Here is a charming hairstyle and photo straight from the 1950's showing a ten year old girl holding a baby.
This lovely young lady has her hair pulled back into a ponytail and her bangs are cut very short and straight across the forehead. They are deep set with a defined part in the shape of a V. They are combed straight and forward. This was very typical for this time period for girls. Her ponytail is probably placed in the middle at the back of the head. Her hair color is dark brown.
