There are a lot of patanjali shampoos available. but the best is milk protein shampoo. it smells awesome plus it removes dandruff and makes your hair shine.
before this I used tresemme shampoo but then my hair fall increased because of this. then I also preferred patanjalis shikakai shampoo but then it made my hair dry. then I started using milk protein which made my hair look shiny. and really it smells awesome. and also its not that expensive. and if you want you can also use patanjali kesh kanti oil its great but it smells really bad.
good luck.
