Way back in the day, I used to get acrylic overlays on my nails. I stopped after a short time because I hated the damage to my natural nails, but during this time frame I noticed that as my nails grew longer, they curled at the edges of the tips, eventually pulling away from the acrylic. My tech called it "tunneling."
Thing is, my nails still do it, and I'm wondering why. I attempted to get a photo of it tonight, although I'm not sure if it is adequate. Left thumb:
The nail itself is this length:
I wonder if there's something I can do to prevent this. It isn't unsightly, not yet, but if I don't trim soon I'm really going to notice it, and not just on the thumb. I'm not sure if you can see it starting on the rest of my nails:
Maybe there's a sort of event horizon with nails. A maximum attractive length, something. I know my nails will grow longer than this, but I'm at my PERSONAL max in terms of usability -- I'm constantly having to be careful with things, because about now is when they get a lot more fragile. (Mad-Eye Moody Moment(tm): Constant vigilance!) But it isn't only the fragility issue here -- it's also this curling thing I got going. I esp. notice it on thumbs, of course, and on both middle fingers. But it's starting on all of them, just not as noticeable yet.
