Olaplex No.4P Blonde Enhancer Toning Shampoo 8.5 oz is a highly concentrated purple toning shampoo designed to neutralize unwanted yellow and brassy tones while cleansing and strengthening blonde, highlighted, gray, and lightened hair.

Formulated with concentrated violet pigments, No.4P helps maintain a brighter, cooler, more even-looking blonde between salon appointments. Olaplex's signature bond-building technology works alongside the toning pigments to support weakened hair and help improve the appearance of strands affected by bleaching, coloring, heat styling, and chemical processing.

Ideal for natural blondes, highlighted hair, balayage, platinum blonde, silver, gray, and pre-lightened hair, No.4P provides customizable toning—the longer it remains on the hair, the more intensive the toning effect.

What It Does

Olaplex No.4P Blonde Enhancer Toning Shampoo combines cleansing, toning, and bond-building care in one concentrated formula.

Its violet pigments help counteract unwanted yellow and brassy tones, resulting in a cooler and brighter-looking blonde.

At the same time, Olaplex's bond-building technology helps support the hair's internal structure, making No.4P particularly useful for blonde hair that has been compromised by bleaching, highlighting, coloring, or frequent heat styling.

How to Use

Apply Olaplex No.4P Blonde Enhancer Toning Shampoo to wet hair.

Work the shampoo into a rich lather, concentrating on areas where unwanted yellow or brassy tones are most noticeable.

Allow the shampoo to process for 1–3 minutes, then rinse thoroughly. For stronger toning, the product can be left on for up to 5 minutes, depending on the hair's condition and desired result.

Follow with Olaplex No.5 Bond Maintenance Conditioner or another appropriate Olaplex conditioning treatment.

Because No.4P contains concentrated violet pigments, begin with a shorter processing time on very porous, platinum, or heavily lightened hair, as these hair types may absorb toning pigments more quickly.
