I color and bleach my hair a lot and while I don't have greys yet (I think lol) I bought this shampoo in the hopes it would help cancel out the orange and yellow tones that was showing in my hair. I love how this cleanses, smells and feels while in the shower but I have noticed after the first few washes my orange start to fade, WHICH IS HUGE! I have used other "blonde" purple type shampoos and they always leave my hair stiff and dry but my hair felt soft and moisturized after using this and I am so happy. Definitely recommend to blondes along with anybody looking to get rid of unwanted tones. Need to get the bigger bottles for my clients in our salon soon!
