Chuckisduck,
The bad news would be not educating oneself and not trying to do anything about it after self-education.
On another note and without digressing too much from the purpose of this thread, is there any correlation (genetic...of course) between the prevalence of dandruff on the scalp and MPB? I myself had a lot of dandruff when I was younger and was wondering if this could be a link or indication of future MPB from this?
If a patient had psoriasis, this should be indicated to the surgeon, who may take special precautions.(I'm not a doctor so I'm not sure...about the precautions.)
