I suspected was the shampoo problem . Recently I just changed her shampoo , usually Carmen use Baby Johnson shampoo , current shampoo was give by my mother in law friend , because she bought extra . That 's what my mum and I suspect , so I quickly change back her shampoo to the original shampoo .

Answer: Because Carmen has tried only two shampoo brandsBecause the shampoo is an extra of a setNone of the above choices .It is highly likely that this due to the change in shampoo
