Yeah I get little pimple/sore spots around my crown, but I never use to get them until I started treatment.
When I was in high school I hardly ever shampoo'd/conditioned my hair and I never have any problems, now that I use Nizoral and other type of hair washes I get these spots.
I don't use Minoxidil on my crown, so it has to be attributed to either Propecia or Nizoral. They piss me off, but nothing to major.
