It can go bad, yes. The product is made to have an expiration date, though I'm not positive on the actual length of the shelf life. My best estimate would be 1-2 years. I recommend calling/contacting Global Keratin directly for a more exact answer. If you still want to purchase the product I recommend finding a friend to share it with. The 33.8 Oz bottle has enough product to keep a full-time hairdresser stocked for at least 6 months. For as often as you use the system, I think 10 Oz would be more than enough for your needs, and could also last you a full 2 years (depending on the shelf life of the bottle).Hope this helps.

So sorry not sure about how long it could stay for, best bet call the company and ask that question.

The expiration dates vary but I have ordered this from Amazon for over 5 years and have never had a bottle that had a short expiration date. most recent purchase of it expires in 2016. Hope that helps

We have not ever had trouble with this product going bad, we do use it everyday though. You may want to ask the maker of the product for detailed info about what they would recommend for expiration.

Hi Julia, If you keep this product in it's container or any tightly sealed container it will last for years. Hope this helps you.

Although ours rarely lasts that long, I doubt it will go bad. I don't believe they use bio oils that will go rancid. We found a bottle in back of the closet that was forgotten and at least 2-3 yrs old. It twas still fine. This is a great product and we highly recommend it. Plus it's made in the USA!

I really don't know for sure but I've never had it go bad. I keep it in the fridge in a plastic container after I open it. I use it very sparingly and it seems to last for months. I would imagine it's the same before it's open. hope this helps.

Probably indefinite. As long as it's kept dry there's nothing that can go bad, it's like storing sugar. If you're using it in recipes it won't last long enough to worry about shelf life.

It is good for at least one year, whether kept at room temperature or refrigerated. Each bottle should bear an expiration date.

Each bottle will have an expiration date based on its production date. I have a bottle that has an expiration in 2017. I assume that this means most bottles will last 1-2 years to be safe.

To my knowledge it doesn't expire. I have stocked up also, and have had some bottles for 5 years now, and they still work the same as the day I first used them. This is a GREAT product, and it smells Phenomenal too +++

I've been using the same bottle for about 4 years after opened. Its fermented, it does not go bad. It was created by being aged. I just keep it on the shelf in my cabinet.

Yes. It expires usually a year from the manufacturer date. It also has an expiration date on it. As far as storing it I would keep it at room temperature. I three 8oz bottles that I keep in the cabinet under my tank for emergencies. Like when I once did to thorough of a cleaning and caused a mini cycle. I poured half the bottle in and tank cycled in few hours so I know room temp is sufficient for storage.

I got two bottles, one expires Jan/2014, the other one Sep/2014, I suggest you should get this from Sam's club, they have a later expire data to 2015 and seems cheaper, I have decided to get this from Sam's club if needed.

if you use it as directed the expiration date would not be an issue, kind of hard to answer a question like this as it is constantly being made fresh so the date would always be changing as its made and sold. One of my empty bottles which I bought a year or so ago has the expiration date on the bottom and it is for 05 2015 so I dont think you have much to worry about.

I doubt it. Drugs don't "go bad". The worst that happens is that they lose some potency, but usually drugs have a very long shelf life. Before retiring I spent decades giving anesthesia and back then I used to almost always check expiration dates on vials, but if it had only recently expired, I went ahead and used it and I can tell you that I saw noticeable decline in potency. I am pretty sure that if you get 3 bottles at a time, you will have no problem.

I have had mine for over a year and it is still perfectly usable and works. I don't get sick with taking this stuff. I don't know of any expiration date on my bottle.

There is an expiration date on the bottle if that is what you are wanting to know.
