Review on 👋 Yellow Goodbye Shampoo 1000ml by Schwarzkopf by Lisa Adams

I've used a few brands that people say will turn your hair purple if you leave it in for too long and those that let me shower don't it on my hair all the time, use it every day and it won't keep my blonde from turning yellow. Now I just used this product and washed it out immediately and after a few uses my blonde hair took on a deeper cool tone. It simply means it's powerful and works. I won't use it every day or leave it in the shower because I don't want dark purple/blue hair, but I'm so glad I found a product that works!
