You've been great at answering my questions. Thanks so much. I'm trying to decide between regular medium brown and med. ash brown. Am I correct in saying the reg. med. brown has a reddish cast? Is it very minimal? I guess I'm looking for a warm tone. My hair is naturally a light to medium brown with some gray. Would the reg. med. brown be warmer than the ash med. brown? How might each affect gray? Also, is there any place on this site to take a look at the directions in the home kit? I'd like to familiarize myself before it arrives. Thanks bunches!
