Hair gets walked through labeled stages (Dirty, Washed, Detangled, Air dried, Styled) and ends on a hair flip, all to one shared sound.
Shot from behind with a small label per stage, her hair goes from dirty to a long wavy styled finish, and commenters joke that the dirty and styled stages look the same.
Very long hair gets steamed and brushed out through each label, then ends on heatless curls, which is what commenters had been waiting for from the first frame.
A guy runs the same labeled stages, opening on a slick back before the curls come out, which shows the format works on short hair too.
