Need Shampoos Recommendations

recommend me a good shampoo that is effective to counter fungus on the hair follicles and even at the base of the head , also please recommend a shampoo that can make my hairs ( They are thick and moderately curly ) more smooth.

I don't know if there is one shampoo that can provide both solutions , but yeah if there is then you can tell me one shampoo or you can tell different shampoos for different reliefs
