Love this product, growing my nails out after stopping using acrylics permanently and I’m in love with the results. So strong too!

**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!)

Ok so did it make my nails grow in 3 days? No not even a little bit, but it did harden the nail. I would definitely recommend that everyone use this to help fortify their nails. It’s super helpful when you want them strong. I’m sure it will help My nails grow in the long run, but 3 day growth did not happen for me. I’m studying to become a nail tech and this is definitely a product I will tell all my clients about.

Keratin product are not good for everyone, this product didn’t work for my nails.

I am a man and play classical guitar, so I am very hard on nails that are fairly long. But, after reading other reviews, I think people are trying to treat this as something cosmetic-it really doesn't work that way. If you use it as a treatment, you will have great success. My guitar playing really ripped up natural nails, even those with a nail hardener on them. I stopped that and, instead, went to using Keratin about every ten days, removing the old first. Then I started putting cuticle oil over the Keratin layer every 3-4 days-nothing else. My nails are easily twice as strong with no tears or splits. You need to file them regularly to keep the edges smooth, but nothing else. It's true the stuff is thick, but it has never peeled off. I have to use polish remover to get the stuff off. It does thicken somewhat in the bottle as it ages, but keep the bottle tight and buy a second bottle to keep the first bottle full with a refill. It has solved all my guitar playing nail problems and my nails are as long as most women's.

It's been 2 years I think and I'm seeing a significant improvement in my nail bed!!! I had been doing my nails for ages before hand not realizing my nails were having an allergic reaction to gel polish! I had severe nail bed separation! Today, that separation is almost entirely cured thanks to being being diligent with constant applying reapplying of this polish in addition to properly sanitizing and drying my hands. I do still occasionally get my nails done still, and do see some separation each time but it's definitely gotten better. No issues when using regular polish! No longer embarrassed my by sad nails! Progression photos with dates included!

Nägel werden fester und wachsen viel schneller. Leider aber sehr teuer.

Les ongles poussent mieux et surtout plus résistants. En curatif je le mettais 1 à 2 fois par semaines et j’ai vraiment vu une amélioration que d’autres produits en boutiques n’avaient pas donné.

Me ha ido perfectamente para la uña del pulgar a la que, según mi dermatóloga, le faltaba queratina.

È super non ho mai avuto una crescita così

Excellent product. Actually works. Have recommended to my friends and family as well.
