I honestly can't go out without using this shampoo from ANAZE—I'd feel embarrassed! Otherwise, my hair turns into that brassy yellow shade... Even the ash grey dye I did before stays looking fresh, enough to surprise my salon stylist. And when I keep using it on my bleached roots, they gradually shift to a grey tone too. Compared to other color-correcting shampoos, this one lathers up so well—almost like a regular shampoo. My hair is super thick and reaches my waist, but just two pumps are more than enough. If you notice any uneven color, just mix it with your usual shampoo and it evens out a lot. You don't need to leave it in—just lather as you normally would and rinse right away. Unlike some famous overseas brands, this one doesn't stain your nails at all after use, and even if you use it in the shower, it won't leave any color on your skin.
