One thing that I learned very early on is that oils DO NOT moisturize; but instead work as sealants(sp). Does that go for butters such as cocoa, shea, and avocado? I just think of oils and butters as being in the same catergory, but I am always hearing about the moisturizing properties of these butter? Can butter be used solely for moisturizing purposes or should they be used after a cream or liquid moisturizer is applied to the hair. Thanks in advance for your responses ladies.
