mixing hairdye with conditionair

Diluting dye with conditioner won't make the colour brighter.
Which dye was it and what colour were you aiming for?

the color was Violet by Directions
I was aiming for a bit brighter purple, but the pruple I got turned to be really really faded, and didnt catch most of my hair
so what does the conditionair do?

It dilutes the colour, makes it paler in cases of mid to pale colours. It will only make very dark colours brighter, but that's again, only because they're being diluted and made paler.

It dilutes the dye, which makes the colour lighter, more pastel. It can also be helpful in strongly pigmented dyes to prevent rub-off and bleeding and to make the dye go further.
Try the Violet undiluted (wash with shampoo, no conditioner before applying) it sounds like you just added too much conditioner.
If the colour isn't bright enough it is probably because your base is not light enough. For a vibrant violet shade you need platinum blonde as your base

thanks guys, i guess i did use too much conditionair.
ill try again tomorrow, with less conditionair, since i dont have enough purple color 🙁

I used to use Violet too, but I always mix it with Direction Cerise AND conditioner, I heard somewhere, that the colour in the bowl should be slightly darker that what you want on your hair  😉
