8 Best Blue Shampoos to Eliminate Brassy Hair

Strong enough to brighten but gentle enough to not stain hands (or your hairline), this blue shampoo promises to deliver cooler toned strands after just one wash. "My hair is noticeably shiner and softer and indeed looks freshly colored after just one wash," one reviewer says.

Green tea extract, keratin and rosehip oil help keep hair strong and prevent breakage, while blue pigments neutralize orange tones. "Personally, my hair pulls red after bleaching," one reviewer says. "This shampoo literally turns red tones into nicer, softer caramel timbres in just one use."

Just one wash will banish brass from your hair. Vitamin E helps nourish and moisturize strands, while blue pigments infuse cool tones. "I use this shampoo ever other day, and it gives my hair a cooler tone," one reviewer says. "I have never been happier with my hair."

Unlike many blue shampoos, this formula creates a white lather, so you don't have to worry about the product staining your shower (or your hands). This formula is also great for anyone hoping to grow out their grays. "A big plus is how healthy my hair is now," one reviewer says. "I definitely recommend Blue Malva to anyone transitioning to natural silver hair."

Unlike traditional shampoos, this blue cleanser is designed to wash strands without lathering. Perfect for curly hair, it leaves strands shiny, fresh-looking and not brassy.  "I really wanted to find a shampoo that would keep all the natural curls intact along with helping them stay toned," one reviewer says. "My hair looks fresh and it smells amazing."

Spirulina, juniper berry and blue tansy all work in tandem with each other to keep hair hydrated, supple and strong. "It has a lovely fragrance and more foaming power than other clean shampoos I've tried," one reviewer says. "I do find that my brown hair is more radiant after a week of use."
