Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
Hair being bleached with hydrogen peroxide is a chemical change, not a chemical property. Chemical properties describe how a substance reacts with other substances to form new substances, while a chemical change involves the actual rearrangement of atoms and molecules in a substance.

Physical.
