will this show up on black hair?

Unfortunately, it does not show as a color on black hair, but if you have highlights, it will. It does, however give ALL hair color a lustrous sheen, including black hair. There used to be a 'clear' version, suitable for dark hair, not sure if it still available. The colored ones, especially the red tends to come off on your clothes, so be careful, and do not wear white after applying, maybe after the first washing it will stop coming off, and will run in a pool too, before the first washing.

Yes - unless you're trying to go blonde, or bright red. Being allergic to permanent hair colors, the cellophanes give me the opportunity to mask the incoming gray in my deep chestnut-colored hair. However, as I also mix the Deep Brunette Cellophane (which, like my own color is almost black) with some of the Gold Red for highlights. First time I did this, I was just happy having more shine and not seeing any gray in my roots. However, in brighter lights (like sunshine) it REALLY looks spectacular - even my hairdresser wanted to know what I'd discovered! Hope this helps you.

It's going to be more vivid, like it would appear on bleached hair. You can find pictures of most of the colors on real hair if you Google them. Your hair will look like the more vibrant photos.

It would only be visible in the sunlight. Even with bleaching my hair, it's pretty dark and not at first noticeable. I have to mix it with a magenta shade to truly get it to look like the picture after bleaching my dark brown hair.

You will mix it with your hair color. You have 20 applications with the box displayed use only one application. You hair will appear darker and richer. I mix mine with black hair coloring.

Yes it will but its like a black powder It will wash out easily. That's the only thing about this is that if you bump your head or scratch it will come off. So be aware of that. I recommend a heavy hair spray to help keep it in tact.

Having color show up on black hair is never a guarantee. If you used a color like Ruby Red or Candy Apple you will most likey end up with a shine of dark red in any natural highlights of your hair.

No it will be very visible. It will be the color of the powder that you need to use; either black or gray.

Unfortunately no, but really no color will if you want it true to swatch you have to bleach dark hair. If you're bleach-shy this will look like a blue tint on dark hair that's only noticeable in direct light.

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.

Black color won't affect how foundation appears.If anything, you can see how much foundation you put on black sponge better than the pink one.

Hi Dear, I have black hair and have bought and used this produce, it is awesome but to answer your question I am not sure if this is for blond hair, because I do remember when I was searching for mine the one for blond hair was stating it on the bottle, so I don't think this is for blond hair because it dose not say that on the bottle. Good luck! 

I bought two different wigs for my niece. One was black but not nearly as wavy as it showed. The other turned out to be black & red. I THINK this is the second of those two.

I do not have black hair but my hair was extremely damaged and it works very well for me. I would recommend it

Since it's red, it will fade quickly. Red always does fade fast no matter if you use a color protection shampoo or any other sort of color treatment/protection hair color. I always shampoo and rinse with cold water to help prevent fading, and the upkeep is ridiculous because of how fast it fades. I used this protect when I had dark brown hair, and had to dye it twice to achieve the shade of red that I wanted.. So perhaps dyeing it on black hair may not be a good idea, and I definitely would not bleach your hair beforehand considering this lightens before the dye sticks. Hope this helps!

For best results you should bleach the hair first, the lighter the blonde of hair you start with the more vibrant and pigmented your results will be. If you use this product on dark hair it will most likely not show up.

it wont be a dramatic change. will look like a red rinse on black hair with highlights in the sun.
