The precise trick a hairdresser uses to cover grey hair in 10 seconds
A grey hair that appears between two salon appointments is something many of us know all too well. But there’s no need to panic: there’s a simple, quick trick to disguise roots in a matter of seconds. Hairdresser Myriam Keramane, founder of the brand Myriam.K, has shared her method for saving the day without leaving a single trace.
The pro move that changes everything
Rather than spraying a root touch-up spray directly onto her hair, Myriam Keramane prefers a far more precise approach. Her technique involves spritzing a little product onto a make-up brush, then gently sweeping it over the targeted areas.
This allows her to work with millimetre-perfect accuracy. It also avoids the unwanted stains on the forehead and temples that are a common problem with direct spray application.
The result is natural, with no smudging or stiff, cardboard-like effect. In short, this ultra-precise reflex guarantees an even finish that goes completely unnoticed.
Why the brush makes all the difference
The tool really does change the game. A make-up brush lets you control the amount of product and blend it precisely over the most visible grey hairs.
This way, the spray doesn’t deposit too much product over too wide an area. As a result, the finish stays subtle and natural, even up close.
“When it happens to me, I use a grey hair corrector spray. I apply it very lightly, comb my parting neatly, then blend with a brush so the result looks natural and even, with no stiff effect.”
An express touch-up in just a few seconds
With this method, a root touch-up spray and a make-up brush are all you need to blur roots in a flash. The hairdresser points out that it’s “super handy between colour appointments or when you need to head out quickly and want a clean result.”
What’s more, the technique is accessible to everyone. No special skills required: a few seconds and two accessories are all it takes to achieve a polished finish.
- Spritz the spray onto the brush, not directly onto the hair
- Comb your parting before applying the product
- Sweep gently over the areas where grey hairs are most visible
- Blend for a natural, even finish with no stiff effect
- Rinse out at your next shampoo to remove the touch-up
Roots disappear without leaving the slightest demarcation line. The result is instant and discreet, making it the ideal solution for everyday emergencies.
A temporary fix, not a substitute for colouring
This trick is not meant to replace a proper salon colour. It’s a temporary fix, practical and genuinely useful in a pinch.
The touch-up also washes out effortlessly at the next shampoo. No fuss, no residue: the hair fibre returns to its natural state after washing.
When to use this trick in everyday life
This method is perfect between colour appointments, when there’s no time to get back to the salon. That said, it’s not a long-term substitute for a colouring treatment.
It also works for any urgent situation: a professional meeting, an unexpected outing, or simply a day when you want to look your best. The most visible grey hairs disappear in just a few strokes.
What’s more, Myriam Keramane’s technique requires only two everyday accessories. A root touch-up spray and a make-up brush: that’s all you need to achieve a neat, polished result without setting foot in a salon.
In 2026, this trick continues to win people over with its simplicity and immediate effectiveness. Unruly grey hairs really don’t stand a chance.
