Dr. Xand, a familiar face on BBC’s Morning Live, has shed light on the role of stress in the premature greying of hair. According to the expert, stress can negatively impact the cells responsible for producing hair pigment, leading to the emergence of grey or white hair.
In a breakthrough study led by Dr. Ya-Chieh Hsu of Harvard University, the impact of stress on hair graying was further explored using mice as subjects. The research revealed that exposure to various forms of stress, including physical discomfort and psychological stress, led to a noticeable loss of melanocyte stem cells and subsequent hair greying.
While examining potential causes, the study ruled out immune attack and stress hormone levels as direct contributors to stress-induced hair graying. Instead, the focus turned to the neurotransmitter noradrenaline, identified as a key factor in the process.
