TRESemmé is an American brand of hair care products first manufactured in 1947 by the Godefroy Manufacturing Company in Manhattan, New York City, New York, United States. It was named after the renowned hair care expert Edna L. Emme. The brand name is a phonetic respelling of "beloved" (French: très-aimé) that includes the surname of its namesake.
The TRESemmé product line was initially marketed only to beauty salons. The TRESemmé brand was purchased by Alberto-Culver in 1968 and then acquired by Unilever in 2010.
