Best Color-Safe Shampoo for Dyed Hair

The best color safe shampoo for dyed hair is one that has actually been measured slowing fade, and the clearest evidence we found points to Redken Acidic Color Gloss, the winner of the Good Housekeeping Institute's latest lab test. If you'd rather spend less, TRESemmé Revitalized Color came close to it in the same test, at a drugstore price.

Below are six picks, plus the wash habits that matter as much as the bottle you buy.

Quick picks

These are our picks for the best shampoo for colored hair, built mostly on Good Housekeeping's 2026 fade test.

What does a shampoo for color-treated hair actually do?

Water is the main thing that fades your color in the shower. Good Housekeeping's Beauty Lab says the biggest contributor to fading during a wash "is actually the water, not the shampoo," and cites hair scientist Dr. Trefor Evans's finding that dyed hair fades about the same with or without shampoo.

So a good shampoo for color-treated hair doesn't just skip harsh cleansers. It leaves something behind. GH Beauty Lab Director Sabina Wizemann says these formulas "use special conditioning agents that coat your hair's surface to prevent dye molecules from escaping." Some add UV filters too, because sunlight fades color.

Do you strictly need one? GH's answer is "Not necessarily, but it can help."

How GH measured fade

Reviews analyst Chiara Butler, a cosmetic chemist, narrowed 97 new products to a shortlist. She dyed 17 white human hair swatches red, washed each one 20 times with a shampoo and its matching conditioner to simulate a month, added 19 hours of UV light, then measured the color change with a lab camera. Then 76 home testers used the sets for two weeks.

That's why most of our picks come from that test: it's the only one we found that put numbers on fade.

Redken Acidic Color Gloss Sulfate-Free Shampoo

Best for: anyone with dyed hair who wants the strongest evidence and doesn't mind paying for it.

What we love

• It won Good Housekeeping's most recent test and "earned the best score for preventing hair color from fading over a month of simulated wear."
• GH's home testers said it made color look shinier, richer and more vibrant, and all of them agreed it left hair clean and soft.
• Redken says the shampoo and conditioner together give "color vibrancy for up to 32 washes," and that the acidic pH "helps seal the cuticle."
• It has no sodium lauryl or laureth sulfate.

Keep in mind

• GH's only con: it's pricey.
• The 32-wash claim is for the shampoo and the Acidic Color Gloss Conditioner used together, and GH tested them as a pair.

Key ingredients: amino acids (arginine, serine, glutamic acid), vitamin E, soybean oil, glycerin.

How to use: apply to wet hair, lather and rinse. Follow with the matching conditioner.

TRESemmé Revitalized Color Shampoo

Best for: a budget-friendly, big-bottle shampoo that still did well in a fade test.

What we love

• In GH's test it "performed almost as well as the winner at keeping color intact," and tied for best at conditioning.
• Every home tester agreed it lathered well, cleaned well and didn't irritate.
• TRESemmé says it's "infused with antioxidants" and offers heat protection "that starts in the shower" with the matching conditioner.

Keep in mind

• It contains sodium lauryl sulfate. GH points to it as proof that sulfate-free isn't the whole story (more on that below).
• Some GH testers found the 28 oz bottle bulky without a pump.

Key ingredients: green tea leaf extract, vitamin C, vitamin E, niacinamide, biotin, panthenol.

How to use: massage into your scalp and roots, squeeze the lather through your lengths, rinse well, then use TRESemmé Revitalized Color Conditioner.

IGK More Life Color Extending Gloss Shampoo

Best for: a sulfate-free, salon-brand option with test results to back it up.

What we love

• It came second in GH's test for stopping color from fading over a month.
• IGK says it preserves color for 15 washes and gives "2X high-shine," using color-locking polymers and UV protection. UV filters show up in the ingredient list.
• It's sulfate-free, vegan and cruelty-free, according to the brand.
• GH testers loved the scent; one called it "divine."

Keep in mind

• GH says it isn't as effective at conditioning, so dry or coarse hair will want a rich conditioner with it.
• GH lists it for oily or fine hair.

Key ingredients: color-locking polymers, squalane, argan oil, passionfruit seed oil, panthenol.

How to use: apply to wet hair, lather and rinse. Follow with the More Life Color Extending Gloss Conditioner.

Ceremonia Guava Color Protect & Damage Repair Shampoo

Best for: fine or oily color-treated hair that goes flat under heavy formulas.

What we love

• GH says it "helps hair color resist fading without weighing hair down," and it ranked highly for color protection and shine.
• Testers said their hair felt "very full" and "lively."
• Ceremonia calls it sulfate-free, vegan and over 90% naturally derived, made for damaged or color-treated hair.

Keep in mind

• It scored lowest for conditioning in GH's test, which is why GH suggests it for fine hair.
• It's fragranced with a guava scent.

Key ingredients: guava leaf and fruit extracts, aloe vera, glycerin, panthenol.

