Spend a year in Los Angeles and you’re bound to emerge more beautiful than ever: tanned by the sun, toned by the surf and smiling from ear to ear. Most likely, however, you won’t be able to say the same for your hair. With its harsh sun, dry air, smog and hard water, Southern California is the mortal enemy of luscious locks. Tom Lux, co-founder of Formula Cosmetics, noticed a change in his own hair after he moved to Los Angeles from the East Coast: “All of a sudden, my hair got brittle. In the shower, it felt soapy, like the suds weren’t being washed off.” Motivated by similar complaints from his friends, Tom created Formula L.A., a sulfate-free shampoo and conditioner duo designed specifically to combat L.A.’s environment with sunscreen, moisturizers, anti-oxidants and a special ingredient that removes mineral build-up from your strands, all packaged in recyclable aluminum bottles, so you can continue your love affair with SoCal without cheating on your tresses.
