This product works, worth it
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.

Fingernail Help!
I have been struggling with nail breakage for several years and have tried vitamins, supplements, collagen, etc. in attempt to improve my nail health with no success. A few months ago I was getting a mani/pedi and the technician used one of the nail products from Nail Tek on my fingernails when I told her about my nail breakage issue. It really seemed to help so I looked for it online and found the whole line of Nail Tek products. I ordered this nail strengthener and immediately started using it. My nail breakage has definitely improved. While I am being cautiously optimistic still, I really think I found the solution with the product.

Really works!!
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.

Works great!
I rarely do a product review but this nail polish has been amazing. My nails kept breaking and flaking. Nothing helped. My doctor had no advice. I've been wearing this for 2 weeks and my nails are significantly stronger and they stopped breaking and flaking. I highly recommend it!

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

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!

Es increíble, estoy muy contenta con la compra, tras haberlo usado 2 semanas las uñas me han cambiado por completo!. La verdad es q estaba algo exceptica en que me ayudara con mis uñas, alguna vez me hago las uñas semipermanentes, lo hago pocas veces por q tras retirarlas y durante meses se me quedan las uñas muy frágiles y quebradiza... Tras aplicarme este producto tengo las uñas fuertes, no sé rompen y no están finas, todo un acierto.
