For me it's four months. And standard size is 6.7 fl. oz= 400 ml here. I dilute it with warm water 1:1.
I don't use shampoo, except for special occations like when I've oiled my hair, or when I've been doing stuff like swimming and stuff and I feel I have salt/clorine in my hair that don't go away with only CO. So I guess 2-3 months normally, 4-5 months when I wash with shampoo every wash.

My answer is skewed due to the fact that mu "average size bottle of shampoo is always around a half gallon, and I wash my hair maybe twice a week if I'm really grimy. Oh and this is old info, because I switched to bars two months ago...

It's so hard to tell because I am never using the same one. I am always experimenting with a different one. But if I had to guess, I'd say three months. Conditioner on the other hand....
Erm, 2 - 3 months I guess. Wash daily with diluted shampoo for my scalp, and then wind up using it on filthy dogs some, and run out of body wash..... I dunno, use it till I forget I don't have any?
I voted more than six months... my current bottle of shampoo is around a year old, and will still probably last me another month. I wash daily, and use shampoo probably 90% of the time, diluted and just on my roots. I think it's an 8 or 9 oz bottle.

If I used only one kind of shampoo I'm sure it would take more than a year. I CO most of the time. I'd guess I use shampoo once every 2 weeks. I always rotate my products so it's only a guess. I have maybe 6 bottles of shampoo going right now and all but one are over a year old. Conditioner gets used up much much faster.

I use a bottle in about a month and a half... depending on how frequently I wash it (when I excercize more, I wash it more), but sometimes a little longer depending on the type of shampoo

I don't really know since I've shared my shampoo/conditioner with my sister almost my whole life. I think I took a new bottle of conditioner with me to college, and I didn't finish it while at school. We'll see if I blow through it faster now that I'm sticking with CO as my basic routine.
