I bit my nails all my life, but during this lockdown, I've managed to stop it! My nails are fairly long now, so I've been painting them. One thing, though - they are horribly discoloured, a dark yellow/brown, as though they are nicotine-stained (I don't smoke).
I've cut my nails very short during lockdown, for hygiene reasons, and to stop them breaking with all the hand washing. A good scrub with toothpaste (on an old toothbrush) brightens them up. I use O'Keeffe's Working Hands cream every night before bed.
Hi PinkCakes If you always use a clear undercoat first it will prevent the final polish colour penetrating your nails. I’d try cutting half a lemon and rubbing that across your nails for a few days to take the existing stain out. You’ll only need one lemon, just keep wrap it in cling film and keep it in the fridge.
