Hair can also be at risk in everyday work
In many professions, there are regulations on what workers must wear at work. Mandatory headgear, the uncleanliness of the environment, can all affect the health of their hair.
How often should I wash my hair?
The eternal question is: how many times a week should you wash your hair?
People used to wash their hair every two weeks, although back then there wasn't as much dust and smog in the air, so frequent hair washing wasn't necessary. Now, however, it would be impossible to go a week without cleaning your hair.
