Scott Douglas Jacobsen: What is hair whitening?
Eliza Pineda: Hair whitening or hair graying is when hair strands lose pigment and turn into a white or gray shade. This usually happens as a sign of aging but it can also occur prematurely due to other factors.
Maria Jones: Whitening of hair, more commonly known as premature graying, is characterized by the loss of melanin production by melanocytes in the hair follicles. It ultimately results in gray or white hair. It generally begins in early adulthood and progresses slowly, though it may start earlier in some people. The natural color of the hair is lost due to the reduced amount of melanin production. This reduction in melanin production can be brought about by several factors, which include genetics and environmental influences.
Dr. Viktoryia Kazlosukaya: Hair whitening is a natural process when hair stops producing pigmentation.
Dr. Ross Kopelman: As a hair surgeon, I explain to my patients that hair whitening, commonly referred to as graying, occurs when the melanocytes within the hair follicles stop producing melanin, the pigment responsible for hair color. When melanin production decreases or stops, hair appears white, gray, or silver. This process is a natural part of aging, but when it happens prematurely, before the age of 30 for Caucasians or 40 for those of African or Asian descent, it’s often linked to genetic, environmental, and lifestyle factors.
Jacobsen: What genetic factors contribute to premature hair whitening?
Pineda: Genes such as the IFR4 gene can contribute to how the body makes melanin, the pigment needed to produce your natural hair color. It’s also a common occurrence for families to be predisposed to gray hair, premature gray hair, and hair loss. If you see a lot of relatives with gray hair, chances are, you have got the white hair gene.
Jones: Genetics indeed determine to a large extent the time and degree of premature whitening of hair. Variations in genes that govern the function of melanocytes in hair follicles may be responsible for an early depletion of melanin-producing cells, leading to graying. A family history of the condition is considered the most telling indicator: if one or both parents had early graying, then their children also are likely to do so. However, it is also due to genetic mutations and changes in individual body responses that influence hair whitening at different times of life.
Kazlosukaya: The genetic mechanisms behind hair whitening are highly complex, with over 60 genes recently identified as potentially playing a role. While many of these genes have been studied, and researchers can now investigate hair whitening in the lab by “switching on and off” various genes, the full picture is still under investigation. https://www.sciencedirect.com/science/article/pii/S1568163723001368
Kopelman: Genetics play a significant role in determining when someone will start to see gray or white hairs. If your parents experienced premature graying, you are more likely to experience it as well. Certain genes, such as IRF4 and TGF-beta, regulate how long melanocytes remain active in the hair follicles. For some individuals, these genes trigger an earlier burnout of melanocytes, leading to premature whitening. There is still ongoing research into the exact genetic mechanisms that influence when graying begins, but we know that heredity is a dominant factor in many cases of early pigment loss.
Jacobsen: How do environmental and lifestyle factors influence melanin production in hair follicles?
Pineda: Healthy hair is pigmented hair. If the hair gets damaged in any way or your health suffers, this can contribute to the slowing down or even complete halt of melanin production in your hair. Factors such as sun damage, heat damage, smoking, and health issues can all have a stake in causing white hair.
Jones: A number of factors may be the reason for poor melanin production in human hair follicles. Environmental factors like excessive smoking, extensive exposure to sunlight, or pollution, coupled with insufficient diet, have been responsible for the cause of oxidative stress in human life. Apart from that, certain lifestyle choices also affect melanin production, including chronic stress and a lack of proper nutrition. Nutrient deficiencies, especially in vitamins like B12, iron, and copper, can disrupt the normal functioning of hair follicles and melanin production, which could be one of the reasons for premature whitening.
Kazlosukaya: Environment and lifestyle definitely play a role in premature graying. Oxidative environmental stress can impact hair through the production of free radicals. A healthy diet is essential, as premature whitening can occur with protein deficiency, iron-deficiency anemia, and deficiencies in vitamins (such as Vitamin B12) and minerals (including copper, zinc, iron, and calcium).
