It's the first-ever treatment in the world for cuticles and nails that will also provide ongoing defense for fungus and inflammation and wound healing through daily regular use.
Doron Santo - Creator, Explorer, Sage
I have always struggled with dry, cracked nails and cuticles, but the Nail Reboot Oil has been a life-changer for me. The velvet-rich texture of the oil feels great on my nails and cuticles, and it doesn't leave any oily residue. After using it for just a few days, I noticed a significant improvement in the hydration of my nails and cuticles.

Nail Reboot Duo Is Working – Stronger Nails Already!

All right, nails nails nails, ladies and gentlemen! I’ve been using the Onsen Secret Nail & Cuticle Reboot Oil along with the Cuticle Conditioner Serum, and I can already tell my nails are getting stronger. The oil has a light scent—not bad at all—and it feels really nice going on. The conditioner has a creamy texture, almost like a glove for your nails. I’ve been applying the oil every night, and I’m excited to keep seeing results. Definitely recommend adding this to your nail care routine!

Cuticle 2 part serum

Love this product! I have only had these for 4 days and my cuticles are already soft. I have tried a much higher price product without positive results. I have dry tough areas on sides of my nails and this serum has shown a 60% improvement in just a short time. Love the oil applicator is a roller ball that make dispensing do easy and just enough.

Endlich starke Nägel

Ich benutze diese Kombination jetzt seit einigen Wochen und bin begeistert. Meine Nägel waren immer brüchig und trocken. Seit der Anwendung sind sie deutlich gestärkt. Zu Beginn habe ich beide Produkte täglich benutzt. Mittlerweile benutze ich das Öl noch täglich,den Conditioner alle 2-3 Tage. Die Nagelstruktur ist glatter und glänzender geworden. Die Nagelhaut weicher und extrem reduziert. Wichtig ist die regelmäßige Anwendung.Klare Kaufempfehlung.

Hilft schon ein bisschen, aber mehr als eine Art Pflege für die Nägel.

hilft schon ein bisschen. Ich finde es ist mehr eine Art Pflege für die Nägel, es tut ihnen gut, das merkt man schon. Aber es reißt einen jetzt nicht raus.

A great product

Lovely oil and gel, smells great and is a game changer for the condition of my nails. I have damaged nail beds due to arthritis and the oil used regularly really helps the ridges and splits to smooth out and recover. Very good value for money too, you get a good amount in each package. Easy to use. I keep the oil next to my chair and the gel by my bed so there’s no excuse not to use both every day.

Finally a solution to my dry cuticles!

Finally a solution to my problem cuticles! I have tried literally everything and am so happy to have found a winner. I keep both the oil and cream next to the couch and apply frequently in the evenings especially. These two products have completely transformed my nails and the skin around them. The oil will last a long time - I have used consistently for a month now but at least 85% of the product remains. As others have noted it’s not greasy. Fab fab fab!!

sehr gute Nagelhautcreme

ich hatte sehr trockene Nagelhaut und das hat sich nach ein paar mal eincremen super verbessert. Gerne wieder

Unfassbar toll. Ich konnte es kaum fassen.

Ich liebe das Öl. Verwende es schon seid mehr als einem Jahr für meine Fingernägel. Nach massiver Mangelernährung und massiver Antibiotikagabe hatten meine Fi gernägel sehr gelitten. Ich hatte vorher schon ein anderes Öl verwendet, dass keinerlei Veränderung brachte. Dann bestellte ich mir das Onsen Secret Öl. Schon nach der ersten Anwendung sah und fühlte ich den Unterschied. Der Nagel und die Nagelhaut saugten das Öl auf. Die erste Woche verwendete ich das Öl stündlich, nach einer Woche dreimal täglich. Heute 1-2 mal täglich. Dieses Kombiprodukt habe ich mir nun für meine Fußnägel gekauft, die ich nach schwer Fußverletzungen nun auch wieder schön und gepflegt haben möchte. Die Nägel saugen die Produkte nur so auf. Was ich besonders liebe - das Produkt ist so eine Art Trockenöl. Im Gegenteil zu anderen Ölen zieht es schnell ein und hinterlässt keinen ewig langen Ölfilm sondern nach der Pflege kann ich sofort weiter arbeiten ohne überall Fingerabdrücke zu hinterlassen und ich kann auch zügig meine Schuhe und Strümpfe wieder anziehen. Total angenehm. Außerdem ist das Produkt, Öl wie Serum unfassbar ergiebig. Die 30 ml Flasche reichte trotz regelmäßiger Pflege fast ein Jahr.

Does magic

I bought it instead of Opi nails & cuticles oil-to-go that I mostly used when travelling. Onsen much exceeded my expectations, it smoothens cuticles but also nails, making them more hydrated, healthy and elegant even without any polish. I love this product.

So helpful for healthier nails! The oil and moisturizer combo is key. I wasn’t seeing much improvement with the moisturizer only but adding the oil made my nails much healthier.

Better even than Flexitol.

I was a huge fan of Flexitol, which I can’t seem to be able to get anywhere. Took a punt on this and frankly it’s brilliant. I have hypothyroidism. Nails were in a shocking mess. I can’t remember them being as good as this. Smell is lovely too!

I love it, once I use it consistently I can tell the difference, and smells so nice.
