Hot yoga, at temperatures of 85-105 degrees offers many benefits, from improved flexibility to detoxification, mindfulness, comradery, fitness, and improved scalp circulation. Its high heat and humidity can impact scalp health, health to the actual hair cuticle, and some hair texture and quality changes. Whether you have natural curls, color-treated strands, or fine hair, practicing in a heated room requires extra hair care.
1. Scalp Health & Circulation
Hot yoga increases blood circulation, which can benefit hair growth. The heat encourages vasodilation (blood vessel expansion), delivering more oxygen and nutrients to hair follicles. This can support stronger, healthier hair growth over time.
However, excessive heat may also lead to scalp dehydration or overproduction of oil, depending on your hair type.
✅ Good for: Boosting follicle health and stimulating hair growth. Self scalp massage can also improve local stimulation.
⚠️ Watch for: Dryness, fizziness, or excessive oiliness post-practice, extra precaution on pulling hair too tight during practice
2. Sweat & Hair Damage
Sweat is mostly water and salt, but prolonged exposure can affect hair strands.
- Salt buildup can make hair feel dry and brittle, especially if left to dry on the scalp.
- If sweat mixes with product buildup (hairspray, oils, dry shampoo), it may clog follicles and contribute to scalp irritation or dandruff.
Best Practices:
✔️ Rinse hair with cool water post-class to remove sweat buildup.
✔️ Use a mild, sulfate-free shampoo if washing daily.
✔️ Apply a lightweight leave-in conditioner or light protective oil before class to prevent dehydration.. Caution: think about sweating on your mat. Oils can drip.
3. Impact on Color-Treated Hair
If you color your hair, hot yoga can speed up fading and oxidation, especially for red and blonde shades.
- Heat opens hair cuticles, making it easier for color to wash out.
- UV exposure combined with hot yoga can cause brassiness in lighter shades.
How to Protect Color-Treated Hair:
✔️ Use a UV-protectant spray or leave-in conditioner before class. Some powders also help prevent some sweat build up
✔️ Wear a loose braid or bun to limit sweat exposure to strands.
✔️ Rinse with cool water post-class to seal hair cuticles.
4. Breakage & Frizz
High humidity in hot yoga can weaken hair bonds, leading to frizz and increased breakage.
- Curly and fine hair types are more prone to frizz and dryness in hot, humid conditions.
- Tying hair too tightly in a high ponytail or bun can cause tension-related breakage.
Best Practices:
✔️ Opt for loose braids or a low ponytail instead of tight buns.
✔️ Use a satin or silk scrunchie instead of an elastic band. And don’t forget to launder these regularly!
✔️ Apply a lightweight serum before class to lock in moisture.
5. Should You Wash Hair After Every Class?
Washing hair too frequently can strip natural oils, but skipping washes can lead to buildup.
Best approach:
- Rinse hair with water after class if you sweat heavily.
- Use a mild shampoo only when needed (every 2-3 classes for dry hair; more often for oily scalps).
- Dry shampoo can help absorb excess oil between washes.
Final Thoughts
Hot yoga stimulates scalp circulation, which may support hair growth, but it also exposes hair to sweat, salt, and humidity, leading to potential dryness, frizz, and color fading. By rinsing hair post-class, protecting it from heat, and using nourishing products, you can maintain healthy, vibrant hair while enjoying the benefits of hot yoga.
