I voted 3-4 months, even though I am guessing at how long it will last, but since I only use about a teaspoon a day, I am sure it will last a long time.

Maybe try CO washing with Suave Naturals, and save the AHC for conditioning only? (That is what I do.) I go through the suave faster, but I still have about 1/2 a bottle left, and I have been CG for a month now.
