Echosline shampoos wash hair well and last a really long time, because they are very concentrated, so it is enough to use very little shampoo. Echosline really thinks of all hair types. You can choose exactly the type of shampoo that is most suitable for your hair. Very popular is the S6 shampoo for downloading yellow reflections and also the S2 hydration shampoo. Very popular is the Seliar line, which contains quality argan oil, so it provides the hair with enough nutrition without unnecessarily burdening it. For long hair that needs smoothing, we definitely recommend the great Ki-power shampoo from Echoslin, which contains keratin. The hair will remain smooth and shiny.