Kopelman: Environmental stressors, such as pollution and UV exposure, increase oxidative stress, which can damage the melanocytes in the hair follicles and accelerate the depletion of melanin. Lifestyle factors also play a role—frequent use of heat-styling tools, chemical treatments, and poor scalp care can contribute to oxidative stress and hasten the whitening process. When patients come in with concerns about early graying, I make sure to assess their exposure to these types of external factors, as they can have a significant impact on how early and how quickly the hair loses pigment.
Jacobsen: Can hair whitening be reversed or slowed through dermatological treatments?
Pineda: In short terms, yes. Research has been done to create treatments that can effectively reverse white hair by stimulating pigment production in the scalp. However, do note that results vary for each individual.
Jones: Hair whitening is a natural process in the aging cycle, but it can be slowed down through dermatological treatment in some instances. While there are no treatments that completely reverse graying, a variety of products exists to help deal with or camouflage gray hair, including topical treatments and hair dyes. Other treatments, which may include those that stimulate melanin production or promote the health of hair follicles, have shown promise in slowing down the whitening process, but their effectiveness can vary from person to person. Researches are still being carried on for the reversal of whitening of hair through stem cell and other sophisticated treatments.
Kazlosukaya: If there is an identifiable cause, it is theoretically possible to address it. Interestingly, there are reports suggesting that trauma might lead to repigmentation. For example, one case report described the repigmentation of gray hair following surgical wound healing. This observation has sparked interest in regenerative treatments such as microneedling, platelet-rich plasma (PRP), and exosomes. However, these approaches are still under investigation.
Kopelman: While there is no permanent way to reverse hair whitening, it can sometimes be slowed, depending on the underlying cause. Antioxidant-rich topical treatments and supplements can help protect melanocytes from oxidative damage. There is also promising research on peptide-based therapies aimed at supporting melanocyte function in the hair follicle, though these treatments are still largely experimental. In some cases, platelet-rich plasma (PRP) treatments, which are used to improve follicle health, may show some benefit in supporting pigment retention. Topical serums containing ingredients like melatonin or procyanidin have shown some potential to support pigment production, though individual results vary.
Jacobsen: Do stress and nutrition play roles in the premature graying of hair?
Pineda: It’s been found that certain genes like the IFR4 contribute to predicting what age a person will go gray. However, while genetic markers are associated with some whitening of hair, the accuracy is limited and cannot be relied on completely. Other factors such as lifestyle and health should also be considered.
Jones: Yes, both stress and nutrition play a crucial role in the early graying of hair. Chronic stress causes the release of certain types of hormones that include cortisol, known for its adverse effects on hair follicles health and melanin production. Nutritional deficiencies, especially of the essential vitamins and minerals, also have a great impact on hair health and pigmentation. In fact, folic acid, vitamin B12, and iron deficiencies are often associated with early graying. Therefore, a proper diet and reduction of stress should theoretically lower or delay graying.
Kazlosukaya: See above.
Kopelman: Chronic stress plays a significant role in premature hair whitening. Stress raises cortisol levels, which can disrupt melanocyte function and lead to an earlier depletion of pigment-producing cells. I’ve had patients in their 30s who noticed significant whitening after prolonged stressful periods, such as during career changes or family crises. Nutrition also plays an important role. Deficiencies in key vitamins and minerals, such as B12, folic acid, copper, and iron, can impair melanin production and contribute to premature graying. I always emphasize the importance of a nutrient-rich diet that supports overall hair health. While supplements containing biotin, zinc, and vitamin D may not reverse graying caused by genetic factors, they can be helpful in improving overall follicle health and preventing additional damage.
Jacobsen: What are the recent discoveries or innovations in knowledge about the pathways of genetics and epigenetics for premature hair whitening?
Pineda: Yes, stress and nutrition play a huge part in keeping the hairs pigmented. Stress can cause havoc on your health as well as malnutrition as hair relies on your wellbeing and health also. If stress or nutritional deficiencies are causing health issues, it can result in your hair turning white.
