I think it's weird. My AH has been shaving his head even before we started dating.
My husband like long hair - I don't. He says I look more beautiful with long, luxurious hair. He has no idea how difficult it is to maintain. He thinks HIS opinion should be primary.
I never talk to him before cutting it because it only leads to an argument.
We actually got divorced in 1990 and remarried 3 years later (No, smile, not over this issue)... BUT one of the discussion I had to have with him before I agreed to remarry was this:
My hair. My decision.
I wish you the best.
