Xtra 4, Nail Strengthener for Weak and Damaged Nails, 0.5 oz, 2-Pack

I’ve been using this stuff for decades after a nail tech literally forced me to buy it after removing my acrylic nails. I’m not exaggerating when I say my paper thin, weak nails did NOT break and had some length to them even after removing acrylics. This stuff is pure magic. Make sure to follow the instructions- one coat a day for a week, remove and repeat. I’ve been using it again for a couple weeks after DESTROYING my natural nails by using too much glue with press-on’s, and it’s helped tremendously. (See pic taken today) My nails WILL grow but, due to an autoimmune disease they aren’t very strong and will break/peel unless I use this stuff. Highly recommend for damaged/hard to grow nails. 💅 🙌🏻

This is a great value for what you get. Two nail strengtheners that actual work. The coating stays on even with extreme work. I was able to have mine stay on for about a week before it started to peal off or get damaged and I work with a lot of tools. It also helps keep your nails looking clean and nice while it does the work strengthening and growing your nails. This also helps me not bite my nails knowing there is someone on it. Overall great product and I’m seeing a difference in my nails.

I accidentally stumbled upon this wonderful product in one of the stores. I was skeptic at first, my nails are extremely brittle they break, bend and take every opportunity to chip. I always hated it. But I bought the product because I figured I'd give the dream of having long, beautiful and strong nails one more try. Am I glad I did! This product is simply amazing. It's a miracle in a bottle. I don't know what else to call it! I've noticed a difference in my nails the first week! They became stronger, they grew faster, they didn't bend or chip! The instructions say to put a coat, nail polish and another coat and then add a coat every day. I don't do that. I sometimes forget. Sometimes when I have extra time I put two or three coats at once. And it's fine, because it works either way. I cannot be more pleased with a product that has successfully done what nothing else had managed to do for years! I will tell you, I am not being paid for this review! I recommended this to all of my friends, I sing praises to it every chance I get. Get it. Try it out. Ordering it online is much cheaper than the store - I paid 12$ for this little thing, and even at much more expensive rate it was worth every penny. Since I've ordered two more bottles and when they run out will order more. It is a wonderful product. You will see the difference in your nails within a first week. I also do a lot of cooking and washing and my hands are in the water/dealing with cleaning agents a lot. I try to wear gloves as much as I can, but believe me you will be amazed how little that would matter to your nails. They will be long, strong and healthy. So get it. You will not be disappointed.

I recently had my artificial nails that I’ve had for many years removed. My original nails were left looking a horrible mess and I had no idea what to do. I decided to try this product and I was pleasantly surprised with the results. After several coats over 2 days it filled in the ridges and left my nails with a high glossy finish. I would definitely recommend this product to anyone looking for something to help repair badly damaged nails. I wish I had taken pics before applying, however I’m posting pictures after using for 2 days. My reason for the 4 star review is because the odor is quite strong.

I grow my own nails with the help of this NailTek! I've used this product for years and recommend it to anyone who wants to go natural. It works very well and quickly. I use it as a treatment and as a basecoat. I go through phases when my nails are really good, then I use it as my basecoat. When my nails go through a rough phase, I use it everyday as the direction indicate. There are different formulas but I just use the extra and cover all the bases! Excellent product and this is an exceptional deal! At my local beauty store this bottle is nearly $15, here I basically get 2 bottles for that price! A bottle will easily last 6 to 8 months.

No muy bueno no hizo el efecto que recomendaron .

After 30 years of acrylic nails, Covid happened. My nailbeds were so damaged, thin, and weak it was literally painful. I ordered this and used it faithfully for 2-3 months, had to regrow whole nailbeds, but it gave them strength and helped me until my nails could stabilize.

My nails are usually very short and brittle and where I work causes them to break easily. I have been using it on the two nails that are grown out for about a week. I paint them and go. It doesn’t chip off or flake off and so far hasn’t even worn off. They have grown that much in a week so I decided to paint all of my nails so they can catch up. But I thought a comparison between how they used to be and how they are now would be helpful. I will never have to pay for fake nails again as long as I can get this stuff. I LOVE IT!!! My nails are quite long now and thick but still flexible. I have filled them down a few times already. I reach into boxes to put product out and a few times I have hit one nail or other on the box or the shelf or wherever. I can feel it bend a little but I have yet to break one because of it. I am extremely happy with this product. And as stated earlier it stays put. I have yet to need to repaint because of it flashing off as soon as it it’s dry. Somehow it seems to bond to my nails and last until they grow it and I need to start again.

Ottimo prodotto per unghie fragili! La uso sia da solo che come base per lo smalto colorato e le unghie sembrano decisamente più sane!

Loving this product. Notable difference after a week. Long term worth, to be updated at a later date

Es lo mejor, MUY RECOMENDADO Me puse uñas de acrílico y me las terminé arrancando Mis uñas quedaron frágiles y partidas Muy delegaditas como papel, se doblaban y dolían Me puse de todo y nadaaaa.!! Me puse este fortalecedor y en 2 semanas mis uñas eran más fuertes y se les quito esas rayas blancas RECOMENDADISIMO ⭐️⭐️⭐️⭐️⭐️

I hardly write reviews but for this I have to do it. It’s a miracle product, I have used it for just 3 days and my nails are perfect. My nails were severely damaged, thin and peeling due to removing gel, it was so bad, I could feel pain if I touched my nails and would feel heat through my nails if I put them in hot water and would bend if they grew slightly. Now my nails are nearly perfect. No longer bend when making my bed and no pain the touch and in cold water and it’s only been 4 days. I’m in awe.

J'avais des ongles particulièrement abîmés tordus et rongés. Apres 2 semaines de traitement(plus ou moins régulier en plus) mes ongles ont bien meilleure allure, même s'ils sont toujours tordus ils sont clairement moins abîmés et plus durs. Je recommande!
