When does henna tatto paste go bad?

Henna tattoo paste typically has a shelf life of about 1 to 2 weeks when stored in the refrigerator, but it can last longer if frozen. Signs that henna has gone bad include an off smell, discoloration, or a change in texture. If the paste has been left at room temperature for an extended period, it is best to discard it. Always check for freshness before use to ensure the best results.
