Reading hair in family photographs
How to use hair to help date a family photograph — and why hair alone can mislead.

Hair is one of the most useful clues for dating an undated photograph, and one of the easiest to over-read. This guide sets out what to look at and what to be careful of. A full interactive guide, “Read a family photograph”, is planned.
What to look at
- Silhouette: is the hair close to the head or wide? Is the volume at the crown, the sides or the back?
- Parting: centre, side or none; straight or zigzag.
- Length: as far as it can be judged, which is often not far when hair is pinned up.
- Texture and set: natural texture, waves, curls, a set, pressing or chemical straightening.
- Accessories: ribbons, bows, combs, pins, nets, snoods, scarves, hats.
- The photograph itself: the format, mount and studio name are often better guides to date than the hair.
Cautions
- People keep the styles of their youth. Evidence status: Interpretation Older sitters often wear styles that were fashionable decades earlier, so dating a group photograph by its oldest member’s hair can mislead by a generation.
- Children’s hair was chosen by adults, often specially for the photograph. It tells you about the occasion as well as the period.
- Studio portraits were staged. They show a chosen presentation at one moment, not everyday hair.
- Hats hide hair. In many periods, outdoor photographs show more hat than hair.
- Retouching could smooth, darken or reshape hair, especially in commercial portraits.
- Fashion spread unevenly by place, class, age and community. A “1920s” bob might appear in a 1930s photograph from a village or a school.
Record what you cannot tell
For every photograph, write down what it cannot establish: whether the style was everyday or special, who made it, how long it took, and what the sitter thought of it. That list is as important as the date.
