Overview

OLAPLEX No.4 Curl Bond Shaper Hydrating Curl Shampoo is a gentle, deeply hydrating cleanser made specifically for coils, curls and waves. It washes away everyday buildup without stripping, helps bring out your natural curl pattern and locks moisture into the hair, so every wash day leaves curls softer, springier and easier to manage.

Powered by patented OLAPLEX Bond Shaper technology, it cleanses and cares for your curls in the same step, working from within the strand to support stronger-looking, healthier-looking curls over time. The silky creme-gel texture and cooling, fresh scent make every wash a pleasure. The 250ml size is the perfect everyday format - easy to keep in the shower and a great way to try the formula on your curls.

What It Does

• Defines curls, coils and waves - brings out your natural pattern at every porosity level
• Locks in moisture - a hydrating, non-stripping cleanse that keeps curls supple, not squeaky
• Helps control frizz - smooths the look of the hair for more defined, less fuzzy curls
• Cleanses without stripping - lifts product, oil and pollution while keeping hydration in
• Supports stronger-looking curls - patented Bond Shaper technology works inside the strand
• Used together with No.5 Curl Conditioner, OLAPLEX reports up to 50% less frizz even in humidity and curls that stay hydrated for days
• Gentle enough for every wash day; suitable for all curl types and textures

No.4 Curl vs the Original No.4 - Which Shampoo?

Both are gentle OLAPLEX cleansers, but they are built for different goals. Choose the one that matches your hair.

If you wear your hair curly and want definition with moisture, choose No.4 Curl. If you want an everyday cleanse for any hair type, the original No.4 Bond Maintenance Shampoo is the classic pick.

Bond Shaper Technology

No.4 Curl is built on patented OLAPLEX Bond Shaper technology, featuring the hero active sh-Oligopeptide-281. Rather than sitting on the surface, the technology works within the strand to help reinforce the look and feel of the hair's internal bonds, so curls look stronger, springier and more resilient wash after wash.

How it shapes and hydrates your curls

• Shapes and defines - helps curls, coils and waves fall into a more even, defined pattern from root to tip.
• Hydra-Define moisture - draws water into the hair and helps hold it there, so curls stay bouncy and look less dry through the day.
• Frizz control - smooths the look of the cuticle surface for less fuzz, even in humidity.

Who Is It For?

• All curl patterns - loose waves, springy ringlets and tight coils
• Every porosity level, on fine, medium or thick hair
• Curls that feel dry, look undefined or lose their shape quickly
• Colour-treated and chemically treated hair - the formula is gentle and colour-safe
• Anyone who washes often and wants a cleanser that defines and hydrates in one step
• Anyone who wants a gentle, daily-use curl shampoo in a convenient everyday size

Why Choose the 250ml Size?

• Perfect everyday size - easy to keep in the shower and simple to handle
• Great for trying No.4 Curl - a commit-free way to see how your curls respond
• Just the right amount - ideal for fine to medium hair or shorter lengths
• Easy to keep fresh - finish the bottle while it is at its best
• Want more washes? The 1000ml size is the better-value large format for long, thick hair, families and salons

How to Use

1. Apply a small amount of No.4 Curl to thoroughly wet hair.
2. Massage gently into the scalp and work the lather down through the lengths.
3. Rinse thoroughly. The lather is naturally lighter than a traditional sulfate shampoo - that is normal and not a sign it is working any less.
4. Follow with No.5 Curl Conditioner or an OLAPLEX mask to add slip, softness and lasting hydration.
5. Avoid direct contact with the eyes.

Gentle enough to use every wash day.

Build Your OLAPLEX Curl Routine

No.4 Curl is the cleansing step in your complete OLAPLEX curl routine. Combine it with a weekly bond treatment, the matching conditioner and your favourite stylers for defined, hydrated, frizz-controlled curls. For an intensive in-salon service, ask your stylist about the Bond Shaper Curl Rebuilding Treatment, a professional 3-step curl kit.

The Curl Transformation Routine

The go-to routine for curls that need moisture and definition. Start with No.3 Plus Complete Repair Treatment as your weekly pre-shampoo bond treatment, cleanse with No.4 Curl Hydrating Curl Shampoo, then follow with No.5 Curl Conditioner to seal in slip, softness and hydration.

Definition and Style

Shape and set your clean, conditioned curls. Define and control frizz with No.10 Bond Shaper Curl Defining Gel, then add a few drops of No.7 Bonding Oil for shine, smoothing and heat protection as the finishing touch.

What to Expect

• Curls that look more defined and sit more evenly from root to tip
• Hair that feels softer and stays hydrated, with less dry-looking fuzz
• Easier wet detangling thanks to the creme-gel slip, with less tug
