So long, frizz! This drugstore serum has been a staple in the beauty aisle for years. Formulated with Argan oil and apricot, this silky serum calms unmanageable hair, banishes frizz, and adds in a healthy shine. It's potent formula is strong enough that it boasts a three-day frizz-free finish even in 97 percent humidity. We simply adore the scent of it and that a little goes a long way (one pump is more than enough!), so your $5 goes even further!
