Some Causes of Hair Loss

It is normal to lose between 50-100 hairs a day, this is part of the hair renewal process. But most people suffer from excessive hair loss at least once in their lives. There are very possible causes, including drugs, iron deficiency, chemotherapy, exposure to chemicals, hormonal and nutritional factors, mechanical damage, generalized skin disease or local stress.

Many of these causes are temporary and some are permanent. These are some of the most common causes of hair loss.

Hormonal changes:

v  Hormones are one of the main reasons of hair loss. The male hormones collectively known as androgens have by far the biggest impact on hair loss. Most important male hormone, testosterone is indirectly related to hair loss in men. A man who has the essential genes for hair loss, a small amount of this testosterone is produced by some of the hair roots into a derivative called dihydrotestosterone that is actually responsible for hair loss.

v  When dihydrotestosterone is produced, it is present in the surface sebum (grease), which is secreted through the sebaceous glands in the skin tissue. In these circumstances, the dihydrotestosterone enter the follicle (the hole in the scalp from which the hair has come), when a hair is shed and inside there it reacts chemically. What it really does is to miniaturize the hair root and follicle. As a result, new hair will grow through the finer. When the new hair is a fine new building after Dihydrotestosterone miniaturized follicle and the hair root, and even more after your hair is even finer. This process continues until the hair is so thin that it might not be there at all, and if this happens all over the area, so a thin man, of course, on this surface and thus the hair loss occurs.

Stress:

v  Physical and mental stress has short-term effect on hair loss. It does not occur immediately with the stressful event but generally takes about 2 or 3 months after a stressful period or event has begun. Therefore, hair can be lost is that the telogen phase of hair follicles happens prematurely than is normal. As a result, you do not start to grow new hair after old hair shed. However, the stress has been removed the loss of hair will stop and the new hair starts to grow in place of that lost once more.

Skin disorder

v  Some particular types of skin disorders like psoriasis, which could be the reason for losing more hair than normal. However, when treatment begins with skin disease and hair begins to grow again.

Medication

v  There are varieties of medications, which are partly responsible for losing hair more than is normal. However, the problem can arise when you could really happen when you have received the drug for a long time., So in case of any medication, it is important to consult a doctor whether this could be a side effect of the drug taken.

Genetics:

v  It is often considered that hair loss may also occur genetically. If one’s mother’s or father’s side relatives inherit this reason he or she may also suffers from the problem of hair loss.

Iron deficiency:

v  The lack of iron in human body occasionally causes hair loss in both man and women. Women suffers from this problem generally as they loss iron during their menstrual periods and develop iron deficiency. Low iron content in diets often causes iron deficiency in human body. Taking iron supplement or iron pills can solve iron deficiency.

Childbirth and pregnancy:

v  Many women face the problem of hair loss after giving birth although it does not seem to be much hair loss during the pregnancy. This happens as the hair enters the resting (telogen) phase. This problem resolves naturally after one to six month as hormone levels start to come back to normal after woman’s body recovers from her pregnancy.

Poor blood circulation:

v  Baldness occurs not by inheritance or as a result of the effects of testosterone on hair follicles in the target area. On the contrary it is due to poor blood circulation in the scalp (from a variety of causes) and for inadequate nutrients in the blood. Another reason that is poor drainage of waste products thorough the lymphatic system.

Mechanical damage:

v  Mechanical damage to the hair may occur either through intentional or unintentional. Some stresses continuously pull the hair until it comes out. Hairs styling treatments, trichotillomania or hair pulling and hair braids or weaves are responsible for mechanical damage of hair. Irregular chemical treatment like dyes, tints, bleaches, straighteners, relaxers and permanent waves make and weak the hair.
