Dandruff is a condition of the scalp that causes flakes of skin to appear. Dandruff is a common condition, which is marked by itching. In some cases it can be embarrassing and not easy to treat.
Fortunately, dandruff can be controlled. In mild cases, the person need only find a suitable shampoo which contains a gentle cleanser. When the dandruff is severe, a medicated shampoo will be required.
Human skin cells are forever renewing themselves. As skin cells in the scalp are renewed, the old (dead) ones are pushed to the surface and then out of the scalp; they are literally expelled.
For people with dandruff, the new cells are produced at a faster rate than they die, resulting in more skin being shed, making dandruff more noticeable.
