Showering and Hair Loss

1. I read on the Internet somewhere that after you exercise, you should ALWAYS shower afterwards, to keep your scalp from getting clogged with dirt, sweat, and thus aiding against any further hair loss. Any truth to this?
2. What are your thoughts on shower heads that are set on a “massage” setting? Is the deep vibratory water pressure harmful to your hair follicles?

Thanks for your time.

1. Nope, no truth to that.
2. It feels good on your scalp, and you can continue to do it as it will not hurt your hair or cause hair loss.
