Hi, You take the crimp bead that will be included, and: 1. you put it on the few strands of hair (about 10-15) and 2. pull the bead near the root 3. insert the tip of the feather just inside the bead and 4. Squeeze the crimp bead with a pair of pliers. To take off just squeeze with pliers to re-open the bead, Bead has silicone inside of it so it is safe for hair. As long as hair is not pulled with force hair will be undamaged. Thanks for asking. Meli
I need to add that the blue is a bit "bluer" than in pic. The pic is unsaturated. Slim and delicate (about a fourth of an inch wide at the widest part)
