It's incredibly hydrating, largely because of the African macadamia oil, which has a molecular composition that's similar to the lipid layer of human hair. (Translation: it absorbs really well.) I like to use a small amount on my ends before I blow dry my hair, and I rub some between my palms and use it to smooth flyaways and frizz after it's dry. But I really, really love to use it as a treatment. I apply it to dry hair, let it sink in for 20 minutes and then wash it out. Tada! Soft hair for days.
