1.) Gather thin to medium hair tightly back. If your hair is slippery, add hair spray or gel to your hair to provide a more sticky surface.
2.) Tightly twist your hair.
3.) Bring the twist upward.
4.) Push pic upward into twisted hair with backside facing up and right side facing down.
5.) After pushing pic firmly into hair begin to push the pic upward, being careful to keep picked hair in comb. Then firmly pushing downward, slant the pic into the twist at an angle pushing the pic into the rest of your hair.
6.) This may take practice, but if done properly, the pic should lock into place with the hair from step 4.
