Better than the one I had been using, by FAR

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.

Works pretty well!!!!

Going on, spreads easily with the brush Gives acrylics look on nails.. Stays on pretty good for a few days before chipping... It's one of the better naik hardeners for breakage and nails are getting strong... I do recommend giving it a try....

Thin nail must

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.
