Why do we get dandruff? |

Dandruff is a condition in which our scalp sheds skin cells in the form of white flakes.
A yeast called Malassezia globosa, is one of the mostly accepted reasons for causing dandruff.
Malassezia globosa is naturally present on our scalp.
It feeds on sebum and releases oleic acid.
Now, some people are sensitive to this oleic acid.
When it penetrates into the upper layers of their skin, it causes inflammation.
Hence, in response to this inflammation, their skin sheds a large number of skin cells at a higher rate.
These cells then join together forming white flakes, thus causing dandruff.
