Title: Excellent alternative to the original Develop 10 Program
Review: I used the original Develop 10 Program and it's fantastic for turning short, weak nails into long, strong nails... BUT the formaldehyde in the original formula began to irritate my finger tips so I switched to the Calcium Gel. It's just as good as the original but with no irritation. This is a great product and I'm glad to see that it's becoming less difficult to find.
