FAQs

Answer: (iron deficiency) Vertical nail ridges, which run from the cuticle to the tip of the nail, are fairly common and can have different causes. They can occur when nail growth is uneven which may be a sign of injury or poor nutrition, specifically iron deficiency. On the other hand, heredity may play a role. Gentle buffing can minimize ridges. Try China Glaze Ridge Filler, a smoothing base coat that fills ridges to provide an even surface for manicures.
