Hi All--
path_of_one--I hope everything turns out well for you. I might add one more thought, and hope it is not belated. Watch out for the "overly-purply-based" reds. They will give you a maroonish look (which I have yet to witness occuring naturally in
anyone's hair) rather than a deep "Celtic"

auburn.
And thanks for the link, Brian--it spells out the basics of double-processing. Like I say, I hope you don't have to go that route since you have a fine texture.
Angel--yep, you are right about those vibrant colors--gotta take the hair up lighter than ferrari red if that's what your goal is.
InPeace,
InLove
