I have shade "Don't Touch" & it's the perfect crease sade & isn't warm. It's cool toned on me.
lots of YT videos on this however I'd say try to find someone with similar hair to yours and ++
Scrunch the product in and then don't touch until your hair is dry (this is very very hard, lol). +
My 8 y.o. DS pointed out that the front pieces of my hair ate noticeably darker...rop
I love them but they're also too warm (except for Don't Touch, which I use)
