Edward Plattinum there is a whole list of barbers that specialize in Afro hair in the following group: https://www.facebook.com/groups/emailbssk/ You should post the same question there or just check the files section for barbers. As far as I know the closest you can get a decent cut is Daegu near camp walker, which is 20 minutes from Ulsan on the KTX. The only other barbers I've ever seen in Ulsan who know how to shape afro hair are dudes that may work for HHI and have their own clippers...good luck finding them though! LOL...

Visit Seoul and Itaewon(for the haircut) ha, I lived in Ulsan for 6 years...after moving to Seoul, wondered why I stayed in Ulsan so long(and I don't mean badly about Ulsan, some great places there and wonderful people, just meant stopped growing professionally and got into a rut after about 3 years in Ulsan and when I was in Ulsan there was 2-3 other foreign teachers haha).
