Detailed answer

Acne is primarily caused by a combination of factors, including excess oil production, bacteria, clogged pores, and inflammation. While dirty hair or hats can contribute to clogged pores and bacterial growth on the skin, they are not the sole cause of acne. Acne is mainly influenced by hormonal changes, genetics, and lifestyle factors. However, it is important to keep hair and hats clean to minimize any potential contribution to clogged pores and bacterial growth. Regular hair washing and hat cleaning can help maintain good overall skin hygiene and may reduce the risk of acne breakouts.
