The review follows a number of purchases and brand expansions in recent years, most recently the purchase of Simple Health & Beauty in December 2009.
In the UK, Alberto-Culver's £15m account includes brands such as Tresemmé, Alberto VO5 and St Ives, and is handled by Havas creative agency Euro RSCG and Aegis media agency Carat.
The Alberto-Culver account in the US is understood to be worth a further $100m, with the majority spent on the Nexxus and Tresemmé hair care brands.
American incumbents include Wieden & Kennedy, Campbell-Mithun (part of Interpublic Group of Cos.) and Aegis' Carat.
Alberto-Culver bought Simple Health & Beauty from private equity firm Duke Street in £240m deal. Simple Health & Beauty spent £2m on media last year, with creative and media handled by Rainey Kelly Campbell Roalfe/Y&R and PHD respectively.
It is not clear at this stage whether the Simple account is included in the review.
When Alberto-Culver bought Simple, James Marino, president and chief executive, said the cosmetics giant intended to "continue to leverage Simple's brand strength to drive future growth" and called the purchase an "important step forward in executing our strategy of expanding and strengthening our portfolio".
