As life's demands intensify, many of us find ourselves grappling not only with the stress of deadlines and responsibilities but also with an unexpected and often unwelcome companion – premature greying of hair.
While it has long been contemplated whether stress turns your hair grey, a 2021 study by Columbia University found that it is true. Here's how it happens.
Stress Causes Hair To Turn Grey
Hair colour is determined by pigments called melanin, produced by pigment-producing cells known as melanocytes. When these melanocytes become less active or die off, the hair loses its colour and turns grey or white.
The 2021 study published in eLife attributed stress as one of the factors that can damage melanocytes:
- Oxidative Stress: Stress triggers the production of free radicals in the body, leading to oxidative stress. This oxidative stress can damage melanocytes, accelerating their ageing process and, consequently, promoting premature greying.
- Hormonal Fluctuations: Stress activates the release of stress hormones like cortisol, which can disrupt the normal functioning of various bodily systems, including the regulation of melanocytes.
- Inflammation and Hair Follicle Damage: Stress-induced inflammation can affect the hair follicles, causing damage that may impact the health of melanocytes.
- Genetic Predisposition: Individuals with a family history of early greying may be more susceptible to its occurrence, even under lower stress levels.
Can Premature Hair Greying Be Reversed?
The study's senior author Martin Picard, PhD, associate professor of behavioural medicine, at Columbia University Vagelos College of Physicians and Surgeons said, "Our data add to a growing body of evidence demonstrating that human ageing is not a linear, fixed biological process but may, at least in part, be halted or even temporarily reversed.”
In simple words, the study found that it may be possible to reverse, or at least stop premature greying due to stress. Here are a few strategies you can employ:
- Stress Management Techniques: Incorporate stress-reducing practices into your daily routine, such as meditation, deep breathing exercises, or yoga, to mitigate the impact of chronic stress.
- Balanced Diet: Consume a nutrient-rich diet that includes vitamins and minerals essential for hair health. Foods rich in antioxidants can combat oxidative stress.
- Adequate Sleep: Prioritise quality sleep to allow your body to repair and regenerate.
- Regular Exercise: Engage in regular physical activity to promote circulation and reduce stress.
- Hair Care Practices: Adopt gentle hair care practices, avoiding excessive heat and chemical treatments. Use nourishing hair products that promote overall hair health.
While premature greying may be an unwelcome sign of stress, understanding the intricate relationship between stress and hair colour provides an opportunity for proactive lifestyle changes. So, as the silver strands weave their tales, let them be a reminder of resilience and the journey towards well-being.
