Ghost Exfoliating Scalp Nectar™ is a lightweight scalp serum that uses chemical exfoliation to gently remove buildup, dead skin, and excess oil for a clean scalp and healthier hair. Unlike physical scalp scrubs that require aggressive rubbing, this chemical scalp exfoliant lets AHAs and PHAs do all the work. Simply apply and let it sit, the treatment will break down buildup in 10 minutes while also adding hydration to avoid dryness that some scalp exfoliators cause.
