– 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.

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.

The idea of the brush on the bottle is genius as found it much easier to apply than normal brush and bowl, however formula a lot thinner due to this and have found not all greys have covered so unfortunately will be going back to clairol root touch up!

Very good product

I must admit I initially thought that this is a product you can use over and over again as a retouch whenever needed, rather than a one-off, so that was a bit disappointing. Nevertheless, for the price, it works a treat and the color lasts a good amount of time. Great shade too. Will definitely purchase again.
