Whenever I do cardio, my scalp and face start getting really itchy. I feel kind of embarrassed at the gym because I constantly have to scratch all of these little itches on my scalp and face, I am afraid people will think I have something wrong with me.
It has been happening for a while. To the best of my knowledge I don't have a new shampoo/gel/lotion of any sort and it happens in all locations that I exercise so I don't think that it is an allergic reaction.
Any ideas what this could be caused by? Or am I just weird?
