Q&A for How to Make Homemade Shampoo

Any homemade shampoo that doesn't have an added preservative should be refrigerated between uses and you can probably expect a shelf life of 4-6 weeks with proper care. But, you should carefully monitor it for any changes (like color or odor) that may indicate a bacterial or mold growth.

Baking soda will clean your hair and scalp (removes oil) and because it is a bit gritty, it helps loosen any build up of hair products.

When you apply vitamin E to your scalp, it helps reduce inflammation and repair damage to the follicles, and healthy follicles encourage hair growth. If you do want to apply essential oils for some scalp benefits, hair growth, fragrance, and calming effects, add oil to hair products.

I have added aloe vera gel to my shampoo before and it seems to have worked out okay. I don't know if adding pure avocado would be a good idea though because you'd need to find a way to preserve it. An alternative is using smashed avocado with other ingredients like yogurt as a hair mask. You could also add avocado oil instead of raw avocado to your shampoo.
