Kiehl’s addicts a) don’t travel without their Kiehl’s, and b) never want to waste a drop of it. We often find that while those generic mini-containers you can get to transfer shampoo into are a good idea, we end up wasting the product in the process (it spills over the sides and there’s residue left in the bottle). That’s why we figure that stocking up on Kiehl’s mini-sized goods is actually more resourceful in the long run. Rejoice! You can get all your favorite of the brand’s basics—Amino Acid Shampoo, Creme de Corps, Olive Fruit Oil Nourishing Conditioner—in perfectly portioned 2.5 oz. bottles or tubes.
