Keeps your hair moisturized Mac styling tools never leave your hair thirsty or dry. On the contrary, they prevent loss of moisture during styling, by influencing it with the unique Satin Ions technology that penetrates your hair! The negatively charged ions stick to your positively charged hair, thereby reducing dry frizz and attracting moisturizing molecules from the air and directing them to the parts of the hair that need it most. Anti-static styling MAC's unique ion technology releases a stream rich in silky ions, enveloping each hair. This advanced technology acts as if it were a natural hair smoothener during styling, eliminating frizz, flyaways and static pressure, leaving your hair soft and shiny.
