Until recently, our scalps have received little attention, with the bulk of products geared towards our mid-lengths to ends. Yet, according to the experts, scalp and hair health go hand in hand – so if your scalp is irritated, dry or flaky, your hair will likely be suffering too. ‘Your scalp is the bedrock of your hair follicles,’ explains Annabel Kingsley, trichologist. ‘If you think of each hair as a flower and your scalp as the soil supporting it, it makes complete sense to nourish and care for your scalp.’ Beauty e-tailer, Cult Beauty, has seen a 190 per cent growth in sales of scalp products over the past year, with the top seller being an exfoliating shampoo. I spoke to the industry's experts to find out if and why a scrub should be an essential part of your haircare routine…
Do you need to add a hair scrub to your haircare regime?
‘Like the skin on your face, your scalp benefits from gentle weekly exfoliation,’ explains Kingsley. 'Exfoliating masks help to remove dead skin cells and flakes and can improve the overall health of your scalp.’ You may think that washing your hair is enough to keep your scalp clean, but as hairdresser, Michael Van Clarke, explains ‘that 30 second shampoo will not have a huge impact on the build-up of sweat, oils, dead skin cells and styling products.’ Scalps need to breathe easy, so periodic exfoliation is necessary to remove the detritus and unclog the hair follicles.
What are the main benefits of a hair scrub for your scalp?
As with the skin on the rest of your body, your scalp contains sebaceous glands that produce sebum (oil). ‘When balanced, sebum can help the hair look soft and shiny. But a build-up of sebum on the scalp can clog pores and feed the bacteria that leads to dandruff,’ explains Van Clarke. ‘This clogging of the hair follicles over time can lead to thinning and loss of hair.’ So, exfoliants will help to unclog the follicles, improve the scalp health and thus promote healthy hair growth.
How often should you use a hair scrub and how should you apply it?
It depends on the condition of your scalp. 'If your scalp is flaky, itchy, or dehydrated, use a targeted scalp mask twice a week until symptoms clears,’ says Kingsley. Otherwise, once a week is enough.
‘Apply a hair scrub in 1-inch partings from ear to ear – massage into your scalp for a couple of minutes, being firm yet gentle.’ Kingsley advises against roughly rubbing the scalp as this can irritate it, cause the hair to tangle and even break strands.
