Why do flakes appear on the scalp?

ANSWER

The cause of dandruff is unclear. Hormones are suspected since dandruff peaks in the teen years. Or a type of yeast that over-grows on your scalp may play a role. But it has nothing to do with poor hygiene.

Flakes run in families. You're more likely to get them if you're a guy, overweight, or have oily skin. Some conditions, like Parkinson's disease, can also cause dandruff.
