ok i know i have dandruff but i was goin through my hair with my had (have buzz) and flakes with red came out wats up?

Dandruff is due to the excessive shedding of dead skin cells from the scalp. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and in fact quite common. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can also be accompanied by redness and irritation.

Is there any way you can get someone to have a look at it for you?
Do you use a specialised shampoo for dandruff/sensitive scalps?

If you're worried that it is something more than dandruff, then maybe you should see a doctor. They may be able to help you with the dandruff in general though.

Well, if your dandruff is itchy and you often scratch at it, it's possible you've got a small sore in that spot from the scratching. Just try not to scratch at it and it should be fine.

have you tried head and shoulders???

[Nihilus]

Heads and shoulders works wonders on me. Try it if you aren't using it.

I agree with Jess (again! You're brilliant, girlie. :)), if you have dandruff, you've probably been scratching (as dry skin IS itchy after all), possibly even without knowing you were doing so, and you may have scratched the skin a bit raw, causing some minor bleeding.
Try not to scratch too much, go down and get yourself some Head & Shoulders, you'll be right.
