Hans Schwarzkopf (1874, Danzig – 12 February 1921, Berlin) was a German chemist, entrepreneur, and inventor.
[1] Hans Schwarzkopf studied chemistry and in 1898 opened a "paint, drug and perfume shop" on Passauer Strasse in Berlin-Charlottenburg.
It cost 20 pfennigs per bag (for one treatment), was dissolved in water, and proved to be superior to all hair-washing soaps available at the time in terms of convenience.
The "shampoo with the black head" became the first branded hair cosmetic product in Germany.
Due to the success, Schwarzkopf gave up his drugstore in the same year and concentrated on production and marketing.
