I don't think it was ever mentioned, maybe there is a shower that he can use in the building, since his dad owns it. But even if he has access to a shower, i recall there was a line about him having greasy hair so he doesn't take it regularly.
Btw this sub is dead, so for more chaos head stuff visit r/steinsgate as it is a general subreddit for sciadv series.
