By the looks of it, and Witherspoon's track record, we're betting this temporary change comes courtesy of a wig. "[My colourist] is meticulous about the balayage process and puts oil on the roots and tips so they don't break," Witherspoon recently told Allure . "But it takes three hours to have my highlights done, no joke. I go every seven or eight weeks." We don't see her messing with that routine, unless it's for bangs, which she told us she'll always have a "love-hate relationship with." Relatable.
