Hair ... and other minor things

Original:  Ad for Mulsified Cocoanut Oil Shampoo, Ladies' Home Journal, April, 1919

Tom was Rapunzled! 

This is another one of those ad pics I don't understand. Why did the MCOS company run it? The woman isn't smiling, looking happy about her hair like she would be if the artist had drawn her to sell the shampoo; she just has a puzzled "What happened?" look on her face. Of course that is what I picked up on for this cover.
