are called permanent hair. Therefore, this region loses no hair during the lifetime.
