Review: Kiehl's Olive Fruit Oil Deeply Repairative Hair Pak

I received samples of this when I bought Kiehl's Olive Fruit Oil Nourishing Shampoo. It's a hair mask, and it's very effective; it made my hair look glossy and professionally styled, on days when I hadn't even blow-dried. I tried it with the shampoo alone, and with the shampoo plus Kiehl's Olive Fruit Oil Nourishing Conditioner. I preferred the results with the shampoo alone; this plus conditioner may have been too much. I considered buying a full size, because it really worked very well, but I don't think I need super-pretty hair all that often. Also, this can be a pain to use – you put it on after the shampoo and before the conditioner, and you have to wait at least three minutes for it to sink in. Not worth it to me.
