I went red last year I was able to achieve pretty red colors without bleach. I've used john Frieda precision foam in burgundy, garnier olia in intense red, and garnier nutrisse foam in dark intense red for dark hair. All of these worked great and my hair was brown with highlights before I started dying. It also depend on how your hair takes to color.
3c/4a I Think. Trying to grow long, strong, beautiful curls.
