Which Shampoo should i use regularly?

Hello, I am 22 years old and still not sure which shampoo should i use because their are soo many of them in the market and i want something which is natural and doesn't harm my hair. I've tried Rivona naturals Apple Cider Vinegar but it made my hair very dry and rough. I've tried earlier patanjali's shampoo and also few years back shampoo's like dove and head and shoulders...but still after all these years of trying shampoo's for some time still disappointed to have not found the one which i should use. Any suggestions will be very helpful as I'm clueless about which shampoo should i buy. ( heard a lot about Khadi Shampoo but not sure yet about it ) P.S - My hair type is a bit rough and I'm having hairfall / dandruff and hair thin issues now Thank you :)
