This segment discusses why men are getting white hair at increasingly younger ages, with some individuals under 25 already showing white hairs. The primary explanation offered is stress. The pressure from studies, work, and social networks directly impacts the cells responsible for hair color. These cells become more active, leading to the hair growing white. Another contributing factor is fatigue, stemming from an intense lifestyle and insufficient sleep. This can signal the body to alert researchers to deficiencies in essential minerals like iron, zinc, and copper. These minerals are crucial for melanin production, the pigment that gives hair its color. When melanin is lacking, white hair grows. The discussion also touches on the age of a singer named Marcel Amon, humorously contrasting his presumed age with the age of someone's grandmother. The radio show itself is described as "Radio Arc-en-Ciel," and the hosts express their enjoyment of the segment, even referencing a song about the sky. The overall tone is lighthearted and conversational, exploring a common observation about premature graying.
