Nail-Aid - Biotin Ultimate Strength - Concentrated Viamin B7

My nails were thin and had vertigo lines. This biotin polish has helped greatly. I apply 2 light shiny coats (allowing them to dry in between each application) and it protects my nails from water damage and has almost reversed my problem. This polish protects your nails against water damage which is a problem for thin nails. My nails started growing without breaking after a of consistent use. Pro tip: Use non acetone nail polish remover if you have thin nails!!! It is safer and won't damage your nails. I hope this helps someone! It has sure saved my nails and it's definitely worth the money.

Much better than the Sally H product!!! Thicker, dries faster, better all around and nails are stronger than the opposite hand done with the Sally product at the same time (but with twice the coats). The brush is wider and I thought I wouldn't like it, but it proved to be the perfect applicator, saving time and providing great coverage. I had used Sally H for years and years, thinking that my bottle must have frozen or had become old, but NO. Sally is thin and takes over 24 hours to dry. Nail-Aid is my new go-to and I am now a big fan. Thank you, Walmart, for the good price on a great product.

I've always had soft, thin and weak nails that break very easily, actually tear. This formula is outstanding. Nothing against nail salons, but I no longer have to go for active length, hard beautiful nails.

Just tried this for the first time. I have ridges on all my nails and they don't grow. It filled in all the ridges which is a big plus. And by the end of the day, I haven't split a nail either. So far its better than all the other brands I've tried

I have strong nails to begin with but this makes my nails even stronger, as if I have the fake acrylic nails!!!! Secret to having Natural Beautiful Nails is using a nail strengthener!!!! *See pics DIY mani w/ natural nails

It does what it says it will do. You just have to be dilgent and follow the directions. My nails are stronger and not brittle anymore. The price is great also.

This product does not do what is advertised! My finger nails still chip and split after I have used this multiple times. Walmart seems to have fallen off a cliff, NO help on anything!!

I have never bought nor used this product yet however based on the description and vitamins information listed I presumed that it must be similar in use to others I have used in my past many decades.

I purchacged this product after reading some reviews because I have thin nails. They grow quickly, but always chip or break easily. But, what I really disliked about this product is how it peels off very badly (1 - 2 days after applying to my nails). *Would not recommend

After using this on my nails it strengthened the nails, however If you wash your hands hours later the nail aid actually peels off the nails. I feel like I've wasted my money on this product. I wouldn't buy again.
