I love Avocado Oil! It is my favorite oil. I use Elysian Isle's unrefined Avocado Oil and it is a lot better than the kind typically found in health food stores (which are usually refined). I use it as a hot oil treatment and mix it into conditioners for extra nourishment. It leaves my hair sooooo soft and moisturized!
Karezone, I find Avocado Oil to be lighter yet more moisturizing than Olive Oil. Avocado oil is a natural source of pantothenic acid (panthenol) which is why I think it does such a good job at moisturizing the hair. It rinses cleaner that Olive Oil, which tends to leave a lot of residue behind, IMO.
