Does it work on previously colored (dark) haïr?

I've colored my hair and then used the highlights with no problem. It is essentially a bleaching process and the bleach will cut through even previously dyed hair. Hope this helps!

I'm not a professional of course, but it worked on mine. Mine was previously colored a dark brown/red. I waited two months then highlighted

No. It does not work on blonde hair. It's also not great on dark, course hair. The best results are on dark fine/medium hair.

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 have white hair now. When I was younger I had dark hair. It works, whatever color.

It does works but not easily. It takes repeated applications on very grey hair. It also may appear reddish, unless left on a long time. You get best results with a fresh batch, mixed with a little indigo to darken.

You should be able to use it as is. My hair is a darker brown so it came out a deeper darker burgundy that what is shown here. if your hair is a medium blonde you should get the results shown on the picture. Mine also may be darker because I left it in overnight. The longer you leave it on, the darker/more developed the color will be. Good luck.

I believe you can use it on dark brown hair. I used it on Afro dark/gray hair and it gave me a perfect bleach.

Yes. This product works but only with continued use..it will darken back up if you stop using it.

Yes I have dark brown hair and it works. They only thing is you need to go over your hair a few times so it uses up more chalk

Not sure about that I have used it on darker hair and haven't had any coloring issues. It is very sticky and had a great hold and keeps through out the day. If you have more of it in one area it tends to make it shine a little bit.

My hair is dark, dark brown and I chose dark brown. Not sure what to tell you but it works for me. Hope this helps.

My hair is actually color treated! Light brown too. No it didn't darken my hair at all. I'm at the end of my bottle and since I've gotten it I've seen at least 2 inches of growth though, so I'm getting the roots re-colored soon. And no redness either. I just put a little bit on my head at night, wrap it up and keep it moving.

Blue black hair dye will not lighten your hair. If that is in fact the color you used. If your hair was previously dyed you need to remove existing dye before you color. .. try colorfix and then do a quick bleach cap to remove unwanted color and then re dye. If your hair is damaged just try and wait for it to fade. You cannot lighten existing dark hair color with other dyes...only bleach or color removers.

from what I've seen it does not effect color or color treated hair. it is the only product that I have used the is clearing up my scaly rough head. it take awhile but it does work, I treat two to three times a day with no color shift, but I am somewhat bald and silver gray, i does not yellow my hair as some have done before.

This is a hair lightening kit, yes. I have very dark brown hair and one application lifted my virgin hair to a near-platinum blonde and my previously-dyed hair to a slightly brassy blonde. It is very effective and one of the better products I have used for color lifting.

Yes, you can. My hair was still dyed, but I stopped dying it and started using GrayBan so I could let my gray grow out gradually. If you have dark hair, it won't completely restore the dark color, but it helps it to blend in more naturally and make you look less gray.

I think it is because i have colored hair and it have not done anything, excellent product. My hair was breaking after the first use i can see a big difference.
