It's been raining here in San Diego, so I'm thinking a lot about hair products that help eliminate frizz. I've tried dozens of hair serums to help get rid of frizz and boost shine. Funny enough, it was a drugstore brand, John Frieda, that I think is the winner. John Frieda Frizz-Ease Hair Serum is somewhat miraculous when it comes to fighting frizz. I put this all over my hair and then twist sections to bring out the wave, but's also good for straight hair. It comes in three different formulas: Light, Original, and Extra Strength. The Original formula works great for me, and at under $10, what do you have to lose?
