Fact or Fiction: Can Stress Cause Gray Hair?

By: Cristina Montemayor | Aug 03, 2022

Stress is known as the "silent killer." It's a key risk factor for heart disease and stroke, which is something to keep an eye on as you age. Stress is also suspected of causing gray hair, but is it true? VEGAMOUR dug into the research and talked to an expert to determine if stress can cause gray hair. Plus, find out what products you should use to combat graying strands from the inside out.

Can Stress Cause Gray Hair?

It's an old wives' tale that stress causes gray hair, but is there any truth to this widely believed myth? Before we dive into that answer, it's important to understand the role that stress plays in the body.

Stress activates your sympathetic nervous system, which contributes to what is known as the "fight or flight" response. This signals the adrenal to release hormones called adrenalin (epinephrine) and cortisol, as well as the stress hormone corticosterone.

"[When] your body is in a fight or flight mode, it releases high levels of cortisol and affects the hair follicle," said Katelyn Ellsworth, lead stylist, color and extension expert and founder of The Roslyn Salon in San Diego, California. "The stress can affect the scalp health and ultimately the hair cycle and hair follicle, which can result in more gray hair. The melanin (color part of your hair) is reduced in this case, which is when you see the gray."

Hormones have a huge impact on your hair health, so it's actually not a huge leap to assume that stress can turn hair gray. Your sympathetic nervous system is spread out across the body, including at the base of the hair follicle. Stress hormones cause pigment-producing cells to activate prematurely, depleting the hair's “reserves” of color.

As you age, those reserves are depleted more quickly, which might cause you to gray prematurely. Chronic stress, life stress and psychological stress all have the potential to trigger this snowball into this stress response and lead to graying hair.

What Scientists Are Saying About Stress and Gray Hair

Scientists who study the impact of stress-induced graying confirm what our moms and grandmothers always told us: stress causes gray hair. What conventional wisdom didn't know is that hair graying caused by stress is actually reversible.

It's true: studies show that taking the stress away could actually allow white strands to return to the natural color at the root. Why? Aging is not a linear process that sets you on an irreversible course once it starts. The aging process is slightly malleable and allows for some wiggle room in the right context, whether that means slowing down the aging process or, in some cases, a reversal.

One study found that an increase in stress corresponded with hair graying, which scientists correlated through interviews with the participants. When the participants reported a reduction in stress, like going on vacation or resolving a stressful event, the hair regained its pigment.

Although the results of this study were promising, the sample size was small and more research needs to be done. Timing also plays a key role in this process. If you're around middle age and about to go gray, stress can push you across that threshold faster, but there's also a chance that when you remove that stress, your hair pigmentation could return. If you've been gray for 20 years, it's unlikely that your gray hairs will revert back to their natural state, even if you reduce your stress levels.

Other Ways Stress Can Impact Hair

Stress can affect more than just your hair color. When your body is under stress, it will divert resources from your hair follicles to the rest of your body, which needs the nutrients more than your hair. Your immune and circulatory systems are essential for survival, whereas your hair is not. This can exacerbate hair thinning and shedding and trigger certain types of hair loss that are closely linked to acute and chronic stress: telogen effluvium, alopecia areata and trichotillomania.

Telogen effluvium is a type of hair loss characterized by the sudden and diffuse thinning over the entire scalp, typically triggered by acute stress.

Alopecia areata is an autoimmune condition that occurs when the immune system attacks the hair follicles, resulting in patchy hair loss. According to some studies, trauma or intense stress might increase your chance of developing an autoimmune disease, like alopecia areata.

Finally, trichotillomania is a mental disorder characterized by a compulsive impulse to pull out hair in your scalp, eyelashes, eyebrows or any other part of the body. For some people, extreme stress could trigger trichotillomania.

How to Address Gray Hair Caused By Stress

Avoiding stress completely isn't an option for most people, but reducing stress is possible no matter your lifestyle — and it can have compounding effects on your overall health and wellness. By incorporating a few strategies and lifestyle changes into your daily routine, you'll be ready to handle any stress that happens to come your way. Here are a few easy strategies for dealing with stress:

Eat healthy, whole foods: A well-balanced diet gives your body the nutrients it needs to work effectively. Aim for color and variety and avoid skipping meals, which can cause your blood sugar to spike.
Exercise: Daily exercise can help relieve tension and elevate your heart rate, which your body and mind in sharp form. (Always ask your doctor before starting a new exercise program if you have preexisting conditions.)
Meditate: A daily meditation practice can do wonders for your health, including mental and emotional health. A few minutes of meditation per day can help clear the mind, improve mood, boost brain function, reduce stress, slow down the aging process and support a healthy metabolism.
Prioritize sleep: The body and mind recover while you sleep, which is necessary to operate at peak performance. Strive to get eight hours of sleep per night.
