Reviews

Use on my peeling nails

"I use this on my nails along with the olive and june nail hardener when I give my nails a break from press ons in hopes to nourish and protect peeling and brittle nails"

— Megan (5/5)

Works well!

"I really like using the strengthener combined with the hardener and it works so well!! Whenever I paint my nails the polish chips because my nails break off but now they last for days! Also, I like to grow out my nails and this helps me grow them longer than I would have been able to without the strengthener. The photo is with nail strengthener, hardener, and glossy clear coat on top! Definitely recommend!!"

Helping!

"I teach 2nd grade and art so I’m constantly washing my hands. My nails are thin and tend to peel but add in the handwashing and they’re just a mess. I started using the nail strengthener with just a clear coat, changing it every 3-5 days, and after the first two weeks, I can see a difference. My nails have grown past my fingers slightly which is huge! I’m not seeing the splitting and where I usually can see where the nails are beginning to peel is getting smaller. I’ve tried so many things and honestly this is the first one that works!"

My nails are stronger and has grown without breaking. I didn't realize this until July. Very pleased with all of their products. Thanks 😊"

Q&A

I purchased this nail strengthener at Ulta and I'm wondering if it applies like a serum or a polish? The liquid looks very light but when I apply it it kind of just disappears! Just want to make sure the product is working like it should :)
Yes! Apply it directly to your natural nails like a polish, but the lightweight formula settles into the nail like a serum, so it can look like it disappears after application. That’s completely normal and means the treatment is doing its thing!
Can I use this strengthener with a treatment like EC, or is it better to just use one at a time?
Yes, you can use the Strengthener with EC polish! We recommend using them one at a time rather than layering them together, so you can get the most out of each product.
Can I use nail strengthener under the peel off base coat?
Yes you can!
Can you use the nail strengthener or nail hardner under the gel polish
You can definitely use the nail strengthener , we don’t recommend the nail hardener. Hope this helps! Xo
Can I use the nail strengthener under the gel quick removal polish?
No, this can impact the adhesion of the gel polish to the nail!
