Blue Lagoon and your hair: Tips for the best care

The Blue Lagoon’s mineral-rich geothermal seawater won’t damage your hair, but it can leave it feeling temporarily dry or stiff, much like a swim in the ocean. Learn how different hair types are affected and get simple tips to protect your hair, so you can fully enjoy your visit.

Is the Blue Lagoon harmful to your hair?

No, the Blue Lagoon’s renowned geothermal seawater is not harmful to your hair.

The water contains high concentrations of minerals, such as sulfur, silica, and magnesium. While these are great for your skin, they can leave your hair feeling temporarily dry and matted. To minimize these potential effects, we recommend that you avoid immersing or soaking your hair in the water for too long and that you rinse your hair with fresh water after exiting the lagoon. However, if your hair is immersed for more than a few minutes, have no fear: it will return to normal after 2-3 washes. In essence, the effects of geothermal seawater on your hair are no different from the effects of ocean water, with its high salinity.

How does Blue Lagoon water affect different hair types?

The effect of the Blue Lagoon’s geothermal seawater depends on your hair type. Those with naturally dry hair should be aware of the drying effect when enjoying the lagoon, as their hair can feel even drier than normal. Those with naturally oily hair, on the other hand, may find that the geothermal seawater helps balance the oil production in their scalp. For those with flat hair, the water can actually add texture and volume.
