Fungal nail disease, medically referred to as onychomycosis, affects 2% to 14% of the adult population. Fungi that feed on keratin, a structural protein within your nails, frequently cause the condition. Fungal colonies proliferate in moist environments and invade the nail bed by penetrating the margins of the nail. Fungal nail disease may result in pain, impair the ability to walk and contribute to a negative selfimage.

Some prescription medications have side effects and therefore are not always the best treatment option. Another option is surgery to remove the nail; this is not a popular option either. Lasertherapy to treat the disease is gaining popularity as a means to achieve a temporary increase in clear nail.
