Can you use this on hair that was dyed about a year ago?

Check the instructions, but it shouldn't be a problem, especially since it was dyed over a year ago.

the short answer is yes- the effectiveness with depend heavily on how dark your hair is currently dyed, if you bleached it before the previous coloring then it'd be much safer to just let the current color fade before you try to bleach again

I used it and it looked like it took off most of the dye, but by the next day it was as dark as before I used it. I don't know what happened. Other people had the same problem as I did. Cj

My hair is color treated and I've used the product without any problems. The instructions did mention products to use if your hair is single processed or double processed.

Not that I'm aware of. It's kind of more like a toner. It says on the bottle it can be used on all kinds of hair colors. I have brown hair with highlights. It's just kind of revives the highlights but doesn't affect the rest of my hair.

I do not know. The company that produces it is very hard to contact or I'd suggest you ask them. I'd try it on a small, unobvious patch of hair and test it that way. Given that the reason the product works so well is the chemicals in it, I'd be leery of using it on color treated hair without testing.

You can use this on color treated hair, I do and I don't think it affects the lost of color any quicker than it normally does.

I must have used it past the 18 months. It still works but my hair color has been gradually turning darker than the 7NW color it was.

I believe so. I use it on my synthetic hair pieces when they start to look a little dry. Just a couple of pumps in my hand then gently squeeze it on the hair. Don't rub. Revives it like new.

It's been about a month since I used this, and the color has faded some, but I had a mess before - roots one color and the rest another (failed attempt to match didn't work). My hair, although lighter than when I first applied the dye, is still all one color. I'd think it will last another 2-3 weeks...

Color treated hair? I'm not sure, I don't see why it wouldn't but they have a website you may be able to ask them directly

You can use it daily until you achieve the color you want. It will fade after a few shampoos in any case. Great for in-between color emergencies. ..

I don't think so. It's made primarily for hair that has been damaged by heat or other styling. It's made my hair quite a bit stronger with regular use, but I don't know how it would react on colored hair.

I have used a couple of their products over the years. I think that would work. It doesn't work like regular hair dye where you are mixing chemicals and it develops. It is already in its final state. You are just letting it soak into your hair. For example, I have short hair, so I have used half a bottle and then used more in a few weeks. I will say though, it is not super long lasting, so you may just want to do it the full time because it will fade. The copper is my favorite! It gives a nice natural redhead looking tone, rather than the unnatural red you often see in dyes. Hope that helps!

No. In the instructions it says do not use if your hair has been color-treated. You'll damage your hair and end up with breakage.

Yes. My daughter, a beautician, started me using it when my hair was colored.

Hi Rita, my hair dresser suggested It's a 10 to me about 1 year ago and I have color treated hair. This is the best line of products I have used in years.
