European detergent specialist Henkel is set to buy the California-based hair care group Advanced Research Laboratories.

The deal, worth between $200m and $300m, comes just a week after Henkel said it would buy US consumer products group Dial for $2.9bn.

A company spokesman said: "The acquisition will take Henkel a significant step forward in the American hair cosmetics market."

ARL develops and markets hair care and styling products primarily in the USA, Canada and Mexico.
