Thank you Lynn for the quick reply.
After I posted that I actually got out the highlighting kit that I had bought along with the permanent color (I was going to use it a few days after dyeing my hair). I just did a test strand and within 5 mins it was majorly lighter!! This excited me because I feel like maybe I can go ahead and give myself highlights, even though I'll have some what of a skunk look, but anything is better than the gray!! I would love to just put this all over my head, but I'm afraid it'll burn my hair/head without the cap. What do you suggest? Also, can you tell me why is the highlighting kit taking but the color isn't??
I would like to highlight my hair this afternoon or this evening so I have a couple of days to get used to it before we go out this weekend.
