I have a new hair care product that has the 12M symbol on the back. I know what this means and was wondering, do I literally only have 12 months to use this product after it has been opened? The product is stored in a opaque white plastic bottle and the lid looks to me like an integrated, non-removable pump.
Here’s a photo of the bottle (from Google images) to show what I mean:
Hey Scott. The PAO is more of a guideline than anything else. Within a year there’s little that will go wrong with a product like the one pictured. Hair care products are typically stability tested to last about 3 years, maybe more.
Of course if you notice any bad smells or see any bacterial growth, throw it away.
The picture you sent is just the front of the bottle that just tells me the product name. To be honest I can’t tell much from that but if it’s the same product as we discussed above then I’d expect the same information would apply.
One thing I just thought of: It looks like this is not a pump dispenser so the package MAY not protect the product from bacteria as well. Not a huge concern though.
