My hair is thin and there is few hair remain in left/right infront of head which cover my bare part i.e infront of the head...though there is thin small hair still under that covered part.Otherwise there is dense hair except the front part .I am using Head and shoulder shampoo from past 4 years.Oil I am changing and sometime it is parachute or clinic all clear or other.I like long hair becz my face is big. So,if I am wrong in taking shampoo and oil then plz suggest me the best one that I should use.
