If you're lucky, summer hair has that sun-kissed, I-was-at-the-beach-for-thirty-thousand-hours, aren't-you-jealous-look. However, fun in the sun leaves your hair susceptible to all types of damage. Whether it's frizz or frighteningly dry locks, Sally Hershberger’s latest product, Hyper Hydration Super Argan Serum, is just what the doctor ordered—consider this must-have new product rehab for your summertime hair. The active ingredients include argan oil infused with antioxidant-rich amala oil (Indian gooseberry) and rice-bran oils, and is also the first serum of its kind to deliver color-protection with natural sunscreen. Slick it through wet or dry tresses to instantly deliver a smooth, defined, frizz-free style without added weight or residue. You might as well look your best while being in denial about the imminent end of our beloved summer.
