Premature Graying of Hair: A Comprehensive Review and Recent Insights

    Kavita Poonia, Mala Bhalla
    TLDR Premature graying of hair is mainly caused by genetics, stress, and environment, with potential treatments being explored.
    Premature graying of hair (PMGH) is influenced by genetic, environmental, and biochemical factors, with oxidative stress and reactive oxygen species (ROS) playing a key role in disrupting melanocyte function. Genetic deficiencies, such as in BCL-2 and MITF, and external factors like UV radiation and smoking, contribute to PMGH. There are mixed findings on the association between PMGH and systemic diseases like cardiovascular issues. Current treatments, including oral supplements and topical solutions, show inconsistent results, with relapse being common. Emerging treatments focus on oxidative stress and genetic factors, with future therapies potentially involving stem cell approaches and new drugs, though more research is needed.
