what is the expiry date for both the shampoo and conditioner ?
71027
I read somewhere that shampoo and conditioner can last for 2-3 years. I have had the same bottles for going on 3 years and they seem unaffected by the age. As a guy with short hair, I don't feel a need to shampoo it every single day.

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.

The expiration date is usually on the box itself... You will also know by the smell if you are familiar with their products. Fresh and clean vs. no smell or an odd, unclean odor... If you must know, call the dermal institute and give them the code on the bottle... Hope this helps!!!

The shampoo 10oz, conditioner 5oz and the foam 3.3oz. The shampoo I am still using the same bottle and it it going on 3 months but I have short hair. Conditioner I finished about 2 weeks ago and still have 1/2 the foam. Pretty decent really

I didn't look for an expiration date on the product however I did used it and it worked great.My hair is much softer and no freez.

I never thought about the expiration date since it is really just a shampoo. I have had mine for over six months. I bought the gallon size and only use it before shows in the rainy months.

I don't believe there is any expiry date. In my experience, the product remains effective even if it ages to the point of becoming a bit dry (although it rarely lasts that long).

It comes with the smoothout perfection treatment which is the only product that works on my hair and lasts at least 3-4 months, shampoo and conditioner. The product is fantastic.

Both the shampoo and conditioner contain sulfates. Wish I would've check for ingredients online before buying.

I would say it lasts as long as a shampoo bottle. I've probably had mine for about 2 months and I'm about halfway through the bar. My hair is long, goes down most of my back.

Yes indeed, you get the complete treatment (shampoo, conditioner and tonic) good for nearly 2 month everyday use... (short hair!)

Hi Jenny,Don't worry for too long. I've read Regenpure is coming out with a conditioner to complement their shampoos.

It lasted a while, I think two months. I don't wash my hair everyday, I shower daily! Plus I use other hair products. Research the product, sometimes it's better to buy from the actual website itself. I paid $30 for mine with shipping. Wen sells like a whole kit for like 38 dollars.

I am not sure the shelf life, but it will last at least a month you dont need to use a lot. All you need is enough to wash your hair. Rmember that this shampoo doesn't havr sulfate which is what makes a thick lather. At first, it vseems like youll have a lather but as you rub it , it goes away. My hair feels better and healthier.

Mine was $85.00 from 298 BEAUTY SUPPLY and it was both shampoo and conditioner. Great value!

There are 3 bottles in this collection, one each of shampoo and conditioner (5.1 oz.) as well as a foam "leave-in" treatment (3.4 Oz.). They are meant to last 30 days, using them once a day. This variety is safe for color treated hair.
