Detailed answer

Blackheads are caused by the accumulation of sebum, dead skin cells, and bacteria within the pores of the skin. Allergic reactions to laundry detergent typically manifest as skin irritation, itching, redness, or rash. They are not directly related to the development of blackheads. However, using certain comedogenic (pore-clogging) ingredients in detergents or fabric softeners can potentially worsen existing blackheads or impede their removal. It is important to choose non-comedogenic products and maintain a proper skincare routine to prevent and treat blackheads effectively.
