What is dandruff?

Dandruff is a fairly common condition that affects up to half the world’s population. Although its symptoms can leave even the best of us feeling unconfident and anxious, understanding what dandruff is and what causes it can be the first step to eliminating it.


Dandruff is a skin condition that affects your scalp and hair causing grey or white coloured flakes to appear. These flakes are actually your scalp’s old skin cells, shedding at a rate much higher than usual.

A healthy scalp sheds dead skin cells around once a month and quickly makes new cells to replace them. When this process speeds up, your scalp begins to produce an excess amount of dead skin which leads to dandruff.


A number of factors, such as oily skin, emotional stress or washing your hair too little can lead to dandruff, but there’s still some debate surrounding its exact cause. The researchers behind CLEAR Anti-Dandruff Shampoo have suggested that a weakened scalp barrier – meaning the scalp has less moisture and weaker integrity/ weaker protection– as well as the presence of a microbe called malassezia can lead to the occurrence of dandruff.   

Malassezia is a fungus that grows in oil rich areas such as the chest, face, upper back and scalp. The exact role malassezia plays in dandruff is still not entirely clear. However, scalps with dandruff do tend to have a higher presence of malassezia. It is believed that a compromised scalp barrier allows irritants produced by malassezia to penetrate the scalp and further aggravate dandruff. For most people, removing malassezia decreases the symptoms of dandruff.    


Low moisture in the scalp leads to a weakened scalp barrier, which makes you all the more susceptible to the appearance of dandruff. Regularly washing your hair and scalp with a scalp nourishing shampoo is the key to restoring moisture and regaining a healthy scalp barrier.

An anti-dandruff shampoo like CLEAR Complete Soft Care Shampoo, infused with a healthy blend of 10 nutrients and botanical actives, revives scalps and hair. When used regularly, it nourishes and repairs the scalp's natural protection barrier, leaving your hair soft, healthy and free of visible flakes.
