If you want your wedding hairstyle to hold even in high humidity, this homemade dry shampoo is my secret weapon. Okay okay, before you roll your eyes about the fact that dry shampoo is yesterday's news, read on. This isn't just any dry shampoo, this is totally my favorite that I stumbled on, and it has only one ingredient.

Wait for it...

The one ingredient is diatomaceous earth. Yep, say that three times fast! Di-A-To-Ma-ceous earth.

Diatomaceous earth is defined as a soft, powdery, porous sedimentary deposit formed from the fossil remains of diatoms. There are tons of uses for it, but we're going to use it to absorb oil with low buildup.

Using diatomaceous earth as a dry shampoo was actually a total accident! I would love to say that I came up with a hypothesis based on its porosity levels and molecular structure, but the truth is just not so. About three years ago I broke my ankle. I had to figure out how to make my hair look presentable after laying in bed all day recovering. I couldn't drive, even to the drugstore.

Must make dry shampoo... must make dry shampoo...that was my new mantra. I tried all the Pinterest advice: from cornstarch to arrowroot powder, rice flour to cocoa powder. They all did about the same thing, absorbed oil (which was good) but it just didn't give me the result I wanted.

I am not saying that store-bought products are bad, but if I can make my own and know exactly what's in it, that's a huge bonus for me. I was about to give in and stick with the rice flour because it did the trick of making my hair look fresh, until one day when I was applying diatomaceous earth to our dog's coat to keep pests away (yep, it's also a powerful organic anti-pest anti-parasite treatment), and I realized his coat had that feeling I was after - almost a tacky feeling, but still dry and not heavy at all. I went for it and tried a little on my part line. Then more and more until my hair had essentially doubled in size and was feeling so ready for a good curl.

Since then, I've used it any time I really want my curls to last (like my wedding day!). Simply apply with a large makeup brush from roots to ends on dirty or clean hair, style as you like, add a little more in hands and crunch into cooled curls if needed, and you're ready.

You can snag some food grade diatomaceous earth on Amazon, Etsy, health food stores, or pet supply stores.
