One of the most common disorders of the scalp is dandruff, a condition that affects men and women of all ages and races. There are plenty of myths about dandruff, about why it occurs and how to treat it. Facts on this topic seem far and few between. Having dandruff is not a sign of poor hygiene, although poor hygiene can cause the condition. There are different types of dandruff, each one with its own characteristics. Dandruff is not to be confused with dry scalp or the normal flaking off of dead scalp cells.
The body is in a constant state of renewal. Each day millions of skin cells die and are replaced. This is also true of the scalp. However, these flakes of dead scalp cells should not be mistaken for dandruff. Dandruff is a disorder of the scalp, with the medical name pityriasis. The exact cause of dandruff is unclear, as there may be more than one cause. One theory suggests that dandruff is caused by a bacterial infection. I think that there's accuracy in that theory, although the exact microbe responsible has yet to be identified. For all we know, there may be many microbes that can cause dandruff. Some people suggest that dandruff may be hereditary, but I don't think that theory is true. I have many clients who have had dandruff, yet their children do not show any signs.
Dandruff occurs when the scalp sheds its epithelial cells, which are the cells on the surface. Under normal conditions, these cells would freely fall from the scalp. With dandruff, the epithelial cells accumulate on the scalp near the roots of the hair. If dandruff is neglected for too long it may lead to premature hair loss. It is advisable to treat the condition as soon as it is noticed to avoid worsening.
Many things tend to increase the severity of dandruff, such as harsh shampoos, improper diet, poor scalp circulation, and general uncleanliness. Among the treatments available are medicated shampoos and scalp treatments. Both of these remedies should be readily available at a good salon. It is also believed that some forms of dandruff may be contagious, so it is a good idea to wash and clean any brushes or combs that come in contact with the scalp.
There are two main types of dandruff. Pityriasis capitus simplex is referred to as dry dandruff. This is the type most people are familiar with. This is the type that leaves those embarrasing flakes on your shoulders. Dry dandruff is recognizable by itching of the scalp and small white-colored scales.
