Sally Beauty Holdings, the $3.8B beauty supplies retailer and distributor, has put on its crisis face as it investigates a possible second data breach in a year.

sally beautyEdelman is advising the publicly traded, Denton, Tex.-based company. David Chamberlin, executive VP for Edelman in Dallas who heads its data security and privacy group, leads the SBH account.

Sally Beauty said May that it is investigating reports of "unusual activity" using payment cards at some of its stores and is working with law enforcement and its credit card processor in the probe. That revelation comes a year after the company initially mishandled a data breach that affected more than 25,000 customers.

"Until this investigation is completed, it is difficult to determine with certainty the scope or nature of any potential incident, but we will continue to work vigilantly to address any potential issues that may affect our customers," the company said in a statement.

Karen Fugate is VP of IR and strategic planning and Jan Roberts director of corporate comms. at SBH.
