How to make aloe vera shampoo
Obtain organic aloe vera gel from a health or natural medicine shop.
Commercially available aloe vera gel is sold in bottles and they come in varying degrees of purity. Many of these commercial products contain additives and chemicals.
Since you'll be using this shampoo directly on your hair and scalp, it's best to get the purest aloe vera gel you can find. Check the label and ingredients before you buy a product.
