Most often, alopecia occurs (but is not limited to) in women following menopause as hormone levels in the body change. "Changes in the levels of the androgens (a male hormone) can affect hair production. For example, after the hormonal changes of menopause, many women find that the hair on the head is thinned, while facial hair "is coarser". Genetics can also be a determining factor. Women with older female family members who endured thinning of the hair are more likely themselves to be subjected to rogenetic alopecia.
Women with alopecia do not lose their hair in the same fashion men do. Usually, the frontal hair line remains, but the hair loss can be noticed as a general thinning of the hair on the top and front of the head.
Alopecia Hair Loss
Alopecia is a common disease that results in the loss of hair on the scalp and elsewhere. Alopecia occurs in males and females of all ages, but onset most often occurs in childhood. There are three types of Alopecia: Alopecia Areata, Alopecia Totalis and Alopecia Universalis.
What is Alopecia Areata?
Another type of Alopecia, known as Alopecia Areata, it is usually temporary. It affects approximately 2 percent of the population and can involve hair loss on the scalp or the body. Its specific cause is unknown. With Alopecia Areata, baldness usually occurs in small, round, smooth patches. Hair loss may be on the scalp only, or body hair may be lost as well. Alopecia Areata is classified as an autoimmune disease, but the cause of it is unknown. In fact, people who develop this type of baldness are generally in good health. A family history of Alopecia Areata makes you more likely to develop it. Unlike Androgenetic Alopecia, hair will generally grow back. But it may take several years.
What triggers Alopecia Areata to start or stop?
Current research suggests that something triggers the immune system to suppress the hair follicle. It isn't known what this trigger is, and whether it comes from outside the body like a virus, or from inside. Recent research indicates that some people have genetic markers that increase both their susceptibility to develop Alopecia Areata, as well as the degree of disease severity.
Is Alopecia Areata hereditary?
Yes, heredity plays a role. In one out of five persons with Alopecia Areata, someone else in the family also has it. Those who develop Alopecia Areata for the first time after the age of thirty years have less likelihood that another family member will have it. Those who develop their first patch of Alopecia Areata before the age of thirty have a higher possibility that another family member will also have it. Alopecia Areata often occurs in families whose members have has Asthmas, Hay fever, Atopic Eczema, or other autoimmune disease such as Thyroid disease, early-onset Diabetes, Rheumatoid Arthritis, Lupus Eryhemaosus, Vitiligo, Pernicious Anemia, or Addison's disease.
What other parts of the body are affected?
In some people, the nails develop stippling that looks as if a pin had made rows of tiny dents. In a few, the nails are severely distorted. However, other than the hair and occasionally the nails, no other part of the body is affected.
Involves hair loss over the entire scalp. The affected follicles become very small, drastically slowing down production. The hair follicles remain alive and are ready to resume normal hair production whenever they receive the appropriate signal. Hair growth may occur without treatment and even after many years
Indicated by hair loss of the entire body.
Androgenetic Alopecia (FEMALE PATTERN HAIR LOSS)
It is the most common type of hair loss seen in women. Genetically, hair loss can come from either parent's side of the family. The technical term Androgenetic Alopecia is where the hair is genetically programmed to gradually fall out, occurring in 1 out of 5 women. This condition is also known as Female Pattern Hair Loss. This is seen as hair thinning predominately over the top and sides of the head. It affects approximately one third of all susceptible women, but is most commonly seen after menopause, it occurs more commonly between the ages of twenty and forty-five, although it may begin as early as puberty. True hair loss occurs when lost hairs are not re grown or when the daily hair shed exceeds 125 hairs. At menopause, the level of estrogen usually declines which is why the effects of Female Pattern Hair Loss are often seen among this age group. It's believed that this type of hair loss is caused by an inherited sensitivity in the hair follicles to the male hormones testosterone. Yes, women do have testosterone in their bodies; however the female hormone estrogen usually protects the female body against the effects of testosterone. In Female Pattern Loss, testosterone in the scalp breaks down and one of its by-products, Dihydrotestosterone (DHT) , interferes with the hair follicle, causing it to atrophy (resulting in smaller hairs of less pigment), and finally, to wither and die, when it finally produces no hair at all. Female Pattern Hair Loss generally occurs in a woman slightly later in age than it occurs in a man. Where Male Pattern Baldness usually affects the hairline, women generally experience an overall thinning across the entire scalp.
