I’ve always trusted OPI products and after a particularly stressful 2025, my nails took a beating, so I decided to strip back and try Repair Mode. I’m an anxious picker and having this stuff on hurts a little, just for a second if you’ve got an open cut or split cuticle. However, the difference in my nails since the end of December is mind blowing! They were sore, paper thin, and through anxiety, my onycholysis was awful. Nails lifting from the base if you’re unsure what that is. They were a mess and I was heartbroken as I’ve always loved having nice nails. From the first use, I felt like I was doing something right and the difference is incredible. My nails are hardened, looking healthy, the onycholysis has gone and I can see where the new growth has come though. I’m about halfway to being fully new but the nails that I have are thick and strong. I swim and getting out of the pool they’re not soft or breaking. I’m sensitive to so many things and I considered ordering another bottle as I’m running out but decided to read the reviews. I was shocked to see so many people reporting issues with nails lifting from the nail bed and other horrific problems. Genuinely, if anyone was going to suffer this, it would have been me, and I didn’t at all. This stuff has been a life saver for me!

Bought by my wife and find that it's a good item if you ever had your nails done in a shop and then you get the polish taken off then you find that they are breaking use this product and that helps your nails to strengthen

Strengthens Nails and Repairs Damage
This nail repair polish has been brilliant for damaged nails; it makes them feel stronger and healthier after a few uses. The formula is easy to apply and dries quickly. It’s vegan and professional quality, which is a bonus. The only minor point is that multiple coats are needed for best results, but it’s worth the time. Highly recommended for anyone with weak or brittle nails.

Absolutely works… trust it!
This product is amazing. I have congenital conditions which have always impacted my ability to grow my nails. My natural nails grow heavily ridged, and are so thin it’s absolutely ridiculous. Even with consultant advice, a hair & nail balanced diet along with daily life long supplements including Biotin, Hyaluronic acid, Collagen, extra protein, etc., and applying the likes of Sally Hansen Hard As Nails and 101 other nail growth and strengthening products over 57 years of trying to grow myself a set of natural nails that I only wanted long enough to cover my finger tip and nail bed, I never managed it. My nails have continued to always grow ridged and of very poor quality, splitting or flaking as soon as any white growth was visible above a nail bed. Okay, I did work with horses for a lot of my life so that was hard on my poor nails but even so, everyone else I worked under the same daily conditions as I, but were blessed to not have my congenital issues, managed to keep their natural finger nails short but normal and healthy looking; miles away from my torn specimens, often tender because of exposed quicks after my weak nails would tear midway down its nail bed (ouchie), and my never ending fight with repeated infected hang-nails always adding to my agony. I stared having acrylics after quitting the horses but with my natural weak nail underneath these, regular infills would become an issue after maybe the 2nd time needed after a new set had been applied. The filing needed to create the grip for the infill acrylic to adhere too was so painful as I has such thin nails they couldn’t tolerate even mild filing without the nail bed beneath hurting, and the UV needed to set the gel polish finish would become intolerably painful to bear. So I have ended up becoming used to having nice acrylic nails for about 5 - 6 months of the year if I’m lucky, and then 6 months dealing with the damage caused once having them removed and trying to repair my natural nails to be ready for the next application of acrylics. This time I bought this product as my nails were worse than I’d seen them in my life. All but the thumb nail on my right hand had nails with at least half of the nail bed exposed and extremely damaged natural nail down to the cuticle. My left hand was a bit better but not much. It was then that I splurged and bought this. I applied it twice a day until the first bottle was empty and then bought another and apply that once a day or at least a couple of times a week as I’m still growing out some of the damaged nail from previous acrylics. But OMG I currently have 10 natural finger nails each with 3 - 4mm of nail tip ( I keep them filed to this length as the damaged nail is still growing out so the tips aren’t 100% normal undamaged nail yet), but the fact that even applied over very damaged nails, this product has created enough strength with those to let me have a full set of natural nails. I can only assume that once all of my previously damaged nail has grown out and been filed off eventually, and I’m applying this product intermittently to maintain the continued support to new growth of my undamaged natural nails, I’ll be able to grow them out a bit longer and not need have acrylics anymore. So do I recommend this, 100%. I started using this daily around start of June and it’s now 19th Oct so it’s not been a quick fix but ordinarily no one would ever start with nails as appalling as mine were. It took almost 2 months to get the quicks on my right hand covered because of the poor quality of what little nail I started with. But I’ve now got nails and ones that I can press on the tip growth and not have go concave from being so weak and thin, but which now hold firm on their own and have stopped chipping, ripping, flaking or tearing off during daily activities. This is a first for me! I 100% recommend this. I also have started using Hard as Hoof (purchased on Amazon) and rub this into and all around my nails twice a day as I’m not applying this Opi product daily any more but want to keep my nails, cuticles and nails edges hydrated and healthy. I’m still prone to hang nails as my nails are still fairly short and find this product helps with those. Once my nails can be grown longer I know the issue with hang nails will disappear. Watch for price fluctuations on Amazon and look out for offer periods. I’ll not pay £29 for this no matter how good it is, when I’ve previously been getting it well below £20 the past two times I’ve bought it here. But if you’ve the money, don’t hesitate to give one bottle a try. For most people, I imagine one bottle would invariably be enough to sort their nail issues with extra to spare. 100% can’t recommend this Opi product enough.

