Description: Every month, all the cells of the entire skin layer, the epidermis, renew. The lower cells migrate upwards to the stratum corneum and scale off after a while as tiny invisible particles. If this process is disturbed, the tiny particles stick together to form larger clumps of cells, dandruff. Dandruff is non-inflammatory in nature and it is not a disease but rather a cosmetic problem. But for many they will remain a nuisance for their whole life, especially in winter!
