Onsen Secret Nail Reboot Duo!
I’ve been using the Onsen Secret Nail Reboot Duo for a few weeks now, and I’m genuinely impressed. The set feels like a mini spa treatment for my nails — the formula absorbs nicely without feeling greasy, and my nails already look smoother and healthier. The accompanying prep step really makes a difference in how well the treatment works. I’ve noticed less peeling and breakage, and my nails have a subtle natural shine that didn’t happen with other products I’ve tried. Easy to use and gentle, this duo has quickly become a staple in my nail care routine. Great for anyone who wants stronger, more resilient nails without a complicated process.

If you have dry nails, this helps
I really like this duo - I have dry nails and just seem to not ever keep them moisturized enough. I tried this duo after reading an article on how to take care of your nails if you're 50+ and these products were recommended. They've worked really well for me. I initially only used the the nail lotion and had good results. The nail oil elevated my routine. I use this twice a day - in the morning and then in the evening.

Meh.
It works okay. My nails haven't grown that much longer, but my nails look and feel a lot stronger and healthier.

Really works
I have very brittle nails and I was surprised how well this worked to strengthen my nails with just moderate use.

Who gets compliments on their cuticles??
I bought these in a bundle about a year ago, and thought the reboot oil would be the best thing for me to use before bed every night, and I used it for months every night without fail. My cuticles were moisturized and healthy, and I often get compliments on my nails (I've been doing overlay for a little over a year and my natural nails are very long under the gel now), but when flying last July was the first time I had ever gotten a compliment on my CUTICLES. Yeah, that was definitely a first. I was boarding the plane and the flight attendant that was in the aisle caught sight of my nails (I presume as I was holding the strap of my carry on up near my shoulder), and said "Oh I love your nails...Oh and your CUTICLES! Beautiful!!" I was just kind of shocked! I smiled and said thank you and carried on, but who ever gets compliments on their cuticles?? Anyway that was after probably 6 months of using the reboot oil nightly. One night I decided to try the serum - I used to keep it at my desk, but realized I didn't use it there, so I decided to try it in place of the oil for my nightly routine. Fast forward about 6 months, and I'm realizing that the serum is even better than the oil, if that were even possible. I told my daughter the last time I did my nails that I needed to take off some length because they were just getting too long, and I did...but two weeks later they feel like they're even longer than they were the last time I did my nails and had to take the length down! I know what you're thinking, it had been two weeks, of course they grew! But, this is assuming my nails are like everyone else's nails. Mine literally take an EON to grow. Or at least they used to, before this serum. I can't tell you anything about the strength of my natural nails, but I can tell you that they're growing fast under my overlay, and I used to get away with a fill every month...now I have to do one every two weeks. That, and my cuticles are compliment-worthy, apparently. You be the judge.

Nothing Special
Sucker that I am, I bought all three of this brand's products - nail oil, nail serum and hand cream - and I am not impressed that they're anything special, just expensive. The description led me to believe this was a Japanese product, which it is not. Frankly, I say save your money and buy something else.

I have been using this for 3 months now & I can’t stress how brilliant it is. My nails were constantly peeling & this has stopped & my nails look so much healthier. I particularly like the oil

Overall very good! The cuticle cream and nail oil work really well together — my nails look much healthier and feel stronger after just a few uses. Absorbs quickly and smells nice too. Definitely recommend for anyone dealing with dry or damaged nails.
