Olaplex No.4P Blonde Enhancer Toning Shampoo

1. Overview

• Finish & Target: Vibrant, cool-toned hair finish engineered to neutralize brassiness, yellow undertones, and warm discoloration in blonde, bleached, grey, and silver hair.

• Texture & Format: Highly concentrated, deep-violet liquid shampoo housed in a squeeze bottle for precise dosing in the shower.

• Wear & Performance: Maximum toning power with up to 3x brighter results compared to standard purple shampoos; repairs broken disulfide bonds while cleansing without stripping moisture.

• Key Benefits: Combines patented bond-building technology with high-potency violet pigments to restore hair strength, repair structural damage, and maintain salon-fresh cool tones. Color-safe, sulfate-free, paraben-free, vegan, cruelty-free, and suitable for all hair textures.

2. Key Ingredients

• Bis-Aminopropyl Diglycol Dimaleate: Olaplex’s patented single-molecule active ingredient that seeks out broken disulfide bonds caused by bleaching, chemical processing, and heat styling, relinking them to restore internal hair strength and elasticity.

• High-Concentration Violet Pigments (CI 60730 / Ext. Violet 2): Highly saturated, direct-depositing colorants engineered to optically cancel yellow and brassy tones on the color wheel.

• Sodium Lauroyl Methyl Isethionate & Cocamidopropyl Betaine: Sulfate-free, gentle surfactant blend that produces a rich, creamy lather to cleanse hair and scalp without stripping natural lipids or drying out fragile blonde strands.

• Glycerin & Sodium PCA: Potent humectants that draw moisture deep into the hair shaft, countering the dry, coarse texture typical of bleached hair.

• Coco-Glucoside & Glycol Distearate: Plant-derived conditioning agents that enhance lather density, coat the hair shaft, and grant silkiness and high shine.

3. How to Use

1. Prep: Wet hair thoroughly. Gloves are recommended to prevent temporary staining of hands and nails due to high pigment density.

2. Apply: Dispense a quarter-sized amount into hands, lather thoroughly, and massage through wet hair from roots to ends.

3. Process: Leave on for 1–3 minutes for subtle toning, or up to 5 minutes for intense neutralization of persistent yellow tones.

4. Rinse & Condition: Rinse thoroughly with lukewarm water. Follow with Olaplex No.5 Bond Maintenance Conditioner or No.8 Bond Intense Moisture Mask for optimal hydration. Use 2–3 times per week or as needed to maintain cool tones.
