I will not be making my own moisturizer unless I get desperate, but I have been asking myself lately, how? To be moisturizing I would need water (preferably distilled), some kind of moisturizing oil(s) or butter(s), and an oil and water preservative. Normally when mixing oils you do not need to add a preservative, but when mixing oil and water, the product can go bad pretty fast.
Simple rule: oil + water=bacteria
As I have spoken of before, my favorite butters are Hemp Seed, Mango, Macademia Nut, Olive, and Avocado Butter. Mango butter makes a great product base because it is so very solid and the other three are very moisturizing and nourishing butters that penetrate the hair shaft.
Then I would add a couple of oils for more nourishment and to whip the butter into a more pliable state. My favorite oils are avocado, wheat germ (stinky), coconut (Vatika), and castor oils.
You could add essential oils for stimulation of hair growth and for a pleasing scent like rosemary essential oil, chamomile essential oil, or orange essential oil. Adding aloe vera gel or juice might be a good option to promote strong hair that sheds less.
These help the oil and water mix and not separate once the mix has set. Without this step, the chances are good that the mixture will not mix and you will just have a creamy mess on your hands.
As stated earlier, you must use a preservative when mixing oil and water. Personally I like grapefruit seed extract, liquid germall plus, and vitamin e (Wheat Germ Oil contains significant amounts of vitamin e). You can google search for the correct proportions of preservative to product.
When making natural products it is best to make as much as needed at the time because the shelf life of natural products is not very long. The best part about this is that most products can be bought locally at whole foods, local health food stores, African markets, and so many more local places. So if you are a mixtress, this is a great recipe for hair moisturizing success.
