What are the common hair loss causes? by Richard Mitchell

All men and women produce male hormones such as testosterone and DHT. These have a useful role to play in both sexes but obviously occur in widely differing concentrations. It is the higher levels of androgens found in males that explains why this form of hair loss affects men more than women.

In brief, these hormones affect the hair growth cycle as follows:

1. High levels of the 5-alpha-reductase enzyme occur in some cells of the hair follicle and sebaceous glands.

2. 5-alpha-reductase converts testosterone into DHT.

3. DHT causes the terminal hairs to miniaturize.

4. This leaves short, soft, fluffy vellus hairs that provide inadequate scalp coverage.

5. The growth phases gradually become shorter until these hairs are lost for good.

Alopecia areata is thought to be an immune system disorder that causes follicles to stop producing hairs in patches on the head. In severe cases it can advance to the stage where all hair on the head is lost (alopecia totalis) or even a complete absence of body hair results (alopecia universalis).

In most cases the hair will reappear on its own but until then, the condition can be very distressing to sufferers particularly as its cause can be difficult to determine. If you feel you may be suffering from this form of hair loss, seek the advice of your physician who will carry out a physical examination and conduct blood tests to help determine the cause.

Telogen effluvium is characterized by a general thinning or shedding of hair over a period of months and is most commonly found in people who have recently experienced trauma. Common causes include childbirth, major surgery, severe illness, psychological stress and chemotherapy. The good news is that the abnormal growth behavior associated with telogen effluvium is temporary and reversible.

There are numerous other less common hair loss causes that need to be discounted before a course of treatment is chosen. Traction alopecia is the loss of hair from constant pulling, usually as the 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 may include degrees of hair loss.

I hope this brief article has gotten across the message that diagnosing the real causes of hair loss is not always a straightforward process. Once you and your physician have identified a cause, then you can work towards restoring your hair to its former glory. And the good news is, most forms of hair loss can be treated successfully. The next article in this series will look at some of the best hair loss treatments currently available.
