The Milstan Feather Flat Iron is a hair-straightening tool developed by Stan "Milstan" Nash for Milstan Thermal Products. The company advertises the iron as a replacement for the pressing comb introduced by Madam C. J. Walker in the early 1900s.
Milstan markets the Feather Flat Iron to African-American women as a tool for use in a hair-straightening process called “thermal relaxation.” This process uses a heated wand-like iron that avoids the damage to the hair and scalp associated with chemical straighteners and relaxers. The device has a thin design that enables the stylist to work extremely close to the scalp without causing discomfort or pain to the client. Using the Feather Flat Iron requires a skilled stylist since it does not run on electricity and the stylist must heat it in a stove.
