Hair Loss: Causes and Possible Diseases

Hair loss is considered a curse by many. Years ago, hair loss is just a normal cycle where a big wig would hide the near balding head. Big wigs were a sign of wealth, power and beauty and the only down-side then was the excessive sweating. Kings and emperors adorned themselves with pompous hair with big curls. But that is not the case anymore where a big wig is not a sign of power no fashion.

But man’s imagination has no boundaries; wigs are simply not acceptable but hair growth serums are invented, hair extensions and hair volumizers are now standards in many hairdressing shops. There are a varieties choose from: Long or shirt, red, brown, black, pink, green and many more colors are on display whole year round.

But what exactly are the causes of hair fall?


Hormonal-hereditary hair loss

The cause of the hormonally-hereditary hair loss is a genetic sensitivity of hair follicles to a particular form of the male sex hormone testosterone. The growth phase (anagen) of the hair is getting shorter and the growing follicles shrink. They eventually only produce short, thin, barely visible wool hair (vellus). This may persist or eventually also turn out to be reproduced without any hair.

Of androgenicalopecia are primarily affects young men. Although women also produce small amounts of testosterone, women are very rarely affected by hair loss due to testosterone. They are, however, have their own rare hormonal related hair loss and they are particularly at risk when they are at menopausal stage. Hormonal changes in women promote hair loss but not all women are subjected to this.


Circle Round Hair Loss

The exact causes of alopecia aerate are not yet understood. Many studies suggest that the circular hair loss is caused by an immune system disorder. One speaks of autoimmune disease: like the body’s own immune cells mistakenly attacking the hair follicles where hair growth stops and eventually falls out. It is believed that the hair roots fall into a “sleep state” from which they sometimes wake up suddenly again and again produce hair.

This theory follows persons on interest with autoimmune diseases such as vitiligo. Some of the children with alopecia aerate also have eczema or hay fever.
An involvement of the genes in the development of alopecia aerate suggests, among other things towards the fact that this type of baldness runs in families at 20 percent of patients.

Suspicions that circular hair loss can be triggered by emotional stress, stress or environmental factors such as wood preservatives or proximity to mobile phone masts but this particular theory is yet to be proven scientifically.


Diffuse hair loss

In diffuse alopecia, the hair roots are damaged – this results in a diffuse hair loss. The causes can be many. The most important are:

  • Medication (eg, heparin, cytostatic under chemotherapy)
  • Infectious diseases (eg, typhoid, scarlet fever, severe flu)
  • Thyroid dysfunction (eg, hyperthyroidism )
  • Heavy metal poisoning (such as arsenic or thallium)
  • long-term malnutrition by crash dieting or fasting
  • Malnutrition as a result of impaired food utilization in the intestine and liver
  • Hormonal changes during pregnancy or after birth, by the deposit of the pill or when going through menopause
  • inflammatory scalp diseases (such as psoriasis)
  • Stress
  • Radiation therapy for cancer
  • normal part of aging

Other causes of hair loss

  • By a fungal infection on the head (tineacapitis) or hair fall from the infected sites.
  • Skin diseases such as psoriasis (psoriasis) can also affect the scalp. Then, the hair growth effect, and hair loss may occur.
  • Congenital abnormalities
  • Loose anagen hair: Where the hair structure is changed. This is an inherited defect. The hair is thin, brittle and loose. When combing the hair are pulledfrom the scalp and falls out easily.
  • Traumatic alopecia: This leads prolonged pressure or constant rubbing and scratching in the same places for hair loss.
  • Traction alopecia: A strong train at the hair root causes them to be damaged. Thus, as certain hairstyles such as tight braids tied in places eventually lead to hair loss.
  • Compulsive “playing” with their hair, tearing or cutting: Affected are under psychological stress, and obsessive actions bring them short-term relief.
  • Medications: A variety of drugs can cause hair loss (eg also a diffuse hair loss). These include cancer drugs (cytostatics), anti-high cholesterol (lipid lowering agents), antidepressants, beta-blockers and ACE inhibitors (for high blood pressure and coronary heart disease).
  • Other causes: deficiency diseases (eg iron or zinc deficiency), X-rays, syphilis (syphilis), infections and other factors may be the cause of hair loss.
