I have received my order of 3 ' shampoo with a purpose colour treated' bars and am impressed with how gentle it is on my hair.The bars may at first appear a little expensive, but i have found them in fact to be very economical, as the hair is washed well with little use of the bar, and i can see each bar will be long lasting, as claimed.And to have a shampoo and conditioner combined is great, convenient and reduces the number of bathroom items.I feel i have made a prudent purchase here, and pleased i am assisting in reducing the use of plastic containers.From a health point of view, using these gentle products is a big plus, as ' harsh ' chemicals in other products easily diffuse through the scalp into the bloodstream, due to the skin tissue on the scalp being thin.
