Ways to help my brother?

So my brother has a slight fear of getting his hair cut short, he has told me he wants it done but is scared he'll hate it, He is scared it'll be to cold and he doesn't really like the noise of the clippers.

He explained to me that he wants to get it clippered down to 1" of hair all over in a buzzcut.

How do I help him get over his fear so he can just get it done? I wanna be a good sister and help him.
