I'm in the middle of my DS9 rewatch and totally forgot about the stark difference between Sisko hair and Sisko bald. I just watched the Homefront/Paradise Lost episodes and the episode where Eddington defects to the Maquis and watching Sisko go all badass and lose his shit was fantastic.
Much as I like Avery Brooks, he never got a handle on the Sisko character until he shaved and went back to being Hawk but with a son. They should have let him do that from the beginning.
