Identify the most common causes of hair loss. Hair is the fastest growing tissue in the body of the second, after the bone marrow. Hair loss is caused by hair follicles stop producing hair grower cells. The loss of some or all of the hair is called alopecia. Hair loss usually develops gradually and may spread.
The most common cause of hair loss
The most common cause of hair loss is genetic, inherited tendency to lose hair from either or both parents. The medical term for a genetic predisposition for hair loss is “androgenetic alopecia”.
In androgenetic alopecia, the genes influence how the hair grows. They trigger a sensitivity to a class of hormones called androgens, including testosterone, which causes hair follicles to shrink. Shrinking follicles produce thinner hair and eventually none at all. Thus, androgenetic alopecia is caused by the body’s failure to produce new hairs and not by excessive hair loss.
Men generally go bald on the forehead or over the head. In men, the hair on the head has a genetic sensitivity to the male hormone testosterone while the hair on the sides and back of the head does not have this genetic trait and is therefore not affected. For this reason the hair taken from the sides and rear (donor hair) to maintain their genetic predisposition when transplanted and growing when it moved to the top of the head where hair loss has occurred.
For a woman, female pattern baldness is the most common type of hair loss. It can begin at puberty, but is most commonly seen after menopause. Women experiencing overall thinning of hair all over the scalp while the frontal hair generally remained intact.
Other causes of hair loss
- Side effects of medication or medical treatment; Certain drugs used to treat gout, arthritis, depression, heart problems and high blood pressure may cause hair loss in some people.
- Stress delayed; A common form of hair loss occurs two to three months after your body stress. Stress causes a high proportion of hair follicles entering the resting stage all at the same time. A few months later, after a break in a long time, the follicles begin to shed their hair at the same time. Because the stressful event happened months ago, most people do not connect with their hair loss. This is a temporary condition, and new hair starts to grow in a few months. Stress can also trigger genetic hair loss. If your hair loss is caused by stress, your hair will fall out faster.
- Adequate protein when diet; Some people are on a diet low in protein, or have severely abnormal eating habits, may develop protein malnutrition. The body will save protein by shifting growing hair into the resting phase. Big hair shedding can occur two to three months later. This condition can be reversed and prevented by eating the right amounts of protein when dieting, maintaining adequate protein intake.
- Iron deficiency; Iron deficiency sometimes resulting in hair loss. Iron deficiency is common to women during menstruation and pregnancy and can be corrected through proper diet or iron supplements.
- Pregnancy and childbirth; Hair loss that is connected to pregnancy usually occurs after delivery. When a woman is pregnant, her hair grows at a very high speed. However, after a woman delivers her baby, many hair enters the resting phase of the hair cycle. It is a natural process and happens in many cases.
- Birth control pills; Hair loss in women while taking birth control pills usually have a tendency to inherit hair thinning (androgenic alopecia). If hair thinning occurs, a woman can consult her gynecologist about switching to birth control pills. If a woman has a history of female pattern loss in her family, she should tell your doctor before taking the pill.
- Scalp infection; Infections such as ringworm can invade the hair and skin of your scalp, leading to hair loss. Once the infection is cured, the hair will usually grow back.
- Thyroid disease; Overactive thyroid and not overactive thyroid, both can cause hair loss. Hair loss caused by thyroid disease can be treated with proper care.
- Hair loss in part (alopecia areata); Alopecia areata is classified as an autoimmune disease, but the cause is unknown. This disorder causes hair follicles to stop producing hair. In most cases the condition is temporary and will go away by itself within 6-7 months, and hair will grow on a bald head.
- Tied hair (traction alopecia); Traction alopecia often occur in tightly braided hairstyle.
- Hair care; Tying hair too tightly can cause your hair to fall out. You may lose hair around the edge of the hairline, especially around the face and forehead. Using curling irons or dyes continually can also cause hair loss. Hair usually grows back when the activity is stopped.
- Hair dryers can cause hair loss; The reason is that extreme heat can damage proteins in the hair, making them brittle and likely to break. Combing the hair for drying causes more damage. If you use a hair dryer, it should be set at the coldest setting. Hair dyes, perms and hairsprays do not affect thinning hair.
Hair loss is not caused by a disease, but related to aging, heredity and testosterone. In addition to the pattern of men and women as well as combinations of these factors, other possible causes of hair loss, especially if in an unusual pattern.
