Hair is a vital part of many people’s identity and learning how to care for it can take years of trial and error. And when it comes to figuring out how often to wash them, many of us are left in doubt. How often should we do this? We asked Dr. Cristiana Colonna, dermatologist at the Pediatric Dermatology Department of the IRCCS Ca ‘Granda Foundation – Ospedale Maggiore Policlinico di Milano.

Let’s start from the beginning. Our hair becomes greasy due to the accumulation of sebum: a fat produced by the sebaceous glands spread all over the skin and particularly concentrated on the scalp. The accumulation of sebum on the hair favors the adhesion of dust and dirt on them and the shampoo works by removing sebum and dirt accumulated on the scalp and on the hair shaft. How often to use the shampoo also depends on the lifestyle – explains Dr. Colonna -: for those who live in the city it is advisable to wash their hair often, for example every other day to remove dust and smog.
