Love this shampoo for taking out the brassy tones in my hair.
Be careful how long you leave it on for other wise it will stain it a purple tone, however if you want a temporary purple hue this works quite well at that.
Overall this is an amazing product that really does what it claims
This product was the most reliable out of the various products i used to get the orange pigments out of my hair when going blonde. It's quite strong so you only need to leave it in your hair for a short amount of time and you should be fine. It smells great and leaves your hair feeling good :)
Tips: Wash hands afterwards as there is a purple stain to your hands if left on your hands for too long. Or use gloves.
