Olaplex No.4FINE and No.5FINE Shampoo and Conditioner Set

Designed specifically for fine, flat, and easily weighed down hair, the Olaplex No.4FINE and No.5FINE Shampoo and Conditioner Set combines lightweight hydration with advanced bond repair technology to help strengthen damaged strands while boosting softness, shine, and volume. Powered by patented OLAPLEX Bond Building Technology™, this salon inspired duo helps repair everyday hair damage without leaving residue or heaviness. 

Unlike the original richer Olaplex formulas, the No.4FINE and No.5FINE system was specially reformulated for fine to medium hair textures that need repair and hydration without losing body or movement. The lightweight formulas help cleanse, strengthen, smooth, and detangle while maintaining lift at the roots and soft bounce throughout the lengths.

Clinical claims shared by Olaplex report that the system helps double visible volume and strength while reducing breakage by up to 60% when used together. The sulfate free, silicone free formulas are also vegan, color safe, and suitable for chemically treated hair.

Why You’ll Love It

Unlike many volumising shampoos that can leave hair dry or tangled, the No.4FINE and No.5FINE system balances lightweight hydration with bond repair to help fine hair feel fuller while remaining soft and manageable.

Beauty reviewers with fine and oily prone hair especially praised how clean, airy, and bouncy their hair felt after use. One reviewer shared that the duo left hair “clean, soft, and fresh for longer between washes” while still improving shine and manageability.

Editors at The Independent also noted noticeable improvements in volume and thickness after just one wash, describing the hair as “light and fluffy” with enhanced bounce at the roots.
