Review (5/5): It worked for me!
I was excited to try this after I saw results from a friend using the blonde version of this product. I used it everyday for a week and then went back to my normal washing schedule. I could see results slowly. The top is my hair now, and the bottom is what it looked like before. I'm not sure if it's because of the red below my hair or the way the product works, but it has some copper tones to it. I don't mind though. I like it! I paired this with sun bum hair lightener spray.
Another thing I noticed is that this will leave a lot more residue on your scalp than other shampoos. I started washing my hair with apple cider vinegar shampoo right after using the shampoo and then moving on to the conditioner. I found it made my scalp less itchy and cleaner longer.
