Olaplex No.4 Fine Bond Maintenance® Shampoo is a lightweight, volumising shampoo specially formulated to cleanse, strengthen, and add body to fine hair without weighing it down. Powered by patented Olaplex Bond Building Technology™, this advanced formula repairs broken disulfide bonds while gently removing buildup that can flatten fine strands.
Designed to boost fullness and movement, the ultra-light lather leaves hair feeling clean, soft, and noticeably stronger with improved lift at the roots. Unlike traditional volumising shampoos, No.4 Fine maintains hydration and hair integrity, helping fine hair look healthier, thicker, and more resilient with every wash.
Ideal for fine, thin, or flat hair, including colour-treated and chemically processed hair, this shampoo delivers daily bond repair with weightless volume and shine.
