I'm menopausal. I've always self-dyed a golden blonde. Want to cover gray roots with caramel color. Help?

Hair dry from menopause and becoming straight and loosing curl; would like to get richer undertones and lose the all one color look. Have always used over the counter haircolor like Nice N Easy, etc. Usually just blow dry hair and then set with Caruso steam setter every 3/4 days. Would like a soft, wavy no fuss hair style...any suggestions much appreciated.
