Heatwave Hair Health: Protecting Your Scalp from Extreme Temperatures

Scorching Heatwave Grips south Korea, Temperatures Soar to 37°C

Seoul, South Korea – South Korea is currently experiencing an intense heatwave, with nationwide heatwave advisories in effect. Temperatures are forecast to reach a sweltering 37 degrees Celsius in many areas today, marking a continuation of the oppressive hot weather.

The Korea Meteorological Administration has confirmed the widespread “heatwave special report,” predicting daytime highs around 35 degrees Celsius, emphasizing the extreme heat across the country.

While most regions will enjoy clear skies, Jeju island is expected to be cloudy, with patchy clouds also anticipated in the Gyeongnam area. Jeju Island may experiance light rain, ranging from 5 to 30mm, during the early morning hours.

Coastal areas, including the west coast, southern coast, and Jeju Island, should be aware of rising water levels that could lead to localized flooding and sewage backflow.Forecasters indicate that morning temperatures will remain slightly above average, with daytime temperatures expected to be 2 to 5 degrees Celsius higher than usual.Minimum morning temperatures are projected to range from 22 to 28 degrees Celsius, while daytime highs will reach between 32 and 37 degrees Celsius. The persistent heat raises the likelihood of “tropical nights,” where overnight temperatures fail to dip below 25 degrees Celsius,offering little respite from the warmth.

Here’s a breakdown of average morning and projected afternoon temperatures in major cities:

Seoul: 28°C (morning) / 37°C (afternoon)
Incheon: 26°C (morning) / 34°C (afternoon)
Suwon: 26°C (morning) / 36°C (afternoon)
Chuncheon: 24°C (morning) / 35°C (afternoon)
Gangneung: 26°C (morning) / 35°C (afternoon)
Cheongju: 26°C (morning) / 36°C (afternoon)
Daejeon: 25°C (morning) / 37°C (afternoon)
Jeonju: 25°C (morning) / 37°C (afternoon)
Gwangju: 26°C (morning) / 36°C (afternoon)
Daegu: 25°C (morning) / 35°C (afternoon)
Busan: 26°C (morning) / 33°C (afternoon)
Jeju: 27°C (morning) / 32°C (afternoon)

The concentration of fine dust is expected to remain at a “good” level throughout the day.

Beat the Heat: Protecting Your Scalp from the Summer Sun

While enjoying the summer season, it’s crucial to remember that the extreme heat and humidity also take a toll on our skin, including our scalp. The relentless sun and elevated temperatures can negatively impact scalp health, perhaps leading to increased hair shedding and even hair loss.To combat the effects of the heatwave on your scalp, minimizing direct ultraviolet (UV) ray exposure is paramount. Just as you protect your skin with sunscreen, wearing a hat when venturing outdoors is a simple yet effective measure. Opt for loose-fitting, breathable hats that allow for good air circulation, as tightly fitted headwear can impede blood flow to the scalp. Additionally, seeking shade whenever possible can further reduce UV exposure.

Be mindful of air conditioning usage. While essential for comfort, direct blasts of cool air can strip the scalp of its natural moisture, leading to dryness and increased sensitivity. A significant difference between indoor and outdoor temperatures can also exacerbate scalp irritation. For optimal comfort and to prevent dryness, it’s recommended to set air conditioners to a temperature between 25-28°C and avoid prolonged exposure to direct, strong airflow.

What specific protein changes occur in hair due to heat exposure, and how does this contribute to increased fragility?

understanding the Impact of Heat on Your Hair & Scalp

Heatwaves, increasingly frequent and intense due to climate change (as highlighted by the World Health institution [https://www.who.int/india/heat-waves]), aren’t just a threat to our overall health; they significantly impact our hair and scalp. Prolonged exposure to high temperatures can led to a range of issues, from simple dryness to more serious scalp burns and hair damage. Understanding how heat affects your hair is the first step to protecting it.

Increased scalp Temperature: A hot scalp encourages increased sebum production, potentially leading to clogged follicles and breakouts.

