IBX does not work by nourishing the nail growth at the matrix via the bloodstream. IBX helps to encourage fast natural nail growth because it re-enforces the nail plate layers instantly within the nail plate which stops nails from breaking and chipping and delaminating and wearing.
Eg. My nails grow like crazy and get real length when I wear only Shellac, so in that way you could say confidently, that wearing Shellac will really help your nails to grow. But if I remove and don't replace the Shellac, my natural nails do not last long with any length as the protection is gone.
IBX stays within the nail plate, with or without wearing Shellac, which will be a real bonus for when I remove my Shellac but don't replace it immediately.
From within because, the nail plate is full of tunnels and holes. Those tunnels and holes get reinforced with the IBX repair which is forced down into the plate with mild heat and when it has polymerised under the UV lamp, it both fills and attaches to any loose layers; as it cross links, it not only cross links itself, but also pulls thoes loose layers together and stops moisture from drying out the plate further, hence why any ares of dehydration disappear almost instantly (in some cases instantly) before your eyes. Because there is less chance of moisture soaking into the nail plate and softening the surface, there is also less likely hood of causing further damage (thoes dreaded white spots) to the nail plate.

Why do nail people always have to complicate simple things? I promise you ladies, I have known Linda and Jim for a good half of my life. I have watched Linda's nails improve using IBX for a year or more. If they tell you this product is a game changer and using it will improve the dreadful condition allot of your clients nails are in (how many posts have we had about dehydrated nails with white areas?) you can believe it. Buy it, try it and try not to complicate a very simple but amazing service which will sort out the problems you have all been complaining about. Be an early adopter and don't wait ... I've got mine!
