I'm not sure if I've got the name exactly correct, but the RD is for Restore Doll & DH is for Dollyhair. They recently changed their name to Restore Doll Hair Color Reference which some of you might already know if you belong to the group. I asked the mod why she changed the name of the group & she gave me some information about the owner of Dollyhair that has negative connotations. I don't want to post it here because this isn't that kind of board, but if you want to know what she told me, you can email me at marnalevin@comcast.net for more info.
