For many, the sauna is a sacred space of relaxation and renewal. But while the heat, steam, and rituals do wonders for body and mind, they can be demanding on your hair. High temperatures and repeated heat exposure can dry out the hair shaft, make it brittle, and strip away natural moisture. The good news? With the right care and products, your hair can thrive in sauna just as much as you do.
In this article, we’ll share the best tips on how to protect your hair in sauna and introduce the sauna/ing Hair Oil, your natural ally for sauna hair protection.
Why hair needs protection in sauna
Inside the sauna, temperatures range from 70–100°C. This sudden heat causes the hair’s cuticle (the protective outer layer) to open up, making strands more vulnerable to moisture loss and breakage. If you repeat this cycle often without protection, hair can become dry, frizzy, or weak.
Moisture is especially important for colored, chemically treated, or naturally dry hair, as they are more sensitive to sauna heat.
Simple steps for protecting your hair in sauna
-
Rinse before you enter
Lightly wetting your hair before sauna prevents it from absorbing too much dry heat. -
Braid or tie it up
Keeping hair in a loose braid or bun reduces tangling and mechanical stress. -
Cover your hair
A linen sauna hat or towel protects hair from direct heat. -
Use a natural sauna hair oil
This is the most effective way to protect and nourish your hair while you enjoy the sauna.
sauna/ing Hair Oil, the spirit of Ruissalo
Our sauna hair oil was inspired by Ruissalo, an island of ancient oak forests and rocky shores outside Turku, where the sea meets the sauna. Much of our research and development has taken place at Ruissalo Sauna, during cold-water swims in the Archipelago Sea. From this setting of pure nature, our Sauna Hair Oil was born.
Key benefits in sauna:
