Hyaluronic acid, salicylic acid, clay, niacinamide...they're the types of ingredients that make up all of our favourite skincare products, from serums to masks and moisturisers.
But what if we told you that they can also work wonders on your scalp?
The hair industry is currently taking inspiration from the skincare sphere, with brands like Sachajuan, Nanogen and Redken, to name but a few, formulating shampoos, serums and masks with ingredients you'd usually slather all over your face.
The best part? There are heaps of benefits, like moisturising and exfoliating a dry, flaky scalp, reinforcing fragile strands and even encouraging hair growth - perfect if your tresses always seem to be stuck at shoulder length.
Hairstylist and trichologist, Guy Parsons, even predicts that 2018 hair trends will see a huge interest in scalp health and traditional skincare ingredients, essentially because 'our scalps are essentially an extension of our faces.'
And according to Sam Burnett, owner and creative director of , these skin-hair hybrids are nothing short of game-changing, because actually, the skin and hair aren't that different after all.
'One of the biggest reasons for this advancement in product technology is the understanding that skin and hair are actually composed of similar proteins and fats,' he says. 'By taking the same approach to the anti-ageing process with our skin, we can apply the same approach when it comes to our hair. It's 100% a step in the right direction with products containing super stem cell and antioxidant ingredients that can even slow down the process of going grey.'
And who doesn't want hair gorgeous enough to rival a shampoo-ad model, right?
