Dandruff affects the scalp and causes flakes of skin to appear - it is a common condition. Our skin cells are forever renewing themselves. When the skin cells on our scalp are renewed the old ones are pushed to the surface and out of the scalp. For a person with dandruff the renewal is faster, meaning more dead skin is shed, making the dandruff more noticeable. Dandruff can also occur if the scalp is frequently exposed to extreme temperatures.

Researchers at Oregon State University have found one gene in the human body that appears to be a master regulator for skin development, in research that could help address everything from skin diseases such as eczema or psoriasis to the wrinkling of skin as people age. Inadequate or loss of expression of this gene, called CTIP2, may play a role in some skin disorders, scientists believe, and understanding the mechanisms of gene action could provide a solution to them.
