I have used this product as directed, twice a week, and it has made a drastic improvement in my nails as far as health and strength. I use it along with the Nailactin so it may be the combination which is making the difference. Well worth the money.

I really like this product. I have used it once/day since I purchased it and my nails are definitely healthier and stronger,
