Help with developer for at home coloring...

[xsnowwhite]

Hi everyone!
So recently my mom asked if I would fix her roots since her salon now charges through the roof prices and I told her i would. I know how to apply it and everything but my quesiton is what type of developer should I buy? From what I have been reading I should get 20 vol. developer but idk what brand. Should I get pure white or is that just for lightening hair? im confused

Heres some additional info:
I plan on buying at Sallys
I will use Miss Clairol dye
My mom has gray at the top we need to cover and we will be dying her hair a dark brown shade (roots only)

Thanks a bunch!​

i always used this stuff when i was dying my hair dark brown. i think you'll get the best colour deposit with a cream developer, and they're much easier (imho) to work with than liquid developers.

I'd just ask someone who works at Sally's. The girls who have helped me before are pretty knowledgeable. Is Miss Clairol a dye you can buy at Sally's? If so, it should say on the back of the box what you need as far as the developer.
