I've been dyeing with Ion Color Brilliance - various purple shades (most recently, Radiant Orchid, and before that Fuschia).
The last two times I've dyed, the color came out of short hairs and the roots almost instantly. Like completely gone overnight, even if I didn't wash it at all. This last time I was extremely careful to work plenty of dye into the roots to make sure I wasn't missing them. Despite not having all that much hair, I spent well over an hour carefully working it into every part, then let it sit for two hours.
The attached pictures are half an hour after rinsing it out, and this morning (about a week later).
Process I've used:
Nonetheless the color is gone from the roots and short hairs between steps 7 and 8. Help?
My only guess so far is that The last two times I've dyed, i've been careful to make sure my hair wasn't washed. But my skin and hair are pretty oily - I wonder if it was oily enough close to my scalp to keep the dye from really getting to the hair. So I'm thinking I might try leaving it unwashed before I bleach, but washing it before I color. Thoughts?
Pictures: (1) 20 minutes after dying. You can already see the color didn't take well at the sides, near my ears. (2) a week later, color is completely gone from short hair and roots. Picture taken after a week, but it looked like this the first morning.
Yeah, this kind of dye needs to be used on completely clean, freshly washed and unconditioned hair! Right after bleaching is the ideal time in fact. You shouldn't be letting it go oily before using it, they're basically just conditioner with pigment in and anything that's on your hair will block it, not just oil. You're doing the exact opposite of what you should be doing in using it on slightly dirty hair.
You should be doing...
Leave it to get oily.
Bleach and rinse out. Shampoo if you want, but do not condition.
Use the dye.
Simple π
Okay, thanks. That's what I was beginning to suspect, even though at least a dozen guides online say "make sure not to wash your hair before dyeing it so you don't damage the hair or burn your scalp." (example - see point 10) It definitely seemed to me like that mattered for bleach, not dye, but I was trying to be good and follow the instructions.
That advice applies to oxidative dyes, not direct dyes like Ion color brilliance brights. There is no chemical reaction with direct dyes, no damage at all, they just coat your hair, so no need to protect your scalp from them.
Natural oil, and conditioners or leave in products will stop the dye from fully absorbing
Yeah, there's a rule of thumb you can follow.
If you mix two parts together or add peroxide, then they are oxidative dyes and you want oily hair. If it's just one part and you don't mix anything, it's a dye you apply to freshly washed, unconditioned hair. Always check the instructions though.
Y'all are great. That's better information than I'd gotten in fifty google searches, thanks!
I fail at Google fu, so i understand that one! But if you don't know what you're looking for, you don't know if what you find is actually correct anyway I guess π
