Dandruff is a condition that affects the scalp, causing it to peel off for some reason. The exact cause is unclear, it may be due to 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 a sensation of mild itching: dry dandruff is associated with dry scalp, with small particles that come off easily. Greasy dandruff, in turn, is associated with oily scalp, with larger particles that tend to stick to the root of the hair. Find a shampoo adapted to your type of dandruff here!