Dehydration: Both hair strands and the scalp can become dehydrated, resulting in brittle, fragile hair prone to breakage.

UV Radiation: Intense sunlight accompanying heatwaves delivers damaging UV rays, stripping hair of its natural oils and fading color.

Protein Loss: Heat can denature the proteins in your hair, weakening the hair shaft and making it more susceptible to damage.

Scalp Care During a Heatwave: Prevention is Key

A healthy scalp is the foundation of healthy hair. During a heatwave, prioritizing scalp care is crucial. Here’s how:

Cooling Scalp Treatments

Aloe Vera: Applying pure aloe vera gel can soothe a heated scalp and provide hydration. Its anti-inflammatory properties also help calm irritation.

Peppermint Oil (Diluted): A few drops of peppermint oil mixed with a carrier oil (like jojoba or coconut oil) can create a cooling sensation. Always dilute essential oils before applying to the skin.

Cool Compresses: Gently applying a cool, damp cloth to your scalp for 10-15 minutes can provide immediate relief.

Scalp Mists: Look for scalp mists containing cooling ingredients like cucumber extract or green tea.

Cleansing & Exfoliation

Gentle Shampoos: Opt for sulfate-free shampoos to avoid stripping your scalp of its natural oils.

Frequency: While tempting to wash frequently,over-washing can further dehydrate the scalp. Aim for every othre day, or less if your hair isn’t oily.

Scalp Exfoliation: Gently exfoliating your scalp once a week removes dead skin cells and unclogs follicles, promoting healthy circulation.Use a physical scrub or a chemical exfoliant (like salicylic acid).

Hair Care Strategies for Heatwave Protection

Protecting your hair strands is just as notable as caring for your scalp.

Protective Hairstyles

Braids & buns: These styles minimize sun exposure and reduce friction, preventing breakage.

Headwraps & Scarves: A stylish and effective way to shield your hair from the sun and heat. Choose breathable fabrics like cotton or silk.

Loose Styles: Avoid tight hairstyles that can put stress on the scalp, especially when it’s already sensitive.

Product Choices

Leave-In Conditioners: Provide essential hydration and protection against environmental damage. Look for formulas with UV filters.

Hair Oils: Argan oil, coconut oil, and jojoba oil can help seal in moisture and protect against heat. Apply sparingly to avoid greasiness.

Heat Protectants: If you must use heat styling tools, always apply a heat protectant spray beforehand.

UV Protection Sprays: Specifically designed to shield hair from the damaging effects of UV radiation.

Minimizing heat Styling

Air Drying: Embrace air drying whenever possible to avoid exposing your hair to heat.

Lower Heat Settings: If you must use a hairdryer or styling tool, use the lowest heat setting.

Limit Frequency: Reduce the frequency of heat styling to minimize damage.

Recognizing & Addressing Heat-Related Hair Damage

Even with preventative measures, heat damage can occur. Here’s what to look for:

Increased Breakage: Noticeably more hair falling out than usual.

Split Ends: A sign of dryness and damage.

Dryness & Brittleness: Hair feels rough, straw-like, and lacks shine.

Faded Color: Heat and sun exposure can cause hair color to fade quickly.

Scalp Burn: Redness, pain, and sensitivity on the scalp. Seek medical attention if you suspect a scalp burn.

Repairing damaged Hair

Deep Conditioning Treatments: Regularly use deep conditioning masks to replenish moisture and repair damage.

Protein Treatments: Help strengthen and rebuild the hair shaft. Use these sparingly, as overuse can lead to brittleness.

Trim Split Ends: Regular trims remove damaged ends,preventing further breakage.

Hydrating Masks: Masks with hyaluronic acid or glycerin can draw moisture into the hair.

Real-World Example: The 2023 european Heatwave & Hair Concerns

During the intense 2023 European heatwave, dermatologists across the region reported a significant increase in patients presenting with scalp sunburn and heat-related hair damage. Many individuals underestimated the impact of prolonged sun exposure on their scalps, even when wearing hats. This
