OPIRepair Mode Nail Polish Nail Repair and Strengthening Vegan Formula, Patented Bond Building Nail Serum Repairing 99% Of Nail Keratin, Professional Nail Strengthener for Damaged Nails, 9ml

An exceptional nail care product. Although you think it's an expensive item (and it is), I believe that if used according to the directions given, it really helps to strengthen the nails: it has certainly helped mine. It's unbelievably easy to use, although be warned that if you happen to chew or pick at the skin around your nails, if this gets onto damaged skin it might sting a bit! Use it twice a day for 6 consecutive days - set an alarm on your mobile if you think you'll forget.I will be treating my nails with it regularly in future and buying it again when it runs out. I'm very happy I invested in it.

I wrecked my toenails by leaving a gel pedicure on for too long and my nails were breaking and peeling. I bought this about a month ago to try to rehabilitate my poor nails. I’ve been alternating between applying this twice daily for a week then wearing some strengthening nail polish for a week and my nails are recovering. I’ve been using it on my fingernails too (which weren’t in the same mess but have always broken easily) and they are in the best condition ever and don’t seem to beak as easily.It’s expensive and goes on like water (I thought it would be more like nail oil) but I think it is helping my nails and is worth trying if you have problem nails.

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.

This really works. My nails have been weak and flaky for years and nothing I’ve tried has made any difference until I found this product. Within a week my nails felt stronger and look so much better. No hesitation in recommending it.

Didn't do anything for my nails and I noticed them lifting from the nail bed more and my polish not sticking. Would reccomed just sticking to a nail strengthener polish made for soft peeling nails (not hardners)

As a professional Beauty Therapist and Nail Technician since 2002, I've found that no product has significantly improved the treatment and repair of damaged nails based on my training and experience. Typically, damaged nails just had to grow out. Despite this, I must admit I don't take great care of my own nails. They look beautiful when done, but a week's work leaves them scratched and scruffy, leading me to bite off the gel on my days off, which is very harmful to the nails. After repeatedly doing this, my nails became thin, sore, and prone to breaking. Opting for a natural look during a busy summer of gardening and decorating, I sought a treatment that would truly help. Skeptical at first, I tried a new product on the market claiming to repair damaged keratin, the substance that makes up nails, skin, and hair. Despite mostly negative reviews, I found the product to be outstanding. Applied twice daily for a week or up to 14 days if necessary, it visibly improved my nails, making them grow out stronger. Although damage may still appear, the nails remain robust as they grow past the free edge, avoiding the usual breaks and splits. For optimal results, I recommend keeping nails short during growth. The product advises against contact with surrounding skin, which I accidentally did, causing the skin to harden as well—something a manicure and nail oil easily fixed. This incident, however, confirmed the product's effectiveness; if it hardens the keratin in the skin, it certainly hardens the keratin in the nails, as evidenced by the results.It is on the expensive side, but if you are having a break from salon manicures, then this is an excellent investment for your nails in the meantime. I usually buy it on Subscribe & Save as it works out a little cheaper. I've recommended it to so many clients over the last few months and everyone of them has seen results.

Awful. Have given up on this product. Like some other reviewers, it’s caused problems with my nail beds and my nails now have ridges when they didn’t before.My nails split easily and are weak.Don’t bother!
