Put a 4 ounce/125 ml spray bottle on your scale and measure out 90 grams of cyclomethicone, 10 grams of dimethicone. Put sprayer into bottle. Spray onto your hair after washing and leave in conditioning, but make sure you don't coat the walls and counters of your bathroom with it! (I spray it into my hand and then smooth over my hair because I don't want a sticky bathroom!)
Yep, that's it. You can choose different types of dimethicone. I find the 1000 c.s. keeps the frizzies down more than the 350 c.s. dimethicone, but either is good.
As for fragrances - do you remember the discussion about polar and non-polar ingredients? This is a huge factor with silicones. Silicones are polar, thus any fragrance oils you add to this mixture MUST be polar. If they are not, they will create a little tornado in the bottom of the bottle (it's actually kind of cool to watch), and they will turn into little weird flakes. So add fragrance oil at 1% if you wish, but make sure your fragrance oil is polar!
That was simple, eh? And it didn't cost $25 for the bottle, either!
WAIT! There's no preservative there! I know, I'm always going on and on about how you must use a preservative, then I give you a recipe without a preservative. You don't need a preservative in something that doesn't contain water. These are called "anhydrous" (without water) products, and this is one of those. The anti-frizz spray contains only silicones, which don't need a preservative.
Nice segue, eh? Tomorrow we'll be starting on the anhydrous products using oils. So join me in the next two weeks for information on making your own whipped butters, bath melts, bath oils, apres bath lotions and sprays, fragrance sprays, and more!
