Hand eczema might be messing with your nails. Ridges on the nails and misshapen nails can occur with hand eczema. The inflammation from the eczema can disrupt the connection between the cuticle & the nail plate, allowing debris to enter the nail matrix & interfere with nail growth. Triggers for hand eczema include frequent hand washing, harsh soaps, wet work/doing dishes by hand, & contact with nickel. Avoiding triggers & protecting the hands with gloves is key for preventing flares. Moisturizer
