my cousin is a highly professional hair dresser, if you like i will ask him ... but you know it is not good to use the same shampoo always ...also you need to be sure of the ph of your hair,,,, for me i suggest you not to wash your hair with shampoo and keep it without shampoo for some days just water.... or change the shampoo... and if you really need a professional expert dont hesitate to call cousin ((saying that Abdallah Haider gave me your number (he is my cousin Name Wael)his mobile is 3254282....
