OPI

 Repair Mode Bond Building Nail Serum

I got this after I had some fake nails damage my natural nails a bit. I have thinner nails that I've worked very hard to strengthen and maintain over the years. After using this, my nails started peeling like never before, splitting at the top and flaking. I feel like it set back my nail progress a lot. Really bummed!!! My sister really likes it when she uses my bottle so I'm giving it to her.

My nails look and feel so much better than before I started using this product

I got extra's for holiday gifts, After I tried it and my thin, week nails changed. I have heard from the recipients and they are as impressed as I was.

A co-worker of mine purchased this for me after I was complaining about my nails constantly breaking or chipping now that I've grown them out. I can't even remember the last time I didn't have at least one broken/chipped nail! I wanted this to work but after my own experience and research, I've decided to stop using it to prevent any damage. I have used keratin treatments before on my nails (my favorite being CND's Rescue RX) and while most of them all feel pretty similar, I noticed OPI's had a much different feel to it. Usually after applying a keratin nail treatment and has been fully absorbed, my nails feel sturdier, yet smoother and hydrated. When using OPI's, it felt like it wasn't doing anything other than drying my nails out— sometimes I'd even feel a slight burn. I was using it as directed, twice a day on bare nails. I even had to look the product up because I thought maybe it was actually a dehydrator or something. When I did this, I started seeing handfuls and handfuls of reviews over various different websites and platforms claiming the product had destroyed their nails, with some even saying they experienced severe lifting and/or detachment from their nail beds. 8 out of 10 of those reviews all mentioned having pain that felt as if their nails had been smashed. For me, it's not worth the risk. If you want a keratin treatment, I would go with CND's. It's actually a little cheaper too.

I had done some damage to my nails by doing gels and this stuff has made my nails thicker and stronger. I also had a nail that I had smashed in my car door a year ago, I have been applying this to that nail a few times a day and the nail is finally starting to grow back in normal. Prior, after I smashed it, the nail was very thin and splitting down the middle. I had added an acrylic nail and gels to protect it, but I think that actually made the nail worse. This stuff will now be part of the beauty regime.
