Koizumi Seiki Co., Ltd. (Headquarters: Bingo-cho, Chuo-ku, Osaka; Representative Director and President: Naoshi Hashimoto), which plans and develops its own beauty and grooming products and acts as an agent for domestic and international manufacturer brands, conducted new verification tests on the UV protection effects of its 'Reset Brush' in preparation for the upcoming summer season when UV radiation becomes severe.
Intensifying UV Radiation Year by Year
According to data on UV radiation published by the Japan Meteorological Agency, 'strong' levels of UV radiation have been observed daily in some regions since late March this year. Compared to the annual average, UV levels rapidly increase particularly from April to June, reaching levels comparable to mid-summer in some areas, with a trend of 'very strong' UV levels recorded on average in July and August.
Furthermore, the 'Intense Heat Report' released by the Japan Weather Association predicts that 7-14 locations nationwide will experience 'extreme heat days' (days with a maximum temperature of 40°C or higher) this year, suggesting a possibility similar to or slightly higher than the average over the past 10 years. Especially after the rainy season, caution against extreme heat days is necessary in Eastern and Western Japan, and attention to UV radiation is also increasing. Early UV protection measures are recommended nationwide.

Effects of UV Radiation on Hair
It is widely known that UV radiation damages the skin, but hair is also affected by UV rays in the same way. When hair is exposed to UV radiation, the amount of moisture contained within the hair decreases (*). A decrease in moisture makes hair prone to various damages such as cuticle damage, dryness, dullness, and frizz (*). Early care is especially important from spring to summer when UV radiation rapidly increases.

Consumer Awareness Survey on UV Radiation
■Survey on Summer UV Protection
74% of people used sunscreen etc. for UV prevention. 46.4% took UV protection measures other than hats/parasols.
→While about 75% take preventive measures for skin, direct preventive measures for hair fall below half.
■Aftercare after UV Exposure
41.6% of people performed aftercare on their skin after UV exposure. 22% performed aftercare on their hair after UV exposure.
→More than 40% of people perform aftercare for skin, but only 20% for hair, with about 80% doing no care.
