There's no ban on aerosols in carry-ons, they just have the same (silly) restrictions as liquids.
"3-1-1 for carry-ons. Liquids, gels, aerosols, creams and pastes must be 3.4 ounces (100ml) or less per container; must be in 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. The bag limits the total liquid volume each traveler can bring."
