How many packs of hair do I need for a full install?

We usually recommend 2 packs for a full install under 20" in length. The longer the length the shorter the tracks will be on the hair weaves. This means you have less coverage with 2 packs of hair if you decide to go for a length longer than 20 inches. In this case, we would recommend you purchase a third pack for safe measure. It's always better to have a little extra rather than not enough. There's nothing worse than going to your hairstylist appointment and not having enough hair to finish the install. If you don't use all of your hair, you can always use it to touch up your install or for a future installation down the road
