Unilever handed one agency three separate brands, TRESemme UK, Liquid I.V. and Simple Skincare UK, each needing its own year-round creator programme.
The problem is documented by somebody with nothing to gain from the agency winning the work.
How we know
The appointment on record covers creator programmes across all three brands, won on a competitive pitch, reported by both the UK and US editions of Campaign on the same day.
| Who says so | Campaign. Worth reading beside the three other Unilever rows on this sheet, which are three different agencies on other Unilever brands. Read it |
|---|---|
| A second source | Campaign ran the story in both its UK and US editions on the same day with the same three brands named. Buttermilk staff also posted the win publicly on LinkedIn, which confirms the agency side but is not independent. |
| What the agency was asked to do | Not published as a quoted brief. On record: Buttermilk was picked to lead creator programmes across three Unilever brands, TRESemme UK, Liquid I.V. and Simple Skincare UK. |
| How that happened | Campaign reports the appointment without describing a pitch, review or incumbent. Do not assume a process ran. |
| How long it took | Reported 16 December 2025. No pitch length, start date or term given. |
| Recorded as | Unilever (TRESemme UK, Liquid I.V., Simple Skincare UK) |
