What brand of semi permanent hair coloring, really covers gray hair?

Loreal...because we're worth it. I've been using it for years. I just switched from "Preference" to their new line "Natural Match". Works great.

I like HennaPlus products. Still, keep in mind that semi-perms are suitable for only up to 25% gray hair. If you're further gone, you'll have to go permanent.

What brand of semi permanent hair coloring, really covers gray hair?

the whole idea with semi colors is to NOT cover completely; hence, the lower volume developer.

it's not as damaging to the hair because of the low volume developer. and low volume developer cannot cover the gray. it will BLEND it in.

if you are up to 20% gray then a 20 volume developer is needed. if you are up to 40% gray, then AT LEAST a 30 - 35 volume developer is needed. the higher the developer the more damaging to the hair it is.

did this answer the question? too much info? sorry.
