Trichologist Eva Proudman, noted in recent health discussions, emphasizes that adopting healthier daily habits can help support natural hair color for a longer period. A growing body of expert guidance suggests reducing harmful behaviors, limiting sun exposure without protection, and ensuring sufficient vitamin B12 intake may contribute to maintaining hair vitality and pigment retention over time.
Experts explain that toxins found in cigarettes and alcoholic beverages can trigger oxidative stress in the body. This process involves unstable molecules called free radicals attacking healthy cells, potentially affecting pigment-producing cells responsible for hair color. When these pigment cells are stressed or damaged, melanin production can decline, which may ultimately influence how hair color holds up with age. This is one reason why a lifestyle focused on reducing toxins is often linked with healthier-looking hair in the long run.
The impact of ultraviolet (UV) exposure is another factor in hair health. Prolonged sun exposure can drive oxidative stress and, at the same time, degrade keratin—the primary protein that forms the structural framework of each hair strand. Over time, excessive UV radiation may lead to hair that feels coarser and looks drier, with reduced overall quality. Wearing a hat or using sun protection can help shield hair from these effects, supporting stronger strands and a more consistent appearance of color during sunny months.
Vitamin B12 plays a key role in cellular renewal, including the activity of melanocytes, the cells that produce pigment. A diet rich in B12 supports the regeneration of these cells, which can help preserve natural hair color as part of an overall healthy eating pattern. Foods that provide B12 include animal-derived products such as meat, eggs, and dairy, making balanced dietary choices important for those seeking to maintain color integrity over time. In addition to B12, a varied intake of nutrients that support hair health—proteins, iron, and zinc—can contribute to the strength and resilience of hair strands.
Historical observations and modern research alike have explored how lifestyle factors relate to hair characteristics across populations. Some cultural anecdotes have linked hair length and styling traditions to broader social and lifestyle patterns, though contemporary science emphasizes a multifactorial view. Genetics, nutrition, environmental exposures, and aging all interact to shape how hair color and texture evolve. For individuals aiming to support their hair’s natural color and vitality, a holistic approach that combines nutrient-rich nutrition, sun protection, and avoidance of excessive toxins is often recommended. The dialogue among dermatology and trichology experts continues to refine practical guidance that people can integrate into daily life, with ongoing attention to personal health and well-being as central goals.
