Let me tell you that this is the best invention ever. I wish I had known about this sooner because it makes it easier for me to whip up a bun. With this hair donut, all I need to do is pull my hair into a high ponytail, tease my hair a bit, place the hair donut at the ends holding it high up in the air, try to wrap the hair around the donut and proceed to roll and twist the donut down while ensuring that my hair wraps nicely around the donut. It's just that easy but if the way I described it is too confusing, check out this video (watch around the 3:55 mark). Just look how perfect and voluminous it looks and I did it all by myself!
