Hey,

Neet rules for female candidates are:

Light clothes with half sleeves not having big buttons, brooch/badge, flower etc. with Salwar/ Trouser, Slippers, sandals with low heels are allowed. Shoes for the female candidate are also not allowed.

Nothing is mentioned for hairstyles but be sure not to be so fancy with hairstyles. I would prefer you to just tie up your hair with a black rubber band.

There is no hairstyle per se that has been advised. But the weather demands you to be cautious. Just do not leave your hair open if it can be tied to a ponytail. That way you do not attract unnecessary checkings. You can braid your hair, tie your hair into a pony. But if its a bob cut, you can leave it open because there is nothing that can be done about it. But if its long hair, make sure you tie it up. In a way, you can comfortably appear for the exam too.
