I currently use their ammonia free and regular intense black color on my hair. Can I use this over my existing color?

You must have pre-lightened hair to achieve maximum color vibrancy. Dying the purple on top of a dark hair color may give you subtle highlights but that isn't guaranteed.

I believe you could, but its just a temporary stain so it might not show up well over your existing color unless you were in bright light. Applying to pre-lightened hair is highly recommended.

I've done it once it gave me a dark violet color looked like grape soda. I would leave it in for about 25 min in the hair then wash out. I recommend doing a tiny section first then see a little result.

I have never tried that. In fact I have never completely washed it out. I suppose you could get it to wash out completely if you have time to wash your hair several times. Also, do not expect this to take you from a darker color to a lighter one. It doesn't get rid of the pigment in the hair the way permanent hair color does.

Not entirely sure... I don't color my hair, so I am hesitant to say yes. I would call a store like Ulta to ask the specialist there... Sorry I can't be of more help!

It does not have any PPD. It is by no means a "natural" product but it is one of the most healthiest coloring treatments of there. The closest you will get to black hair would be Elumen's NA@2. If you apply NA@2 to any hair color whether it is blond or brown, then it will be black. But remember that it is pure ash, so if you dye this on blond hair then it will fade to the base color of blue-green. Use NA@2 on dark brown to black hair, and you will be very happy with the results.

I used it on my hair, which I color. However, I do not like the product. It does not work as well as regular Nioxin. In fact i did not see any beneifts to using it at all and have since stopped the product.

Depending on your natural hair color, if you're trying to avoid brassiness ("red tone"), stick with ash or violet colors. The "N" in "7N" stands for neutral. That may work, but you may be better off with a "7A" or "7V." (The V isn't as common, but I know Ion has a color like that.) If you use the 7N and have red tones, this Brass Banisher product works fairly well. You can also try Wella Color Charm toner in T18. That may darken your color a little bit, but it will remove the red. You'll need to use a 20 developer with it. If your natural color is dark (brown or black), stick with the ashy colors. If you're already blonde and just want to go lighter, the neutral color may work ok. Wella Color Charm also has some extreme ash colors. I believe there is a 7AA color. I went from dark brown to light blonde. I like the intense ash colors, they really help to get rid of the "orange" that inevitably occurs when I dye my hair. But if your hair is dark, just using a 7 color probably isn't going to make it blonde. You'll probably have to bleach it first, then use the color, and probably add a toner. Unless you want to try the L'Oreal HiColor product. I, personally, haven't used that, but it's supposed to help you go from dark to light in one step with no brassiness.

YES!! I use the colorless one so it does not interfere with my colored hair...I do it myself at home. brings shine and volume and movement to my hair especially to the ends since I only color the roots but not the ends that frequently, so this is a nice option. I love it.

As I know, you can not dye your hair with chemical hair color for a hair you have dyed with henna. It is not because of safety. The reason is, your hair won't get that color. The problem with henna is, you won't be able to use chemical hair color over it. It is a permanent color. You may want to wait until your hair grow and use the chemical color for the hair you've not dyed with henna. Hope this helps.

Yes - however the shampoo/color makes your hair jet black - no other color available

Yes it can. It is similar to protein based deposit only colors like jazzing or cellophane. It's not really designed to be used with that kind of color...it would be redundant. But if for some reason you really want to you can. This product is for use with permanent color. It fills in porous areas to make hair stronger and more receptive to dye (the color will take more evenly and last longer if the filler is applied before coloring). If it is used after coloring it can be used as a toner (red to neutralize green, platinum which is blue based - to neutralize orange, red and yellow in light brown to white blond hair. There's even gold to enhance yellow in blond that is too pale or Burgundy for deep reds or dark browns that are too ashy. If you buy filler to match the color of your hair, it can be used to enhance or refresh existing color. A color wheel would help you to identify which colors to use for a desired effect. The protein in this product is great for counter acting damage from dye and styling. There is even a clear, it's called neutral to be used strictly for filling in porosity and strengthening hair before and after coloring.

I am sorry. I don't have color treated hair and I'm not a person in authority to say yes or no. I suggest you consult your hair dresser.

I don't know any reason why you couldn't. Naturtint is permanent hair color and should cover anything done previously.

You can use whatever you wish. Just keep in mind that the lower you go, the less color will show. Ex: if you use a 40 developer, your color will be vibrant and pop. If you use a 20 developer, your color will be lightly vibrant and suttle. Also, the longer you keep it on the hair, the more color you get. Ps: don't exceed over 1hr. I honestly wouldn't even go over that. Hope this helps

I did have a black dye on my hair and it didn't affect it in any way. But that was my personal experience, I cannot say how it would be for somebody else.

No, its not suitable for dark hair colors. It only works for butter blonde hair

I used the light brown from the Henna Guys over my red henna hair and it turned out black. The colors are misrepresented. There is too much indigo powder in the browns and your hair will be black and there is no way to remove it. I tried Prell, Head and Shoulders shampoo, which are very harsh and usually strip color from hair. I applied 100% pure henna 3 days apart for 4 hours each time and finally noticed a tiny reddish tone. Customer service rep told me the colored packets like light brown and medium brown which I also ordered should never be used over henna hair and it was my mistake. They advised me to go to a salon or wait for it to grow out; hardly solutions to the problem.

You would probably need to use a 20 volume. If your hair is light and you are trying to go black, unless you do something called "shrimping" which is to take it down to a darker color in 2 steps, your hair could very well turn green. Also, if you are older, black is going to make every wrinkle you have pop out. Unless you are willing to experiment, your best bet is to go to a salon and have a professional advise you and do it for you. Although this developer will work with other brands, it is from Germany and they specialize in blond colors.
