Well - first you gots to find some REALLY small gouges. ;-)
Can't offer any real help here, but I couldn't resist the joke. Seriously though, if you make your question a little more specific I think folks might be able to offer some guidance. What is it about carving hair that you are having trouble with? What types of carving - caricature or realistic? That sort of thing.
Hope this helps you get some responses. There are several really good hair & beard carvers in this forum so if you make your question more targeted and maybe post a pic of a project you are needing guidance on, you'll get the help and advice you need.
