OLAPLEX Blonde Enhancer Duo

OLAPLEX Nº.4P Blonde Enhancer Toning Shampoo 250ml and OLAPLEX Nº.5P Blonde Enhancer Toning Conditioner 250ml

OLAPLEX Blonde Enhancer Duo is a complete purple toning shampoo and conditioner routine for blonde, highlighted and grey hair that helps neutralise unwanted yellow and brassy tones while strengthening, hydrating and smoothing the hair.

The two formulas are specifically designed to work together. Nº.4P Blonde Enhancer Toning Shampoo cleanses while depositing violet toning pigments to brighten blonde and grey tones, while Nº.5P Blonde Enhancer Toning Conditioner continues the toning process while replenishing hydration, detangling and smoothing. OLAPLEX recommends using Nº.5P after Nº.4P for maximum toning and brightening results.

Neutralises brassiness – Violet toning pigments help counteract unwanted yellow and brassy tones for a cleaner, brighter-looking blonde.

Provides double toning action – Nº.4P begins the toning process during cleansing, while Nº.5P deposits tone-balancing pigment in areas where the shampoo may not fully deposit, helping create more even results.

Strengthens while toning – Both products contain OLAPLEX's Bis-Aminopropyl Diglycol Dimaleate and are designed to support stronger, more resilient hair.

Hydrates and softens – Nº.5P replenishes moisture while helping blonde and chemically treated hair feel softer and smoother.

Smooths and detangles – The conditioner instantly detangles and smooths the cuticle, helping reduce frizz and improve manageability.

Boosts shine – By balancing unwanted tones while conditioning the hair, the routine helps blonde and grey hair appear brighter, smoother and more luminous.

What Is It?

OLAPLEX Blonde Enhancer Duo is a two-step purple toning system designed to answer one of the biggest concerns with blonde, highlighted and grey hair:

How do you neutralise unwanted yellow tones without leaving already processed hair feeling dry and rough?

The system combines toning with OLAPLEX bond-building hair care.

OLAPLEX Nº.4P Blonde Enhancer Toning Shampoo provides the cleansing and initial toning stage, using violet pigment to neutralise unwanted yellow tones.

OLAPLEX Nº.5P Blonde Enhancer Toning Conditioner follows with additional toning while replenishing hydration, smoothing, detangling and strengthening.

OLAPLEX specifically recommends using the two together for maximum toning and brightening.

Together, the duo creates:

Cleanse → Neutralise → Tone → Hydrate → Strengthen → Brighten

OLAPLEX Nº.4P Blonde Enhancer Toning Shampoo 250ml

A highly concentrated purple toning shampoo created for blonde, lightened and grey hair.

It is particularly useful for:

Brassy blonde hair

Yellow tones

Bleached hair

Highlighted hair

OLAPLEX Nº.5P Blonde Enhancer Toning Conditioner 250ml

A highly concentrated purple toning conditioner designed to continue the toning process while delivering the moisture that blonde and chemically treated hair often needs.

Hydrate

Strengthen

Detangle

Improve softness

Enhance shine

OLAPLEX states that Nº.5P is suitable for natural and colour-treated blonde or grey hair and can be used across straight, wavy, curly and coily hair.

Step 1 OLAPLEX Nº.4P Blonde Enhancer Toning Shampoo

Apply to wet hair.

Lather thoroughly and distribute through areas where yellow or brassy tones are visible.

Allow the purple toning formula to work according to the product directions and desired toning level.

Rinse thoroughly.

Step 2 OLAPLEX Nº.5P Blonde Enhancer Toning Conditioner

Apply generously to clean, damp hair from roots to ends.

Leave for 1–3 minutes.

Rinse thoroughly.

OLAPLEX recommends using Nº.5P weekly or as needed and specifically recommends pairing it with Nº.4P for maximum toning results.

Because purple pigments can deposit progressively, follow the recommended timings rather than leaving the conditioner on indefinitely. OLAPLEX notes that longer application can increase violet pigment deposition.
