Can I mix two boxed dyes in this manner?

I want to mix two boxed dyes by using one of the developer bottles. I was planning to simply eyeball 3/4 of the colorant of one...pour it into the developer, and then 1/4 of the other, pour it in...and shake it up.

Some cursory online reading about this has led me to believe it shouldn't be that simple, but it's not quite clear why.

    Box dyes aren't intended for mixing. This is why they are packaged like they are.

    If you want to mix your own colour you should buy the type of dyes and developer professionals use with the appropriate mixing bowel and spatula.

    Here's a thread from another forum where people who like the results of mixing boxed dyes are sharing about it. Maybe what looks good to them is not as good as using officially mix-friendly dyes though. I have no idea.

    I do it all the time with L'oreal Preference. Works for me. I'm pretty casual about the amounts too - sometimes 3/4 and 1/4, sometimes half and half, etc. I even save the leftover amounts and use them the next time.

    I guess it never occurred to me that it couldn't be done that way.

    I use L'Oreal Preference. I can't vouch for any other brand or version of L'oreal. Maybe try it once and see if you like the results. :profileleft:

    I would watch out for incompatibilities in the pigment chemicals. Have you ever tried to mix 2 water-based paints together only to get a non-homogenous mess that kind of curdles? It's not always the carrier base, but also pigment incompatibility. I am definitely not an expert, but I would be cautious. Call the manufacturer and ask for guidance.

    I have a friend that routinely does 50/50 between two colors and my mom used to do it too.

    ETA: I wouldn't because I think it's hard enough to tell what color your hair will turn out from a box dye, but that is just me. Like I said I've sure seen it done a lot. (Same brand of course, never between two brands.)

    What if you do it on hair you've already shed, from your shower or a comb (if you use one)? That's what's advised for henna.

    Yes, you can do this.

    1. Make sure you stick with the same brand
    2. Make sure you understand what base color the colors use because some things cancel each other out. People don't advise mixing box dye because it's sometimes difficult to tell from the labeling what the base is and the result can be unpredictable if you're not sure.
