Beat the Heat This Summer by 'Dyeing It Cool' with High-Tone Colors! got2b Releases a Web Movie Focusing on Temperature Differences Caused by Hair Color!

Cool Color Key Visual 'got2b,' a hair cosmetics brand that incorporates salon techniques and knowledge into home care products, released a web movie titled 'Dye It Cool This Summer' on April 22, 2026 (Wednesday). The movie introduces a new proposal called 'Cool Color' for spending the summer comfortably, based on verification results of temperature differences caused by hair color. In the coming season, the sunlight will grow stronger, and the summer heat will hit in full force. While standard heat countermeasures like hats, parasols, and cooling goods are indispensable, got2b focused on a slightly surprising perspective: 'hair color.' In a test comparing hair surface temperatures, the results showed that black hair can be up to 13.05°C hotter than blonde hair. There was a new discovery that the brighter the hair color, the less heat it traps. Therefore, got2b proposes 'Cool Colors,' which look visually refreshing as well. Dyeing your hair in a high tone is a new option for heat mitigation, helping you stay comfortable during the summer while enjoying hair color as a fashion statement. To mark this, we have released the web movie 'Dye It Cool This Summer,' where you can visually experience the world of 'Cool Colors.' We present this new heat-relief concept of 'dyeing' in a stylish video typical of got2b. Enjoy hair color as if you are wearing coolness. How about adopting 'Cool Colors,' which combine fashionability and heat mitigation, this summer? Web Movie 'Dye It Cool This Summer' Released Set against a midsummer blue sky, this movie begins with the message, 'Dyeing: A Heat Countermeasure.' Despite being in a midsummer landscape where the heat is prominent, five women appear somewhat light and cool. The reason is their 'High-Tone Colors.' This movie uses striking visuals to express the 'temperature difference from black hair' created by each high-tone color: silver, lavender, blonde, milk tea, and pink. The numbers floating in the video are real data showing the 'difference in hair surface temperature' compared to black hair. The difference in temperature rise captured by a thermographic camera visually conveys the 'coolness' unique to high-tone colors. And it concludes with a strong final message: 'Dye It Cool This Summer.' Through this movie, we fashionable and stylishly expressed how hair color can provide a new option for summer heat mitigation. Video Title: 'Dye It Cool This Summer' Edition Video URL: https://youtu.be/ZUxGu9vzKzw Special Site URL: https://got2b.jp/campaign/coolcolor/ Cuts from the 'Dye It Cool This Summer' Edition Does Hair Surface Temperature Change Depending on Hair Color?! Verification Results Revealed! Under the blazing midsummer sun. What happens to the temperature of the head, which receives direct sunlight and easily traps heat? Prompted by this question, we actually measured the temperature of the head (surface of the hair) to verify and compare whether differences occur depending on the color. Comparing the surface temperature of 6 types of wigs (black hair and 5 types of colored hair) under an outdoor temperature of 36.4°C, it was found that the hair surface temperature differs depending on the hair color! Surprisingly, blonde hair showed a result of being up to 13.05°C lower than black hair 20 minutes after measurement began. A trend emerged that brighter hair colors tend to trap less heat from direct sunlight. When exposed to sunlight for 20 minutes under the same conditions, blonde was 13.05°C lower than black hair Changes in hair surface temperature under an outdoor temperature of 36.4°C 1. The brighter the hair color, the more the rise in hair surface temperature is suppressed. Compared to black hair, high-tone colors like blonde, pink, silver, and lavender resulted in a lower overall temperature increase. 2. The temperature difference due to color differences widens over time. Under continuous exposure to direct sunlight, a trend was observed where the difference between black hair and bright hair colors grew larger over time. 3. A maximum temperature difference of 13.05°C occurred between black hair and blonde hair. Twenty minutes after the start of measurement, a maximum difference of 13.05°C was recorded between black hair and blonde hair. The magnitude of the impact that hair color differences have on the temperature environment was substantiated. [Experiment Overview] ・Implementation Period: September 2025 ・Outdoor Temperature / Humidity: 36.4°C / 60% ・Measurement Time: 13:00 ・Experiment Method: 6 wigs (a black hair wig, an existing bleached wig, and wigs dyed using our company's products) were set outdoors at a temperature of 36.4°C and a humidity of 60%. The hair surface temperature was measured at 25 locations each after 3 minutes, 10 minutes, and 20 minutes, and the values were averaged. *This experiment concerns 'hair surface temperature'.
