Sometimes I have to stretch my scalp.

This is because I have several impacted vertebrae and it makes my skin ache.

Probably causes baldness too, an impacted vertebrae in my spinal column near the top and bottom, one from a footy tackle and the other metal music head banging.. Be gently on your body.

So if you want good head of hair, watch other men who are tall and lean and healthy spine, they probably have nice thick hair...
