Erica LambergRegular sessions often bring visible improvements in general well-being, skin condition and muscle recovery. However, while the mind and body are benefiting, hair – especially that which has been colored – can start to show signs of exhaustion.
Saunas, quite expectedly, are not a particularly favorable environment for hair. We are talking about areas where the temperature ranges between 65 and 87 degrees, and after leaving the sauna, the hair often seems much drier, coarser and more prone to frizz than usual. This is precisely why the question arises whether this favorite wellness ritual, despite its many benefits, can have a long-term negative impact on hair quality.
One of the basic rules of hair care is to avoid heat whenever possible. Although staying in a sauna is not the same as directly exposing your hair to a curling iron or flat iron at extremely high temperatures, continued exposure to heat can produce similar effects.
How the heat from the sauna affects the health of the hair
Exposure to high temperature, even when the heat is not directed directly at the hair, causes the hair cuticle to lift. This allows moisture and natural oils to evaporate more quickly, causing the hair to lose softness and smoothness and begin to look dry – even when it is not seriously dehydrated on a structural level.
During sweating in the sauna, the body loses moisture, and the same happens with the hair. After that, it often needs additional care to restore its usual shine and suppleness. The good news is that there are simple steps that can significantly mitigate these effects.
How to prevent hair drying in the sauna
The woolen or felt cap that you often see in the sauna is not a fad. It is a so-called banya cap , an accessory with a very clear function: it helps regulate heat exposure and creates a microclimate around the head. In this way, it slows down the penetration of heat, protecting the hair and strands from sudden drying, especially during longer or more intense stays in the sauna.
People with thin, curly or chemically treated hair should be extra careful, as these types of hair naturally lose moisture more quickly, and heat only speeds up the process. In such cases, it is recommended to wet the hair before entering the sauna, since wet hair retains moisture more effectively than completely dry hair.
An additional type of protection involves applying a conditioner, mask or light oil before the session itself. These products create a protective barrier against heat and help preserve hydration. Lightweight formulas, like Jupiter Deep Moisturizing Conditioner, are even suitable for applying directly to the roots, without feeling heavy or greasy at the roots.
At the end of the sauna stay, it is recommended to re-apply a nourishing conditioner or mask, such as the Milbon Moisture Replenishing Treatment, to further nourish the hair. If more intensive regeneration is needed, a good option is a deep mask, such as Gisou Honey Gloss Ceramide Therapy Hair Mask, along with wearing a silk cap or turban at night, such as the Slip Pure Silk Turban, to restore softness and elasticity.
The good news is that you don’t have to give up the sauna for healthy hair. However, without adequate rehydration and protection, frequent trips to the sauna can lead to hair breakage and stiffness. Heat alone does not damage the hair at the molecular level – it primarily removes moisture. With a little attention and consistent care, it is possible to preserve the shine, softness and vitality of the hair, without renouncing your favorite relaxation ritual.
