Just dyed my hair platinum… YELLOW?
This is how to tone things down a notch without all the chemicals and harm of dying it again, GO BLUE!
Just take an ordinary, super-moisturizing conditioner
(I know, totally not organic but all I had within my vicinity was a dollarama). So for future-organic reference, try purchasing a lavender based organic conditioner with LOTS of moisturizing capabilities coconut, argan, jojoba, etc.
Take a normal handful amount of conditioner, then mix the conditioner with 2 drops blue food coloring, 1 drop green coloring, and 1 drop red food coloring. The blue hue will neutralize the yellow tones in your hair!
Put into your wet hair like a normal conditioner and let it sit for a few minutes, then rinse it out.
I just started doing this and can already see a slight difference. Try using a strand test (when you experiment on a small portion of your hair instead of the whole head) to see how your results can vary!
