I can't take it anymore. My grays are out of control. They have taken over my whole head. My RE told me I could do highlights with a cap since day one, but ive been scared to do it. I went to Sallys beauty supply tonight & got a cap & dye & DH is going tom help me tomorrow. My OB also told me i could dye my whole head, but I thought I'd stay with my conservative RE. It will be ok right?
