Hot heads

Your scalp is dry and itchy, but you cant see any flakes. Could it be dandruff? Quite likely. Just like the rest of your skin, cells on your scalp are continually being sloughed off as new ones are born. Dandruff comes in several forms, but the most common cause is an overgrowth of pityrosporum ovale. This yeast occurs naturally on all scalps but in 20 percent of the population.
