WHEN your hair is greasy in between washes, you might be inclined to reach for dry shampoo.
But according to one beauty guru, this is the last thing you need - in fact, Tati Westbrook claims that the secret to fixing greasy tresses is in the skincare aisle.
The beauty guru, 42, is a make-up expert, social media influencer, and YouTube star with a net worth around £9.5 million.
Despite her worth, she has revealed how she executes a 10p hack to banish oily locks in seconds.
She says that it works so much better than dry shampoo that you might consider never washing your hair again.
In a recent YouTube video, Tati urged her followers who suffer with greasy hair to get an oil-reducing micellar water.
She uses the Bioderma Sébium Cleansing Micellar Water for Blemish-Prone Skin, which costs £13 for 250ml on Lookfantastic.
Then, she decants it into a spray bottle.
When her hair is greasy (particularly after a workout), Tati spritzes the micellar water onto her hair and then blasts it with a hair dryer to draw out the oil.
“It works so well, it is astonishing,” she quipped.

“The micellar water is eating up the oil, there’s no white and flakey residue from a dry shampoo, there’s no mess.
“Your hair will look so ridiculously fresh you might be thinking ‘gosh, I never have to wash my hair again’.
“It literally will elongate the bounciness and freshness of your hair.”
Tati urged gym bunnies in particular to try the hack, explaining that it’s particularly handy when her scalp is “covered in sweat”.
“You cannot put baby powder spray on sweaty hair and think that it’s going to end well - it’s not,” she said.
What’s the science behind it?
Micellar water isn't just a fancy name; it's rooted in simple yet powerful science.

IF your purse is feeling tighter than ever before and you're looking to save cash on your make-up routine, have you ever thought of trying out beauty dupes?
Here's five of the best recommended beauty buys that are almost identical to the posh versions, but for a fraction of the price.
FACE BASE: If you can't afford Charlotte Tilbury's £52 Magic Cream, why not try a dupe that costs just £5.49 from Superdrug?
TONE IT UP: If Drunk Elephant's £62 Protini moisturiser is out of your price range, you'll need to check out the new dupe in Home Bargains.
TINTING IT: With Fenty's 'game-changer' skin tint costing an eye-watering £29, a popular supermarket's affordable alternative might just be the thing for you.
GET COVERED: At £29 for a Tarte concealer, the new Primark dupe is much more affordable at just £3.50.
SPRAY YAY: For those wanting to smell fresh, without the price tag, Aldi's new Prada and Chloe perfume dupes cost a fraction of the price.
The skincare staple contains micelles, which are tiny clusters of molecules made up of a unique structure of two distinct parts.
These are hydrophilic (water-attracting) heads and lipophilic (oil-attracting) tails.
When mixed in water, these molecules arrange themselves into micelles, forming small spherical structures.
When you apply micellar water to greasy hair, the micelles spring into action.

The lipophilic tails latch onto oil, grease and impurities on the scalp and hair, while the hydrophilic heads ensure the micelles stay suspended in the water.
This dual action allows micellar water to effectively lift and remove excess oil and dirt without the need for harsh scrubbing or rinsing.
