Very happy with this toning shampoo. I use my regular shampoo 1st and then apply Fanola and leave on for a few minutes then rinse well before applying my conditioner. I feel that it drys my hair out slightly so when I use it, I use a stronger conditioner. Using the product once a week keeps all my brassiness away. Re all the reviews on the USA page: It does not stain your scalp, hands or grout, just rinse well. The smell is not too bad at all.
