It’s awful. When I played hockey I grew mine out one season and it was miserable. It’s significantly hotter, it sucks trying to sleep with it, and it needs a lot more shampoo. It serves no purpose other than the way it looks.
When I played hockey back in the early to mid-70’s we didn’t grow our hair out for hockey because most guys had long hair already.
We were all coat-tailing of the previous 60’s hippie faction. That, and by then all the top rock musicians had the flowing locks.
Shampoo?
