My husband and I moved to Germany about 6 months ago, and he's can't find someone that will cut his hair in the style he wants; and the language barrier is making it difficult to communicate. His style is pretty simple and I think I can cut it, but would like some advice before I try it myself. His style is... use a #4 on the sides and back and then blend the top into the sides leaving the top a little longer. Can anyone give me any good advice on where to start first?
