MAC and John Frieda stylists are influencing spring trends at New York Fashion Week as much as the designers that enlist their creative direction. At Zac Posen, both teams, along with Essie nail artists, went for sleek glamour.

For hair, this meant rich and shiny, or “rich girl hair” as Posen has been known to describe it. John Frieda consultant Harry Josh translated that to mean fresh colors — no roots and certainly no ombre that has been dominating street styles.

Josh and his team, also lead by consultant Luigi Murenu, used John Frieda Precision Foam Color (which can be found in drug stores for around $12!) to either bump up models’ natural color by a shade or bring it down a shade.

“Virgin hair doesn’t hold texture very well,” Josh said. So to achieve the “very high polish” effect Posen and Josh were looking for, models’ hair was freshly dyed.

Make-up artist Kabuki drew inspiration from a 1960s black and white photo of Lena Horne.

“The image captured her unique blend of strength and delicacy, echoing the play between structure and softness in the collection,” Kabuki wrote in an explanation of the look.

The result accentuated the models’ individual coloring with nude lips and natural cheek colors.

Nail colors were also based on the models’ skin tones. Four varieties were chosen based on the models: Glamour Purse, Brooch the Subject, Peach Perfect and Not just a Pretty Face.
