According to doctors, at any given moment, around 90% of a person’s hair volume is subjected to a level of continuous growth which spans about four to five years. The 10 to 15% of the remaining volume, on the other hand, is in a level of rest which normally lasts up to two to four months. Once hair reaches the conclusion of this resting stage, it is shed.
Normally, a person is supposed to lose around 50 to 100 hairs a day. However, you should be mindful to spot any abnormal or quick hair thinning.
One of the main causative factors of hair loss is heredity. People who suffer from the genetic condition known as Androgenic Alopecia lose their hair due to the action of a hormone called dihydrotestosterone. The presence of excess amounts of this hormone in a person triggers hair loss.
Another factor which can cause hair loss is stress. People who suffer from the chronic forms of stress can make their hair follicles move into the level of resting much earlier than normal, resulting in acute hair loss after several months.
If you are not careful enough, the actions of chemicals used on hair as medicine and styling can have a strong impact on the triggering of hair loss.
Lastly, people who suffer from the disease known as Alopecia Areata are highly prone to suffer from hair loss. This disease makes the body react to it by having antibodies act on hair follicles. As a result, a person can initially lose hair in the shape of circular areas on the sides and the back of the head, and the advanced stages may cause complete baldness.
