Why do we only get dandruff on our scalp and not the rest of our bodies?
In: Biology
Most dandruff comes from using shampoo too frequently. Many mistake dandruff as the result of dirty hair/scalp. This is not always the case and can become a counter productive shame cycle. Person notices more dandruff, they shampoo more. This dries out your skin cells that need some oil for plasticity and just like anything else that dries out, becomes brittle and falls apart. The degreasing chemicals in most shampoo/soaps do a great job of bonding to and removing oil. The problem is they remove ALL the oil and the scalp dries out = dandruff.
