Kerastase Bain Shampoo 8.5 oz & Fondant Nutri Thermique Conditioner.
When I received the pair in the mail I thought, "that isn't going to last me the whole month, especially the conditioner." I have thick, long hair that is course and slightly wavy, so after a few days of using a cheap conditioner I can barely get a comb through it after washing. The conditioner ran out a week ago, but I still have some shampoo for a couple weeks tops. I expected the bottles to be bigger for that price, but I don't work with measuring cups or in a scientific field where I would remember how little 8 ounces actually is. It's nice, but too expensive, hence only 4 stars rather than 5.
