Hair growth is a cyclical process. All permanent hair growth cycle lasts 3-4 years. At the end, speculation falls and after a short rest period a new hair grows in its place. Naturally every one hundred hairs a day finish their growth cycle and fall from the scalp. On that overlap the hair, scalp fall approximately? 100 hairs. These numbers are considered normal physiological hair loss.
Dr. Dangorth, a dermatologist, hair, dermatological surgery and hair transplants, explains: "Hair loss is not necessarily genetic. It can be due to many reasons including: disease, weight loss, nutritional deficiencies and hormonal disorders. "
Heads hairs growing from a follicle located in the epidermis - the outer skin layer of the scalp. Creatine is produced in the follicles (Keratin), a protein that formed the hypothesis. As the amount of this protein is reduced, so that the hair will thin and weaker. After the growth phase of the hair reaches the resting phase, it stops growing speculation, away from the blood vessels which provide it with the amino acids it needs them and falls. So, in fact, she gives way to her hair will grow in the next step - re-growth phase.
Dr. Danforth , "When the body undergoes physiological changes radically, a greater percentage of follicles enter a stage of rest. This phase also often longer than usual. This situation increases the dropout rate, but no follicles caused irreparable damage and they will return to their previous state shortly after that interruption is over. Eventually the hair follicle and they produce will return to normal and the drop-out stop. "
For example, men who work in the sun physical labor, such as agriculture, construction or guides, their hair does not hurt more than men working an office job, as the physical work does not harm the hair. However, the sun can definitely make aging hair and long in the sun can cause skin aging which can eventually lead to damage to the hair as well. In general, by being a hot country, there is a fear of aging hair but not dropping out. "
Dr. Danforth , "environmental factors do not affect the hair, because my hairloss is carried out, as mentioned, from the root, so there is actually a direct hit, but the hair root itself after it has been grown. For the same reason, it is important to note that shampoo and conditioner has no effect on hair loss or growth, as well as working in the garage which requires contact with oils and fuels.
Many fear that job stress can cause hair loss. But "not proven fact that stress can cause them to drop out," reassured Dr. Danforth . "However, there is little evidence Sllhtz have any effect on the hair. It seems that the person who from the outset the balding gene is affected by the tension and stress which he finds himself, and thus the genetic system is activated prematurely. In other words, if you had to become bald at the age of 40 the process will start earlier. "
