Who, What, Hair
Is exfoliating your scalp the answer to better hair?

It can help manage greasy roots, calm flaky skin and boost hair growth
Scalp care - it’s hardly the most glamorous of subjects to talk about. However, it could hold the key to a healthier head of hair. “The scalp is the bedrock for the hair follicle, and if it is not in good condition the chances of you experiencing problems with hair growth and health increase significantly,” says trichologist, Anabel Kingsley. “In fact, research has proven that a flaky, itchy scalp can cause and/or worsen hair loss in certain individuals.”
To remove dead skin cells, debris, product, sweat and sebum, our scalp can benefit from being treated in a similar way to how we treat the skin on our face - and exfoliation forms a key part of the regimen. Providing a deeper clean that goes beyond the realms of a run-of-the-mill hair wash, it increases cell turnover and, by removing build-up, it clears the way for better absorption of the products that you put on top.
Which one's for you?
It’s a category that’s seen noticeable growth over the last couple of years and there’s now an impressive breadth of textures and formulas to choose from. Much like its facial counterparts, products range from physical exfoliators (such as scrubs) to chemical exfoliators that contain AHAs (such as glycolic acid) and BHAs (such as salicylic acid) which can be found in shampoos, leave-in treatments and masks.
Determining the one that’s best for you depends on your scalp type and personal preference. Scrubs tend to be more abrasive than acids because of their coarse particles, so sensitive scalps are best advised to proceed with caution. Is there anyone who should avoid scalp exfoliation altogether? "Psoriasis sufferers and those who suffer from some types of eczema," says trichologist, Iain Sallis. "It can stimulate the skin to produce more flakes."
How often should you exfoliate?
Again, it depends on your scalp type but also the exfoliating product used. For leave-in treatments or masks, a general rule of thumb would be to use them once a week. If you have a scalp that tends to get oily quickly though, you might be able to tolerate exfoliating twice a week. Avoid over-use though as this can end up making flaking worse in some cases. Application recommendations differ from product to product so it’s definitely worth checking the label first and proceeding with caution to begin with.
