If you don’t dye your hair, you probably don’t know how common it is for color-treated hair to become brassy. In order to neutralize these brassy tones, shampoo companies have designed numerous products such as blue and purple shampoo. Here are the main differences between them.
|Blue Shampoo||Purple Shampoo|
|Formulated for people with brown hair||Designed for people with blonde and gray hair|
Purple shampoo is formulated to bust brassiness in color-treated hair. It is intended to be used by people with blonde and gray hair. It deposits purple pigments on light-colored hair to neutralize yellow tones.
Just like purple shampoo, blue shampoo is designed to neutralize brassy tones in dyed hair. But in this case, it is intended to be used by brunettes who have had their hair lightened or highlighted. Blue shampoo deposits blue pigments to neutralize red and orange hues.
Blue VS Purple Shampoo
Blue and purple shampoo are very similar products. They are both formulated to combat brassiness in color-treated hair – but each color is meant to be used by different customers. Blue shampoo is meant to neutralize red and orange tones in brown-colored hair, while purple shampoo is intended to counterbalance yellow tones in blonde and gray hair.
