I'm looking for mangas with male character(s) who shaves his head/get a headshave in the manga bald, buzz cut or at least a crewcut.

Regardless of why the male character(s) shaves his head; It's important that the male character had hair and shaved it. It would be great if the shaving process is visible, but if not that's fine too. Preferably yaoi, but any genre is alright.
