Cool blonde
Alright girls. I have a cool toned blonde. I will tell you: this works extremely well. Your hair will look blonde as hell. Here’s the thing though: Your hair will feel dry when you wash it out. So here’s your routine: Use this in your hair. Use a deep conditioning mask immediately afterwards. Your hair will look blonde and stunning. It works well. Just use that formula. Trust. I have been using this for nearly a year. Buy it.

Must have
Bright blonde every time! I highly recommend this purple shampoo. Even my coworkers noticed the difference and thought I dyed my hair again.
