TOP PICKS
IGK BLONDE POP Purple Toning Shampoo
Best for: Bright, glossy blonde with a clean finish
Why We Love It
IGK Blonde Pop stands out for its high-intensity violet pigments that quickly neutralize yellow and brassy tones, leaving blonde hair noticeably brighter after just one wash. Unlike many toning shampoos that can leave hair feeling dry or over-processed, this formula maintains softness and shine. It refreshes color without dulling it, giving hair a clean, glossy finish that looks salon-fresh.
Lightweight and shine-boosting, it enhances brightness without buildup, making hair feel soft, smooth, and revitalized.
Worth Noting
The violet pigments are highly concentrated, so leaving it on too long may result in temporary over-toning on very porous hair.
Recommended Use
1–2 times per week ｜ Scent: Light, fresh ｜ Sulfate-Free: Yes ｜ Size: 8.5 oz
dpHUE Cool Blonde Shampoo
Best for: Sensitive scalps & clean beauty lovers
Why We Love It
dpHUE Cool Blonde Shampoo delivers effective toning while remaining gentle on the scalp. Ideal for those prone to irritation, this formula brightens blonde hair without stripping moisture or depositing too much pigment. Hair looks refreshed and luminous, never dull or overly purple.
It’s thoughtfully formulated for color-treated hair and leaves strands soft, smooth, and balanced after each wash.
Worth Noting
Because it’s designed to be gentle, those with very strong brassiness may need to leave it on slightly longer for more dramatic toning.
Recommended Use
1–2 times per week ｜ Scent: Light, clean ｜ Sulfate-Free: Yes (SLS & SLES-free) ｜ Size: 8.5 oz
Better Not Younger Silver Lining Purple Shampoo
Best for: White & gray hair
Why We Love It
Specifically formulated for mature hair, Silver Lining goes beyond toning to deliver volume, nourishment, and shine. Gray and white hair can often feel dry or flat, and this shampoo addresses those concerns while neutralizing yellow tones.
It helps boost body, improve shine, and support fuller-looking strands, leaving silver hair vibrant and healthy-looking instead of dull or brittle.
Worth Noting
Those with very fine hair may want to follow with a lightweight conditioner to avoid weighing strands down.
Recommended Use
1–2 times per week ｜ Scent: Soft, clean ｜ Sulfate-Free: Yes ｜ Size: 8 oz
Nexxus Blonde Assure Purple Shampoo
Best for: Protein-enriched strengthening
Why We Love It
Nexxus Blonde Assure combines toning power with keratin protein care, making it a great choice for blonde hair that feels weak or damaged. It works to restore strength, smooth rough texture, and maintain bright, cool-toned color all in one step.
The salon-quality formula delivers noticeable softness and resilience at a more accessible price point.
Worth Noting
Because it contains protein, those with protein-sensitive hair may prefer alternating with a more moisturizing formula.
Recommended Use
Once weekly or as needed ｜ Scent: Fresh salon scent ｜ Sulfate-Free: No ｜ Size: 13.5 oz
Olaplex No. 4P Blonde Enhancer Purple Toning Shampoo
Best Overall for Repair + Toning
Why We Love It
Olaplex No. 4P stands out for combining powerful toning with bond-building repair technology. Rather than simply masking brassiness, it works to strengthen and repair damaged hair bonds while brightening blonde, platinum, silver, or highlighted hair.
Highly concentrated purple pigments provide deep brass correction without leaving an unwanted purple cast, and hair feels smoother, stronger, and healthier with continued use. A little goes a long way, making the bottle last longer than expected.
Worth Noting
The formula has a thicker consistency and doesn’t create a heavy lather, but it still distributes evenly and cleans effectively.
Recommended Use
1–2 times per week ｜ Scent: Subtly sweet fresh citrus ｜ Sulfate-Free: Yes ｜ Size: 8.5 oz
FAQ
1. What does purple shampoo do for blonde hair?
Purple shampoo neutralizes brassy, yellow, or orange tones in blonde, silver, gray, or highlighted hair. The purple pigments counteract warm tones on the color wheel, helping your blonde stay bright and cool between salon visits.
2. How often should I use purple shampoo?
It depends on your hair and how warm your tones are:
Light blonde or white hair: 1–2 times a week
Brassy or highlighted hair: 2–3 times a week
Gray hair: As needed
Tip: Overuse can make hair look slightly lavender or dull — start with once per week and adjust.
3. Can I use purple shampoo on chemically treated hair?
Yes — most purple shampoos on the market are color‑safe and formulated for color‑treated hair. They cleanse gently while depositing toning pigments.
4. Do purple shampoos dry out hair?
Some can if they’re very clarifying. Choose formulas with moisturizing ingredients (like oils or conditioners) if your hair is dry or damaged. Always follow with a conditioner.
5. How long should I leave purple shampoo on?
Timing depends on how strong your brassiness is:
Mild toning: 1–2 minutes
Stronger toning: 3–5 minutes
Watch the color — if it’s taking on a purple tint, rinse sooner.
