Customers say
Customers report that the nail serum improves strength within the first week and works effectively within a week. The product receives positive feedback for its appearance, making natural nails look nice, and customers find it worth buying. However, experiences with brittleness, peeling, and splitting are mixed – while some say it stops these issues, others report continued problems. The drying effect is also mixed, with some noting it dries in a minute while others find it causes dryness.

Itâs me! –
Saved my nails!
TLDR- GET THIS!!! It worked for me w/consistency and patience. Product is a watery consistency and dries fast!My nails had become thin and brittle, so my solution to keep them from bending and breaking below the free edge constantly, was to start keeping them coated in builder gel and UV gel polish. That worked great for a few years, but my nails were in desperate need of a break from having them constantly polished.Once all of the gel polish was off I knew I was in trouble. My nails were now beyond thin, they were paper thin and peeling. The slightest touch would bend them. It was painful. I couldnât even scratch myself. And of course, when you know you canât scratch, is when you become the itchiest human ever. It was torture. All of my nails actively hurt.So I went on the hunt for something that could help. I eventually settled on this OPI Repair Mode. It arrived and I started using it immediately and religiously. Twice a day, every day. Without fail. I had reminders set on my phone to be sure I didnât forget (thanks, ADHD!).The product itself is thin and watery. Not at all like nail polish. And you donât have to have a steady hand to apply it. Just slop it on, wait a minute or so and go. Super fast and easy!The first month of use I would go back and forth with myself trying to figure out if it was working or not. It was definitely working some and my nails had become less painful, but I still couldnât scratch any itches I had. My nails were still thin and breaking, even though I kept them as short as possible.Toward the end of the second month is when I finally knew progress was being made. My nails werenât peeling or painful anymore. And I was able to lightly scratch my itches again. Finally!!After a solid 2 months of use, I decided to cut down to using the product once a day and start incorporating revitalizing cuticle oil (I used Cuccio that I found here on Amazon) into my nail rehab routine. I would use the cuticle oil on my nails and the surrounding skin (rubbing it in as much as possible) in the morning and usually at least once during the day, then at night Iâd put on the Repair Mode. I did that for a couple of weeks, then stopped using the Repair Mode altogether.Now I just use the oil a few times a day without a schedule or reminders. Just whenever I remember or feel like my nails are feeling extra dry. Itâs been about 3 months now and my nails are almost back to what Iâd call normal.I really hope this review helps anyone who was in my shoes. Itâs not fun to have painful, bendy, peeling, breaking, nails, but there is hope! I hope this works for you like it did for me!!

It Actually WORKS!! My Nails are Growing!!
Iâm a 42 year old female that finally found THEBEST nail strengthener/growth product Iâve used and that saying somethingð¥³. Took long enough. My nails were always paper thin after years of acrylics, gels, gel x, etc. they wouldnât grow and they would bend in the wind. I remembered I had bought this product awhile ago and decided to give it a whirl. 3 weeks later and I have stronger and longer nails than Iâve EVER had before. They arenât breaking. I even have one nail that has a crack all the way down the bed. It would always break when it got to a certain length because it would bend. Now that nail is growing.The instructions say to use it 2 times a day, i did use it more. 3-4 actually.

finally a product that worked !!!
At 64, Iâve had nothing but horrible, splitting nails all my life, as did my mom. Tried everything from supplements to topical nail repair products by the dozens. THIS WORKED! Finally, I can say after 2+ months of use (I waited to review to be sure!) that this product actually does make brittle split- prone nails stronger. My daughter even commented recently about my nails since sheâd never seen me have decent nails before ! This is worth it. Easy to use and definitely healed my nails !

Pricey but good!
Works well so far! I’ve been using it on my nails (which are paper thin) for about a week now, 3x a day. It’s definitely helping with the sensitivity of my nails, but can’t say much about growth. It is a little pricey in my opinion, not a miracle product or a cure all. But it definitely helps in combination with other nail strengthening products.

