The Beginner's Guide to Making Haircare at Home outlines how to correctly prepare aloe vera for both haircare and food purposes. You can download this document underneath the Mission 8 and 12 videos! Because aloe vera isn't considered a supplement, there is no recommended daily allowance. You can treat it as you would any natural food, though we do recommend a gradual incorporation just to be sure you have no sensitivities. For fresh aloe preparations, same as you would do with your food, keep any leftovers in the fridge and keep it maximum a week. If you want to prepare a big batch all at once, you can freeze ice cubes of your aloe gel to eat or use on your hair later on (use the frozen aloe within max 6 months for maximum benefits).
