I use this most days on my hair. I use it combined with either the Avocado and Calendula or the Wheat Proteins conditioner. For me, it's possibly the best shampoo/conditioner I have ever tried (with Michael DiCesare close second). It really does help my colour last, it cleans very gently and makes your hair feel all clean and swingy without any build up. Be aware though it doesn't always foam up as highly as other brands - if you want a high foam then shampoo twice with it...I only do that if my hair is particularly greasy. A 500ml pump will last me around about 8 months, the conditioner about 8-10 months.
MyPure offer samples of the shampoos if you want to try before committing - and some branches of Tesco now carry the range - if your local store has a Tesco NutriCentre attached to it you can by from there.
Hope this helps. As you can see, like Love A'kin I am evangelical about the products
