cyclomethicone and dimethicone. It's not hard to make one of these at home. The big difference between the serum and the spray - the serum tends to use the higher c.s. dimethicone (thicker), whereas the spray tends to use the lower c.s. dimethicone (thinner).
BASIC ANTI-FRIZZ SPRAY
10% dimethicone (can be 350 cs to 1000 cs)
Get a spray bottle and put it on a scale. Measure your cyclomethicone and dimethicone. Put on cap. Shake well. Enjoy.
I like to use this after my leave in conditioner but before brushing my hair.
BASIC ANTI-FRIZZ SERUM
30% dimethicone (preferably 1000 cs).
Get a bottle with a dropper and put it on your scale. Follow the directions as above. Enjoy.
If you want to add some oils to this kind of product, add up to 10% oil of choice in place of 10% of the cyclomethicone. You can add some of the silicone replacements in these ingredients, but they will make your hair oilier than if you are using silicones.
