I was just wondering if anybody knows how to find the expiration date on relaxers. How are we supose to know if the relaxer is already outdated, or how long its been sitting around on the bss shelf? I know I have had a bad perm before probaly due to it being old as crap! But how can you tell other than smelling it before you buy it that the relaxer may be expiered. What if its the boxed relaxer, you can't smell that until you get ready to mix it up. If anybody knows how to find the expiratio date on relaxers let us know!
