Henkel has acquired Shiseido's Asia-Pacific professional hair business.

"The company is confident that integration of its professional business, whose brands are well established in Japan and Asia, with the Henkel Group, which possesses an extensive track record in the hair category in Europe and the United States, will provide the Business with global-level investment opportunities and business structure," said Shiseido in a statement.
