Seeing darker lines or the black spots on your nails could be signifying a variety of health conditions. Most people ignore it when they see their fingernails like this because it isn’t painful or discomforting. The darker lines might signify a higher rate of melanin production or fungus growth beneath your nail. If your nail looks like this, you should see a doctor because serious health issues may be going on as well. You may have psoriasis or even melanoma, an aggressive-type of cancer that is attacking the skin under your fingernails.
