Dark chocolate, bronze, mahogany, cinnamon, copper, wine… There are many shades of black hair.
If you dye your hair brown, you’ve probably noticed that it looks better when you leave the salon. After a few weeks, the locks are noticed to lose their shine and copper and red tones start to appear on them, making the curls look dull.
Blue and green shampoos can solve this problem – don’t confuse them with tinted shampoos, which often end up on the same shelf.
How does blue and green shampoo work?
Do you remember the color chart that the teacher showed at school during drawing lessons? On this one, purple is opposed to yellow, blue is opposed to orange, and green is opposed to red. This is the principle of the action of shampoos, allowing you to maintain a clean shade of hair.
Blondes know what purple shampoo is – this product contains a pigment that neutralizes yellowness, restoring a clean, cool tone to the hair. Blue and green shampoos are exactly the same, except they’re designed for brunettes who have other issues to deal with.

When do you need blue shampoo and when do you need green shampoo?
It all depends on what tones appear on your hair: if orange or copper, then blue is needed, if red, then green. As celebrity hairstylist Nick Stenson explains, blue shampoo is generally best for light brown hair, green shampoo for dark to medium hair.
Do not think that these funds are needed only for those who dye their hair. Even if you don’t, you still run the risk of getting an unwanted tone – for example, it can show up due to sun exposure, which destroys the melanin pigment in the hair.
