Does WEN shampoo go bad?

Good day, I have a question regarding the shelf life of WEN shampoo. As someone who values the quality of their hair care products, I'm curious to know if WEN shampoo can go bad over time. Does it have an expiration date, and if so, how long does it typically last before it starts to lose its effectiveness or even deteriorate? Additionally, are there any telltale signs that indicate when the shampoo has gone bad, such as changes in color, consistency, or scent? I'd greatly appreciate any insights you may have on this matter.
