Koizumi Seiki Corporation (Headquarters: Bingo-machi, Chuo-ku, Osaka; Representative Director and President: Naoshi Hashimoto), which plans and develops its own beauty and grooming products and operates as an agency selling domestic and international manufacturer brands, has conducted new verification on the UV protection effects of its "Reset Brush" in preparation for the full-fledged summer UV season.
**Increasing Intensity of UV Rays Year by Year**
According to "UV Data" published by the Japan Meteorological Agency, "strong" levels of UV radiation have been observed daily in some regions since late March this year. Based on cumulative annual averages, UV levels sharply increase, especially from April to June, reaching levels comparable to midsummer in some areas. The trend of "very strong" UV levels being recorded on average continues from July to August.
Furthermore, the "Extreme Heat Report" announced by the Japan Weather Association predicts that this year, a total of 7 to 14 locations nationwide are expected to record extreme heat days (days with a maximum temperature of 40°C or higher), indicating a possibility of being similar to or slightly higher than the average of the past 10 years. Particularly after the rainy season, vigilance against extreme heat days is required in Eastern and Western Japan, and attention to UV radiation is also increasing. Early UV protection measures are recommended nationwide.

**Impact of UV Rays on Hair**
It is widely known that UV rays damage the skin, but hair is also affected by UV rays in the same way. When hair is exposed to UV rays, the amount of moisture contained within the hair decreases (*). When moisture decreases, various damages such as cuticle damage, dryness, loss of shine, and frizz are more likely to occur (*). Especially from spring to summer, when UV levels sharply increase, early care is important.

**Consumer Awareness Survey on UV Rays**
■ Survey on Summer UV Protection
74% of people used sunscreen or other methods for UV prevention. 46.4% of people took UV protection measures other than hats or parasols.
→ While approximately 75% of people took preventive measures for their skin, less than half took direct preventive measures for their hair.
■ After-care after UV Exposure
41.6% of people performed after-care on their skin after UV exposure. 22% of people performed after-care on their hair after UV exposure.
→ More than 40% of people performed after-care for their skin, but only 20% did so for their hair, with approximately 80% doing no care.
