A new study suggests a link between grey hair and cancer risk, indicating that the process of hair greying, driven by stress and DNA damage in melanocyte stem cells, may be a protective response to prevent harmful mutations that could lead to cancer, although bypassing this mechanism might increase melanoma risk.
Emerging research suggests that grey hair may be an outward sign of the body's protective response against cancer, with damaged melanocyte stem cells either undergoing differentiation and disappearing (causing grey hair) or bypassing this process and potentially leading to melanoma, highlighting a complex link between aging, cellular damage, and cancer risk.
A leading expert in hair care reveals that while genetics largely dictate the rate at which hair turns grey, there are ways to slow down the process, including managing stress, protecting against UV rays, and ensuring a balanced diet with essential nutrients like vitamin B12 and selenium. Factors such as smoking, sun exposure, and chronic stress can accelerate greying, while conditions like coeliac disease and underactive thyroid can also contribute. Personal anecdotes and expert advice suggest that lifestyle choices and dietary supplements can play a role in maintaining natural hair color.
Statins and blood pressure medication are crucial for reducing the risk of heart disease, but in rare cases, they can cause kidney problems. Chronic kidney disease can also be caused by high blood pressure and diverticulitis can cause on-and-off pain in the lower abdomen. Managing chronic pain with medication shortages can be frustrating, but exploring alternative treatments such as anti-inflammatories and nerve painkillers may help. Increasing fiber intake, staying hydrated, and exercising can help manage diverticulitis symptoms. Additionally, the UK Global Health Insurance Card offers similar benefits to the European Health Insurance Card for UK citizens traveling in the EU and some other countries.
The process of hair turning grey is linked to the pigment melanin, with stress being a potential factor in premature greying. Vitamin deficiencies and medical conditions can also accelerate greying. While hair dyeing is a temporary solution, maintaining a healthy lifestyle, including avoiding smoking and managing stress, is recommended. However, the efficacy of products claiming to slow greying remains uncertain, as does the impact of natural therapies.
As we age, our bodies go through some awkward changes such as unexplained aches and pains, grey hair in weird places, random anxiety attacks, forgetfulness, uncomfortable dryness, loss of tolerance and patience, falling face, and moles and age spots. These changes are a part of the aging process and can be managed with proper care and attention.

Jennifer Aniston promoted her new LolaVie hair treatment on Instagram, showing off her natural grey hair roots in a casual yet chic ensemble. Fans praised her for allowing her grey hair to come through. Aniston also recently mourned her dog, Dolly, on Instagram and has been spending time with celebrity friends including Julia Roberts, Drew Barrymore, and Kathy Najimy. She recently promoted Murder Mystery 2 with co-star Adam Sandler in Paris.
Scientists have discovered that melanocyte stem cells become stuck inside the hair follicle and are unable to produce pigment, causing hair to turn grey as we age. The pigment-producing part of a stem cell changes as the hair ages, sheds, and grows back. The stem cells get stuck in a part of the hair follicle called the hair follicle bulge, failing to mature into fully-fledged melanocytes. The researchers suggest that their findings could open up a potential way to reverse or prevent grey hair by helping jammed cells to move again between developing hair follicle compartments.
Scientists have discovered that stem cells may get stuck as hair ages, resulting in greying hair. The study focused on melanocyte stem cells in mice and found that as hair ages, increasing numbers of these cells get stuck in the stem cell compartment of the hair follicle bulge, where they remain. The researchers suggest that if their findings hold true for humans, it could open up a potential way to reverse or prevent grey hair by helping jammed cells to move again between developing hair follicle compartments.
Scientists from New York University have discovered that hair turns grey as we age due to pigment-making cells losing the ability to mature. The team studied the process in mice and found that stem cells become "stuck" in limbo, failing to mature into fully-fledged melanocytes, which give hair its natural colour or shade. The researchers believe that the same fixed-positioning of melanocyte stem cells may exist in humans, presenting a potential pathway for reversing or preventing greying. The study could also help our understanding and treatment of certain cancers and other medical conditions.
Scientists have discovered that stem cells become immobile in hair follicles as we age, resulting in the loss of pigment cells and the greying of hair. The study, conducted on mice, found that the number of hair follicles with immobile stem cells increased from 15% in young hair to over 50% in older hair. The researchers believe that this discovery could lead to treatments that restore mobility to these stem cells and prevent or reverse greying hair in humans.
