You're using a toxic nail polish If you're having nail problems, there are three chemicals commonly found in polishes that you should avoid: toluene, dibutyl phthalate (DBP), and formaldehyde. "I have patients come in all the time thinking they have a fungal infection, but it's not -- it's actually damage from commercial polishes," says Spielfogel. "These polishes strip all the moisture from your nails and cause discoloration."
Try swapping out your regular polish for a "healthier" brand like Butter London, Zoya, SpaRitual, or Dr.'s Remedy Enriched Nail Polish, $17, which Spielfogel co-created. "It has vitamins and nutrients to help keep your nails healthy," he says.
