The song was recorded by Mikkel Storleer Eriksen, Miles Walker and Mike Anderson at Westlake Recording Studios in Los Angeles and Hide Out Studios in London, England.

Following the rap performed by Fetty Wap, Ally Brooke belts out the first verse: "Curtains like waves closing in all around us, dimming the lights just so that they don't blind us," backed by the percussion and guitar chords. Concerning his collaboration on "All in My Head (Flex)", Fetty Wap told Billboard that during the recording, his voice "wasn't as mature as it is now" and described it as "impossible" to perform on stage; "Like, I smoke way too much now. No more high-range. If you were actually to hear the first version to that song, I do not sound anything like that. It was way high up there. So when we changed everything I was like I don't think they going to like it because it felt like I took the energy from it. But they were like we love it, we rocking with it."

## Critical reception

Peter Meister of website Sputnikmusic described the song as "sassy and badass, Fetty Wap flexes his muscle with might within the funky, glowing synths crashing with the industrialized percussion which breaks free and explodes at all angles". Digital Spy's Lewis Corner described the song as having an "urban-pop undertone, which is brought to life with light reggae guitar plucks and crisp clicks". Christopher R. Weingarter of Rolling Stone felt that the Caribbean rhythms hinted at in Reflection's track "Them Girls Be Like" "burst forth" in "All In My Head (Flex)" and "Gonna Get Better".

Describing the song as "reggaeton-inflected" the Los Angeles Times Gerrick D. Kennedy believed that "All In My Head (Flex)", as well as another 7/27 track, "Not That Kinda Girl," "are the album's most infectious offerings". Spin's editor, Brian Josephs, complimented the song's reggae production and the group's sensual performance; however, he had a negative view of Fetty Wap's appearance commenting that the rapper "fails to come off here as much more than Default Guest Rapper". However, Spencer Kornhaber of The Atlantic felt that "All In My Head (Flex) brings in the most exuberant rapper of our times, Fetty Wap, to very catchy effect."

### Synopsis

The video begins with cinematic black bars expanding to reveal the scenery, which is set in a beach. Individual takes of the girls are shown momentarily as Dinah Jane sings the chorus. The camera shifts to Fetty Wap, who is sitting down in a chair with a guitar next to him. As he sings, the girls are seen dancing in the water, with Lauren Jauregui kicking the water as the video goes into a slow-motion take for less than a second. Several scenes include Normani alone in a rock cliff, a close-up of Dinah singing and a shot of the girls together near the water.
Ally Brooke then sings as she lays in the sand, moving sensually as an attractive man comes out of the water towards her. The camera fades to Lauren, who sings the bridge as she stands next to a background of rocks, as a take of another man is shown. The group is then scattered in different spots standing in a large rock formation, where shots of Dinah alone are spliced as she sings the chorus. Normani shares the chorus, as she sings on top of the rock cliff, shown earlier in the video. Camila Cabello seductively lays down and grabs her hair, in similarity to Ally. Several men approach the girls as they arrive in a convertible Jeep Wrangler. They greet and socialize with each other.
The scene changes to a beach-like bar equipped with cabanas and sand scattered through the floor. Each girl is dressed in beach draps and dance with a man as the scene interchanges with Fetty Wap's rap verse. A product placement for the app Friendable with the group's invitation is shown. The girls perform a dance routine in-sync as Normani and Dinah are shown individually dancing near a rock and on the sand. The video ends with each making a pose as the cinematic black bars close.
