In mouse skin cells that aren't dividing, a protein called DGUOK helps keep important energy-related genes working properly. If DGUOK is removed, those genes slow down, and the energy factories in...
In mice with a genetic problem that causes gray hair, giving them an antioxidant called NAC in their water seems to help keep their fur from turning gray by protecting the cells that give hair its...
When a certain gene is turned off in hair color cells in mice, their fur starts to gray early because the cells die off — but the ones that survive can still make pigment just fine.
Sometimes, multiple hairs on the same person's head go grey or even regain color at the same time — this might mean the body's internal systems are controlling hair color changes together.
When gray hair starts to regain color, it happens just as fast or a bit faster than when it turned gray in the first place — sometimes in just days or weeks.
When people go through stressful times, their hair might start to grey — and when stress goes down, some might actually see their hair regain color. This has been noticed to happen around the same...
When your hair turns grey, the cells in the hair might be changing how they use energy and protect themselves, turning up certain proteins that help with these jobs.
Some people's gray hairs can naturally turn back to their original color, and this can happen to anyone — no matter their age, gender, or where the hair is on the body.
Keeping energy levels healthy in hair cells helps protect the cells that give hair its color, so they don’t die off too soon.
Stress might be turning your hair gray by messing with your cells, and relaxing could help your hair get its color back.
Taking NR and CoQ10 supplements might help your cells produce energy better, reduce damage and swelling, and create the right environment for your body to keep making skin pigment over time.
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...
