Great product.
Great product helped my nails recover fully after having 4 months of acrylic nails which ruined them. This repaired and helped my nails grow delighted!

It really helped strengthen
Ok... So I messed my nails up with gels, biab and not getting them properly taken off. My nails were so thin and weak... Disaster! So scrolled through amazon and found this. I bought it. I used it as instructed pretty intensely at first, then less so after about 2 months. I'm probably 5 or so months down the line and a lot of the damage has grown out now and my nails are growing and are stronger. I think this really helped me. I could certainly feel after I applied a couple of coats that my nails felt stronger, when they were dare I could literally bend them but with this on it was stronger and gave more protection. I would recommend this to anyone suffering with nail weakness

I think it’s working but it’s taking a while for the results to show

Nail strengthener
Not sure if I have given this enough time to work as my nails haven’t improved yet. However they were in really bad condition so I’ll keep using it until they have grown up the length of the nail bed to see what the new nail is like.

Such amazing results!!!
I’ve been bouncing between nail biting (actually ashamed of that 1st pic) and acrylics for as long as I can remember. I’ve always been super self-conscious about my hands, and no matter what I tried (every nail strengthener under the sun) my nails would just keep bending, breaking, and starting over. But honestly, the difference I’ve seen with this product is crazy. I followed the instructions and applied it consistently twice a week. Now, my nails are solid. (See 2nd pic!) They’re holding up through workouts, weightlifting, and even my physical job. I never write reviews, but I really wanted to rave about this because it actually worked. Finally!!

Don’t waste your money
Did nothing to improve my nails. Flakes off easily or chips taking the tip of your nail with it. Went straight into the bin.

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!
