Nailtiques Nail Protein Formula 2 Plus, 0.25 oz (Pack of 3)

Update May 31 2025: This is still the best nail strengthener I've ever found. It doesn't just coat the nails with a strong layer of polish, it actually improves the nails themselves. My weak, brittle, dry nails are SO much stronger after using this for the past several months, even without the polish on. They're thicker, too, which is amazing. I am so impressed!! I gotta say, though, I recently tried Nailtiques Formula 2 - the one without the "Plus" - and wasn't as happy with the results as I am with the Plus version. I just wish I could get this in the .5 oz size as well.Previous review: I have had extremely dry skin my entire life, and dry nails and cuticles along with it. The impact of this on my nails has been no surprise: dry, brittle, peeling nails that split and break if you so much at look at them funny.After years of trying many other (much cheaper) options to strengthen my brittle, peeling nails, I finally gave in and ordered my first bottle of this about 4 months ago. I followed the instructions and started with 2 coats, adding 1-2 more coats every other day or two (or three).I noticed a huge difference right away and have continued to be very, very impressed with how much stronger my nails are. I've had very little problem with breaking or tearing despite the fact that winter in Maine usually leaves my nails, and hands in general, in complete tatters. I'm also terrible about remembering to moisturize my hands and never think to moisturize my cuticles, and yet I've had *maybe* 1 nail tear since I started using this stuff. Literally nothing else that I've tried has helped me nearly this much.There are a few drawbacks, however. For one, once the bottle has been opened, the polish in the bottle starts to thicken really, really quickly, until it's difficult to apply a thin enough layer that it will dry within a reasonable amount of time. I've been playing with a nail polish thinner that seems to help, but I feel like it also reduces the amount of time before the polish starts to chip off of the tips of my nails. Maybe the thickening problem is worse because of the smaller (0.25 oz) bottle size, but it makes me hesitant to buy the full size, especially with how expensive this stuff is. (Plus, I can't find this formula in the 0.5 oz size anyway.)The second thing is that the brush is too small - narrow - and requires multiple passes to completely cover the nail. This sometimes results in visible raised lines in between "stripes" of polish. Hopefully the brushes in the full sized bottles are better in this regard.The brush is also too short, making it difficult to access the last ⅓ of polish in the bottle. When I reach that point I always end up having to play around with tipping and inverting the bottle in order to pick up enough polish for each nail (with the lid securely screwed on of course).Despite all of that, I'm still very impressed with how much longer and stronger my nails have been with this polish. I've gone through two and a half of the 0.25 oz bottles since I started using it and plan to buy more when this one runs out.

This protein polish thus far is magnificent. I’ve only been using it for a week and don’t want to get my hopes up but I think this is what I’ve been looking for. I have the worst nails that break, splinter, split, crack and can’t keep any polish on for over two days. I have not used polish with this but this stuff stays on even with me hand washing dishes several times a day with no gloves. My nail beds look strong, pink and healthy. My nails feel naturally hard. 2 of my nails did break but my nails were previously done with dip powder so I believe they were already damaged. I cut all my nails short to start over so I will be giving another review down the road because if this stuff work for me it will work for all!

My nails were completely shattered/damaged from hurriedly removing a full acrylic set at home -- without soaking the acrylic off. I ripped several layers of my natural nail off.With consistent use, my nails were completly repaired, growing, hardened, thicker, and thriving in >6 weeks. A little goes a long way. The only con is you need to reapply after 3-4 days. 10 out of 10, highly recommend, will buy again 👌

I think I have tried every nail strengthener known to mankind and none of them has worked until Nailtiques Formula 2 Plus! My nails kept splitting and peeling and nothing I used made any difference. When I do my nails I put 2 to 3 coats of this on them. I have been using Nailtiques for about a month and the splitting has stopped and the peeling is almost gone. My nails feel stronger and they even look healthier. I hope they keep making this Polish forever. I highly recommend it!

The best thing since sliced bread. My fingernails have been shredded and weakened from years of fake nails. Nailtiques has made my nails grow strong, no more flaking or peeling. I still go for manicures, but my bottle of Nailtiques goes with me. It's the only thing I now use on my nails. Excellent product.

I didn’t realize the bottle was so small. I love this brand, but I’m going to go back to Step 2 instead of this one. It only requires one coat, whereas I find myself using at least 3 for one full polish of the nail.

I haven't had this product long enough to get the results I bought it for, but my nails aren't as yellow as they were.

I cannot recommend this enough. This product has saved my nails multiple times over the years. This is the best nail strengthener on the market.
