yes it is correct but can we use "she doesn't likes"

No, This sentence is not correct. The correct sentence is - She doesn't like.

Because.. do, does, did.. have, has.. will, would, shall, should, can, could.. and all other modal verbs are "anomalous finites" ..they always take only plural verbs immediately after them. whether an action verb or helping verb which ends with a "s" sound or suffix is a singular.

No! You can't. It should be:- She doesn't like.

Sry i'm asking about why we can't use she doesn't "likes" instead of like because she is a third person.
