For Kieran Dodds, photographing people with red hair has become a passion that began in Edinburgh in 2013. He launched a series exploring Scottish identity and soon found himself traveling to Perm in Russia and Treasure Beach in Jamaica, gathering portraits of a wide variety of red‑haired individuals.

His 2020 book "Gingers Spanned the World" highlighted global diversity, but the author noticed a notable absence: American subjects. He reached out to the United States, and an avalanche of contacts followed, inspiring a multi‑state journey.

Along the coast of Alabama he met individuals whose heritage blends Native American, European and African roots. One story revealed a Cherokee girl named Lakia who never had known any European ancestry yet boasted a deep ruby hue in her hair, challenging assumption about the origin of the pigment.

Another portrait presented Joshua Elliot, son of a Muscogee (Creek) Nation mother and a father with German, English and Swedish descent, whose heritage mirrored the book’s central theme: a golden thread that connects disparate cultures. Dodds emphasized that in the United States, many people consciously recognize where their ancestry comes from, creating a tapestry of migration and identity.

The author estimates that roughly 4 % of Americans carry the ginger gene, suggesting a population comparable in size to a major city that would shine when seen from space. While the number is far from widespread, it is profoundly significant as it illustrates the country's layered makeup.

Dodds notes that the book is not merely a catalog of hair; it is a road trip across America to uncover stories of heritage, community and belonging. He approaches the subject with an appreciation that the term "ginger" can be used positively, celebrating instead the unique aesthetic of red hair as a symbol of shared humanity.

With the recent men's football World Cup drawing global attention to the U.S., the author is hopeful that part of America’s diversity can be appreciated. He calls it a renewed patriotic sense for his journey, inviting readers to look beyond surface differences and recognise the golden thread that unites people across the nation.
