Pollution and Hair: How Often to Wash and How to Protect It

Pollution and Hair: How Often to Wash and How to Protect It

Dust and smoke cling to oily scalps and hair. If you live in a polluted city, your hair wash habit may need to change.

How often to wash

Two to three times a week works for most people. If you commute through dusty roads, wash when the scalp feels dirty or itchy, with a mild shampoo.

Protect on the go

  • Tie hair back or cover with a scarf.
  • Avoid leaving heavy oil on while commuting. It traps dust.

When you get home

Weekly care

Oil and wash once a week. See our oiling guide.

Dust on the scalp

Dust and smoke mix with scalp oil and can make the scalp itchy and the hair dull. If you commute daily, you may need a slightly more frequent wash than someone who stays indoors.

  • Wash when the scalp feels dirty or itchy.
  • Use a mild shampoo.
  • Avoid heavy oil before commuting.
  • Cover hair with a scarf.

Weekly care

Do one oil massage and wash a week, and give your scalp a rest from styling products.
