Olaplex No. 4P Blonde Enhancer Toning Shampoo

Olaplex No. 4P Blonde Enhancer Toning Shampoo (250ml): The Ultimate Bond-Building Brightener

Say goodbye to brassiness and hello to brilliant, healthy blonde with the Olaplex No. 4P Blonde Enhancer Toning Shampoo. This 250ml highly-concentrated purple shampoo is the first of its kind, merging powerful toning ability with the hair-repairing benefits of the signature Olaplex system. It’s the essential at-home maintenance product for all blonde, lightened, and grey hair.

At its core, No. 4P is infused with the patented OLAPLEX Bond Building Technology™ (Bis-Aminopropyl Diglycol Dimaleate). This revolutionary active ingredient works on a molecular level to repair damaged disulfide bonds within the hair structure. Because bleached and lightened hair is often the most compromised, this shampoo ensures that every time you tone your hair, you are simultaneously strengthening and repairing it, leaving strands visibly healthier, smoother, and less prone to breakage.

Customizable Toning and Repair:

The concentrated formula features potent violet pigments that instantly neutralize unwanted yellow and orange undertones, allowing you to customize your toning results. Clinical results show that the No. 4P makes hair 3 times brighter after a single use.

• Adjustable Intensity: For a subtle tone correction, leave the lather on for 1-3 minutes. For a more intense, neutralizing effect, leave on for up to 5 minutes.
• Deeply Hydrating: Unlike many harsh purple shampoos that can dry out hair, No. 4P is formulated with hydrating ingredients to cleanse, repair, and moisturize from root to tip.
• Reduces Breakage: By strengthening the fragile bonds of lightened hair, this shampoo has been shown to reduce breakage, making your color last longer and your hair feel stronger.

This luxurious, sulfate-free formula creates a rich lather that effectively cleanses while preserving your hair’s essential moisture and color vibrancy. The Olaplex No. 4P Blonde Enhancer Toning Shampoo is suitable for light to medium blonde, highlighted, and grey hair, whether natural or color-treated.

Use it 1-2 times per week, or as needed to combat brassiness between salon visits. For the best reparative and toning results, always follow with the Olaplex No. 5 Bond Maintenance Conditioner or the No. 8 Bond Intense Moisture Mask. It is 100% vegan, cruelty-free, and free of harsh chemicals like sulfates, parabens, and gluten.
