Your shirt looks clean. So why might your skin feel itchy where a collar, cuff or waistband rests?

This video explores a laundry habit many people overlook, how clothing can interact with the skin, and why that interaction may become more noticeable with age. We look at detergent amount, rinse settings, fabric softener and the difference between everyday irritation and a possible contact allergy—without assuming that every itch has the same cause.

You'll also get practical changes to try on your next load. A brief mark after pressing fabric against your wrist cannot diagnose a skin condition or identify a particular ingredient. If a rash spreads, blisters, persists or keeps returning, speak with a dermatologist.

Tell us in the comments where you notice irritation most often: collar, cuffs, waistband, socks or somewhere else. Subscribe for more everyday body signals explained clearly.
