Olive & June Nail Strengthener | Heals & Conditions Weak, Brittle Nails | Up to 77% Increase in Strength | Prevents Peeling & Ridges | Celery Seed + Flora Complex | Vegan, Cruelty-Free Nail Treatment

This Nail Hardener is excellent!! I have week & peeling nails due to damage from Shellac Nail Polish. I can apply this product as a base coat before I apply any other polish to protect & harden my nails. Great product. Thank you.

My nails were a mess after gels. I think I became allergic to all things fake nails. This is helping (along with CND keratin almond oil) to heal my nails. They still have a long ways to go but I used this 3 -4 times a day to start. And now juts morning and night.

Absolutely love it. As you can see in my before picture my nails were absolutely horrible. So damaged and was so painful. That was about a month ago, and since then I’ve been applying this to my nails twice a day and you can see how much my nails have healed and improved! They are still not 100% healed but I’m so happy with my results and know they will get even better.

After I noticed a spelling error on the packaging, I became alarmed that this might be a bootleg / knock off product. None of the other pictures in the reviews that show the back of the bottle have this same misspelling, and the message on the back of the bottle is also formatted differently than the ones in the other reviews. It just makes me think that the version I got was not created by the real Olive & June company. Therefore I do not trust what is inside this bottle. I put one coat on all my fingernails before I noticed the weird issue with the spelling. My fingers sort of sting, and I don't know if that's normal.

My wife is a huge fan of Olive and June polishes, she thinks they're high quality and the brushes are her absolute favorite. When she saw this, she was excited to try this as one of her nails developed a split quite a while ago that hasn't resolved on it's own. She said that this was easy to apply and it's got that same brush as they use in the polishes that my wife loves. She says that this goes on easily and dries to a matte finish (or maybe just absorbed into her nail) very quickly. She was actually surprised how quickly it dried. She has been using it for almost a week and the split nail is still there, but my wife thinks she is seeing other signs her nails are being strengthened.

My nails are so thin and I work with my hands all day. This strengthener absorbs into my nails and makes them much stronger. I will buy again.

BEST PRODUCT I'VE EVER USED! I had severe nail peeling along with very weak nails. I started using this product fully not expecting it to actually work, as all the MANY others I've tried before, however I was EXTREMELY shocked that even after the first use, I could see a difference. I used this daily for a week as I had severally damaged nails, and now, you'd never know I had a problem at all. Would absolutely 100% recommend this product to anyone, and I already have!

Little stinky but it drys quickly.
