Possible causes include vitamin deficiency, trauma to the nail bed, psoriasis, alopecia areata, and Reiter Syndrome, as stated by MedGuidance .
Nail pitting often appears as small pin prick, or circular dents in the nail. There may only be one or two or a large number of these dents. The cause is a loss of parakeratotic cells in the nail plate, as stated by DermNet NZ. Health conditions indicative of this particular type of denting are psoriasis, eczema, reactive arthritis and alopecia areata.
Some health conditions can produce two or more types of nail imperfections, such as psoriasis. The appearance of minor imperfections is not usually something to worry about. However, more serious or chronic nail pitting and dents should be examined by a doctor.Learn more about Nail Care
