a closeup of Shelley from a 1977 Firm & Natural ad
Shelley appeared in many ads during her Supermodel days. One of them was for Firm & Natural hair spray. In the ad, women were urged to relax, because Firm & Natural hair spray held up even in the rain. It also came in a pump bottle, which wasn't just economical but environmentally friendly as well. Shelley was hands-down gorgeous in the ad.
