Embarrassing

I know this is very embarrassing to admit, but OMG I don't know how to get rid of my dandruff!! I used almost all the shampoo already that will suppose to help to get rid of my dandruff but it's not going away. I can't stand it sometimes when my scalp itch so bad!! And I don't like wearing color dark blouse because I was afraid that when I itch my scalp, dandruff will be all over my blouse, lol. Oh gosh, I don't know what else to do anymore, I stop using hair dryer after I shower because I thought that using it makes my scalp dry and it was causing the dandruff but I still have the damn dandruff!! Can someone help me if how to get rid of this?
