New Clothes, New Irritations: Washing Helps, But Some Chemicals Persist
New clothes can irritate skin due to substances like dyes (often azo dyes), fragrances, finishing agents, formaldehyde, and pesticides, especially in areas of friction. A cold rinse can remove much of these irritants, reducing exposure to dyes and fragrances, but some chemicals (e.g., flame retardants and antimicrobial finishes) may linger after multiple washes. For dry-clean-only items, steaming or airing out can help odors, and a barrier layer can be worn underneath; if a rash persists, consult a dermatologist. Most reactions are irritant dermatitis and short-lived, though allergic dermatitis can develop with repeated exposure. Washing may also affect collar stiffness and color vibrancy.
