Does this shampoo help keep coloured hair from fading and looking dull?

Coloured hair often looks dull after washing with harsh shampoos because the cuticle — the outer scaly layer of each strand — stays raised. That raised cuticle lets pigment escape faster and scatters light, making the hair appear less shiny. This shampoo is formulated with mild surfactants that lift away sebum, styling residue and hard-water deposits without stripping the hair shaft. At the same time, conditioning agents settle on the cuticle and smooth it down, which helps the colour stay saturated for longer and improves shine.

If you regularly colour, bleach, or use heat styling, the cuticle is already more porous and vulnerable. A softer cleanser like this one can be a practical part of a routine to keep the colour from washing out quickly. For best results, follow with a balm or mask from the same series to add deeper conditioning, especially on the ends where pigment loss is most noticeable.
