I used it as mnay times a day as i can remember and my nails are growing alot faster and healthier.pictures of my day one and one week later. Long review: At first I didn't believe there could be something to make your nails stronger, healthy and makes it grow fast. As someone who bites their nails this has absolutely changed my perspective. If you bite nails you already know your nails don't grow fast enough nor healthy, but I have been using this for one week and look at the difference. I just keep it on my office desk and use it as many times through out the day as I can. Here is my one week review. And I will be purchasing again. The first picture was how I started. Review: AMAZING!!! Highly recommend for weak, thin and brittle nails. - I discovered Nutra Nail back in 1977. It was a clear formula back then and was amazing. I used to bite my nails, and with the help of Nutra Nail, I was able to stop. They also had a TeaTree version at one point. This current formula is also amazing. My ring finger nail on my left hand has become very thin over the last couple years so it's been hard to grow it out and keep long along with my other nails. I decided to start using Nutra Nail again, and the nail has become thicker and is now growing nicely. ## Features - American Made, Premium Quality - Nutra Nail Products are Proudly Made in the USA - Beautiful Nails in 5-7 Days - Our growth and strengthening treatment helps you achieve visibly stronger nails and noticeable regrowth in as fast as 5 days!
