Detailed answer

Blackheads, which are small clogged pores, are not contagious and cannot be transmitted from one person to another through skin-to-skin contact. They are formed due to excess oil, dead skin cells, and bacteria accumulating in the pores. While blackheads may appear similar to certain contagious skin conditions like acne or folliculitis, they are not caused by an infection and do not spread between individuals. Blackheads are typically a result of individual skin factors such as genetics, hormonal changes, or improper skincare routines. To treat and prevent blackheads, it is important to maintain a regular skincare routine that includes cleansing, exfoliating, and keeping the pores clear of excess oil and debris.
