As much as I liked my nails really long, they just were too long to be practical anymore. I took them down a bit, with a nail file. I haven't been doing anything special to them since my surgery in mid-August. I stopped taking Biotin back then.
Here they are after the filing to cut down the length - you can't see it because of the curvature of my nails, but the corners are sharp since I filed straight across. I sat outdoors to file since I was generating quite a bit of nail dust!
I accidentally scraped the nail file over my thumb nail as you can see in the photo below. I leave the surface of my nails alone - no buffing or anything.
And after final filing with the finer side if the file and adding some curve to the corners. They're ready for a quick wash and scrub followed by lotion and on to the next mani!
