Does smoking marijuana cause hair loss?
It has been suggested that there is a connection between marijuana smoking and hair loss. However, since many young men are genetically predetermined to lose their hair, a man who both smokes and has genetic hair loss may produce further connections, real, circumstantial or otherwise.

I used marijuanna heavily for 1-2 months, over this period i felt immense “tingling” sensation over my head (only occurred after some time of smoking). As a result my hair began to fall out constantly, i quit smoking and even months later the tingling sensation was there but more faint. My hair to a more lighter colour, thinned and fell out. It took about two years of not smoking and my hair has completely recovered (although it was a very slow process)
