Coming up with in-universe explanations is a fun game to play, especially when it comes to things like significant makeup/prosthetics changes that occur over the decades of Trek. With the Klingons in-mind, the concept of generational uniqueness crossed my mind - which is an idea that's FULL OF PLOTHOLES, I KNOW, but just for fun...
What if a species didn't look exactly the same way from 1 generation to the next? There are all sorts of pictures that depict humanity at different stages, but apart from the idea of evolution, what if there were just basic biological distinctions that affected an entire race, creating distinctive looks for each generation? Perhaps only every 3 or 4 generations, rather than every single one. (Worf & Alexander would be happy about that.)
It could be tied to planetary phenomena, but then every Klingon who wasn't born on the homeworld would have different development, so maybe something that's inherent to the DNA.
As makeup/prosthetics continue to improve, it'll be cool to see how our ST species continue to develop under the creative care of backstage talent. For an in-universe solution, I thought I'd throw this idea in the mix just for fun.
