Hair sticks are fun, and actually pretty easy to use. The best way to insert a hair stick is to push it gently into your hair and sort of weave it up and down as you draw it through your style (bun, braid, ponytail, etc.) so as to anchor it. Don't be afraid to push the stick all the way down to your scalp; it makes the hold even more secure.
Hopefully I haven't missed any steps, and everything is clear enough to follow. The pictures were all taken in my kitchen by my friend, and they all feature my hair. But don't get too excited--it has since been cut.
Step 1: My Favorite Bun (Cinnamon Bun Variation)
On to the bun!
1. Gather hair together at crown; twist entire length.
2. Coil entire length of hair, putting each successive layer beneath the previous one, so that you end with a column of hair (the height of which varies depending on the length of your hair).
3. Take top coil of column and pull out, pulling it down so that it surrounds the column, flattening the entire bun. Tuck ends. Insert one or two hair sticks to secure bun.
