L'Oréal Paris Magic Retouch Instant Root Spray, Dark Brown 4. Delivers flawless coverage for grey regrowth in 3 sec. 75ml Dark Brown 4 shade provides a quick, easy natural-looking solution for roots.

Covers my greys perfectly- dark blond is true to colour. So easy to use. Bit expensive but looks good & wins on so many levels - will buy again.

Having used the spray I saw this and it seemed to be better and lasts longer. It was amazing! Came with a bottle with a brush at the end and it was so easy to use and apply! No faf no mess at all not even a drop on my ears or hairline .The instructions said to leave on for 10 mins and an extra 5 if grey is resistant but I left it on for 20. Easy to wash out and it covered all of my grey. Amazing product .

This has made life so much easier! Gone are the expensive trips to the hairdresser every couple of weeks. So easy to apply and developed in 10 minutes. The base colour 3 is a perfect match to the hairdressers 3. Hair looks healthy after use.

I use this every 3 weeks, and it works very well, the only downside is that there’s very little product, I have quite thin hair, but there’s only just enough to do my roots, just an extra 10% would make a big difference. The price is good from Amazon.

This product is awful. Sold as dark blonde but when used as instructed it’s almost black. Ruined my enjoyment an event I attended as it looked rediculous even after copious washings. Not recommended

My hair is going grey alarmingly fast and I don't find it easy to dye often (Due to my health) so these little root kits are wonderful to use in between. Really easy to use, it just brushes on over the roots and leave for 10 mins. Not a fan of the colour I had to get the darker one as the lighter option wasn't available so it doesn't look brilliant but I knew in advance it was the wrong shade,nothing against the product though. But I'll definitely be keeping my eye out for the lighter shade again.

This needs to be applied very quickly - 10 mins developing time. It took me longer than that to apply which meant it had been left on certain areas for longer and it stained my scalp. I used the light blond one and it did produce a nice shade but I didnt have time to apply to all roots. There isn’t sufficient product anyway. i think I’ll stick to the usual box type which i can leave on for about 40mins - my regrowth is white. it also expensive at £10.

Tried this for the first time today and WOW super impressed ! Easy to mix and apply, I especially liked the little brush as it applied to all the greys quickly as mess free. Saved me £75 getting it done professionally and looks just as good in my opinion ! I used the dark brown shade and it blends in with Garnier Coffee Roast Brown perfectly. Thanks Loreal !
