This might seem like a lot of pieces, but it’s better to have extra than to run out while you’re doing your hair.

If you’re applying extensions to short hair, plan for making 6 to 8 rows on each side of your head. Remember to keep them about 1 inch (2. 5 cm) apart.

Most pre-bonded extensions come with a round heat-protective shield, but if your package didn’t, just pick up a generic hair extension shield at your local beauty supply store. The shield protects your surrounding hair from the glue. To keep it in place, you can clip the shield onto the hair that’s closest to your scalp. It will take time to apply the extensions since you have to do 1 small segment at a time. Fortunately, you’ll get faster as you go.

You’ll probably see the adhesive smear or spread a little as it melts—this is totally okay! You’ll be shaping and securing the extension next.

Roll the bond and hair for about 5 seconds to get a solid hold.

Once you attach the extensions to the bottom row, let down the next row of hair and add more. Finish with the rows on the side of your head.

Pop on a cap or braid your hair before you go to bed so your hair doesn’t get tangled while you sleep.