How to use: apply to wet hair, massage into your scalp and rinse. Ceremonia suggests the Guava Conditioner after.

Biolage Color Last Shampoo

Best for: dull-looking dyed hair when shine is the main goal.

What we love

• GH named it Best for Shine, with pros of "Adds shine," "Gentle formula" and "Leaves hair soft."
• Biolage says its low pH "prolongs color vibrancy," and that with the conditioner it helps color last "for up to 4 weeks" in a consumer test.
• It comes in a liter bottle, which makes it a sensible mid-range buy if you wash often.

Keep in mind

• GH's con: it isn't smoothing. One tester said her hair stayed frizzy.
• The listing we read doesn't clearly say whether it's sulfate-free.

Key ingredients: soybean oil, stearic acid.

How to use: apply to wet hair, lather, rinse thoroughly and follow with Color Last Conditioner.

L'Oréal Paris EverPure Moisture Shampoo

Best for: dry color-treated hair, if you want sulfate-free on a drugstore budget.

What we love

• An earlier edition of GH's guide called it "a GH Beauty Lab go-to" and said most women in a consumer study felt it kept their color looking "pure" after four weeks.
• L'Oréal says it's "especially gentle," made for dry hair, and keeps color pure "for up to 4 weeks with no weigh down."
• It's sulfate-free, with a rosemary scent.

Keep in mind

• That GH praise is from its 2022–2023 guide. It wasn't in GH's latest test.
• GH noted some reviewers with damaged hair found it drying.
• On amazon.com it's mostly sold as a two-pack or a shampoo and conditioner set.

Key ingredients: rosemary, gentle non-sulfate cleansers, a UV filter.

How to use: massage gently into wet hair until it lathers, rinse and follow with EverPure Moisture Conditioner.

How to choose the best shampoo for colored hair

1. Look for a number, not a vague promise. GH suggests choosing "specific number-based claims," like Redken's 32 washes or IGK's 15, over broad lines like "for colored hair."
2. Don't judge by sulfate-free alone. GH calls sulfate-driven fading "a myth" based on its testing, where sulfate-containing TRESemmé beat two sulfate-free formulas. Wella, a hair-color brand, still advises sulfate-free, saying sulfates can swell the cuticle "so dye molecules can escape." Our take: pick on fade results first, then go sulfate-free if your hair or scalp feels dry.
3. Match it to your hair, not just your color. Fine or oily hair: Ceremonia or IGK. Dry or coarse: L'Oréal EverPure Moisture, or a lighter shampoo with a rich conditioner.
4. Check for UV protection. Sun fades and dries dyed hair. The AAD says it's especially hard on dyed, bleached or permed hair and recommends a wide-brimmed hat.

Use the matching conditioner

The best shampoo and conditioner for colored hair is usually a matching pair. GH says brands' color claims "are usually based on washing hair with both products in a set," and it tests them that way. The AAD adds that if your hair is dry or curly, conditioner should go on the full length.

Wash habits that make color last

• Wait 48 hours after coloring. Wella recommends at least 48 hours so "the cuticle has time to close."
• Turn the water down. Wella says too-hot water can open the cuticle and let pigment out; lather with lukewarm water.
• Wash a little less. "The more often you wash your hair, the faster your shade will fade," Wella says. Dry shampoo can bridge a day.
• Shampoo your scalp, not your ends. The AAD says to apply shampoo to your scalp "instead of the entire length of your hair."

FAQs

Do you need a sulfate-free shampoo for colored hair?

Not necessarily. Good Housekeeping's lab found a sulfate shampoo (TRESemmé) protected color better than two sulfate-free ones, and it calls the sulfate-fading idea a myth. Wella, a hair-color brand, still recommends sulfate-free. If your hair feels dry, a sulfate-free option like IGK, Ceremonia or L'Oréal EverPure is a gentle choice.

Does color protecting shampoo really work?

It can help, though it won't stop fading. Water and sunlight do most of the damage. Color-protecting shampoos coat the hair with polymers or conditioning agents to slow dye loss, and the top sets in GH's test were the ones with the smallest color change after a month of simulated washes.

How long should I wait to wash my hair after coloring it?

Wella recommends at least 48 hours, so the cuticle has time to close around the new color. After that, wash with lukewarm water and stretch the time between washes where you can.

What's the best shampoo and conditioner for colored hair?

In GH's test, Redken Acidic Color Gloss Shampoo and Conditioner won, with TRESemmé Revitalized Color close behind as the budget pick. Use the matching conditioner, since brands' color claims and GH's results are both based on the pair.

Can a color-safe shampoo help with box dye too?

Yes. Color-safe shampoos are made for dyed hair however it was colored. The AAD suggests staying within three shades of your natural color, because lightening further takes more peroxide and does more damage. It also says to stop and see a dermatologist if box dye gives you a rash, swelling, burning or itching.

Pick one shampoo with real fade results, pair it with its conditioner, and turn the water down: that covers most of what keeps dyed hair looking fresh.
