The agency will develop campaigns for the Right Guard, Schwarzkopf Live Colour Supersoft, Gliss and got2b styling brands.
The appointment comes ahead of the UK launch of a new Schwarzkopf product next year. The agency will create a campaign to support the launch.
Henkel has previously used agencies from its global ad roster to work on its UK campaigns.
MCBD was appointed without a pitch.
In September, Schwarzkopf Live Colour teamed up with 4Music to take over all the ad breaks during five hours of peak programming time, in a cross-platform, brand boosting campaign to target young female consumers.
Previously Schwarzkopf signed up celebrity Lisa Snowdon as the face of the brand.
