Great nail protection

"I used this when my nails were peeling and brittle to protect them while and work and I definitely felt a difference and was happy with the protection provided."

Super glossy & works great!!

"I love using this nail hardener. It works really well, and is super glossy! My nails break much less with this, and allow me to grow them out longer. The picture is with nail strengthener, hardener, and glossy clear coat on top!"

LOVE!

"I love the nail strengthener because it doesn’t take too much time to soak in, and it’s nice that it only says one layer, which is different than most nail strengtheners."

— Emaline M. (5/5)

Great product

"I really feel like that has helped with nail breakage. As someone who does regular polish about once a week this has helped tremendously. Love it."

— Jess G. (5/5)

Best nail strengthening product!

"I don’t like to have bare nails because that’s when a nail break happens for me. So if I’m not quite ready to do my next mani but need to remove the previous one I will apply this after advanced nail strengthener and I’ve had great results!! 🙌 I’ve had no issues with the polish chipping or peeling when layered over this! It has helped my nails grow long & strong! 😍 Will be stocking up!!"

— Hayley (5/5)

"Beat hardner ever! I have tried MANY, MANY hardners over the years and none ever worked, this one, this one rocks, for the first time ever in my life, my nails are getting stronger and not splitting or breaking!"

— Dotty (5/5)

Nail Hardener is a necessity!

"I really like this nail hardener. I put it on before I polish my nails and after I take polish off. It has made a big difference in my nail strength and also protects my nails from peeling. This is an important part of my mani routine."

— Carolyn H. (5/5)

Perfect! A Neil gardener with

"Perfect! A Neil gardener with a shiny coat so you can wear it alone if you don’t have time to put polish on too!"

Q&A

Can I use the nail hardener after a manicure, even though I used it prior to applying polish?
Great question! We recommend using the Nail Hardener directly on your natural nails before applying polish rather than after your manicure. This allows the treatment to work directly on the nail.
I applied the nail strengthener followed by the nail hardener. When reapplying the nail strengthener, can this be done on top of the nail hardener?
No you would need to remove and reapply :)
How often should I apply the nail hardener? Also, should I remove it with nail polish remover before applying it again?
Great questions! 💅✨ We recommend applying the Nail Hardener every few days for best results. When you’re ready to reapply, go ahead and remove the old layer with nail polish remover first — that way, you’re starting with a fresh, clean base each time. 💖
Can I apply the nail hardener on top of the advanced nail strengthener?
Yes, as advance nail strengthener soaks into the nail you can follow up with nail hardener on top.
Is it ok to wear this directly on the nail under Olive & June Gel Polish Base Coat (followed by the rest of the Gel Polish System)?
Great question! 💅✨ We don’t recommend applying anything directly under the Olive & June Gel Base Coat — the system is designed to work best when the base coat is applied directly to clean, prepped nails. This ensures your gel mani adheres properly and lasts as long as possible. 💖
