I noticed my Hair Milk seperated after leaving it overnight in my toasty warm bathroom. I tried to shake it to get it mix but to no avail. The more I shook it the more it resembled Chinese Egg Drop Soup. I then remembered someone who made up a concoction and warmed the products up to get them to blend so that's what I did. I pour it into another container and nuked (microwave) it for 45 second, used a fork to stir it until it blended back nice and creamy again. It's now more than 8 hrs later and it's still good to go.
