A leave-in treatment that works overtime to reverse the appearance of damaged hair. R.4 is a high-performance, bond-repair treatment powered by our RDS Bond complex to visibly restore hair health after just one use. Lightweight, fast-absorbing and non-greasy, it sinks into strands to support long-lasting bond strength, boost shine and deliver protection against colour fade, UV, and pollution.

This is your once-a-week damage rescue. For hair that’s been bleached, heat styled, over-brushed, or simply lived a good life R.4 repairs from the inside out, leaving your hair softer, smoother and with a shine so glossy it needs an ego check.
