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 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.

It covers nails and protects them from splitting

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.

No muy bueno no hizo el efecto que recomendaron .

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.

Love this!

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!
