OPI Repair Mode Bond Building Nail Serum | Keratin Protein Strengthening

**Update: it's been over 6 months and now I use this every polish change. The results are just unbelievable. I can go without polish, and my nails grow long and strong! It's the first time in my life I can say that. I now combine with hard as hoof cream and regular cuticle oiling and can't say enough great things about how much this has transformed my nails. No more soft spots or bending. Background: 11 years of gel manicures, occasional dip manicures, press-ons, and a recent run of semi-solid gel strips left me with brittle, split, ridged, and overall damaged nails. I almost never have taken a break between polish changes during that entire time. I was using Gemini AI to help come up with a plan to heal my nails, and one recommendation was this product + Nail Envy. I diligently applied this twice a day for 6 days, even taking it with me while traveling. It is a great way to do a forced reset, since you must apply this on bare nails. Day zero before applying I soaked my nails in warm water + olive oil, and I did this again on day 6 before my last dose. I did a full manicure on day 6, cleaning my cuticles with a glass cuticle stick, shaping nails (filing only in one direction!) and gently buffing. My nails looked so much better. My photo is the "before" from the manicure and it is hard to describe what an improvement this is from day 0 (even if it doesn't look like it). I didn't experience any of the nail lifing some people online describe with this product, and overall my nails seemed much more firm with less peeling. I do still have two nails which seem a bit soft in localized spots, so I'm going to get an ISDIN product with silica in it to see if I can correct that while they continue to grow out. I've applied Nail Envy in my "after," and although I don't like the nude color very much I do feel that overall the combo is helping my nails! I'm nervous not having the strength of a gel manicure, but will have to use gloves during dishes and stop using my nails as tools to try and keep them from breaking while they grow out. I'm going to try to go 6 months without gel using Repair Mode weekly with clear Nail Envy polish to recover from all of this damage. I blame myself because I'm not very patient with removing gels and press ones, so most of my damage is from pulling-trauma and acetone. I'm just so glad there is something out there to help my nails recover quickly!

I absolutely love this serum. I had acrylics and of course my nails were extremely damaged after. I was using this daily after and it really helped strengthen my nails. It takes a while for the nail to grow out but the damaged part of nail is strong and not bendy because of this. I’ve hit my nails on stuff and I get no breakage . This has never happened before. You can see at the tip of my thumb were the damage is at this point but again my nails are so much stronger!

Edit: At first I was very disappointed with this product. I used it two a day, my nails kept breaking, even though they seemed to be getting stronger. Finally one day I clicked. I actually had to trim my nails because they were foo long. I couldn’t believe it. The 1st time ever, and I’m 60+. Even well into post menopause my nails are finally fabulous. Strong, hard and even a crack that had run through on nails forever is gone. Still working on another, but it’s healing up nocely. With the cost. Try it. You’ll like it. Just remember to wait a few weeks before you you give feedback. I’m on my 3rd bottle.

I've been using this nail serum for a couple of weeks, and I can already see some improvement. My nails feel stronger and don't peel as easily as before. The serum absorbs quickly and isn't greasy, which makes it easy to use during the day. The only reason I'm giving it four stars instead of five is that I expected faster results for the price. Overall, it's a good product, and I would continue using it.

I accidentally use callus remover instead of cuticle remover and badly damaged my nails. They were peeling and getting dry crack lines from the nailbed to the tip. I used the OPI Repair Bond serum for a week and they are much improved. I do 2 coats once a day and usually one more coat later in the day (I have it on my desk right in front of me). It basically disappears into your nail. I am going to continue using it as the damaged part grows out and plan to use it going forward since I've always had weak nails.

I don’t think it did anything. I used it twice a day for 8 days and this is my before and after picture. Maybe the nail damage is too great to help it, but for $25 I wasn’t impressed. Picture on the left is before and right is 8 days later.

I've tried various products to strengthen my nails, particularly my left middle finger due to nail splitting all the way down to the matrix from over washing my hands due to my occupation. When i say I've tried a plethora of products, i am not exaggerating! Various nail hardeners, oils, biotin supplements, zinc, collagen peptides, gel powders, and even nail avulsion (total nail removal) 😖. I began using this product about six months ago, and noticed a wonderful difference in my nails! They are much stronger, healthier and I do not have to use any nail hardener. I apply in the morning and before bed. I do admit that although it has bot completely repair my split nail (you can see in the picture and video) it does make it much more manageable and I keep it filed very short. You can see how my nail was before I began using this serum in the last photo and how split it was. My nails look clean and I also apply either Dadi's Oil afterwards or Healthy Hoofs nail balm, also available on Amazon. I still take vitamin supplements along with collagen peptides, but I do believe this serum helps significantly. One bottle 🫙 lasts me about 6 to 7 weeks, and that is with application on all of my nails. I am amazed by how quickly my nails dry - in mere seconds-💅🏿 and how I could apply my nail balms and cuticle oils immediately afterwards. It took about 2 weeks for me to see some improvement and about one to two months to see a sustained response. Some folks complain about the price 💰, but honestly, I believe you get what you pay for and you can't place a value on your health! I still feel it is very economically priced given all of its benefits and duration of use. I have recommended OPI Repair Mode to others, including my hand surgeon and I believe she has recommended to her patients as well (after she saw my before and after picture 📸 😆 😃). I say give it a try and if it works for you, then great, and if not, at least you tried it for yourself, but I honestly believe most folks will be pleased with the results! Thanks for taking the time to read my review! 🌟

I’ve been trying to repair damage from years of gel nails and this has become part of my nightly nail routine. I’m still a little on the fence about whether it truly “builds bonds,” but this is already my second bottle so I clearly think it’s helping somewhat 😂 I generally trust OPI products because they usually make quality nail products. I use it at night instead of twice daily like directed because I wash my hands constantly working in nursing and morning application feels wasteful for me. It dries quickly, hasn’t irritated my super sensitive skin at all, and my damaged nails do seem to be improving over time. I’m not sure I confidently recommend it because I honestly don’t fully understand how effective the ingredients are… but apparently I’m repurchasing anyway.

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%!!!

I have tried so many nail repair serums. This one is great it absorbs into the nail quickly. It does take a couple of weeks to notice the difference but with consistent use it really works.

I waited to review this product after using it as per instruction,and waiting for my nails to grow It really works, my nails are strong I like that it is colourless and dries quickly with no smell Worth the money , especially as I don’t need to use it everyday now

This product works but takes time to work. Painting nails in between application did not yield positive results, it dried my nails, mostly just peeled off and some nails separated from the bed - not the fault of the product just to be clear. I expected to get strong and hard nails which didn't happen. I have long very bendy and flexible nails. It does stop my nails from the layers splitting and peeling - yay! The corners, especially prone to peeling, no longer split, peel or separate so don't get caught on things causing them to rip. Given nails grow 3 mm per month and the nail being 10 mm it takes about 3 months to cover new growth. I'm guessing I'll have to buy this for the rest of my life to keep the nails from peeling. Worth it IMO.

Bon produit, OPI toujours aussi fiable. Mes ongles sont fragiles car trop souvent rongés. Une application régulière 2 fois par jour et en une semaine j'ai vu la difference. Agréable à appliquer car non gras et sèche vite, on a pas l'impression d'avoir quelque chose sur l'ongle. J'ai réussi à faire pousser mes ongles. Depuis, j'en mets régulièrement pendant 2 jours entre 2 poses de vernis. Seul point négatif le prix un peu élevé. Je recommande.