THIS ACTUALLY WORKS!!!
Ok let’s face it. I was totally skeptical that this would repair nail damage. I mean come on. How many times have we purchased something, only for it to wind up in the trash and the money down the drain. THIS STUFF WORKS!!!I damaged one of my nail bed with years of acrylic, gel and nail “Dip powders” pretty severly. Half of the nail grew at a normal rate and the other half did not. It also had a vertical crack that would not quit, and caught on everything. It was very painful. I had given up. I have been using this for about a month at this point. The nail is growing at a more normal rate. The overall split is virtually gone. I do still have a small divot in the tip of the nail, but it is no longer an actual split in the nail. Just a spot that grows a little slower. I had 2 other nails that were beginning to grow unevenly and they are fixed. I am a daily user of this product. No, I do not know what will happen if I stop using it. I don’t think I want to find out.

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 dolÃa 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 dolÃan mucho, asà que probé a usar builder gel para protegerlas y ya no me dolÃan. Cuando pensé que me habÃan crecido lo retiré completamente y seguÃan 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 dolÃan solo con verlas a poder tocarlas y sentirlas más fuertes. Solo con el primer uso me sorprendió porque ahora podÃa limar mis uñas naturales sin llorar del dolor. Ahora llevo ya usándolo durante los 6 dÃas que promete que hace efecto, siguiendo las instrucciones de ponerlo 2 veces al dÃa 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, asà 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. IncreÃble!! 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 cutÃcula para que la nueva uña que crece esté fuerte!! Es lo mejor del mundo y lo recomiendo 100%!!!

I am 74 years old. Never had good nails because of the medication I take. In one week of using OPI Repair Mode I noticed a big difference. Itâs now 4 weeks since I started using OPI Repair Mode my nails are smoother, stronger and I havenât had to wear any coloured polish to hide the nail lifting. Love this product.

I think this is an underrated product to some degree (about 4.1 stars as of now). It DOES work, but… not really in 6 days. That said, nail growth is so slow and small that it would be hard to tell if there was growth in 6 days.I had very damaged nails from poor care – spraying my plants with rubbing alcohol solution with no gloves was probably the biggest culprit (thanks thrips), but there was other neglect too. I’m really into nail wraps, so nails that broke were replaced with a press on until they grew out. The fake nails or glue was never removed properly. Eventually I had so many breaks and damaged nails I realized I had to start again. It’s been agonizing waiting for them to grow so I can do nail wraps again.If you use this serum, scrap the nail polishes that help your nails grow (they did nothing for me) and use this + nail moisturizers. I used this 2 to 4x a day – never less than 2 – from April 18 to May 1. The pictures show the growth in just under two weeks. Nails grow around 3mm per month. My middle finger on my left hand has grown about 2mm. That’s tracking faster than typical growth. My index finger on my right hand only has about 1mm over the same time period. It’s stubbornly slow.So did this serum help speed up growth? Are my nails stronger?Maybe. It definitely didn’t hurt. If nothing else, it made me feel like I’m doing something to fix the situation, and that’s likely just as valuable lol.I don’t think there is any product that can really make your nails grow faster/thicker, but I’ve also learned there is no single, silver bullet answer to fixing damaged nails. It requires a lot of routine changes and products. If you’re born with weak, bendy nails, like me, the effects last only as long as you use the product(s).***important: During this time I also used KUR Londontown Nail Restoration cream and Healthy Hoof + cotton gloves at least when I go to bed. I created an entire nail care regime that is, frankly, exhausting. But I miss my nail wraps so much, it’s worth it.

Très bon produit, jâai commencé à voir une amélioration après 15 jours dâutilisation en le posant 2fois par jour. Au bout dâun mois mes ongles sont plus solides et étonnamment plus lisses jâavoue que je nây croyais pas, certains onglesplus abîmés sont encore striés et se dédoublent , jâarrive à la fin du flacon et je vais en recommander malgré le prix excessif mais vu le résultat encourageant je vais refaire une cure

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 itâs 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 couldnât 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 Iâm 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 Iâd 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 Iâm 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 arenât 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 Iâm applying this product intermittently to maintain the continued support to new growth of my undamaged natural nails, Iâll 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 itâs now 19th Oct so itâs 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 Iâve 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 Iâm not applying this Opi product daily any more but want to keep my nails, cuticles and nails edges hydrated and healthy. Iâm 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. Iâll not pay £29 for this no matter how good it is, when Iâve previously been getting it well below £20 the past two times Iâve bought it here. But if youâve the money, donât 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% canât recommend this Opi product enough.
