Is this shampoo suitable for bleached or colour-treated hair?

This shampoo is explicitly designed for hair that feels rough after colouring or bleaching. The sulphate-free cleansing base removes oil and buildup without taking too much of the hair's own protective layer, which helps preserve colour vibrancy and reduces the "squeaky clean" feeling that can make porous, treated hair harder to comb. Argan oil — rich in unsaturated fatty acids and vitamin E — works on the outer cuticle to smooth the surface, so strands reflect light better and feel less coarse. Vitamin E adds antioxidant protection against stress from UV exposure and hot tools, both of which accelerate colour fade. For best results, follow with a conditioner or mask on mid-lengths and ends; if your scalp gets oily quickly, apply conditioner only from the ears down.
