I have used many patanjali products from which I am going to review on this patanjali shampoo.As I watched an advertisement on t.v about this shampoo I have purchased it as I am interested in herbal products which are free from chemicals but after trying this I have changed my mind that all herbal products are not good in giving its full benefits.But I have no claim on side effects as it doesnt show any of it but it had not become a solution for my hair problems.
