Jonathan Vautrey from Wiwibloggs said, "A week later than originally planned, Sweden's Benjamin Ingrosso has now released his new single 'Shampoo'. The Eurovision 2018 star gives us a glimpse of the personal hygiene routine that he goes through before his lover comes over: “I have showered an hour or more / Need some towels to wipe up this floor … Now put on some shampoo”. Sonically, the track is percussion-driven and has a wonderful casual-summer vibe to it. The last third of the song is mainly an instrument breakdown, with the trumpets adding an extra Latin-jazz flavour to the track."[2]
