If you are a fan of blonde coloring, you have probably adopted a routine haircare accordingly to avoid unwanted yellow reflections. Also, you have probably already heard of blue shampoos. Besides, you have probably asked yourself the following questions: “what are they for?, how to use them? what are their benefits?”
“Originally, blue shampoo was used to maintain grey hair and natural white” explains Emmanuel Pirenne, creative director ofEugène Perma 1919. “This yellowing product also made it possible to maintain the luminous and silver reflections of the White hair” he continues. And now ? “Over time, blue shampoo became increasingly loaded with colorings in order to further neutralize unwanted yellow (or orange) reflections” specifies the expert.
Anti-yellowing shampoo: why should you use a blue shampoo?
We call it “blue shampoo”, but in reality it is slightly purple. It is this color that neutralizes the yellow that we find in our hair over time. If the shampoo was simply composed of blue pigments, matte or even green reflections could appear (since: blue + yellow = green). To restore shine to your blonde color, it is therefore advisable to use a blue shampoo in your hair routine.

Based on the observation previously stated, it is therefore logical that frequent use of this product is not recommended. For what ? Because you risk obtaining matte or even gray reflections if your hair is too sensitized. “The right frequency depends on the number of shampoos you do per week. This is why I prefer to recommend using a blue shampoo every 3 classic shampoos” recommends the professional. Since blue shampoos are increasingly loaded with dyes, “We have to do pay attention to hair porosity“ alert Emmanuel Pirenne. “The more sensitive your hair is (therefore porous), the more it will absorb dyes: which could create unsightly reflections” he continues. You will easily find this type of product, many brands like L’Oréal, Olaplex, Dessange, Redken, Kérastase and Schwarzkopf offer blue shampoos. Now you know everything! Up to you !
Use: how to use blue shampoo?
To apply it in your hair, nothing could be simpler. This product is used just like a classic shampoo. Simply apply it to your roots, then gently massage your scalp. Then, rinse your hair thoroughly to remove all blue shampoo residue. You can then move on to styling, remembering to use a heat protectant if you use heated tools.
