Good Quality and Works Well
This nail-polish is nice to protect nails from chipping or breaking, and it also dries fairly fast. It lasts for about a week to a week and a half, then you may want to apply another coat, however it is a good quality for the price.

Really works.
My nails have been dry, brittle, and splitting. I have been using this nail product for a couple of weeks now and my nails feel stronger and looks so much better. Use every three days. Excellent product.

Stronger nails, flaky polish
I have been using this for about a week and a half. I do think my nails are getting stronger, but I do find it to be flaky within a day or two after application. Technically the instructions say to remove and reapply every few days, but if you’re not able to do that then it gets flaky.

MUST BUY! This nail strengthener is THE TRUTH!
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!

Has Some Big Issues
Update: I'm now a little more than halfway through the bottle and it has gotten so thick that it's impossible to brush it on smoothly, no matter what I do. It's just... Gloopy. Plus, I've been really struggling to pick up enough of it on the brush because the brush only reaches halfway down the bottle even with the lid completely screwed on. I remember seeing another reviewer mention this but I thought to myself at the time that I would never get that far into the bottle, but here I am a few months later, probably because it goes on so dang thick! Unsurprisingly, this gloopiness certainly does not help with the extra slow drying time. I now have an alternate option on the way and it can't get here soon enough! Original review: every time I apply this stuff it takes forever to dry and still remains tacky for an hour or more afterwards. I've made sure to keep the coats as thin as possible but that doesn't seem to matter. It's especially difficult to apply 2 coats as instructed when starting with bare nails because I have to wait so long in between them. However, some people say that this polish dries really quickly for them, so I'm wondering if not all of the batches of polish are the same. Beyond that, I do like how glossy this polish is and how wide the brush is. Since I use this by itself it does take a couple of coats before you can really tell that there's polish on my nails though.

Flakes 3 days in so don't be alarmed. GREAT for fixing dip/gel damage.
This stuff is amazing! My nails were getting very thin from my stylist filing down my nails too much to get the dip and gel off. I just bought this on Prime Day (just over a week ago) and I can already notice a difference. My nails that were thin, are definitely stronger. My nails are growing out faster and where they are growing in, they are thicker than before as well. If you decide to give your nails a break from gel/dip, definitely look into getting this for that break. If you just use this, it will flake off around 3 days in but that's because your nail essentially sucked out all of the good stuff on the bad parts of your nail. I was amazed to see the difference it made.

No cumple con lo que dice, 2 semanas usándolo y las uñas están igual ,ni endurece ni crecen más fuerte Para mi todo un engaño

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.
