in the Navy locks have always been unauthorized....about twists i fought that with an email to tne MC that put that is not the same as an official message i also gve him a brief how twists has been out as long as braids so i didn't understand how u can deem them as faddish-fad means a style that is short in duration....afterward i got an email back saying he understood and take all the emails and send up the chain which i did...and never had a problem while i was stationed there....i am in Va now and i usually pin my twists back
