Breck was a shampoo that featured different blends for dry, oily or normal hair. They used to have ads in the 30’s through 80’s featuring young ladies with pretty hair, and they called them “Breck Girls.” Some of the most famous models were Breck Girls, including Kim Basinger, Jacklyn Smith, Cheryl Tiegs, Brooke Shields, Christie Brinkley and others. The person mentioning this was trying to make a compliment of the highest order. Like saying: “your mom is a unique beauty.”
