The 15 Best Blue Shampoos for Neutralizing Brassiness

Ombre, balayage, and classic highlights are great for adding dimension and lightening up brown hair. But unfortunately, bleach and other brightening treatments often go hand-in-hand with brassiness. Sound familiar? Before rushing back to the salon for an untimely touch-up, we urge you to consider an easier solution: blue shampoo.

The technology isn't new, though it used to be reserved only for blondes (in the form of purple washes). "Generally speaking, purple is the opposite of yellow, so it will freshen up and help to counteract unwanted yellow tones in blonde or gray hair," explains renowned session stylist and haircare developer Kevin Murphy.

While fair-haired folks often deal with a yellowing effect, brunettes are faced with an orangey hue. As such, blue shampoos are all about neutralizing the coppery hue with a cool-toned finish. Just bear in mind that "blue" is somewhat subjective. So while you'll find plenty of undeniably cobalt options, many lean toward indigo and even violet.

With this in mind, these are the best blue shampoos available today.

What to Look for in a Blue Shampoo

Blue vs. Purple

There are lots of blue and purple shampoos on the market. And while they achieve roughly the same outcome, blue is generally intended for brunettes, and purple is for blondes. However, some blue washes lean more toward indigo (and sometimes violet) than classic blue. In any case, you can pretty much count on a reduction in brassiness and an overall cooler-toned finish.

Frequency of Use

Most blue shampoos are intended to be used two or three times a week, though weekly use is often plenty. Be sure to read the directions carefully to avoid overusing it, as the blue pigments could leave your hair with a purple tint. "Sometimes purple or blue toning shampoos can over-tone and cause the hair to look dingy," adds celebrity hair colorist Guy Tang.

Nourishing Ingredients

Since bleach and other hair-lightening treatments are harsh on your hair, you'll also want to look for nourishing ingredients that help moisturize, strengthen, and repair brittle hair. We recommend options containing keratin, argan oil, avocado oil, amino acids, vitamin E, soybean oil, and green tea extract.

FAQ
  • What does blue shampoo do?

    Blue shampoo deposits blue-violet pigments onto the hair to cancel out unwanted brassiness, copper tints, orange tones, or redness. Similar to a salon gloss treatment, it coats chemically lightened hair to neutralize these warmer tones with a cool-toned hue.

  • How often should you use blue shampoo?

    According to Murphy, you can use blue shampoo as often as desired, but it ultimately depends on the state of your hair. "If your hair is porous and white, then you may need to use [it] only a few times a month, as you don't want a purple hue. If you have blonde [or] gray hair in good condition, you can use [it] as often as you like," he explains. "If in doubt, ask your stylist."

  • How do you apply blue shampoo?

    Apply blue shampoo to wet hair in the shower. Lather it around, focusing on the color-treated sections, and allow it to sit for three to five minutes. Then rinse it out and use a conditioner like you normally would. Some blue shampoos call for using gloves to avoid getting the color on your skin, but most will wash clean from your hands when you rinse your hair.
