In the words of my hairdresser who is also a best pal (so she's not selling me anything) - the mixture of ingredients in cheap shampoo and is like using washing up liquid, it will strip your hair of all natural oils and dry it out completley. Even brands like Treseme!!!! I use TIGI honey and oatmeal for my long hair and it is in great condition as this stuff actually feeds the hair and it also doesn't contain and horrid silicone that weighs hair down and makes coloring harder to take due to 'build up'. those are others to avoid, like fructis, pantene, etc. On the times i have run out of TIGI she has suggested Neutrogena shampoo & Conditioner. Hope this helps.
