Nº.4P Blonde Enhancer Purple Toning Shampoo for Brighter, Softer Hair

Nº.4P Blonde Enhancer Purple Toning Shampoo is an ultra-concentrated cleanser for blonde, gray, highlighted, natural, and color-treated hair. Violet toning agents help neutralize brassiness and yellow tones for a brighter-looking result, while a gentle blend of coconut oil-derived surfactants creates an easy lather. The formula cleanses from roots to ends and leaves hair feeling hydrated, softer, and stronger.

Use this purple shampoo weekly or as needed by distributing it between your palms, applying to wet hair, and lathering fully. Leave on for 1–3 minutes before rinsing well, or up to 5 minutes for more intense toning. The 250 mL full-size bottle provides up to 100 applications based on an average 2.5 mL application. It is sulfate-free, silicone-free, phthalate-free, phosphate-free, paraben-free, MIC/MIT-free, and protein-free, and is described as color safe, vegan, and suitable for chemically treated hair. Follow with Nº.5P Blonde Enhancer Purple Toning Conditioner for maximum toning results.
