It is not recommended to freeze and reuse hair dye, as freezing can alter its chemical composition and effectiveness. Once opened, hair dye should ideally be used within a certain timeframe for the best results. Additionally, some dyes contain peroxides that may degrade after being frozen. It's best to mix only what you need for each application.
