After 2 years of Biab, 1 nail was completely green. Have it all taken off. And drip with perioxide and when it was dry, add Heka, when it was dry, Dadi oil. 2-3 times a day, we are now 2 1/2 months later and my nails are almost good again. The green nail was already gone happy after 2 weeks and because of the Dadi oil, my nails are starting to look normal again.
