you can "bun with short hair. I would just find creative ways to tuck in my ends. That may be as simple as an under or over flip. I have seen you tube video in which ladies with shorter hair would make a ponytail and loop/tuck the ends then wrap an extension around for more hair in their bun. I never used extension but I thought about it. The important thing is that you practice and new styles will come. Don't be afraid to try a bun or accessory. You may surprise yourself.
and what would u suggest to use as a gel cause i would never use the real gel. what is strong enough to hold down short 4b hair???????
