I used to bite my nails CONSTANTLY. After years and years of damage, I was worried that my nails would never look even decent! One day I saw this product and decided to try it out. Not only is it easy to use, but it's helped my nails amazingly! Not only are they growing fast, but they're healing and actually appear strong! So pleased! Also, because the product itself made my nails look neater, it made it easier for me to convince myself not to bite them! Would definitely recommend to anyone!
I had high hopes that this product would help my weak, thin, peeling nails ( a new condition for my nails- no idea why). Unfortunately I can't honestly say I see any difference at all. It is a nice clear coat. Dries pretty quickly. But my nails are in no better condition than they were a few weeks ago when I started using this product.

I have one damaged nail and trying to get this one to grow out. I have only had it a short time but sees to be working.

this stuff is great for nail strength and I used it alone for a few weeks. when I tried to use it as a base and top coat with polishes (no matter what brand), it caused insane bubbles that somehow got worse as I wore the manicure. I couldnt fix it no matter how long I let it dry, or even by brushing nail polish remover over the top to try to release the bubbles. i recently switched to another brand and the problem totally went away, so I know it was this. I had the same issue with other products from this brand (foundation 2 and strengthener 2)

I've been using this product for several months now, applying it every week or so when changing paint. No longer do my nails chip and break, tear on the sides, get caught in my hair during the shower, or bend easily. I've also been taking biotin for the same length of time, but I'm fairly sure this product is doing most if not all the work when it comes to my nails. Very pleased!

I've used Nail Tex products off and on for a number of years. However, I've been negligent in the last year or so, and am now getting back to the regiment that I know works. I just recently found out that Ulta carries the product.

This product is much cheaper than Nailtiques. I wear my nails natural, and it keeps them from breaking.

I most certainly would buy this product again. I can already tell a difference in my nails.

Many years ago I used NailTek 1 and 2 with OK results. Our ULTA stylist suggested using 4 instead. I am very glad I did. My nails are stronger and less flexible/bendy in less than a week. I put on a thin coat every few days. The product has a strong odor, but the results have been worth it so far!

What a noticeable difference in just a week! I have a problem with a few of my nails splitting. I was at a loss what to do so while browsing at Ulta, I found the Nailtek products, and decided to try it. I applied one coat to my fingernails, and two coats to my toenails and have continued walking, bicycling, and washing dishes, AND it has not peeled or chipped.

Been using this EXTRA product for several years and it is SUPER for my thin nails, helps them grow almost immediately and keeps them growing. I am diligent to use everyday to esp. keep my thin nails little thicker and stronger! They look so nice for a female's hands! mc 6-24-2020

I wanted a good nail strengthener to use with or without polish. Seems to strengthen well. I do a lot of cleaning and my hands are in water a lot and it doesn't seem to last but a few days when worn alone
Gram from Statesville NC
I like this product . Its amazing . I had a treat of having my nails dipped and guess what I am going
back to nail tek. It really helps aging nails.
The Favored One from Florida
I purchased this upon recommendation of the Ulta representative, and overall I am happy with my purchase. My nails had been breaking off badly, I applied 2 coats of the strengthener and noticed immediate results. Within a week I did notice the polish chipping, however my nails are stronger and growing better.
Kels from Virginia
Bought this product because it was supposed to strengthen my nails. I had just taken off gel acrylics and was desperate to keep the length from breaking. after some filing and buffing, I put this product on and my nails instantly looked much better! It does seem to help strengthen the nail but after not even a week one of my nails broke. I was so sad! I don't think this product strengthens the nail as much as you would think.
Vicki from Philadelphia,PA
Its been about a week and a half since I've started using this product and I have got to say; it does help if youre a nail biter! I've been biting my nails since I was a kid and I thought I'd never find a way to stop or prevent me from going back. I have not bitten my nails since using this! Mostly because it does keep your polish on a lot longer, so my nails look so nice that I dont want to ruin them. They are starting to feel stronger and I've definitely noticed growth. However, this product smells even hours later. Even after multiple hand washing, I can still smell it on my hands. But, thats also preventing me from biting my nails so I suppose thats kind of a plus.

I decided to try this after removing my acrylics, that I've had on and off for years and have left my nails in a severe state. I've tried cheaper nail strengtheners and the Nail Rehab from Sally Hansen. Nothing else has worked for me.
I wasn't expecting much from this to be honest but after my 3rd or 4th application of removing and reapplying, I can see a visible difference in the way my nails look! My nails were extremely thin and dark pink from damage and they are thicker and lighter after a few weeks of just applying this daily. Of course my nails are still damaged but I knew it would take a long time for them to fully recover.
The polish dries quickly for me and leaves my nails looking much smoother, shiny and professional for work. It lasts a few days (applying another coat every day) for me before I should reapply but I would imagine if your nails didn't peel like mine it would last longer.
I really recommend to anyone who is bouncing back from acrylics.

I have weak nails that split & peel. This product has solved this problem.
Pita from Downers Grove
The only nail polish that helps my soft splitting nails. Other major brands of nail hardener have made my nails worse.
Lynda from Ithaca, NY
Loved how quickly I noticed a difference my weak, dry nails. Went on smoothly, dried quickly and was super shiny. So far, it has lasted the week, without chipping and cracking.

The product is great to put on.

First I'd like to add that if you don't have enough water and adequate vitamins your nails will weaken and split so don't rely on a nail strengther to fix the above. I started using this because I'm anemic and after going through an infection and unable to take my iron due to the antibiotics my nails started to weaken and break, I was suggested to get gel nails for breakage and wrong idea. I took them off and my nails looked terrible so after so running around at Ulta I purchased this and so far it has worked amazing. My flakey nails look much healthier, less yellow and are getting stronger it's still a work in progress but I am seeing a difference
