It works. Wish I'd done it sooner!
I’ve been struggling with my L big toenail for years as it wants to curve into my skin, and seems to be narrowing. Even with shoes on, the weight of my dog stepping on my foot (or my toddler) causes excruciating pain. I checked with my podiatrist, who suggested a surgical fix that sounded more painful than I cared to try. And all he’d be doing is narrowing the toenail permanently. It’s already so narrow, it looks funny. So after doing a bit of research, I found Curve Correct—but balked at the price. I tried some off-brand strips, but couldn’t get them to stay on as they were too stiff. In checking with CC, I discovered that they sell strips at different tensions, and with my high curvature, I needed a step below the “normal” tension strip. It took me 2 tries to get one side to stick. (They are serious about too much glue. It won’t stick. If you put the correct amount on, the glue will be almost flat. If you see a drop shape of glue, touch it with the edge of a paper towel to soak up the excess. Also, make sure you prep the nail as instructed. )
Because my curve was so severe, I had to put the strip farther down (about the halfway mark). I didn’t think I’d notice relief right away, but I did. After a couple of weeks, I then added a second strip between the top of my nail and where the first strip is glued. So two strips. While I can’t really tell if the nail curve is actually lessening, or if it’s an optical illusion due to the strips glued on it, I know the pain is gone. I plan to order the refill strips the next step up, and when these two fall off, will up the tension, aiming to correct the curve as it grows.
All that being said, I have some tips. The corners of those little plastic tips are sharp, and some reviews mention them catching on clothing and sheets, causing them to pop off. I used my toe nail clipper to cut off and round the corners, then used a metal nail file and sanded the now rounded ends until they were smooth, and there were no sharp edges to snag cloth. You’ll have to be careful doing the second edge if you plan to do this as it is glued onto your foot. Me, I measured the length I’d need (a strip of paper cut to same size as your strip works as a measuring aid—and is much easier to maneuver over a rounded nail, and cut to size, than trying to bend plastic over it). Once I had the proper length, I used the paper strip to cut the plastic, then rounded both ends prior to gluing. Worked brilliantly, no snags to ruin my expensive sheets or socks. I'm going on one month with the first strip holding strong (2nd strip is only at about 2 weeks. First attempt to glue failed, so followed instructions, re-prepped nail, sanded glue off, used the clean side, and voila, stuck like it should). 10/10 highly recommend.
