Someone who specializes in skin has lately provided some insight into the possible meaning of nail ridges and when it’s necessary to see a doctor. According to Dr. Ross Perry, a skin expert at Cosmedics, these ridges may indicate a number of health problems, including inadequate nutrition, lack of water, and even specific skin disorders.
Dr. Perry claims that ridges can be the result of a lack of certain minerals or vitamins. “Nutritional factors like a lack of Vitamin A, or if your body is low on protein or calcium, may lead to ridges forming,” according to him. “In more extreme cases, a severe iron deficiency can cause noticeable changes to your nails, such as the development of ridges”
