ABOUT HAIR LOSS
History of Hair
Hair loss is not a new problem for man. It is tried to be prevented throughout the history in many societies from ancient Egypt, to France. It affected people since their existence, and people tried every way to get a solution. In the last century, hair loss became an important cosmetic problem both for men and women.
Hair Loss Patterns
Common Hair Loss
The hair that finished its lifespan will fall off naturally or by external factors like combing, washing, styling. New hair will grow instead of them. Experts say that 100 to 150 falling hair per day is normal.
Temporary Hair Loss
Hair loss occurs for many reasons. Without identifying the reason, you cannot treat it right. Therefore, knowing the true cause of the hair loss is vitally important. Hair loss can occur both in men and women. It can be treated with the right and effective treatments as long as it is not caused by genetics or by a chronic disease. Some example reasons of the temporary hair loss are pregnancy, external factors, air pollution, seasonal conditions, tiredness, stress, unhealthy eating habits, improper hair care, harmful chemicals in hair cosmetics. All those reasons can be controlled, and the hair loss can be treated.
Genetic Hair Loss
Genetic hair loss can occur when a family member like mother, father, uncle etc. , has the same condition. Research has shown that among ten men, nine have genetic hair loss, and among ten women, six have genetic hair loss. It usually occurs after puberty, in the 20s or 30s, and starts from the forehead hairline, then continues with the top of the head. Its most common names are androgenetic alopecia, male pattern alopecia, and common baldness. It can affect all of the head, but usually, it does not effect nape of the neck and temporals. Androgenetic alopecia occurs in women, too, but in a different pattern. The gene or genes that are responsible from androgenetic alopecia by themselves alone, cannot be discovered yet. But scientists suspect that these genes play a role in the synthesis of male hormones, 5-Alfa reductase enzyme, and the androgen receptors in the hair roots. These are thought to be the most important factors in male pattern hair loss. 5-Alfa reductase enzyme turns testosterone into dihydrotestosterone (DHT), which is harmful testosterone for hair. DHT shows its effect by attaching the androgen receptors in the hair roots.
Frequency of Androgenetic alopecia
In %94.96 of men after puberty, the forehead hairline draws back a little, and approximately %50 of men lose their hair on the forehead and the top of the head. %30 of men have shown alopecia symptoms when they are 25 years old, %40 of men in their 40s, and %50 of men in their 50s. Also, androgenetic alopecia occurs %20-30 of women population.
