I have a dandruf problem and now everytime i scratch it..it bleeds..tell me qhat shld i do to get rid of the d and stop this?

Might not be Dandruf: There are several causes of flaking scalp conditions, of which dandruff (seborrheic deramatitis) is one of them. For one, psoriasis of the scalp can look a lot like dandruff, but will bleed when scratched. If you are having bleeding associated with the flaking scalp, it may not be just dandruff. I would see a dermatologist to find out exactly what is going on. Good luck to you.
