Just launched in April 2018, Frédéric Fekkai's The Uplifting One Volumizing Shampoo ($30) and Conditioner ($30) are great for Summer for a few reasons. For starters, the shampoo contains a UV filter that protects your hair from sun damage. Second, both are formulated with south sea blue seaweed extract, which pumps up the volume for Ariel-level body.
