Onychocryptosis can result from which of the following?

Onychocryptosis, commonly known as an ingrown nail, primarily occurs when a portion of the nail grows into the surrounding skin. This condition can often be exacerbated by improperly fitting footwear, which puts excessive pressure on the nails and encourages them to grow inward. Thus, excessively tight shoes can lead to distortion of the nail and surrounding tissue, greatly increasing the likelihood of developing onychocryptosis.

While weak nail structure, improper nail polish use, and frequent hand washing may affect overall nail health or appearance, they do not directly contribute to the condition of onychocryptosis in the same manner as tight shoes. Nail structure usually pertains to brittleness or flexibility rather than the growth pattern causing ingrown nails. Improper nail polish use typically involves aesthetic issues rather than physical nail growth, and frequent hand washing is more associated with nail hygiene and moisture levels than with developing an ingrown nail.
