Nail biotin ultimate strength
I’ve been using this nail treatment for a while now, and I can honestly say it works really well. My nails feel stronger and don’t break as easily as before. I also noticed they look healthier and smoother overall. It’s easy to apply and dries quickly, which I like because it doesn’t take extra time out of my routine. I’ve tried a few similar products before, but this one has given me better results. I’m really happy with it and would definitely buy it again.

Strong, Healthy Nails with a Nice Natural Shine
I’m more of a keep-my-nails-healthy type of girl rather than painting them, and I really like this biotin nail strengthening treatment. It helps strengthen my nails and, since it’s clear, it gives them a nice natural shine without looking like polish. I haven’t had a single nail break since using it, which has been great. The only downside for me is the smell—not my favorite—but it’s manageable and honestly not a dealbreaker. Overall, I can’t complain. It does what it says and keeps my nails looking healthy and strong.

Great product !
This nail fix I call it. Works great ! Nails are growing for sure. Then once in awhile one nail breaks and have to start all over but the trick is to clean you out hands good before putting the polish on otherwise it won't stay on good. It's better than many others. ! My right hand doesn't do good as much as my other hand. Mostly because I use my right hand more. But worth buying.

Simple; it works.
I read a review that stated a customer had no more peeling broken nails from the first time she used this product. As someone who must have 10 bottles of nail strengthener that all promised the same results, I was skeptical. I stand corrected....I volunteer in a charity thrift store, and my nails always looked like s*%$. Peeling, broken, chipped. I applied two coats the day I rec'd this product, that was a week ago. Have worked two shifts at the thrift store unpacking books, cleaning, doing dishes, etc. AND NO PEELING. NO BREAKS. NO CHIPS.

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.

Don’t second guess it- just buy it.
I really don’t review products often. However, I really had to for this one. I’ve had gel nails for well over 5 years with no breaks. I finally stopped doing them in February. My nails were obviously damaged and kept breaking as soon as they started to grow past my finger tips. I figured I’d give this a try since reviews were promising. I followed the directions and applied every 3 or so days. I did 2 thin coats (dries super fast) and I did a coat of instant dry top coat (Sally Hansen). My nails are much stronger, look healthier, and are growing like crazy! Highly recommend.

Really works!
I have problems with brittle nails breaking and splitting. I tried this product and I am really happy with how strong it makes my nails. They are not breaking and starting to grow in nicely.

No complaints
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

Life changing for nail biters
Life changing stuff! I am a nail biter and this makes my nails grow back before I can even finishing biting it off. Love this stuff and its reasonably priced and actualy not kidding with how fast this works. You only need the smallest amount so lasts forever too!
