Concealing roots between salon visit is a problem for so many of us. I used Root Erase, which I loved, but that has disappeared off the shelves. I got this product at Sephora at a 20% off sale. I would recommend you buy where you can try a tester. The colors are not true to the label description. I am medium brown but bought light brown. It is a perfect match. But, as others have written, much darker than a light brown. Results are instantaneous and last until next shampoo. In many ways, better than drippy color from a box all over the place. Also, it seems to give my hair more body even though I only use it on the part. I will definitely continue to use this.
I bought this ulta the other day because my I couldn't find my normal root concealer. I found it pretty expensive for the size of the bottle. I have light/medium brown highlighted hair and I bought he light brown spray and it was so dark it was more like a dark brown. It also made my roots sticky and if you touched my roots it would rub off. I returned it the next day and with the refund I just spent the money and paid to have my roots done.
This stuff is great. It matches my hair color (in light blonde), covers grays, and seems to stay put even when I rinse my hair and put conditioner in it (a necessity for us curly haired types who wash only once a week). I usually touch up my roots at 3 or 3 1/2 weeks and see my hairdresser every 5 or 6. I'm at 4 weeks and counting and I just don't feel the need. It's so much better than my previous product, color mark/touch back, which applied beautifully but wasn't quite the right color, and disappeared after a day or as soon as water touched my hair.)
The trick with application is to really try to hold it 6 to 8 inches away and spray lightly. Doing my hairline is more problematic: I use the comb that comes with color mark to protect the skin and spray it very lightly, again from far away. But I'm only covering my part and two tiny bits at my temple and ear. So far it's lasting well, although I'm always scared I'll turn around and discovered that I've touched up my towels!
Firstly let me say that I do not use this to cover grey hairs. I have extremely thin hair on the top of my head and I use this product to make my hair look fuller. It really works too, and my scalp is less visible whenever I use this (which is what I wanted). I do have a couple of issues with the product though, but it wouldn't really stop me from buying it again. The price is ridiculously high, I paid $37 for two tiny aerosol bottles which is way overpriced. The color I use is Dark Blonde even though my hair is light to medium red-brown. I read the reviews of this on QVC and almost all reviews said that the Light Brown color (which is the one I would have chosen) runs very dark, almost black. So the next shade up is the Dark Blonde. It is very slightly too light for my hair, but only slightly. If I spray a lot on then it is visible, but with a normal application the color difference is hardly noticeable. Once I have applied this, I brush my hair afterwards which seems to remove any harsh lines between where the product ends and where my hair color shows through. It really does last and is quite a pain to wash out. But saying that, I live in Florida where it is very humid and this does really stay put. I do use Joan Rivers Great Hair Day more than this spray though, just because it works out cheaper in the end (and the color is better) but this spray I have to say does look more natural with less product. The Joan Rivers powder I have to apply almost over my whole head in order for the thin areas to look fuller. With the spray I only need to add it to below my part because it is less dense than the powder application (if that makes sense). If this spray was made a whole lot cheaper, and the color range was expanded, then I would wear this all the time. As it is though, it does what I want it to and leaves me feeling less self conscious about my thin hair even if I can't afford to wear it all the time.
I have very light blonde hair and I never have the money to get my roots touched up when they are growing out soon enough at the salon. Here is my solution! This brande comes in every color ( i need platinum blonde) Just spray it on the roots and you have an instant highlight job. It lasts until your jnext shampoo---great for an event you have to go to, but no time or money for a salon! This is just so awesome!!!
