My Nails Stopped Breaking, Peeling and Bending When I Started Using This Serum
As a beauty editor with weak nails, I put OPI's Repair Mode Nail Serum to the test, and I was so impressed.


I've always struggled to grow my nails. It seems no matter what I do, my nails are destined to break and peel, making it near enough impossible to grow my nails. I'm always looking for nail growth serums and cuticle oils that can strengthen my nails and enhance my hands. And the very best one I've tried so far is, without a shadow of a doubt, OPI's Repair Mode Nail Serum (£30). Scroll on for my thoughts on the nail growth serum, how it works and my before and after pictures. (Even I can't believe how much better my nails look).
OPI Repair Mode Nail Serum
How It Works
OPI's Repair Mode contains a Ulti-Plex technology, which works to repair the bonds inside the nail plate. Think of it as the nail version of Olaplex, helping to strengthen your nails from the inside out. It comes in a serum delivery serum, which you need to apply to bare nails twice a day for six days. It sinks in immediately, so there's no hanging around waiting for anything to dry, and you can also wear it underneath polish. You just have to apply two coats and wait 10 minutes before following up with your usual nail polish or gel polish.
You do need to apply it to bare nails, so for the first six days, it's best not to wear anything on your nails if you can. That being said, you can apply it to regrowth areas as your polish grows out. I applied mine in the morning and just before bed, then after a week, I used my trusty Dior Base Vernis Base Coat (also amazing, BTW) to create a protective layer on my nails if I didn't follow up with nail polish.
Before
These are my nails about three months ago. Tried as I might, I couldn't get them to grow past my fingertips as they were thin and peeling and prone to breaking—even when I was wearing nail polish.
After
This is about two months after using OPI Repair Mode, and as you can see, my nails are so much longer. They feel thicker, and they're less prone to breaking or peeling now. Because they are so much thicker and stronger, the whites of my nails look brighter overall, too. I maintain my results by applying a couple of coats of Repair Mode in between my nail polish manicures, which I will remove every 7-10 days.
Here I'm wearing OPI Funny Bunny and Baby, Take A Vow (inspired by Elsa Hosk's recent engagement nails), followed by two coats of Essie Gel Couture Top Coat. Honestly, my nails have never looked better or stronger. They're long enough now for me to file into an oval or almond nail shape, and the longer length has helped to elongate my fingers, too.
The Verdict
In case you haven't already guessed, I'm totally sold on this nail growth serum. It's so convenient to use. It sinks in quickly and with no waiting around for it to dry. Yes, you'll need to keep your nails bare for the first week or so, but it's so easy to fit into your routine, and it's a great way to strengthen nails post gel manicures or if you want to grow your nails. At £30, it's one of the most expensive nail serums I've tested, but trust me, this really works. There's a reason why this won a Who What Wear Next in Beauty Award.
