Review (5/5): This is the best.
For over a year, my finger nails have been more brittle than usual and on nail was split vertically from the tip almost to the cuticle. I tried other, more commercially known products that only made things worse. I read about Nutra Nails in a magazine ad that said it was on sale at Whole Foods. I got the last dust ladened package they had, but I saw inncredible improvement. Whole Foods is not carrying it any more and I was glad to see that I could get it through Amazon for a much lower price. I ordered 6 bottles so I wouldn't run out. One bottle lasts about 5 months with 2 applications to all nails twice a day. I am happy to say my nails are growing in strong and flexible. The have not cracked in many months. The one split nail is almost totally healed as new stronger growth replaces the damaged nail. I am happy. I highly recommend this product for anyone with brittle nails.[[ASIN:B0073D3PWW Nutra Nail Naturals Essential Oil Therapy, 0.5 Fluid Ounce]]
