Hairnets aren't just for your Granny! They are great invisible shields to keep your bun in place. I use a hairnet every time I bun my hair, but I hadn't heard about many other people using them like this. Hairnets can be had at any beauty supply store or drugstore. I prefer the ones by Scuncii which you can get at walgreens or the nets that come in envelopes at Sally's. The ones at the BSS only came in black and were thicker than I prefer.
