How does this conditioner help protect colour-treated hair from fading?

Colour fading isn't only caused by washing — UV exposure, heat styling, and environmental oxidation break down colour molecules inside the hair shaft, making shades look flatter over time. This balsam addresses that in two ways. First, argan oil's fatty acids (mainly oleic and linoleic) coat and smooth the raised cuticle scales that make porous, coloured hair feel rough and lose moisture. A smoother cuticle reflects light better, so colour appears more vibrant. Second, the naturally occurring tocopherols (vitamin E forms) in argan oil, plus the added antioxidant botanical extract, help neutralise free radicals generated by sunlight and heat. This oxidative protection slows the chemical degradation of dye molecules. For best results, use it after every wash, concentrating on mid-lengths and ends where colour loss is most visible. If you blow-dry or use straighteners regularly, this step adds a protective layer before heat exposure. It won't replace a dedicated UV spray for prolonged sun, but it reduces daily oxidative load on coloured hair.
