Details vary as to how the Doris Troy version came to be released on Atlantic Records. According to the book Billboard Book of One-Hit Wonders,James Brown saw Troy performing in a nightclub (under her then-stage name Doris Payne), and introduced her to Atlantic. According to a more recent and detailed story in Soulful Divas, Payne recorded a studio demo of the song and took it to Sue Records first, but their lack of response led her to offer it to Jerry Wexler at Atlantic, where the label released the demo unchanged. The personnel on this song included Horace Ott on piano, Snags Allen on guitar, Barney Richmond on bass and Bruno Carr on drums (although session musician Bernard Purdie has claimed that he was the actual drummer on the demo).
In 1963, Doris Troy scored her only hit on the U.S. Billboard Hot 100 chart with "Just One Look". The song spent 14 weeks on the Billboard Hot 100, peaking at No. 10, while reaching No. 3 on Billboard's Hot R&B Singles chart, No. 8 on New Zealand's "Lever Hit Parade", and No. 1 on Canada's CHUM Hit Parade. The single's release was the first time she started using "Doris Troy" as her stage name, though her pen name remained Doris Payne.
Doris Troy's version of the song was featured in a 1991 Pepsi commercial starring Cindy Crawford, which was reaired during Super Bowl XXXV in 2001. An updated version of the ad, still featuring Cindy Crawford and Troy's version of the song aired in 2002. In 2015, Troy's version of the song was featured in an ad for Aspartame Free Diet Pepsi. The song was also used in a series of commercials for Mazda beginning in 1979 and continuing into the early 1980s. The song is also featured in a scene in the movie Crazy, Stupid Love.
"Just One Look" became a hit in the United Kingdom via a cover version by the Hollies which reached No. 2 on the Record Retailer chart in April 1964. It became the 37th biggest hit of the year. Although not a major U.S. hit in its original release, the Hollies' "Just One Look" marked the first appearance of the Hollies on the Billboard Hot 100 at No. 98. A U.S. re-issue in 1967 reached No. 44 on the Billboard Hot 100.
