I just found a shampoo and conditioner that I had stashed away for a while (probably close to 2 years woops)...and I'm wondering, does shampoo go bad? How do I know if it's expired?
I have the same question - I bought several liters of Redken shampoo and conditioner because had double , triple promotions and i wanted to stock up, believing it didn't expire. At the bottom of each bottle is an icon of a jar with the lid opened and ajar, indicating that the bottle had been opened. next to that , it says "24" meaning the product is good 24 months after opening. That icon is on most cosmetics and the numbers vary from 6 to 9 to 12 and on up to 36 , I think, depending on the product and the ingredients within.
Buut my question is this: I haven't opened these products, which implies that they have a minimum of 24 months left. the 24 months begins once I open it. but there's no foil under the cap - I think it's getting or could get oxygen. please help! Should I start giving these a away? I have about 30 liters ( I thought I was saving so much money!)