Jones: Recent findings from genetics and epigenetic studies have identified molecular pathways at the root of premature hair whitening. These studies have identified several genes that determine the life cycle of melanocytes, one of which is IRF4, a gene associated with the onset of graying. Research in epigenetics has also focused on whether and how these genes can be epigenetically influenced by environmental factors. It follows that even as genetics may lay the blueprint for premature graying, environmental factors such as stress, diet, and pollutants could determine how those genes are expressed and when.
Kazlosukaya: As we delve deeper into the genetics of hair graying, we’ve identified potential molecules that could be targeted to prevent premature graying. However, this area of research is still evolving, and there is much more to learn.
Kopelman: Recent research has highlighted how external factors can influence gene expression related to melanin production. Epigenetic studies have shown that environmental stressors can switch off certain genes responsible for pigmentation, effectively accelerating the hair-whitening process. Scientists are now exploring how these genes might be “reprogrammed” to extend the lifespan of melanocytes. There is also growing interest in the role of mitochondrial health and its connection to graying. Mitochondria are the energy centers of our cells, and some studies suggest that targeting mitochondrial function may help preserve melanocyte activity and delay the onset of hair whitening.
Jacobsen: How can readers prevent or address premature hair whitening through lifestyle changes?
Pineda: It’s always best to maintain a healthy and balanced lifestyle to prevent premature gray hair as well as other signs of aging and health issues.
Lifestyle changes that can really help are quitting smoking, managing stress, maintaining a balanced and nutritious diet, exercising, and taking supplements.
Jones: There are various ways one could avoid or deal with premature whitening of hair through certain adjustments in life. A wholesome diet, abundant in antioxidants, vitamins, and minerals-particularly the B vitamins, iron, and copper-is helpful in maintaining healthy hair and the production of melanin. This would further be helped by the reduction in such stress through practices like mindfulness, yoga, or regular exercises. Chronic stress accelerates the aging processes, including graying. Thirdly, protection against environmental damage-for instance, by wearing hats in the sun or avoiding cigarette smoke-prevents oxidative stress, known to contribute to premature graying.
Kazlosukaya: Stop smoking, healthy diet, prevent stress, regular checkups with the physician.
Kopelman: While genetics can’t be changed, lifestyle modifications can help delay the progression of premature hair whitening. Stress reduction techniques, such as mindfulness practices, regular exercise, and maintaining a consistent sleep schedule, can help regulate cortisol levels and protect hair health. Eating a diet rich in antioxidants from sources like berries, leafy greens, and nuts can help neutralize free radicals and protect melanocytes from oxidative damage. Limiting the use of heat styling tools and avoiding harsh chemical treatments also helps reduce stress on the hair follicles. I always recommend using hair products that provide UV protection to shield the scalp and hair from environmental damage. Scalp care is another important component—using gentle, sulfate-free shampoos and occasionally incorporating scalp treatments helps maintain a healthy environment for the hair follicles.
Jacobsen: What additional resources or experts in genetics might be helpful for articles on hair and dermatology?

Jones: For more insightful information on whitening, it would be ideal to consult geneticists, dermatologists, and specialists in hair. More precisely, this could entail studying the details of the gene pathways that determine color in hair by scholars qualified in molecular genetics. Dermatologists who have specialized in cases of hair loss and aging can indeed offer expert advice on the treatment or slowing down of graying. Consulting experts in epigenetics and oxidative stress could have shed more light on the paper regarding higher environmental aspects that influence hair color.

Kopelman: For anyone looking to dive deeper into the genetics of hair whitening, I recommend exploring research on the IRF4 gene and its role in pigmentation pathways. Journals from organizations like the American Hair Research Society frequently publish studies on the latest findings related to melanocyte function and follicular health. Geneticists who specialize in epigenetics can also provide valuable insight into how environmental factors influence gene expression related to melanin production. I’m always happy to provide additional resources or help connect with experts in these areas to support further exploration of this topic.
