Olaplex Nº.4 FINE Bond Maintenance Shampoo 250 mL — Volumizing, Strengthens Fine Hair

Olaplex Nº.4 FINE Bond Maintenance Shampoo is a lightweight, volumizing cleanser that strengthens and repairs fine hair while adding lift and lasting body without weighing strands down.

This shampoo was formulated for hair that needs both repair and volume. Instead of heavy conditioning agents that flatten fine textures, Olaplex Nº.4 FINE uses low‑weight hydrators and flexible polymers to remove buildup, bolster fragile bonds, and leave hair feeling clean, soft, and springy. Clinically tested alongside Olaplex Nº.5 FINE conditioner, it helps reduce breakage and enhances fullness after use.

How does this shampoo add volume without making fine hair greasy or heavy?

Olaplex Nº.4 FINE relies on a combination of flexible polymers and a hydra‑balancing system to lift at the roots while keeping mid-lengths and ends light. These ingredients support strand separation and body instead of coating hair with heavy oils.

• Flexible polymers provide root lift and structure.
• Low molecular weight hyaluronic acid hydrates without weight.
• Hydra‑Balancing Matrix cleanses buildup while preserving natural volume.

Will it repair damage from coloring, heat, or styling tools?

The formula is designed to target weakened hair bonds and reduce future breakage when used as part of the Nº.4 FINE + Nº.5 FINE routine. Clinical testing indicates a measurable reduction in breakage and improved strength on compromised hair.

• Bond‑preserving technology helps rebuild and protect strand integrity.
• Clinically proven to reduce breakage on bleached hair when paired with Nº.5 FINE.
• Safe for frequent cleansing after styling or salon services.

How should I use Olaplex Nº.4 FINE for best results on coily, curly, wavy, or straight hair?

Wet hair fully, then apply a small, concentrated amount to the scalp and massage to lift oils and buildup. Rinse thoroughly and follow with Nº.5 FINE Conditioner to maximize strength, softness, and lasting volume.

• Apply to scalp and roots for effective cleansing and lift.
• Rinse and use Nº.5 FINE to lock in repair and hydration.
• Adjust frequency based on your hair’s oiliness and styling routine.

What performance can I expect after regular use?

Regular use helps maintain cleaner, fuller-looking hair and reduces the visible effects of breakage caused by daily styling and chemical services. Users typically notice improved bounce, smoother texture, and a fuller silhouette without added residue.

• Clinically shown to double instant volume and maintain it all day.
• Helps detangle and smooth while keeping hair soft to the touch.
• Prevents future damage when used with the matching conditioner.

Who is this for? Olaplex Nº.4 FINE Bond Maintenance Shampoo is ideal for people with fine or fine‑medium hair textures—whether straight, wavy, curly, or coily—who want lightweight cleansing plus targeted bond support. It’s especially useful for hair that’s been lightened, heat‑styled, or frequently manipulated and needs a gentle formula that builds volume and resilience without heavy conditioning. For best outcomes, pair it with Olaplex Nº.5 FINE Bond Maintenance Conditioner.
