Olaplex Nº.4P Purple Toning Shampoo for Blonde Hair - Neutralizes Brassiness & Strengthens Damage, 250ml

Get rid of brassiness and bring out your blonde hair's true brightness with Olaplex Nº.4P Purple Toning Shampoo—your go-to solution for vibrant, healthy-looking locks.

• Neutralize yellow/orange undertones (brassiness) in blonde or gray hair to reveal brighter tones. The formula strengthens and repairs damage so each wash leaves your strands softer, more resilient, and full of life.
• This purple toning shampoo uses Olaplex's patented technology to target disulfide bonds in the hair shaft, effectively neutralizing brassiness at a molecular level. Unlike temporary dyes, it doesn't strip moisture—instead, it rebuilds the hair structure for long-lasting vibrancy.
• Perfect for anyone with blonde or color-treated hair (coily, curly, straight, wavy)—even those with heat-styled or chemically treated strands. It's vegan-friendly and dermatologist-tested, so gentle enough for daily use on sensitive scalps.
• Apply to wet hair after shampooing: lather thoroughly, let sit 1-3 minutes, then rinse. Use 2-3 times weekly; you'll see brighter tones and softer texture in just one wash!
• Certified free of sulfates, parabens, and formaldehyde—so it's safe for your hair and scalp. The unscented formula won't irritate sensitive skin while delivering consistent results.
• Receive a 250ml (8.5 fl oz) bottle of purple toning shampoo—designed to last through multiple washes while maintaining its effectiveness in neutralizing brassiness and strengthening hair.
