Feb 08, 2010 - I don't know what this stuff is, but it's not a leave-in or anything close. I was searching for a Kiehl's product to replace their discontinued Leave-in Conditioner with Panthenol & Coconut Oil. I bought this before I knew anything about lanolin, but several of its ingredients are variations of lanolin. It just left my hair dry and stressed out. For 4Bs, I find that the Hair Conditioner Grooming Aid Formula 133 is a more suitable replacement for their discontinued leave-in.
