Late to conversation, but if you think you still facing hair fall and your hair growth rate is very short then you are probably in the same state i was 2-3 years back. Though you could left your hair unshaved and could not use a hair system, but its good move to start using it from now as you wont face any problem of transition phase in future and you can gradually change your hair style and try different systems. But remember if once you shave your hair they either wont grow at all or take much longer time to appear significant. Long back local guys asked me to shave my full hair so that your hair will grow thicker.. thats complete myth i guess as i shaved quite some thime as my hairs were not growing fast and were becoming thinner and thinner, but finally they are now at my head like ruminant hairs... let us know about the state and look after you come back hair cut !
