Ways to tell them apart:

• Get my dander up is an idiomatic expression meaning to become angry or agitated.
• On the other hand, get my dandruff up is not a recognized idiomatic phrase; dandruff refers to flaking skin on the scalp.
• To remember, dander is related to emotions (anger), while dandruff is related to physical scalp condition.
• Think about dander as dust that can rise and irritate, metaphorically causing anger.
• Dandruff involves flakes, and no emotion; it's just a scalp issue.
