@aggers.nicole: Refilled Cytokine Booster Pro really is that girl! I applied this to my scalp last night and again this morning and my hair has not looked greasy once. No mess to deal with, no heavy residue — just a cooling sensation, full absorption, and my scalp actually feels cleaner and less tense after two uses. Korean hair care is serious and this is proof. Patented cytokine complex, clinically tested, absorbs completely and you can use it every single day!
