When you color your hair brown or blonde, you may not like the heat that comes through your hair color. If you're going for a cool look, it's important to have an at-home care routine that will help neutralize brassy tones and keep your color free of unwanted orange tones.
Purple shampoo vs blue shampoo
If this sounds like something you struggle with, learn more about what a blue shampoo is and how to use it properly to avoid having a green hair accident.
Blue shampoo is a firming shampoo that contains blue pigments. The latter are deposited on the hair with every wash, neutralizing any warm underlying pigments. If you have red or orange tones in your hair, blue toner will not give you a blue tint: because blue and orange are opposites on the color wheel, blue pigments provide corrective color, neutralize orange and keep your hair color cool.
Blue shampoo should be used on light brown and accentuated brown hair and is ideal for anyone who wants to maintain a perfect caramel, dirty blonde and ash brown color. It can also be used on natural brunettes, but the effect may not be as drastic.
