What increases my risk for onychoschizia?

Your risk for onychoschizia is increased if you frequently wash and dry your hands. Onychoschizia can also be developed because of frequent nail treatments with harsh chemicals. Conditions like tuberculosis, Sjogren syndrome, malnutrition, and psoriasis can also increase your chances of developing onychoschizia. Since onychoschizia is sometimes linked to the X chromosome, women are often more likely to develop the condition.
