My formerly decent nails that never broke and I had to file them down weekly because they grew so fast were recently breaking, splitting, cracking, peeling, not growing, etc. I was thinking of getting gel nails when I read about this product. Its amazing. After 3 or four days I can see growth and they haven't been breaking. I'm ordering another bottle - never want to be without it.

**black nail polish pics are for the initial (2/12) review, all french tip pics are for the updated 3/24 review posted below** I've been using nail-aid for exactly one month today, and this review is to explain how I used it and what my results were. I should mention that my fingernails are typically weak, thin, and brittle, and it doesn't help that for the majority of the time over the past 20+ years, I've been wearing artificial nails. I removed the artificial nails a few days prior to the day I received it and clipped my natural nails down to about 1mm in length. So really there was only a sliver of white showing. My nails start growing about 2.5 mm in from my fingertips, some a little more and some a little less. Since I've been using this product, there's been 3-5mm of growth. It's differed depending on the finger... not sure why. My thumbs, and the first finger on the right hand showed less growth. My pictures are both the right and left hand (how they look currently). Last week (week 3 of using nail-aid) I broke two fingernails off. This isn't because of the product. I have definitely noticed my nails are stronger and thicker than they were, and I feel like the two tips that broke off (first and middle fingers of my right hand) were more weak starting off than the others. I think they'll be much stronger when they grow out again. I broke about 2mm of length off the middle fingernail, and about 2.5 mm of growth from the first finger. I've also chipped the tips of both thumb nails and had to file down around 1mm of growth, so all of those nails are shorter in my photos than they were a week ago unfortunately. I wish that I had taken pictures then, so you at least could see the full amount of growth at three weeks. Aside from those fingers that I mentioned, I think you can get a good idea of what you can expect in just 4 weeks. I'm not sure if they are growing at a faster rate than other people's fingernails, but I can tell you that they're getting stronger. One reason I've used fake nails for so long was because my natural nails have been so flimsy that I felt like I needed more sturdy nails that would just hold up to everyday life. Apparently they aren't that strong yet, but I haven't been able to grow my natural nails this long since I was in my early 20's. I went through two pregnancies in my twenties, and removed the fake nails because I assumed they'd grow with help of the prenatal vitamins I was taking every day. They grew a little, then they'd split and tear off in a recurring cycle each time. My nails didn't even get as long as they are now during either of those pregnancies. I really think this product is doing something. If it's not actually making my nails grow, I think it's at least making them stronger so they're not splitting and chipping off as easily, so I've been actually able to see some nail growth. I definitely think that this product supports nail growth by making nails stronger, and for the small price, I think it's a good value and that you can't go wrong giving it a try to see if it works for you. One last thing I should mention is that I only used this product correctly the first week. You're supposed to apply two layers initially, then every 3 days apply another coat. Somehow I got it in my head that I had to remove it every three days and start over (applying two coats). So I've still been putting it on, but it may have worked even better had I been following the directions (that are on the package and even directly on the bottle in case you throw the package away). Oops. So I'm going to start using it correctly and see if that makes any difference at all. I'll update if there's a change. I hope this review has helped you! 3/24**Update** I added 4 new photos to show the nail growth since 2/12. I took pics on 2/25, then again today 3/24. Unfortunately my right thumb keeps having accidents. It grows a decent amount and then I just end up being too rambunctious and I manage to break it off. I broke it completely off two weeks ago...and I mean it was down to the pink part, and part of the top layer on the corner even peeled off. Ugh. I'm confident that using this product will help it grow back. I just have to learn to be more careful with my right hand. Also, the first fingernail on my left hand was growing even faster than the others and II did clip just a little off of that one too make it match the others a little better. I also had to file down the first fingernail on the right hand again because well...I just have issues with that nail. The others you can see are clearly growing pretty well. I don't have pictures of them, but I've been using this on my toenails too, and I'm super impressed with this stuff because for years (with the exception of the big toes on both feet), I only grow little slivers for toenails. I didn't even bother painting them because they were so little. I finally have enough of a toenail to paint and they look so cute!! I'm very happy with this stuff. Sorry about the collage pictures. I wanted to put them side by side so that you could compare, and it somehow cut my thumbs off in some of them. (You weren't missing much with the right thumbs since I'm constantly breaking them off. Lol!)

Im on my 3rd bottle. I really love it and it works well but this last bottle I bought must be bad. Its chipping thr same day I apply the coats. Im ordering a new bottle and hoping its as good as rhe first 2 I bought. I still recommend it. My nails are stronger and not as brittle. Growing like they did when I was in my teens. Only giving 4 stars because of this recent bad bottle

It hasn’t really worked for me. My nails look nice and glossy though.

