Definitely brightened my hair but it did stain my hands, will be using gloves next time.

This shampoo is amazing for people who dye their hair red - it’s a great go between for when it needs a dye. I use it about once a week but beware it does stain! 

This is Ok, it’s not as pigmented I was hoping for, I prefer the Wella one.

Stains the ski easily and makes very little difference to the hair

I have bright red hair, think London bus red, 6 weeks after colouring and using this once a week my hair is still as vibrant as ever. As anyone who colours their hair red will tell you its hard to keep that kind of colour in your hair, this stuff is amazing and I will keep buying this.
