Greenies
A green stain under the nail from bacteria growing in a lifted pocket.
Pseudomonas, not mould, and it is on the plate rather than in the finger. The product has to come off, the nail is cleaned and left uncovered, and the colour grows out over weeks as a stain.
A salon that paints over one is hiding it, not treating it.
Also called: green nail, pseudomonas
