If a man starts noticing an intensive hair loss and baldness, he begins to look for a cause. Is this genetics, or a bad influence of the ecology? Or is this stress or a bad diet? All these factors, of course, may cause the hair loss but the alopecia is related to another cause in most men – a high level of dihydrotestosterone.
Several important facts about dihydrotestosterone:
- It is the strongest androgenic hormone in the male body, and it is more active than testosterone.
- According to the data of the scientists and doctors trichologists, 96% of all cases of alopecia in men are caused by the negative influence of this hormone.
- Women also have dihydrotestosterone in the body but it does not cause alopecia.
Dihydrotestosterone hormone is a biologically active type of testosterone formed out of it in the cells of the target organs under the influence of the 5alpha-reductase enzyme. About 90% of testosterone is inactive in the blood plasma. Testosterone is not very active because of its poor androgenic activity and a high anabolic activity. So, dihydrotestosterone is responsible for the formation of the sexual characters and a work of the endocrine function.
DHT is responsible for the processes happening at teenagers during adolescence and turning them into a mature man. It also influences on the formation of the genitals, erection, and libido.
According to the results of the clinical studies, a great amount of the DHT is concentrated in the genitals and hair follicles. Due to this the increased content of this hormone, the hair follicles are damaged.
How does dihydrotestosterone influence on the hair loss?
If we take pincers and pull a hair with root, a lot of dihydrotestosterone may be found during the examination of the hair follicle composition. This hormone is responsible for the production of hair, and its existence does not mean that you will lose hair soon.
It is very important how active dihydrotestosterone is and in what amount it is concentrated in the hair follicles. If the excessive amount of the androgenic hormone is accumulated there, a process of the follicle dystrophy begins gradually. Due to the accumulation of the hormones, a nutrition of the hair follicle is affected, so that it is reduced in size. In some period of time, hair is thinned, becomes weak and short, and loses color. After the complete termination of the hair follicle nutrition, the hair is lost, and a man has baldness during the active process.
Then the follicle is covered with the connective tissue, and it may cause a nonreversible alopecia. Therefore, it is necessary to go to a doctor and take the blood test during the hair loss. It will be clear during the first medical examination that the hormone level is high and the treatment should be started.
This type of the alopecia is called as an androgenic alopecia in the medical practice.
Who is more subject to the hair loss?
All men have DHT in the body in a great amount but not all of them have alopecia. Moreover, this process may start at 18 and last till 50, and some men go bald in 3-4 years.
This process is explained because every man has a different sensitivity to the androgenic hormones. A high sensitivity of the hair follicles to the DHT plays a great role in the development of alopecia.
A sensitivity is transferred genetically via parental linage. Even if your grandpa has the androgenic type of the alopecia, you have a high sensitivity of the hair follicles to dihydrotestosterone in 70%, and it is necessary to control the hair loss and take medical examinations. The gene is transferred in 2-3 generations, and so if your dad has beautiful and healthy hair, it does not mean that you will have it as well. However, nowadays, the androgenic alopecia is successfully treated. There are even methods to prevent alopecia, if one goes to a doctor in time.
