You love your sauna sessions. The heat, the sweat, the reset, it's everything. But every time you step out and run your fingers through your hair, you wonder: Is this doing damage? It's a fair question, and after 20 years and over 100,000 hours of professional work with hair and scalp, I can give you a real answer.
Â
What Sauna Heat Actually Does to Hair
Heat, whether from a sauna, infrared room, or steam room, temporarily lifts the hair cuticle. That's not inherently bad. In fact, it's the same principle stylists use when deep conditioning under a hooded dryer. The issue isn't the heat itself. It's what happens when hair cuticles are open, and nothing is protecting them.
When the cuticle opens in a hot, dry sauna environment without a protective treatment, moisture escapes rapidly. Hair becomes more porous, more brittle, and more prone to breakage over time. Add sweat. which is slightly acidic and can affect the scalp's pH balance, and you have a recipe for dullness, dryness, and scalp irritation.
The sauna isn't your enemy. But going in unprotected is.
Â
The Right Way to Sauna Without Sacrificing Your Hair
This is where most people get it wrong: they skip the prep. A pre-sauna hair and scalp oil isn't a luxury; it's protection.
When you coat hair and scalp with a nourishing oil treatment before entering the sauna, you're essentially doing two things at once:
-
Creating a moisture barrier that prevents the cuticle from losing hydration
-
Using the heat to drive the treatment deeper into the hair shaft, turning your sauna session into a professional-level deep treatment
That's exactly what Power Gloss was formulated to do. Apply 1 oz to dry, clean, or dirty hair before your session. Work it through your hair and scalp. Let the sauna do the rest.

Leave It On, Then Wash It Out Properly

Shampoo 2–3 times, then condition as normal.
