Will this anti-dandruff shampoo get rid of dandruff completely?

Dandruff tends to be a manageable but recurring condition rather than something that disappears for good after one product, so 'completely' is a big ask of any shampoo. Used consistently as directed, an anti-dandruff shampoo like this can control flaking and itching well for most people. If yours keeps coming back stubbornly or your scalp looks inflamed, it's worth having a dermatologist take a look, since there can be other causes underneath.
