In 1965 the band signed with producer Huey Meaux^[2] of Houston, who maintained a stable of record labels. "Treat Her Right" was recorded at Gold Star Studios (later known as SugarHill Recording Studios) in Houston. Issued on Don Robey's (Nov. 1, 1903 - June 16, 1975) Back Beat label, it reached No.2 on both the U.S. Pop and R&B charts in 1965,^[3] behind The Beatles' "Yesterday." "Treat Her Right", with its blazing horns and punchy rhythm,^[4] credited to Head and bass man Gene Kurtz,^[5] established Head as a prime exponent of blue-eyed soul.^[6] By 1995 "Treat Her Right" had been covered by as many as 20 nationally known recording artists including the Yardbirds/Led Zeppelin legend Jimmy Page, Bruce Springsteen, Jerry Lee Lewis, Bon Jovi, British blue-eyed soul vocalist Chris Farlowe (under the title "Treat Her Good") and both Mae West and Barbara Mandrell under the title of "Treat Him Right". Even Bob Dylan, Sammy Davis Jr. and Tom Jones^[7] covered it "live".

Roy Head and the Traits "Just a Little Bit" and the bluesy-rockabilly hybrid, "Apple Of My Eye" also cracked the Top 40 in 1965. However, those were only minor hits in the wake of "Treat Her Right", which is estimated to have sold over four million copies worldwide, and was a featured song, along with Wilson Pickett's "Mustang Sally" and Steve Cropper's "In the Midnight Hour", in the successful 1991 motion picture, The Commitments.^[8]

The song reached No.2 in the United States on both the Billboard pop and R&B charts.^[9] The Beatles' "Yesterday" kept "Treat Her Right" from the No.1 spot on the Billboard Hot 100. In Canada, it reached No.8.^[10] In the UK, No.30.
