Why swap

Shampoo and conditioner bottles are among the most common bathroom plastics. Bars remove the bottle, and one bar typically lasts as long as two or three bottles.

What to look for

  • Bars in card or paper packaging
  • A tin or dish that lets the bar dry between washes

Watch out for

  • Some bars take time to suit hard water — a vinegar rinse helps
  • Refill pouches are still plastic
