Is acrylic causing curling nails?

The curling upward of the nail could be a reaction to the long-time use of the acrylic product. Therefore, despite the fact that the client would like to keep the artificial nail on, I recommend against that. At the very least, you should remove the acrylic from the affected thumb and allow for a reasonable period of time to see of the distorted nail corrects itself (about 4-6 weeks), which it very may well do if the problem is related to the acrylic. If it does not improve then there are two possibilities. One is that there is some scarring in the nail bed as a result of the long-term use of the acrylic, or it’s a completely different problem unrelated to the acrylic in which case a dermatologist’s evaluation should be sought to determine the cause of the distortion. I don’t think that it’s a good idea to cap the nail with acrylic because if the problem is related to the acrylic product, this will cause the condition to worsen. -- The Nail Doctor
