I’ve been using this regularly and noticed my nails feel stronger and less prone to breaking. It goes on smoothly and dries quickly, so it’s easy to include in a routine. With consistent use, my nails started looking healthier and growing a bit better. It’s a simple product, but it actually makes a difference over time. Great option if you struggle with weak or brittle nails.

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.

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
