Dandruff is a very common condition.
Everyone’s scalp regularly sheds white scales, which are dead skin
cells. In dandruff sufferers, these cells are shed every few days rather
than once a month. Characteristic white dandruff flakes can be seen in
the hair parting and against black clothing. The scalp may also be
itchy. Dandruff cannot be passed on by sharing combs or hats. The
culprit seems to be a fungus infection called P. ovale. These little
yeast cells cannot make their own fatty acids, so usually only live on
the scalp in small numbers. However, people who suffer from seborrhoeic
dermatitis may have oily skin. Greasy hair products like oils and
conditioners may also provide the yeast with food. When the yeast cells
can get enough oils, they proliferate and cause the skin cells to shed
rapidly.
Treatment revolves around killing the fungus and removing the excess
oils on the scalp. Regular hair washing with a neutral pH shampoo will
rinse off excess fats. Avoid oily hair styling products. Shampoos
containing ketoconazole will kill the fungus. A combination of a once
monthly antifungal shampoo with regular anti-dandruff shampoos weekly
will keep dandruff at bay. Alternative treatment is aimed at reducing
the number of scalp cells produced each month, and these shampoos
contain selenium. Coal tar shampoos and some steroid shampoos could also
be used in people who suffer from seborrhoeic dermatitis too.
