I've spent well over 20 years with long hair. It's a pain in the summer and it's a pain under a riding hat. Always kept it braided to keep it out of the road, but long hair it had to be ;-).
Then I started grappling. I braided it tighter, used more elastics, tried different braids. Same result, it's hot and it looks insanely horrible after a good wrestle and the earguards slip around on it. Worst of all, lots of it gets left on the mat.
Sometimes the braid gets stuck under my back, once I even had to tap out to a backward neck crank! But it's the hunks that get torn out which is the worst. I remember the horrified look of one of the guys at the end of a roll during a no-gi session one night, when he literally handed me a goodly hunk of my hair - "I think this is yours?!". All in all not optimal.
So today I did the deed. Off it came!
As it is a very hot day, I can feel the benefits already :-). But the true benefits will be apparent when I'll go have have my next BJJ class on Monday. But how good is that for true dedication to the sport ??? Eh? Eh? ;-) (And I shall ignore those in my wider family who quietly think I'm nuts.)
Yay! Three more days and we're back on the mat. Beauty!
