Knowing forms of hair loss in Androgenic alopecia part 2 - Genetics and Hair Loss

Genetics and Hair Loss

Genetic is one of factor which causes of androgenetic alopecia. The two parents play a role in this. Paternal Hair loss have been shown to relate to the alopecia of sons, while variation in the androgen receptor gene (AR) which can also relate to the baldness, X relate and so inherit from grandfather or grandmother.

Androgen Receptor permit the body to reply appropriately to dihydrotestosterone and other, dissimilar androgens. Study suggest that variation [in] the AR gene which led to increased activity of androgen receptor which improved in hair follicle. That omit unclear, however, how these genetic chages increases the incidence of hair loss patterned in both men and woman with androgenetic alopecia.

heritage of byword Pattern androgenetic alopecia is unclear because many factor like genetic and environmental likely will be entangled. This condition tends to cluster in families, however, and having a close relative with patterned hair loss appears to be a risk factor for developing the condition.

Knowing forms of hair loss in Androgenic alopecia part 1

Hair loss has a many forms. Below is the one forms of hair loss :

Androgenic alopecia - The most common type of hair loss, also called male pattern baldness

Male pattern baldness in a 40 year old man.

The first common hair loss form is Androgenic alopecia (also known as androgenetic alopecia or alopecia androgenetica). This is most common form of hair loss int both, men and women. Beginning above both temples, and hair is lost in a well-defined pattern. Hair is lost well-defined and recedes to form a characteristic "M" shape. In the crown of the head hair also thins, often progressing to partial or complete baldness.

In the women, hair loss is different from male-pattern baldness. In all over of the head, the hair becomes thinner, and also the hairline does not recede. Androgenetic alopecia in women rarely leads to total baldness.

Androgenetic alopecia is causes by a variety of genetic and enviromental factors likely play a role.Although researchers are studying risk factors that may contribute to this condition, most of these factors remain unknown. Researchers have determined that this form of hair loss is related to hormones called androgens, particularly an androgen called dihydrotestosterone (DHT). Androgens are important for normal male sexual development before birth and during puberty. Androgens also have other important functions in both males and females, such as regulating hair growth and sex drive.

Know The Reason why Hair Loss

With each passing day if you are losing your hair in spite of all necessary precautions your alarm bells should start ringing. Chances are that you might be suffering from a hormonal imbalance that is causing hair loss and other hair related problems. Such kind of problems if remain undetected for long may even result in thinning of hair and cause baldness. Androgenic alopecia as the hair experts refer may lead to hair loss in men as it directly affects the hair follicles.

Hair loss and thinning of hair are the common symptoms primarily associated with androgenic alopecia. Also called as pattern hair loss or pattern baldness, this condition is commonly thought to be caused by excessive amount of a testosterone by-product called DHT (dihydrotestosterone) in the system. The speed at which hair loss occurs in androgenic alopecia is dependant on age progression, the hereditary tendency of the individual in relation to hair loss and of course, the presence of DHT in the hair follicles.

DHT is a highly active form of testosterone, which not only affects hair but has an overall tremendous impact on various aspects like manly behavior, sex drive and aggression. It is a naturally occurring hormone which is associated with sexual development in males. DHT is produced from testosterone in the prostate, various adrenal glands, and the scalp. Recent researches have led the hair experts to conclude that this is the androgen which is responsible for male pattern baldness. DHT has a very high affinity for the androgen receptor and is estimated to be five to ten times more potent than testosterone.

Once affected, DHT fails to recognize the hair follicles and treat them as foreign objects in the body. As a result of auto-immune response, it slowly begins to reject the follicles leading to hair loss. Follicles at the front, top, and upper back of the head in most men start withering out resulting in baldness if they remain undetected for long. It is quite possible that it may go unnoticed during its initial stages when you are busy looking for a hair oil or shampoo that can control your hair loss.

As a result of absence of any treatment that can inhibit DHT either through an oral or parental dose or local treatment to the scalp, your hair follicles soon become thinner, shorter, and ultimately may not grow back. With time, the action of DHT may cause each hair follicle to decay and they may gradually die. Some hair follicles may simply shrink to the size they were when you were an infant and produce weaker hair. This tends to grow finer and thinner hair until they are too fine to survive.

It is important that you consult a hair expert at the earliest to identify the exact cause and find out a cure for hair loss. A qualified hair expert can analyze your hormonal secretions in the body to determine the exact cause and even recommend a baldness cure for you if desired. You may find yourself lucky in getting your healthy hair back.
