Question

When we rub our fingers in our hair (while having dandruff), after doing, why our fingers become less oily-like?

Answer 1

Loose, white, powdery flakes are the characteristics of a dry scalp. Dry scalp is a result of dehydrated sebaceous glands (the glands that produce the natural oil for our scalps). This dehydration can be due to cold climates, not drinking enough water or a skin condition like psoriasis.
