With fans fascinated by their hair, which reached a collective length of over , Fletcher Sutherland went on to create a
patent medicine, "The Seven Sutherland Sisters Hair Grower", which was mostly
witch hazel and
bay rum, along with traces of
hydrochloric acid, salt, and magnesium. The tonic quickly became a best seller, and the line of Sutherland Sisters hair products expanded to include a scalp cleanser, brushes and combs, and "Hair Colorators." In addition to wholesaling their products to retail stores, they also made public appearances at retail outlets, and maintained several outlets of their own – "parlors" where customers could consult with a salesperson and make purchases—including one in
New York City. The Sutherlands resided in a mansion they built in
Warrens Corners, New York, which burned down in 1938. Even though hairstyles changed over time, and the short hair of the
flappers became fashionable in the 1920s, the Seven Sutherland Sisters hair care products were successful for years after their singing act ended in the mid-1910s; print ads for them appeared in newspapers until the mid-1920s. Published accounts indicate that the sisters did not save or invest wisely, and some of them later became destitute. When the last living sister, Grace, died in 1946 at age 92, she was buried in an unmarked grave. ==References==
