What you need:
Aloe vera juice (or water**)
**Aloe vera is very good for your hair and will help decrease the drying effects of salt (and can aid in hair growth!). You can find it in most grocery stores in the health and supplement section.
How much you use of each product depends on the size of your bottle/how much you are making. For the size shown here, I filled the bottle about 3/4 of the way with aloe vera juice, used about 1 tablespoon of gel, and about 1 teaspoon of salt. I would err on the side of less salt, as when you add more it can make hair more dry and brittle.
Then, just shake it all up! Be sure to shake before each use, as product can settle on the bottom.
Thanks for viewing!
