The 'skinification' of the scalp is driving a wave of new products, from scrubs to deep-cleaning shampoos, that promise to 'detox' and improve hair health. But are they necessary?
What is scalp detox?
Desmond Tobin, professor of dermatological science at University College Dublin, says the term 'detox' is misleading. 'It's obviously a business opportunity,' he notes, as brands extend skin care lines to scalp care.
Tobin explains that these products don't remove dangerous toxins, but an occasional cleanse can be useful for some people, especially those with product buildup.
When is a cleanse useful?
Heavy product use can clog hair follicles, potentially affecting hair growth. A quick shower may not remove everything, particularly in hard water areas where minerals react with products to form residue.
People in polluted urban areas might also have chemical deposits on their scalps. However, Tobin advises that expensive products aren't necessary; a sulfate-free high-lather shampoo or double-shampooing can help break down buildup.
