Start by adding a small amount of liquid super glue to one end of the comb. Place a metal spike on top of the glue and hold it in place for at least 30 seconds. Let it dry completely before letting go.
Glue another spike to the other end of the comb. Then, using a ruler, place the rest of the spikes along the length of the comb to make sure there is enough spacing between each spike.
Continue glueing each spike, alternating from one side to another.
Stick the spiked comb in a bed of teased and tousled hair!
