What's the best way to treat a nail fungus?

Laser treatment: There are many topical treatments which are virtually ineffective. Oral medications can have serious side effects and have to be monitored with regular blood tests. Find a podiatrist that performs laser surgery as the success rate is very high with no ill-toward side effects.

Tough/long to treat: Toe nail fungus (onychomycosis) is rather difficult to treat and often requires 3-4 months/cycles of medication and may take 6-8 months or longer to get a "new/normal" nail. If only one nail involved, removing the nail maybe a better option. Recurrence is common, unfortunately. Consult your doc for a best treatment option for you. Good luck.

Not guaranteed.: The reason you hear so many different treatments for toenail fungus is because there is no perfect, sure-fire treatment that works 100% of the time. I've seen natural oil remedies work, but rarely. You can also try laser therapy, antifungal creams, paints, or even oral medications if your doctor deems you healthy enough to take them.
