Red is the family people talk themselves out of most often. Copper Glow is a natural copper with warm golden undertones and real luminosity through the lengths. Spiced Auburn is deeper and browner, with cinnamon and subtle copper running through a rich red-brown base.
Choose Copper Glow if you want red that reads as a genuine change, and Spiced Auburn if you want warmth without moving far from brunette. Red tones lift and fade faster than any other family with heat and washing, so read the care guide before you order rather than after.
