I have very brittle soft nails that don’t grow very well. I ordered 2 of the bottles of Nail Aid Biotin Ultimate Strength nail treatment and as this is the second day I have used it I don’t have a real sense of trying it out. It goes on very well and the 2 coats did seem to have made my nails less bendable. The nails have a high gloss which looks great and I have to put a second application of 2 coats on in 1 day after using a polish remover and cleaning the nails. This is the first time I have felt comfortable that this product will work as no other nail strengtheners have done so.

This stuff is THE TRUTH! I don't often leave reviews unless I'm seriously blown away by a product or it's shockingly bad lol. I suffer from iron deficiency anemia and had been rehabilitating my once indestructible nails. With this product they're finally getting back to their former glory. Not only does it keep my nails strong but flexible, I find that it keeps my polish on for 14+ DAYS when used as a base coat. After a polish change, I oil my bare nails consistently for a day or so (I like hard as hoof and bliss kiss nail oil or cnd solar, but any deeply penetrating oil should work). Before my next polish change, I moisturize my hands and nails thoroughly, wash my hands with dawn dishsoap to dehydrate and remove the excess oils from nails. Then, I typically apply 2 coats of this as base polish, let dry, followed by two coats of color and a fast dry top coat. It's been several months without any nail breaks!

Fantastic product, noticeable difference during and after use. Very strong coating when using it and strengthens the nail underneath so you develop naturally stronger nails the more you use it. Easy to use and cant really fault it. One of the best ones of its kind that I've tried for an affordable price
