Why Does My Hair Turn Red When I Dye It Purple?
When you dye your hair purple, the color contains a combination of blue and red pigments. Depending on your hair’s natural pigments, the purple dye may react with the red pigments, causing the hair to appear more red than purple. Additionally, if your hair is already damaged or porous, it may soak up the red pigments more easily, leading to a reddish hue.
