Severe Dandruff So Itchy My Head Bleeds

i have a lot dandruff,and it’s so bad that i itch so much and some times it bleeds and have clogs on certain areas of head…and..secondly…sems like right side of my head has less hair than left…and losing hair too.

It sounds like you scratch it a lot. If that is that case, of course it will eventually bleed. Stop scratching it and use a good dandruff shampoo. If you are concerned about less hair on one side than the other, see a good dermatologist. It sounds to me that you are pulling hair from the scratching and if you keep doing that, you will eventually make the thinning you are seeing, permanent hair loss.
