The grunge era may be over, but this weekend, Jessica Alba pulled out her best punk-inspired hair. Jessica already has the two-toned hair color that was so popular in the '90s (and has reemerged in the ombré trend). But achieving her carefree waves is easy if not quite effortless. Since this style is all about being messy, start with second-day hair. Dampen strands with water or leave-in conditioner. Then create two to three French braids (don't bother with perfection). Allow the hair time to dry or do the braids right before bed. In the morning, press a warm flat iron to the braids to lock in the waves. After unraveling, spritz hair with dry shampoo to get volume and a more matte look. Finally, scrunch and fluff with fingers. Jessica updated her grungy hairstyle with a pop of orange lip color — the antithesis of the moody smoky eye.
