Olaplex No.4 Curl Bond Shaper Hydrating Curl Shampoo

Description

Olaplex No.4 Curl is a hydrating shampoo for wavy, curly and coily hair. The silky creme-gel shampoo cleanses without stripping, strengthens instantly, defines curls and cuts frizz even in high humidity. It comes in two sizes, 250 ml and 1000 ml.

What is Olaplex No.4 Curl?

Olaplex No.4 Curl Bond Shaper Hydrating Curl Shampoo is a shampoo made specifically for curls. Curls are structurally unique: they have more bonds and more bends, so they break more easily. The shampoo delivers multi-action care that strengthens, defines and hydrates, and it targets the unique combination of needs of your hair, whatever your pattern.

The shampoo works on a molecular level. Patented 3D Bond Shaper Technology and Hydra-Define Technology give instant strength and defined curls, cut frizz in half and help protect length over time.

Who is it for?

Olaplex No.4 Curl suits all waves, curls and coils, and every porosity level. Colour-treated and chemically treated hair can use it too, because the formula is colour-safe. The product is trichologist approved, stylist and dermatologist tested, and vegan. You can find matching care in our hair conditioners category.

Technologies and oils

Patented 3D Bond Shaper Technology builds disulfide bonds from six points in multiple directions to repair, strengthen and define coils and curls. Hydra-Define Technology is a positively charged hyaluronic acid complex. It neutralises points of damage, seals the cuticle, locks in smoothing hydration and blocks frizz-forming humidity.

A natural oil blend of avocado and sunflower oils brings moisture, softness and definition.

3D Bond Shaper strengthens the internal structure of the hair and enhances natural curl shape and bounce. The shampoo helps natural patterns spring back more easily. Curls show up in more defined, more uniform groupings.

Texture and scent

The silky creme-gel gives the slip that keeps tangles away. The shampoo removes buildup without stripping, so hair feels light and clean between wash days. Used together with the Olaplex No.5 Curl conditioner, curls stay hydrated for up to seven days.

The scent is the Olaplex signature scent, reimagined. Crisp, invigorating sugared mint meets a bright burst of grapefruit zest and ginger, with a sophisticated, grounding base of crushed sage.

How to use

1. Apply the shampoo to wet hair.
2. Lather.
3. Rinse.
4. Follow with the Olaplex No.5 Curl conditioner or the Olaplex mask of your choice.

The shampoo is part of a curl routine. Your hair needs and goals decide which mask or conditioner follows.

Formula

The shampoo contains no protein, silicones, sulfates, SLS/SLES, phthalates, phosphates, MIC/MIT or parabens. That means no protein overload and no silicone buildup, and Olaplex No.4 Curl leaves curls light and clean.

A wash day for curls

Caring for curly hair is a calm and enjoyable ritual. The silky creme-gel glides softly through the hair and brings out every curl. Wash day becomes a small moment for yourself when the scent of mint, grapefruit and sage spreads through the shower. The fresh fragrance suits a morning when you want to start the day brightly, and an evening when you want to unwind after work.

Wavy, curly or coily, every pattern has its own character. Olaplex No.4 Curl celebrates that variety: the shampoo is made for all patterns and lets them shine. As a gift, the shampoo suits a good friend who loves her curls, especially with a matching conditioner added.

The shampoo is a good start to any curl routine, whether it is a simple three-step care or a fuller plan with Olaplex masks. Begin with cleansing and let your curls shine through the remaining steps. That way your curl routine grows step by step and stays consistent.
