A Chinese physician has told me that using Shui Niu Jiao comb (水牛角梳子) is better than using Huang Yang Mu comb. Whatever it is, I am comfortable using Huang Yang Mu comb and so I don't see the need to use another type of comb. Incidentally, for those of you who are keen to purchase Huang Yang Mu combs, you might want to check out this website: http://65daigou.com.
