No, we specifically don’t allow Practice Hands to be used during lessons because doing so would discourage you from putting effort into finding models and the learning experience on a Practice Hand versus a human is vastly different. There are some steps you just can’t do, and it’s also surprising how much the heat of a human hand affects the products we use. If you can’t find a model, you will need to work on your own nails but this is limited to 20% of all classes and is designed as a back up if a model doesn’t show up, not as a default.
