Meanwhile, many of P&G's biggest rivals, including Unilever, L'Oreal and Johnson & Johnson, have also cut their US adspend, according to TNS Media Intelligence.
The cuts come as marketers grapple with rising commodity costs, price hikes, rising own label sales and cost-cutting consumers.
P&G's cuts were focused on three brands - Olay, Pantene and Crest, which have traditionally been supported by the biggest budgets.
However, Olay and Pantene have seen sales slow and market shares fall.
