Tight Knot Method
If you have shorter layers, you'll notice a lot of hair wants to peek out of the bun.
1. Prep the hair with a dry shampoo. This will give it the texture needed to keep strands from sliding out of place.
2. Then go into the ponytail method, but when you twist the hair, make sure you're twisting as you wrap the hair around the base of the ponytail. Alternatively, you can skip the band and wrap your hair around your finger. For this bun, the tighter, the better. It should actually look like a knot.
3. Pin and add more dry shampoo to the hair that was left out for even messier texture.
