Ways to tell them apart:

• Get my dander up uses dander, which refers to anger or irritation, and not something physical on your scalp.
• Dander is related to a metaphorical state of being upset, whereas dandruff is a physical condition concerning skin flakes.
• Get my dandruff up is incorrect because dandruff is not something that can be raised or increased as dander refers to emotional state.
