Head and shoulders dandruff free is a good shampoo but it effects your hairs you dandruff will finish.
But you will have a huge hair full too. You can use it but only once in a week regular use will result in a huge hair fall so avoid the regular use of head and shoulders anti dandruff shampoo. This is my experience and thinking which I have shared. It is good only for anti-dandruff not for regular use.
