I have a badly damaged nail. Will more fequent applications speed up the results?

When I apply it, I put a thick coat on my nails and cuticles and let it sit for as long as possible without touching it (15-30 min or even up to an hour). I use it once a day and it has worked a miracle on my weak, peeling nails! Full results took a month or two but omg I have long nails for the first time ever!

It's $16.99 for a single bottle that contains a brush. The box of the 40 half ounce bottles is meant to be used at a salon as a sample gift for customers. That's why it is so much more expensive.

The box contains 40 small bottles and is generally used in salons to give to customers after they purchase it as a treatment or as a sample or gift. They also sell a bigger size single bottle with a brush for daily at home use.
