I think tape up haircut looks really good on men, but I don't like it when men use hair gel to make spikes on the top. I like it when they leave the top alone or when the top of the haircut is cut shorter than usual. Then it looks very neat and stylish.
I also don't think that all hair stylist can do this haircut well. I have seen quite a few boys with a badly done tape up. The fading wasn't done right so there are literally lines when the hair is getting shorter. If it's done well, it shouldn't be overly visible that the hair is getting shorter. It's a good idea to go to a hair stylist that has a lot of experience with this hair style.
