Might work well on it's own
Maybe this works well on its own…however I tried using it before doing the Olive and June gel system. My nails that usually last a week or two, peeled off the same day. Maybe I needed to give it more time, but I probably won’t use it again as a part of my nail routine.

definitely recommend!
after just a few days of using this product i am already seeing results. i am a nail biter so my nails are literally bendy, and working in food service doesn’t help. but i have been using this product almost daily for about a week and my nails are already so much thicker and stronger. will definitely be buying again!

Great nail serum
This is a great nail strengthener! It’s like a serum, and dries/absorbs into your bare nails. It has definitely made a difference in strengthening my nails, along with regularly using hand creams and even massaging my skincare into my nails morning & night. I prefer having my nails bare, so this product is perfect.

Works great
Doesn't look like you're wearing nail polish. Sinks into nails. Definitely notice a difference

Eh
Just ok. Takes a long time to dry when using without polish on top. It is also sticky as it dries. Found that after a week of wearing (solo) my nails still flaked and chipped.

No breakage
This is a life saver! I had a nail that that was breaking and I was so scared that I would have to trim all my nails again. So I applied the nail hardener and my nail was back to normal. Definitely a great purchase!

Magic In A Bottle m!
I work with an industrial sewing machine all day, so my nails take quite a beating. Because of the repetitive motion of my work, I can hit the machine and have chipped and broken my nails. O&J Nail Hardener to the rescue! I put a thin coat BEFORE applying color. After two weeks of trying this product, I accidentally smacked my hand on my sewing machine and my nail DID NOT BREAK or chip! My nails feel stronger yet still have flexibility. If you're prone to peels or chips, this may be the product for you!

Works great!
[This review was collected as part of a promotion.] I used this in between gel manicures when I was worried I would break a nail since the gels made them grow out. No breakage and nails felt good while I let them breathe.

Great Treatment!
The hardener was the perfect treatment between my gel manicures. I have been able to grow my nails much longer since using gel and I was able to swipe this on for a few days in between when I didn’t have time. It was a great treatment to protect my nails and gave shine so that my nails didn’t look bare.

LOVE
[This review was collected as part of a promotion.] Absolutely love this nail hardener. Dries within a couple of minutes and really puts a tough barrier on my nails so I don’t break them. I regularly use press on and such so it’s nice to give my nails a break and not worry about them being thin and brittle.
