A hot oil treatment in a sauna isn't a hack. It's actually one of the most scientifically sound ways to deep condition your hair and scalp, and it's something I've been recommending to clients for over 20 years.
Heat opens the hair cuticle. When the cuticle is open, oil-based treatments penetrate the cortex instead of just sitting on top of the strand. That's why a hot oil treatment done in the heat of a sauna will outperform the same treatment done at room temperature every single time.
Here's how to do it right.
Step 1: Choose the Right Oil
Not all oils belong in a sauna. Heavy, single-ingredient oils can become unstable at high temperatures or feel suffocating on the scalp under sustained heat. You want a formula with a blend of lightweight and restorative oils that work together, and that's been formulated to handle the heat.
Power Gloss was built for exactly this. Its seven clean ingredients, castor oil, jojoba oil, rosehip oil, sweet almond oil, rosemary, lavender, and apple cider vinegar, are heat-stable, salon-grade, and formulated specifically for sauna use. Every ingredient is doing a job.
Step 2: Apply Before You Enter
Apply 1 oz of Power Gloss to dry, clean, or dirty hair before you step into the sauna. Work it through from roots to ends. Pay special attention to the scalp, that's where the circulation benefits of sauna heat will amplify penetration the most.
You don't need to wrap your hair or use a shower cap. Just apply, go in, and let the environment work.

Step 3: Let the Sauna Do the Work
This is the best part. You're simply doing your sauna session, relaxing, sweating, and recovering. Meanwhile, the heat is opening your cuticles and driving the treatment deeper into every strand and follicle.
Power Gloss works in traditional saunas, steam rooms, and infrared saunas.
Step 4: Leave It On After You're Done
You don't have to rush to wash it out. Power Gloss is designed for a 2-24 hour leave-on window. Go home, run errands, relax. The treatment continues working even after the heat is gone.
The longer you leave it, the deeper the treatment.
Step 5: Wash Out Correctly
This step matters.
Shampoo 2-3 times, then condition as normal.
Oil-based treatments need multiple washes to remove fully. Skipping this step can leave buildup that weighs hair down and affects your scalp balance.
