During Shloshim does a man’s prohibition for shaving his beard and having a haircut apply to all hair (i.e. ear hair and nose hair)? Thank you.

Shalom, Thank you for your question. The law forbidding a man to cut his hair or shave during the 30 day mourning period is found in the Shulchan Aruch, Yoreh De'ah, 390, 1. There the law states “A mourner is forbidden to cut his hair – both the hair on his head, his beard, or any hair on his body, even in the “covered areas” of his body [i.e. the hair under his arms and the pubic hair], for 30 days” (the law goes on to define the permission to trim the moustache when needed). Based on this we can see that the answer to your question is that the prohibition applies to all hair, including ear and nose hair (except for some trimming of the moustache in certain cases). Blessings.
