common causes of hair loss
Sunday, May 29th, 2011One of the most critical aspects of the treatment of hair loss is the tendency of many people to examine solutions without having to look for what caused the loss in the first place.
In the best case, concerned money on inappropriate ‘wonder drugs’ waste or even legitimate treatments that unfortunately is not suitable for their particular needs. In the worst case, some people risking their health by self-prescribing powerful drugs. I do not have a problem with hair loss suffer save money by buying cheap generic drugs on the Internet, but I feel strongly that they at least try to confirmation from their doctor that a particular drug meets their individual needs.
Before examining the most common causes of premature hair loss, we must understand that some of the hair loss is totally normal. Hair grows from follicles that developed the tiny organs in the skin to grow a single hair that the repetitive cycle follows are:
1. Lengthy growth period (Anagen Stage) – this phase lasts usually between two and seven years with an average growth rate of six inches (15cm) per year.
2. Short transition period (catagen) – this transitional period lasts about two minutes to four weeks ago. During this phase replaced the hair shaft and is moved upwards within the follicle.
3. Resting period (telogen stage) – This phase lasts about three months allowing the hair to loosen itself from falling out.
At this point a new hair begins to grow thus repeating the normal cycle of hair growth. Unfortunately, a number of factors can interfere with the natural hair growth process leading to forms of thin hair and premature hair loss.
Androgenetic alopecia is the most common cause of hair loss, probably accounting for as much as 95% of hair loss in men and women. It is usually associated with aging and develops in predictable stages over varying periods. Each follicle follows a genetically programmed growth cycle with some follicles coded to remain for a shorter time than other active. This leads to the development of hereditary baldness patterns that are so familiar to us all.
occur for this type of hair loss, must be available the following factors:
1. occur both genetic predisposition for hair loss (as explained above).
2. The presence of male hormones.
3. Aging – in other words, to allow time for the first two factors have an influence.
All men and women produce male hormones such as testosterone and DHT. They have to play a useful role in both sexes, but obviously occur in very different concentrations. It is the higher of androgens in men found that explains why this form of hair loss affects more men than women.
In short, these hormones affect the hair growth cycle as follows:
1. High concentrations of the 5-alpha reductase enzyme in some cells of the hair follicle and sebaceous glands may occur.
2. 5-alpha reductase converts testosterone into DHT.
3. DHT leads to the miniaturization of terminal hairs.
4. This leaves short, soft, fluffy vellus hair, scalp, provide inadequate coverage.
5. The growth phases gradually shorter until these hairs are lost for good.
Alopecia areata is probably an immune system disorder, the follicles, the production of hair in patches are caused on the head. In severe cases it can to the stage where all hair is lost on the head (alopecia totalis) or even a complete absence of body hair results (alopecia universalis), ahead.
In most cases, the hair on his own, but again only to be very distressing, the condition can be difficult to determine for patients particularly as the cause. If you think you may be suffering from this form of hair loss, make you seek the advice of your doctor’s physical examination and blood tests will be carried out to determine the cause.
Telogen effluvium is characterized by a general thinning or shedding of hair over a period of months and is most common in people who have recently experienced trauma was found. Common causes include childbirth, major surgery, serious illnesses, psychological stress and chemotherapy. The good news is that the abnormal growth behavior refers to telogen effluvium is temporary and reversible.
There are numerous other less common hair loss causes, which is to be reduced before treatment must be chosen. Traction Alopecia is the loss of hair from constant pulling, usually as a result of hair styling. Broken hairs can result in thinning, often caused by excessive styling or exposure to chemicals and sun. Finally, severe illnesses or nutritional deficiencies can cause side effects that can include the accounts of hair loss.
I hope this short article has given the message that diagnosing the real causes of hair loss is not always an easy process. If you and your physician have identified a cause, then you can work to restore your hair to its former glory. And the good news is that most forms of hair loss can be treated successfully.
