Your Hairbrush May Be Dirtier Than a Toilet Seat, Experts Warn

If you do not clean your hairbrush regularly, it can become dirtier than a toilet seat. Why Hairbrushes Accumulate Bacteria "If you do not wash your hairbrush at least once a week, a huge number of bacteria, sebum residue, dust, and dead skin particles accumulate on its bristles. According to research, in such a short time up to a million microorganisms can form on the surface of a hairbrush, including bacteria that cause inflammation and acne," trichologist and dermatovenereologist Yulia Markova said in an interview with Life.ru. Markova explained that sebum, produced by the sebaceous glands, serves as a nutrient medium for bacteria. When it mixes with dust and dead skin cells, it forms clumps that clog pores. "Indeed, a hairbrush can become dirtier than a toilet seat — this is a fair statement,” she noted.
