Green Nail Syndrome Treatment

The stain lives inside the nail plate, so you cannot scrub it out. It has to grow off with the nail. Start by trimming the detached portion of the plate back to where it is still firmly attached; that lifted pocket is exactly where Pseudomonas is living, and no drop or soak reaches it while the pocket stays sealed. Then soak the affected nail in dilute bleach, about one teaspoon of household bleach in four cups of water, or a one-to-four white-vinegar solution for five to ten minutes twice a day. The colour usually starts shrinking from the base within one to two weeks as fresh nail advances. If it has not improved after about four weeks, or the lift is large, a clinician can trim the plate back further and may add topical antibiotic drops. What you must not do is paint over it: gel, polish, or a fresh press-on traps the moisture Pseudomonas feeds on and resets the clock.

Green-nail treatment is a patience exercise, not a one-night fix. The bacteria are gone long before the discolouration is, because the pigment is locked in the old nail and only leaves as the nail grows forward, roughly 8 to 12 weeks for a fingernail. Keep the area genuinely dry the whole time: skip long soaks, wear gloves for dishes, and blot after every shower, because any return of trapped moisture lets the colony re-establish in the same pocket. Leave all artificial nails off that finger until the bed is clean and the lift has grown out, and do not reach for antifungal tablets, since they target fungus and are wasted on a bacterial colony, which is the most common reason home treatment stalls. If more than half the nail is involved, the skin around it goes red or swollen, or you have diabetes or a weakened immune system, get it looked at rather than treating blind.
