It depends. I run at a nice dirt trail that has very steep hills.
I weigh about 200 pounds and I'm muscular so running is difficult.
I run about 4 miles every other day or so.
I use the RunKeeper app all the time so my 1 mile is 8 - 10 minutes.
When I run my fingers through my hair I occasionally feel a crusty tiny bump on the temples or vertex (back top) of my scalp.
If I pick it off, it doesn't hurt and it's usually a small crusty red cluster/dot.
What is this? Is it normal?
I don't use conditioner, only Head and Shoulders...
