Nail layering is a manifestation of nail delamination disorder, also known as nail peeling disorder. The causes of nail peeling are complex and multifactorial, but most of them are due to the lack of moisture in the nails, which leads to dryness and thus nail layering, which occurs mainly in the free edge of the nail. In addition, there is also a lack of micronutrients in the organism, resulting in the inability to nourish the nails, which leads to the layering of the nails, mostly due to a lack of calcium. In addition, there are also fungal infections that form layering of the nails. Fungus infects the nail and then erodes the free edge of the nail, causing some damage to the cuticle on the surface of the free edge of the nail, which results in layering of the nail.
