Can bleach turn your fingernail brown?

Yes, bleach can turn your fingernail brown, particularly if it comes into prolonged contact with the nail or the skin surrounding it. This discoloration may occur due to chemical reactions or irritation caused by the bleach. Additionally, if the bleach gets trapped under the nail or in any cuts, it can cause staining or damage to the nail. It's important to handle bleach carefully and to rinse it off promptly if it comes into contact with your nails.
