6. Straight and great. If you haven’t already heard about Aveda’s new Smooth Infusion Naturally Straight styling product, OMG. Dab a little onto hair, comb through, and blowdry. Little by little (the more you often you use it), your hair’s curl will loosen. Should you decide to stop using the product, it only takes a few shampoos to return to your regular spirals or waves. As per Aveda’s usual M.O., it’s full of natural goodness and plant extracts to get the job done vs a ton of weird chemicals. A $26 bottle is enough product to last my long, thick, wavy hair all till September, so it’s an extra great value, too. Available here.