Nunca dejo reviews, pero este endurecedor de uñas lo amerita. Después de un builder, mis uñas estaban en su peor estado, tan sensibles que no podía ni tocarlas. Me apliqué este esmalte como indica y ahora están duras, crecen bien, no se parten. Recomendado al 100%. I never leave reviews, but this nail hardener deserves it. After a builder, my nails were at their worst—so sensitive I couldn’t even touch them. I used this polish as directed, and now they’re strong, growing well, and don’t break. 100% recommended.”

This is amazing. I thought I was going to lose my fingernail. My dermatologist recommended a very strong antibiotic to treat the fungal infection that could result in liver issues. I read the reviews and decided to try the nail-aid Keratin 3 Day Growth. I’m shocked at how much better my nail looks. The infection was so bad, I literally almost lost my nail. It’s now almost completely healed after a few weeks. I’m shocked!!! I’ve dealt with nail infections for 30 years. This cleared it right up. Thank you!!

Using this product in combination with the Hard as Hoof strengthening cream. FIRST IMPRESSIONS, 4/25/24: 5 stars The first photo is my natural nail with no product. As you can see it is extraordinarily thin. This is from 6 years of acrylics, with little to no break. I first started using acrylics because my natural nails are very brittle and would frequently break and split, getting caught on things and causing pain. Acrylics have been a godsend in that regard, but now my nail is so thin that it cannot even support an acrylic any longer. The acrylic pops off within a day. The nail is so thin that even putting small amounts of pressure on it is painful. *This is the middle finger on my left nail, and I will call it Finger1 throughout the review. Because it is SO thin I started with four layers of the Nail Aid keratin polish, using thin, even coats. My nail is not super strong yet obviously, but it does feel better than it did. It has only been one day though. I also painted the new growth on my other nails, which still have acrylics on them. I am hoping that as my nails grow out, if I keep using these products, I can simply stop using the acrylics, as the new growth should come in stronger and less prone to breaking if these products do as they claim. I am not currently using any nail polish, but this product feels like it would be a pretty good nail polish base. It's also nice and shiny, so you could use it for a top coat as well and I think it would look very nice. Nail Aid claims stronger nails in 3 days of use. That is a pretty tall order, so I will update on 4/28/24 (I applied on the 24th in the evening). I do not expect perfectly healed nails, but I will be happy with nails that I don't have to avoid touching. My nails are pretty much as bad as it gets, so I should be a pretty good test subject to review this product. As far as the strengthening cream goes, it says on the bottle that it can be used over nail polish, so I am taking the company at their word. I did put the cream on my natural nail the night before using the polish. Since then, I am using it over the polish, being sure to massage it into the cuticle and rubbing a bit underneath my fingernail, as instructed on the tub. It smells lovely, and there is a ton in the tub so it should last a good long time (a very little bit seems to go a long way). It takes a bit of time to absorb into your skin and nails but not too bad. First impression gets 5 stars, no issues so far and cautiously optimistic. UPDATE ON 4/27/24 Updating a day early because I have been doing lots of heavy work this weekend and the polish peeled off. HOWEVER! Even as rough as I have been on my hands this weekend I have not felt like I needed to baby my fingers without acrylic on them. So my first parameter of "I want my nails to not hurt to the touch" definitely passes with flying colors, they feel so much less sensitive. The second reason I am doing this update now is that another acrylic popped off the nail next to Finger1 (henceforth referred to as Finger2, left ring finger). Visually they are not much different but, even with the Keratin polish peeled off, Finger1 is significantly stronger than Finger2. Finger2 is in the same papery thin and painful condition that Finger1 started out in a few days ago. The bottle does say to reapply every 3 days and I have been very hard on my hands this weekend, so I don't feel that the peeling is really a product defect, I think it's just to be expected. Perhaps not as good for a nail polish top coat like I originally thought though, it does seem to flake a bit. Next update on 5/1/24, which will be a full week of use. UPDATE 5/6/24 So I did not wind up updating on the first because I have been horrendously sick for the past several days, but there's not a ton to update anyway. I don't notice a huge difference from my last update, so I'm just going to keep using and see how it goes along. I will update again after one month of use, so on or around 5/24/24. UPDATE 5/12/24: Well I wanted it to work, but this stuff is impossible to keep on. It peels off SO badly, within a day or two, even with pretty light use of your hands. It seems to take a layer of nail with it too, so I think it's just kinda making it worse. I have discontinued use. I will give it 2 stars, because it's easy to use, cheap, and if you're willing to repaint your nails every other day then it might work ok, but it's too much work for me.
