OLAPLEX has announced the launch of its latest products within the Bond Maintenance® system, designed specifically for fine hair.

The N°.4 Fine Bond Maintenance® Shampoo and N°.5 Fine Bond Maintenance® Conditioner are formulated to provide volume and strength without adding weight.
According to the well-known haircare brand, the new duo is clinically proven to deliver twice the volume and twice the strength, addressing a common challenge for fine hair, which often lacks body while also requiring softness and resilience. The system incorporates OLAPLEX’s patented Bond Building Technology™, which repairs damage while cleansing, hydrating, and protecting the hair. Clinical results also showed a 60 per cent reduction in breakage on bleached hair, and measurable repair, strengthening, and protection against future damage.
How it works
The formulations include flexible polymers for weightless lift, low molecular weight hyaluronic acid to hydrate while keeping hair manageable, and a hydra-balancing matrix to provide a clean, nourished feel without build-up. According to the company, this combination creates lasting fullness and shine while maintaining natural movement.
The beauty essentials
The N°.4 Fine Bond Maintenance® Shampoo is an ultra-light, volumising cleanser that removes build-up while strengthening and protecting fine hair. It is designed to gently cleanse without stripping, repair damaged strands, and boost root lift. Recommended usage involves applying to wet hair, lathering, and rinsing before following with conditioner.
The N°.5 Fine Bond Maintenance® Conditioner is described as a weightless formula that detangles, nourishes, and hydrates fine hair, leaving it soft, strong, and volumised. Directions suggest applying to mid-lengths and ends, leaving on for one to three minutes, and rinsing thoroughly.
