This is a review from Amazon.com about product:
Moroccanoil Blonde Perfecting Purple Shampoo, 33.8 Fl Oz

After trying soooooo many purple shampoos, this is IT! I have purchased it multiple times. I leave it in for about 5 minutes while I shower. It lathers up really well, and gives you that whiter look. Be sure to mix it in good, and wash it all out. I use it once every few weeks. It lasts. I've never had a bottle leak either.
Shampoo Basics & Tips
What is Purple Shampoo?
Purple shampoo is a toning product for blonde, silver, or highlighted hair. Its violet pigments counteract brassy yellow or orange tones caused by sun exposure, chlorine, or fading hair color. Unlike regular shampoos, it deposits temporary color to neutralize unwanted warmth.
How Brassiness Neutralization Works
Brassiness occurs when underlying warm pigments in lightened hair oxidize. Purple shampoo uses color theory: violet sits opposite yellow on the color wheel, canceling out brassiness. For best results, apply to damp hair, leave for 3-5 minutes (per review), and rinse thoroughly to avoid uneven tones.
Why Lathering Matters
Rich lather (as mentioned) ensures even pigment distribution. Foaming agents like sulfates or gentle alternatives create bubbles that lift dirt while spreading violet dye uniformly. Poor lathering leads to patchy toning—always emulsify with water before application.
Optimal Usage Frequency
Use purple shampoo once weekly or bi-weekly (as noted). Overuse can cause purple buildup or dryness due to high pigment concentration. For damaged hair, follow with a moisturizing conditioner. Adjust frequency based on hair porosity—porous hair absorbs toner faster.
Leak-Proof Packaging Importance
Quality bottles with secure seals (like the reviewed product) prevent spills, preserve formula integrity, and reduce waste. Look for airless pumps or silicone-sealed caps, especially for travel.
Common Purple Shampoo FAQs
Can it work on dark hair? No—it's designed for light shades (level 8+). On brunette hair, it may leave a faint violet tint.
Does it damage hair? Not if used correctly. Avoid overuse and pair with hydrating masks.
Why rinse thoroughly? Residual pigments can stain light hair or scalp. Rinse until water runs clear.
How long do results last? Brightness typically fades in 3-7 washes. Maintain with monthly toning sessions.
