What Causes White Hair? Can I Prevent It?
While everyone will eventually get white hair, it can be a bit distressing to spot that first gray strand. For many, white hair is the first visible sign of aging �?and often, the first thing they wish to reverse.
On average, hair begins to turn white between the ages of 30 and 40, though some people experience it much earlier.
The medical term for white hair is canities.
Why Does Hair Turn White?
Hair turns gray or white when the hair follicles stop producing melanin. Melanin is the pigment responsible for the color of your skin and hair.
Hair goes through a cycle of growth, rest, and shedding. Each time a new hair cycle begins, melanin is produced in the hair. This cycle lasts several years, and after 7 to 15 cycles, melanin production slows or stops, causing the hair to lose its color.
Does Stress Cause White Hair?
Yes, stress can speed up the process of graying. Research shows that stress can accelerate signs of aging, including the appearance of white hair.
When you’re stressed, your body triggers a “fight or flight” response, releasing a hormone called norepinephrine. This hormone causes the melanocytes (cells that produce melanin) to leave the hair follicles, which in turn leads to the growth of white hair.
There are many factors that can influence how quickly your hair turns white, such as family history, underlying health conditions, and an unhealthy lifestyle.
My Hair Is Turning White �?Can I Stop It?
Premature white hair is difficult to treat. Currently, there is no medical solution to reverse the graying process. However, if you have a condition that could affect your hair color, such as a vitamin deficiency, a dermatologist or primary care doctor can help develop a treatment plan.
White hair is a natural part of aging, and there is nothing wrong with it. However, if white hair affects your self-esteem, you can cover it with hair dye.
There are two types of hair dye:
- Natural Dyes: Like henna, these are gentler on the scalp than synthetic dyes, but they typically fade faster, requiring more frequent touch-ups.
- Synthetic Dyes: Permanent or semi-permanent synthetic dyes last longer and are easier to use than temporary ones. However, certain ingredients in long-lasting dyes may irritate the scalp or cause skin allergies.
When choosing a hair dye, consider whether you have sensitive skin and check the ingredients in the product.
Some people suggest plucking white hairs, but be aware that this can cause thinning hair, and plucked hairs will likely grow back as white.
Studies suggest that white hair may regrow with color, depending on factors such as stress reduction or treatment for underlying health issues. More research is needed to determine whether white hair can be reversed.
How Can I Slow Down the Process of White Hair?
While researchers are still looking for ways to reverse white hair, you can slow down the process by making certain lifestyle changes. As with hair loss, the earlier you start addressing it, the more effective the results. Keep in mind that these are temporary measures and will not fully stop the graying process.
Dermatologists suggest that the following habits may help delay the onset of white hair:
- Maintain a healthy lifestyle
- Eat a balanced diet rich in antioxidants, vitamins, and minerals
- Get enough sleep
- Avoid smoking
- Try to manage stress
A board-certified dermatologist can diagnose and treat underlying conditions that cause white hair and help create a treatment plan tailored to your needs.
