I was just thinking: it's probably a coincidence and the writers didn't think about Chang at all, but this new "tradition" that Klingons shave during war in the 23rd century and have hair in peace actually ties nicely into the only bald Klingon we've seen before Discovery: General Chang.
Chang: Oh now, be honest, Captain. Warrior to warrior... You do prefer it this way, don't you? As it was meant to be. ...No peace in our time. 'Once more unto the breach, dear friends.'
In Star Trek 6, Chang is trying to create a scenario of constant warfare. Since this is his state of mind, it makes sense he'd always shave his head. I wonder why Gorkon never caught onto this.
In any case, I disagree with Mary Chieffo's assertion that the Klingon allowance of hair during war happened after Praxis. The Klingons were very much ready for war in Errand of Mercy and none of them were bald. Also, fans of games like Klingon Academy note the Klingons weren't bald there either.
I say it's better that Discovery explains why Klingons stopped this shaved head tradition (maybe they realized T'Kuvma was a fool as Cornwell put it) rather than put it off till after ST6.