Damaged Nails
This product initially worked for me and improved my weak, tatty nails. THIS IS A WARNING....Do not overuse this product it will damage your nails. I didn't read the instructions properly and used it twice a day for weeks. I noticed my pink nail bed was disappearing and the white part was going down my nails. Several of my nails are quite sore. I don't know if I have damaged the nail bed permanently, possibly I have. Its a good product, but it does contain strong chemicals, so use it sparingly.

This actually works
This stuff really works - my nails used to split really easily, after using it for a few months I've just had to cut my nails because I literally couldn't type at work! Be careful as a few people are allergic and experience lifting of the nail, but if you're not allergic then this actually does what it promises.

Le unghie mi si sono sempre spezzate sulla parte “rosa” un dolore cane e mai avute più lunghe di un millimetro . Il prodotto funziona! Le sostiene, le ripara. E quando l’unghia si spezza ( perché ovviamente non fa miracoli e quindi le mie unghie si spezzano comunque) si spezzano solo sulla parte “eccedente” la rottura si blocca e non va oltre. Non ci avrei mai creduto ma una bella svolta.

Compré este producto la semana pasada porque después de la última retirada de semipermanente que me hice noté que mis uñas naturales estaban súper frágiles y dañadas, hasta el punto de que me dolía horriblemente a la hora de hacer cualquier cosa con ellas. Me hago yo misma la manicura en casa y hace poco probé a usar unas uñas postizas, ha sido lo peor que he podido hacer en este mundo... después de quitarme las postizas, el pegamento me dejó las uñas horribles y me dolían mucho, así que probé a usar builder gel para protegerlas y ya no me dolían. Cuando pensé que me habían crecido lo retiré completamente y seguían mis pobres uñas naturales fatal. He probado bastantes productos que dicen endurecer o mejorar la uñas natural pero ninguno igual a este. Con la primera capa que me puse pude notar la diferencia... mis uñas pasaron de estar súper débiles y que dolían solo con verlas a poder tocarlas y sentirlas más fuertes. Solo con el primer uso me sorprendió porque ahora podía limar mis uñas naturales sin llorar del dolor. Ahora llevo ya usándolo durante los 6 días que promete que hace efecto, siguiendo las instrucciones de ponerlo 2 veces al día y sin duda mis uñas están maravillosas y más fuertes que nunca. Súper bueno el producto, es el mejor en el mercado ahora mismo y por lo que tengo entendido OPI tiene la patente, así que es el único en el sector con esta forma reparadora. Por lo que he podido leer, el producto actua en tu uñas creando más uniones entre las células con keratina y vitaminas. De esta manera se incrusta en tu uña, no es solo una capa protectora que se pone encima y hace de escudo, este producto penetra en tu uña y la hace más fuerte en su composición natural. Increíble!! Además, es súper fácil de usar y de poner, es un pincel súper fino que ayuda a llegar a todos los rincones y se seca rápidamente, en menos de un minuto ya está seco y puedes seguir con tu vida normal. No es nada pegajoso ni nada, es perfecto y da un resultado maravilloso!! Por lo que tengo entendido puedes ponértelo como primer antes de la base para la manicura semi y seguirá teniendo efecto. También he visto que puedes aplicarlo en tu uña a medida que va creciendo como si fuera aceite de cutícula para que la nueva uña que crece esté fuerte!! Es lo mejor del mundo y lo recomiendo 100%!!!

Si me funciona y a mi hija también! Es costoso pero vale cada peso, puedo traer las uñas desnudas y hacer cosas en la casa y sin maltratarse antes no podía tenerlas descubiertas ni un día sin que se partieran o abrieran en capas, mis uñas eran frágiles y delgadas ahora están súper sanas :) Si tienen dudas no lo piensen ! Nadie me pagó! Jajaja solo que ningún endurecedor del mercado o métodos caseros me habían ayudado .

Tolles Produkt - habe es erst als Kur nach Anleitung verwendet (sogar etwas länger) & verwende es nun immer vor dem Nagellack; meine Nägel sind gesünder und gehärteter. Hatte vorher das Problem dass sich in den Längen die Nägel gespalten haben und das Problem ist seit der Kur deutlich besser geworden & kaum noch vorhanden
