The shampoo used my hairdresser, and, of course, was recommended to me to use it at home too. Because it significantly more expensive is indeed as shampoos from retailers initially I was skeptical. But it was worth a try, because I was not satisfied with the condition of my hair. They were lackluster and without bounce. My hair is curly in nature, once a year I'm also a slight perm So far I was always careful to use shampoos without silicones. Unfortunately with the above result. According to my hairdresser This shampoo contains leachable silicones. This brings me from the feeling not quite happy but my hair looks clearly healthier. Jump and shining curls. At the hairdresser I paid about 16 euros for 300 ml, 750 ml here for just under 30 euros. Still not cheap, but if you value beautiful hair can be an attempt machen- every hair is indeed different! By the way, I use the whole series, including conditioners and waves foam!
