Really does improve the strength of nails
Terri—November 19, 2025
I like press on nails, but they literally will destroy your nail beds. When my nail beds are getting weakened, I take a break and use this product with great results. I wouldn’t be without it. Read more

A must have after extensions or gel manicures!
Courtney—March 19, 2025
I purchased this item due to my nails looking and being in super rough shape due to getting gel extensions for about 6 months.. I eventually decided to give my nails a break because the nails kept popping off and or cracking so I got a plain gel manicure.. well now that the gel is starting to come off on its own my nails are breaking very easily and not to mention bending back which ofc causes me a ton of pain.. So far I have used this product once and I immediately noticed a huge change in my nails they felt and looked so much better I know it will take a few days if not weeks or months for them to be strong again but I definitely noticed a very small change in how strong my nails are right after using this product Read more

A must Have!
Tena Ledbetter—July 4, 2025
One of the best if not the best nail strengthener and nail hardener I’ve ever used ! I’ve used so many different brands I have a shoe box full of different brands of nail hardeners and this brand is awesome.. it dries so fast and nail literally feels harder ! They are finally growing again and not splitting.. I just ordered another bottle I definitely don’t want to run out ! It’s a must have for anyone having trouble with dry brittle nails or rough ridges ! Read more

Eh
Charis—January 1, 2026
I used it as instructed for a couple days and it just peels. That's with me pre buffing and alcohol wiping my nails. It's very pricey. Not a great product in my opinion but maybe I got a bad batch. Read more
