I always buy the enormous liter-sized jugs of the stuff. It's excessively expensive, but then I only have to buy shampoo about every 1.5 years.
Since I was running low, I decided to buy some more before returning to Switzerland. Only to discover Aveda no longer carries it!!!
Now I am experimenting with the replacement for extremely dry hair, a rather unimaginatively called "Dry Remedy Shampoo and Conditioner." It has something called Buriti Oil in it. Never heard of it. Is it as good as Icelandic Moss??? Only time will tell.
And, they don't carry it in the liter jugs, which means I will have to figure out where to buy it more frequently.
I like change. I really do.
Just not when it comes to hair care products...
