I have to go outside and visited new place in very single weekend. That's why my hair need to clean properly and accurately. So I need to pick exact shampoo that will work for me. As I'm a traveler, my hair gets dirt I'm a fan of using clarifying shampoo. There are different types of clarifying shampoo in the market. So you have to select the best one which works for your hair. I find some information about hair types and which clarifying shampoos are suitable for your hair in simple google search. Then asked my doctor and got some lovely shampoos for my hair type.
