You’re correct: it’s not actually explained but rather dismissed in a pretty funny way. But it does show the line in the sand that the writers (at the time) were not going to cross.
My head-canon here is that Klingons just have silly-flexible DNA and go through cosmetic gene alterations like some cultures change clothes. They meet humans and go “yeah they’re awful but… having hair could be kinda sexy…” Given their tendency to be bold, fearless, and intensely passionate, I think that tracks.
