Our Lash Growth Serum is designed to grow your natural lashes. Lets be real for a second, lash extensions does grow off your natural lashes but some do actually break off. You cant get entensions without natural lashes right? So to keep full lashes you must use some type of growth to keep your lashes healthy. Our growth serum induces the growing phase & provides nurishments to keep that growth cycle going. When you stop using the growth serum your growth cycle reverts back to its natural phase & your natural lashes become weak.
