This started nourishing my nails right away, and I started feeling the difference in 3 days. You can see obviously longer nails in a week or less.
I use it several times a day. It improves your nails, doesn't really make them grow. The do appear to grow stronger.
Your nails grow at their regular rate. Some peoples' nails grow really fast, some really slowly.
It strengthens the nails from where they grow behind the cuticle. So, you might not notice a difference in your nails strength until they have time to grow from the cuticles up to your finger tips (maybe 2-4 weeks). But, if you are diligent and use the product daily you will be AMAZED!!!
I have it sitting on my nightstand and use it when I get into bed. It only takes a minute and doesn't take alot of product. Plus the light, lemony scent is refreshing, but not overpowering. Make sure you put it on the skin below your cuticle as well as the nail and cuticle.
Obviously, the longer you use it, the stronger and longer your nails will be.
I worked in a factory. My coworkers were amazed at how good my nails looked for not wearing any polish. For an experiment, I took it into work and all of my coworkers (men and women) used it for 2 months. Some of them used to bite their nails and cuticles. Within a couple of days their cuticles had completely healed and within a month we all had strong healthy nails. By two months we all had LONG, strong, healthy nails.
Sometimes I quit using it and my nails break off and my cuticles start to tear. So, that proves that it is the product that keeps my nails looking great when I use it diligently.
