This active non-toxic and non-allergenic ingredient has a keratolytic (soothing) effect that helps clean and heal the scalp. By increasing the water content in your skin (scalp), it increases your leukocytosis (white blood cell count) which helps to fight off bacteria, dandruff and dry skin which can build up on your scalp prevent hair growth. Because of this cleaning property, allantoin works as an anti-inflammatory for your skin.
