Alot of us find ourselves wondering what the causes of hair loss or sudden hair loss are. Under normal circumstances characteristically we lose approximately 50 to 100 scalp hairs each day. In cases of unusual hair loss, this number increases so that you may find unusually large amounts of hair accumulating in hair brushes, on clothing, and in the drains of sinks and tubs. At the same time, you may notice that your hair is generally thinner, that your part is wider, that your hairline has a different margin, or that one or more bald patches have appeared.
When hair loss is to the result of drug side effects, the hair loss often is generalized (all over the head), while in tinea infections and alopecia areata, the hair loss occurs in small patches. Also, tinea infections can cause additional symptoms, such as scaling of the scalp, or areas of broken hairs that look like black dots. In traumatic alopecia, the area of hair loss depends on the method of hair injury and follows the pattern inflicted by hot rollers, braiding or chemical treatments.In male-pattern baldness, the hairline usually begins to recede at the temples or crown first, followed by thinning at the top of the head. Gradually, the crown area becomes totally bald, leaving a fringe of hair around the back and sides of the head.
