Lower parallels are the foundation lines that run from the growth points to the tip and support the C-curve. When these lines are demolished (aka over-filed), the nail arch loses its strength and is more prone to breaks, lifting, and side onycholysis. This tutorial is not only about saving of lower parallels. It’s about nail health. Please, share it with your customers 🤞 #nailtutorials #nails #gelnails #nailshaping #nailsofinstagram | Nail Mart USA
