The Water will Affect your Hair

One of the unique features of the geothermal water at Blue Lagoon is the high levels of silica. Silica is not harmful to hair. However, if you get your hair wet from the geothermal seawater, it can become stiff and difficult to manage.

To avoid this, either:

  • Keep your hair out of the water or use a swim cap (these are available to buy at reception)
  • Apply the complimentary conditioner provided in the shower area to your hair, and leave it in while you bathe


Once you have finished bathing, wash your hair thoroughly with silica purifying shampoo and use a lot of conditioner. You will probably need to repeat this process a few times to get all the silica out.

Blue Lagoon shampoo and conditioner are provided free of charge in the showers. You are welcome to bring your own if you want.
