Love this product! Lasts longer than other products. I only have to use it every 5 months other than other brands that would have been once a mo th wich can be very costly.

Works great for getting a few more days out of a colour. The application of it does take a bit of trial and error to get used to though. Spraying too much and you get spots, once you have figured that out it's no problem. You can definitely feel it in your hair but it's not too bad. No problems washing it out.. no leftover residue. Purchased a second time so that says something!

YAY !!! I finally bought this after changing my mind about 5 times !! I watched some ads which showed the actual real life application and bought it.

I am wanting to let my roots grow out so I can make a hair color change, and I want to see how much grey I do have, and if I can use my grey as a highlight maybe. By using this Root Cover Up Spray, I can get the exact look of a full color, but it washes out. I wash my hair every 3-4 days, so the spray lasts me a long time

It is very simple to apply and comes in Light to Medium Brown,Dark Brown,Black, Red,Light to Medium Blonde, and Dark Blonde. I use the Dark Brown and Red Mixed actually. The formula is ammonia free, peroxide free, and has no synthetic dyes. I think this product would be good to use if you were wanting to change your hair color, but wasn't totally sure what it would look like, you just spray over your hair, and decide yes or no, then just wash it out.. Good for teenage girls too, to have fun with hair color, but nothing permanent.

It also sprays quite similar to a Dry Shampoo, it isn't wet and tacky like I first thought. It doesn't drip or anything like that, It goes on very nicely and looks good. I find if you take a "bristled paddle brush" to brush your root to mid-strand area of your hair to blend it, it turns out the best.

I love it !!!

Officially one of my favourite products to use! Not that I've tried it, I feel like I can't live without it. It covers up my roots perfectly (I use the colour black). Not only does it blend in wonderfully, it actually makes my hair look thicker. Now it's not a thickening product, but when applied to my roots, it covers a bit of my scalp in the product, instantly making my hair look fuller. My only complaint is that it has a very matte finish, so if your hair is naturally very shiny, you do have to try to brush it out a bit to make it look more natural.

This stuff was disastrous for me, the Colorado didn't quite match and it was sticky and smelled yucky. I find that they don't have enough tones to choose from to accurately match your roots and I wish that it didn't rub off on everything. I put on my shirt after applying this product and the color transferred all over my shirt. I will not be buying this product again ever.....

This product worked so well on my brown hair. You have to be careful not to use too much at once. And hold the can about 8 inches from your hair. I usually get my hair coloured (to cover grey) every six weeks at the salon at $80 per visit. This product allows me to stretch my salon visits to ten weeks now!!! I love it!!

As a mom of five kids I'm starting to see the silver lining in my hair, literally, but with L'Oreal Root Cover up it's my little secret!I loved the ease of use of the product, it dried quickly and I was able to go about my day.
Likes:
The colour matched really well. I was actually fairly impressed with it.
It was easy to apply.
It was super quick to apply and to dry
I found it easy to comb through (other people complained it was “stiff” but I did not find it to be stiff at all.)
As you can see it covered up the grey really nicely, even though I did a quick/uneven job.
It feels natural. Doesn’t leave a film etc.
Dislikes:
The smell when applying it. I was in my bathroom and it made me a bit lightheaded. I would probably not have had this issue if I had been in a more ventilated area, or if the window was open. So I really suggest using somewhere nice and ventilated. I will say the smell doesn’t linger or anything, so I’m 99% sure ventilation was my issue.
If you get it on your skin your skin will take on the colour, though I found it came off easily. People have reported touching their hair has left their hands coloured, but I didn’t find that at all. I think it’s important to wait until it’s dry before touching.
I wished it lasted a bit longer than one wash. But the product did last until the wash, which is what it claimed to last.
I'm definitely going to keep it handy so that my grey streaks can remain my little secret, and would recommend it to other people.

So I was sceptical at first but I LOVE THIS PRODUCT!! As you can see in my picture it does exactly what it is supposed to do. It is very easily to apply and gives excellent coverage without having to use too much of the product. I am very happy with this temporary root cover up. I highly recommend this to anyone looking for a quick root touch up.
I do suggest wearing a towel as the fine mist may get onto your clothing.

I received a complimentary sample of L'Oreal Paris Root Cover Up and absolutely loved it. It's so easy to use and dries in minutes, so you're ready to go for any last minute event that you don't want your roots showing for. There's no "just coloured my hair" smell either, so no one will guess your secret. Any overspray simply wipes up with a damp cloth. I'll be looking for this product on the store shelves!! I tried the red and it completely blended with the rest of my hair colour. It comes in a variety of shades to blend with any hair colour. There's enough in the bottle for several applications, or you could colour all of your hair quickly and simply for a temporary boost!

Un produit idéal pour faire durer notre coloration. Ce produit s'applique bien, un peu comme un shampoing sec. Il part au lavage des cheveux. Je trouve que cela nous dépanne bien.
