This condition of nails may be caused by fungal infection or nutritional deficiency. What is the specific reason? I suggest you go to a regular dermatological hospital as soon as possible to find out the cause, diagnose the disease and treat the corresponding disease.

Suggestion:

About nail deformation, it may be caused by the lack of trace elements. It is suggested that the diet should be comprehensive, take multivitamins in moderation, and not be partial to food. Or go to the hospital for trace element testing.
