Flakes are probably the most well known symptom of dandruff. But what causes them to appear?
What causes dandruff?
There’s a naturally occurring microbe present on your scalp called Malassezia globosa. It breaks down your natural scalp oilsinto other substances including oleic acid, to which around half of people are sensitive.
This causes irritation, and the skin’s natural response is to increase cell turnover to replace the damaged cells.
How do flakes form?
The scalp tries to shed the irritant along with the skin cells. In just a few days, a dandruff sufferer can actually produce as manynew cells as a healthy scalp produces in a whole month!
The excess skin cells clump together and become the flakes that we recognise as dandruff.
Unfortunately, when new skin cells are being produced so rapidly, they don’t have quite enough time to develop and mature properly.This means that dandruff skin has an unhealthy and more disorganised structure.
The weakened skin is 'leaky' – less effective at protecting us from our environment and keeping essential moisture in.
