Dandruff is a condition that affects the scalp, causing it to peel for some reason. The exact cause is unclear, may be involved in genetic or environmental factors, periods of stress, improper shampoo or some sensitivity to any product (shampoo, mask, paint, etc.). There are situations of dry dandruff and oily dandruff, both with the sensation of slight itching: Dry dandruff is associated with a dry scalp, with small particles that easily come off. Oily dandruff, in turn, is associated with an oily scalp, with larger particles that tend to stick to the root of the hair.
