This is a review from Amazon.com about product:
Olaplex No. 4P Blonde Enhancer Purple Toning Shampoo, Repairs, Hydrates, & Brightens All Blonde, Lightened, & Grey Hair, 8.5 fl oz

This made such a difference for my white hair! It went from warm to bright white and looks better with my skin. I have gotten three compliments on my hair since I started using the shampoo this week! As other users have commented, it is strong and I swear that I see a hint of purple, but whatever... It looks great! Highly recommend. Worth the money.
Shampoo Basics & Tips
How Purple Shampoo Neutralizes Yellow Tones
Purple shampoo contains violet pigments that counteract yellow/brassy tones through color theory. The color wheel shows purple (opposite yellow) neutralizes warm undertones, creating cooler hair shades. This explains the reviewer's "bright white" transformation.
Why Strong Formulas Matter for Gray/White Hair
Mature hair tends to be more porous, absorbing pigments faster. A "strong" formula (higher dye concentration) ensures effective toning. However, the user's "hint of purple" comment suggests brief application time prevents over-toning.
Skin Tone Harmony Achieved
Cool-toned hair (bright white) complements cooler skin undertones, while warm hues clash. The shampoo helped the reviewer achieve color harmony, evidenced by increased compliments about their overall appearance.
Economic Value of Professional Results
Compared to salon toning treatments ($80+ per session), quality purple shampoo ($15-$30) offers similar results with weekly use. The "worth the money" endorsement reflects this cost-benefit analysis.
