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! Review: Buy it! I need a second bottle - 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! ## Features - 99% nail keratin repair when used as directed - 94% protection from damage - 4x stronger nails in 6 days when used as directed - Cap made with PCR - Vegan formula, *No animal derived ingredients or by-products ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BXFM8CWF | | Best Sellers Rank | #4,373 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #12 in Nail Strengtheners | | Brand | OPI | | Brand Name | OPI | | Customer Reviews | 4.2 out of 5 stars 7,407 Reviews | | Item Form | Liquid | | Item Type Name | Nail Treatment | | Item Weight | 0.02 kg | | Liquid Volume | 0.3 fluid ounces | | Manufacturer | OPI | | Manufacturer Part Number | NT200 | | Model Number | 99399000051 | | Number of Items | 1 | | Size | 0.3 Fl Oz (Pack of 1) | | Specialty | Protein, Repair | ## Product Details - **Brand:** OPI - **Item Form:** Liquid - **Item Weight:** 0.02 kg - **Liquid Volume:** 0.3 fluid ounces - **Specialty:** Protein, Repair ## Images ![Repair Mode Bond Building Nail Serum | Keratin Protein Strengthening | Nail Strengthening Treatment | For Stronger Nails & Nail Growth - Image 1](https://m.media-amazon.com/images/I/41DM17nhpzL.jpg) ## Questions & Answers **Q: What is Ulti-Plex Technology?** A: Ulti-Plex Technology is Patented, breakthrough technology that allows Repair Mode serum to penetrate the nails, interact with nail keratin, and create new bonds. **Q: How does Repair Mode repair broken keratin bonds?** A: Repair Mode repairs from inside via biomimicry of nail’s natural keratin.

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! ### ⭐⭐⭐⭐⭐ Fantastic! 1st time in my long like my nails are strong. *by S***T on February 24, 2026* 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. ## Frequently Bought Together - OPI Repair Mode Bond Building Nail Serum | Keratin Protein Nail Strengthening Treatment | For Stronger Nails & Nail Growth - Nail-Aid Keratin 3 Day Growth Nail Treatment & Strengthener, Clear, 0.55 Fl Oz - Onyx Professional Hard as Hoof Nail Strengthening Cream with Coconut Scent, Nail Growth & Conditioning Cuticle Cream Stops Splits, Chips, Cracks & Strengthens Nails, 1 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/523701329-repair-mode-bond-building-nail-serum-keratin-protein-strengthening-nail](https://www.desertcart.us/products/523701329-repair-mode-bond-building-nail-serum-keratin-protein-strengthening-nail) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-07*
