Using antioxidant-rich products on your skin or taking them as supplements might help turn some gray hairs back to their original color by protecting hair roots and helping pigment cells work better.
Stress might turn your hair gray, but if you reduce that stress, your hair could actually regain its color again.
When the energy factories in our cells don't work right, they leak harmful particles that can damage hair color cells and cause gray hair to show up too early.
Your hair needs energy from tiny power plants in cells (called mitochondria) to keep making pigment — without healthy mitochondria, your hair can't stay colored over time.
Your hair color depends on special stem cells in your hair roots, and long-term stress from inflammation or oxidation can mess them up, making them disappear or mature too soon.
Gray hairs have more damaging chemicals like hydrogen peroxide and less of the protective enzymes that normally keep those chemicals in check.
Going gray isn’t just about getting older — it’s because of damage from stress inside the hair roots, where too much hydrogen peroxide builds up and the body can’t fight it off anymore.
This lifestyle program doesn’t change your overall DNA methylation much, but it tweaks it in smart ways to make your cells look younger — like turning back the clock in specific spots instead of...
If healthy guys in their 50s and 60s cut back on carbs and exercise every day for 8 weeks, their blood fat levels might drop by a quarter — showing that small lifestyle changes can make your body...
Eating foods high in folate and taking a specific probiotic might boost the body's active form of folate by 15% in healthy middle-aged guys—no pills needed.
Healthy men in their 50s and 70s might be able to slow their biological aging in just 8 weeks by making big lifestyle changes, like better diet and exercise — one study saw cells look about 2 years...
Doing a mix of healthy eating, exercise, better sleep, and stress relief for 8 weeks might actually turn back the clock on aging in middle-aged men — by about 3 years on a biological level.
Taking a supplement called nicotinamide riboside for six weeks might change how genes work in the blood of people with moderate to severe kidney disease, possibly affecting how the body handles...
Taking 1200 mg of coenzyme Q10 every day for six weeks might help lower inflammation in adults with moderate to severe kidney disease.
Taking a supplement called nicotinamide riboside for six weeks might help immune cells in people with kidney disease work better by boosting their energy levels.
Taking 1200 mg of CoQ10 every day for six weeks might help reduce harmful stress in the body for adults with moderate to severe kidney disease.
Taking a supplement called nicotinamide riboside every day for six weeks might help reduce harmful stress in the body for adults with moderate to severe kidney disease.
Some natural stuff like vitamins, plant chemicals, and compounds from cannabis might help protect skin cells from damage by balancing antioxidants and reducing inflammation — but we don’t have strong...
When skin pigment cells are under constant stress from unstable molecules, it can throw off their balance, mess up skin color, and lead to conditions like vitiligo or dark patches.
There’s a built-in system in pigment cells that turns on protective genes when they’re under stress from harmful molecules, helping them stay healthy and avoid damage.
The cells in your skin that give you your color are especially at risk from sun damage and natural byproducts of pigment production, which can harm the cells and possibly lead to skin cancer or...
As we age, pigment cells in our hair can go haywire and stop working properly — this might be sped up if there's a glitch in a key gene called MITF that controls how these color cells develop.
In mice, when a specific gene called Bcl2 isn't working, the stem cells that make pigment die off when the hair cycle pauses, but the mature pigment cells stay alive — showing that stem cells really...
Going gray might happen because the stem cells that keep your hair colored stop working properly as you age, according to studies in people and specially tagged mice.
