What to Do About White Toenails

White toenails are usually caused by onychomycosis or white nail syndrome, so when this condition occurs, the first step is to perform microscopic examination to check for fungal infection. If there is a fungal infection, antifungal treatment is required, which can be oral administration of Itraconazole or Terbinafine. Oral medication should be taken simultaneously with amorolfine topical solution applied to the nail area. If the microscopic examination is negative for fungus, then treat according to the principles of white nail syndrome, first check the levels of trace elements and supplement any deficiencies, and locally apply urea-urea cream at the same time.
