Replying to Ski Helmet Balding

So over the course of the season I've noticed that may hairline at the corners has been moving back, and the hair on top has been thinning (more scalp visible thru hairs). Obviously, this is male pattern baldness, but do you think that wearing my helmet w/ my hair pushed back over the course of my 100+ day season has any additional role? I theorize crashing with my hair in that position could rip some hairs out, but I've never noticed significant pain/bleeding... thoughts?
