Keeps my colour looking beautiful

I newly just got ashy blonde highlites on my dark brown hair and was scared that it would turn a funny colour even when using my colour protective shampoo and conditioner. My co worker suggested I start using a purple shampoo to keep the colour and this one happened to be on sale at Shoppers that day. I use it twice or three times a week instead of my regular shampoo and it’s kept my ashy blonde exactly the way it should be. It’s a great price! You’re paying half of what a purple shampoo would be at Sally’s or Trade Secrets and it works!
