My hair is very dizzy and has loads of volume, sometimes it really looks ugly, theya re dry too. Can someone suggest me some hair care which will reduce the volume and also give it a lil shine?

You need to first go to the parlour...get a nice haircut,,..and then maintain it from there onwards...shampoo with a conditioner is a must!  Use serum everytime you wash your hair...hair should be washed in a max of every 4 dyas!
