-Dandruff is increased turnover of skin cells on the scalp, leading to large amounts of flaking, and possibly redness and itching. In people with dandruff, skin cells develop and die in 2-7 days, in contrast to a cycle of one month in people with no dandruff. It is a condition that can fluctuate depending on the season, usually becoming worser in winter. Half of the population is affected by dandruff at some point; in people older than 50 it is not very common.

+M. globosa has no ability to manufacture its own fatty acids, which are essential for life, and so relies on human sebum for its source. The way it causes dandruff:
 # The fungus produces 8 types of lipase and 3 types of phospholipase enzymes, which help to break down sebum into free fatty acids and glycerol.
-# It feeds on the satirated fatty acids, while it leaves irritating unsaturated '''oleic acid''' behind.
+# It feeds on the saturated fatty acids, while it leaves irritating unsaturated '''oleic acid''' behind.
 # The oleic acid then penetrates the scalp, irritates the skin and triggers faster turnover of skin cells in susceptible people.
 ## This has been proven by removing all of the fungus and treating the scalp with pure oleic acid in susceptible and non-susceptible individuals.
