1. Hotheads suggest using 3 20-strip packs for a full head to add length and volume.
2. Hotheads packs come in 2 sizes: 20-strip packs and 12-strip packs. Ultimates only come in 12-strip packs because you don't need more than 12 pieces for a head. You will only put an ultimate on the top of the sandwich around the crown of the head, and you can use it as the bottom piece of the sandwich on the very bottom row if the client wears their hair up a lot to help it blend.
Hotheads also offer the 14-16" originals in 12-strip packs. These are great for clients who just want to add some volume.
