Goes on like Polish but your nails soak it up in a minute or two! I've been able to grow my nails out again! And they're definitely stronger than they were... After acrylic removal.

Purchased to repair press on nail damage. My nails had white spots and scrapes all over them and now they are pink in color, strong, and healthy looking!! Great product!

Wears extremely well. No toxic smell. Quickly dries. Follow directions for remover. Great colors. I have to order online, so fast deliveries as well.

I was a nail biter for most of my life and even though I’m not anymore, my nails are in pretty bad shape and they’ve always been weak and easy to tear. I’ve used other strengtheners before and they worked, but they were toxic and they didn’t repair the ridges. I’ve been using this every night for just over a month now and not only are my nails really strong, the ridges have improved dramatically. On a few of my nails, they are completely gone. My nails are growing so fast now that I’m having to trim them regularly for the first time ever. This is really good stuff - both effective and non-toxic.

The pictures are from the same nail 4 weeks apart. Even though the lighting is different, my nails are actually a different shade now. I can’t see “through” them anymore.

I've only been using this for a week but my nails are already improving. I had no nails and they were peeling and fragile.

So far i have only used this product between nail polish for a few days at a time so i cannot give a full review but even with only using it a few days at a time for a few months now my nails seem to have less ridges and a bit stronger. It is easy to use when I remember to put it on. :)

I scraped my toenail cuticle 15 years ago on a desk. After that, it stopped growing out and only grew up (raised from the nail bed) so that it became thick, dark, and ugly. After seeing four foot doctors and having my nail cut off 4 times, I was told it would never grow back the same. Well, after using Kapa Nui's Nail Repair and Cuticle Oil on a daily basis for 10 months, new & healthy nail is starting to grow!!!! It's actually growing close to the nail bed and looks pinkish!! I'm so ecstatic. Check out my 2 before pictures vs my 2 after pictures! I will have to give another update in a year when more of the nail has grown! I feel like I was divinely guided to these wonderful products!! Thank you SO much!!!

I LOVE all of the Kapa Nui Products!
I bought some turquoise colors which match my new birkenstocks and am very happy with everything.
I'll order more colors soon!!!
GREAT products! NO smell, easy to use!!!

I used this for three days between polish applications. It definitely hardened my nails. I have gotten it before from Amazon and I would recommend NOT getting it from Amazon. The product I got from the website is thicker and more effective. I’m going to use it between polish applications and then in the winter when my nails are hopeless.

I started using another product from a very popular brand (due to great reviews) until I turned it over and read the ingredients. Most of those ingredients are dangerous and I couldn't understand how it was allowed to be on the market. I decided to try this and Wow! I'm impressed! When it's used, as directed, it really works! I've never had long nails. I wash my hands often, do gardening, crafting, etc. I'm hard on my nails and for the first time, I have salon looking nails and they are natural.

Amazing product. My nails look healthier with each use. I can’t wait to see how they look after a full month.

Love it love it love it. My nails thank you.

Really felt the effect of this one. Most cuticle oils work one night and my skin is dry again next day. I used this for about 4-5 days and can really feel a difference already.

The nail strengthener seems to be working. My nails were thin brittle and had lines . The lines are slowly disappearing and my nails are much healthier
Thanks

My nails were in bad shape from doing home remodeling. After a few uses I can already feel them getting stronger. It also makes them shiny and a bit opaque like a polish. Very happy with this product. Shipping was also very fast.

I've struggled with peeling/cracked nails for over 8 months. It was slowly improving on its own, but I used this for a month most nights, and it seemed to make a difference! Any last bit of nail that was peeling/cracked seemed to strengthen, my nails feel stronger, and seemed to grow a bit faster during use. I was skeptical, but would definitely recommend!

I’ve been using this Repair & Strengthener for over a month, and I’m really happy with the results. My nails feel much stronger and healthier, and I’ve also noticed that they’re growing faster. It’s easy to use and has become part of my regular nail-care routine.

The Nail Repair & Strengthener gives my nail a healthier look. The tips look brighter and whiter. I have many complements on my nails when I use this. It is simple to use.

Peeling nails no more! Best they have been in nearly 20 years. And stronger.

I use this daily and my nails have been growing without breakage for the first time in my life:)

I have been using the Napa Nail conditioner every night since July 4, 2026, which I wash off in the morning. I have been watching my nail growth. It’s like drawing a line on my nails. You can see exactly where I started. New growth
has little to no ridges, nail is white and it just looks healthy. I will use nail conditioner for eight weeks when I expect the whole nail will be grown out. Here I am at the advanced age of 83 and I have always wanted beautiful nails. Better late than never.

Excellent product for nail repair. This helped to strengthen my nails to prevent breaking. After years of gel polish and acrylics my nails have always been thin and prone to breakage. I also had ridges in a couple of nails. This product is the best I have found for strengthening and repairing.

After 1st use my nail feel healthier/stronger!

After using this less than a month my nails are strong. They aren’t breaking or tearing like they have been my whole life. No smell at all. Easy to use and quick drying. I also purchased nail polish, nail prep and remover and haven’t used it yet. Great product!

I love having my nails done but I am raising a bunch of boys - so my manicures never last. I’ve tried different products trying to make it last longer and all of it tore my nails and dried my skin out more.
Well- I cannot be more thrilled with finding and trying Kapa Nui nail products. It is so easy to apply, does not stink, does not take forever- and it LASTS. My first application easily lasted 7 days and looked so much better at the end of those 7 days than any other products I’ve used. The Maui Rose color is BEAUTIFUL and I cannot wait to stock up on more colors.
I will say the remover’s consistency surprised me- it took me a couple of attempts to remove all of the polish- but it is no deterrent to me personally.
The nail repair is easy to apply and wash off the next morning.
Long story short- if you’re on the fence, don’t be.. you won’t be disappointed.
I will definitely be a repeat customer.

This is the only repair formula that has ever worked for me!
