who invented the straightening comb

The straightening comb doesn’t have a single, clear-cut inventor, but a few key names are usually highlighted in its history.

Quick Scoop

• A French hairdresser , François Marcel Grateau, is often credited with inventing an early hot/straightening comb in the 1870s in France to straighten hair with heated metal tools.

• In the United States , later patents refined tools specifically for straightening tightly curled or kinky hair, including a 1920 patent by Walter H. Sammons for a comb designed to straighten Black hair.

• Madam C. J. Walker did not invent the straightening comb, but she famously popularized hot combs and built a huge hair-care business around them, especially for Black women in the early 20th century.

Why there’s confusion

• Many people assume Madam C. J. Walker invented the straightening comb because of her massive influence and marketing around hot combs and hair-care systems.

• Hair-straightening tools evolved over time: early heated combs in Europe, then more specialized straightening comb patents in the U.S., and then widespread commercialization in Black hair care.

So if you’re answering “who invented the straightening comb,” the most accurate short answer is:
François Marcel Grateau is widely credited with creating an early hot/straightening comb in the 1870s, while later inventors like Walter H. Sammons and entrepreneurs like Madam C. J. Walker refined and popularized straightening combs, especially for Black hair.

TL;DR: There’s no single universally agreed “inventor,” but Grateau is usually cited as the earliest inventor of the hot/straightening comb, and Walker is the best-known figure who popularized it.
