What Can Make Your Hair Turn White?

Noticing strands of white or grey hair in your twenties or thirties can be a confusing experience. While most people expect their hair to change colour with age, early greying or whitening of hair can seem premature. So, what can turn your hair white? Is stress really to blame, or is it just genetics?
In this comprehensive guide, we’ll break down the most common white hair causes, examine the role of stress, and answer questions like “At what age does hair turn white?” We’ll also explore how natural care, a balanced lifestyle, and herbal solutions may help slow down the process.
Understanding the Science of Hair Colour
Hair colour is determined by melanin, a natural pigment produced by specialised cells in your hair follicles called melanocytes. There are two main types of melanin:
-
Eumelanin: responsible for brown and black hair
-
Pheomelanin: responsible for red and yellow tones
As you age or due to various internal and external factors, melanocyte activity decreases. When less melanin is produced, hair begins to appear grey. Once melanin is completely absent, the hair turns white.
Common Causes of White Hair
Let’s explore the most researched and proven grey and white hair causes.
1. Genetics
Genetics is one of the most significant contributors to early greying. If your parents or grandparents experienced premature white or grey hair, there’s a higher likelihood you might too.
In such cases, the process is largely hereditary and may begin in your 20s or 30s, even if you maintain a healthy lifestyle.
2. Natural Ageing
One of the most well-known reasons for white hair is the natural ageing process. Melanocyte activity slows down with age, typically starting in the late 30s or early 40s.
So, at what age does hair turn white? For many people, the first signs of greying appear in the following ranges:
-
Late 20s to early 30s (in genetically predisposed individuals)
-
Mid-30s to early 40s (in most populations)
-
40s and beyond (typical age for the majority)
The pace and pattern of greying can vary widely from person to person.
3. Stress and Psychological Factors
Are white hairs caused by stress? The answer is: potentially, yes.
Recent scientific studies have suggested a link between chronic stress and premature hair greying. Stress can increase the body’s production of certain hormones, which may affect melanocyte stem cells and accelerate their depletion.
High stress levels may also:
-
Reduce antioxidant levels
-
Trigger inflammation and oxidative damage
-
Impairs the body’s ability to repair hair pigmentation cells
While stress may not be the sole cause, it can contribute significantly, especially when combined with other factors.
4. Nutritional Deficiencies
Poor nutrition is another major factor in premature white or grey hair. Deficiencies in specific vitamins and minerals can impair melanin production.
Key nutrients linked to healthy hair pigmentation include:
-
Vitamin B12: Deficiency can lead to early greying
-
Iron: low levels may reduce melanin synthesis
-
Copper: necessary for melanin production
-
Zinc: supports follicle health and pigmentation
-
Folate: helps in cellular turnover and growth
Ensuring a nutrient-rich diet or supplementing under the guidance of a healthcare provider can support overall hair health.
5. Oxidative Stress and Free Radicals
Oxidative stress refers to an imbalance between free radicals and antioxidants in the body. Free radicals can damage DNA, proteins, and cells, including melanocytes.
Over time, oxidative stress can cause:
-
Breakdown of melanin
-
Weakening of hair follicles
-
Accelerated ageing, including premature greying
Environmental exposure to pollution, UV radiation, and chemical products may increase oxidative stress levels, thereby contributing to early hair whitening.
6. Medical Conditions and Hormonal Imbalances
Certain autoimmune and hormonal conditions have been linked to premature white hair. These include:
-
Vitiligo: affects pigment-producing cells, including those in hair follicles
-
Thyroid disorders (hyperthyroidism or hypothyroidism)
-
Pernicious anaemia (related to B12 deficiency)
If you're experiencing sudden or widespread greying, it's a good idea to consult a medical professional to rule out underlying health issues.
Can White Hair Be Reversed?
Once a strand of hair loses its pigment and turns white, it cannot regain its original colour. However, some research suggests that in rare cases, particularly when due to stress or nutritional deficiencies, partial repigmentation might occur if the underlying issue is addressed early.
More importantly, several lifestyle and hair care changes can help slow the progression of greying and improve overall hair quality.
Herbal and Natural Tips to Delay White Hair
While genetics and ageing can’t be changed, you can adopt several strategies to help delay the onset of white hair.
1. Use Herbal Oils Regularly
Herbal, cold-pressed oils rich in antioxidants and essential nutrients can nourish the scalp, improve circulation, and protect hair follicles.
Effective oils include:
-
Coconut oil: helps retain protein and reduce damage
-
Amla oil: known for its high vitamin C content and antioxidant properties
-
Bhringraj extract (if applicable): supports hair colour and growth
-
Curry leaf-infused oil: may help maintain natural pigment
Gently massage the oil into your scalp and hair 1–2 times per week and leave it on for a few hours before washing.
2. Incorporate Herbal Cleansers and Conditioners
Avoid harsh chemic al shampoos and instead opt for herbal hair cleansers that are free from sulfates, parabens, and artificial dyes. Look for ingredients such as:
-
Hibiscus
-
Aloe vera
-
Neem
-
Shikakai
These natural components support scalp health, reduce inflammation, and may help in maintaining melanin levels when used regularly.
3. Eat a Balanced, Nutrient-Rich Diet
To support melanin production and prevent deficiencies that lead to greying, consume foods rich in:
-
Dark leafy greens (iron, folate)
-
Nuts and seeds (zinc, copper)
-
Eggs and dairy (B12, protein)
-
Berries and citrus fruits (vitamin C for antioxidant support)
Hydration is also essential; aim for at least 2–3 litres of water per day.
4. Reduce Stress Through Lifestyle Habits
Managing stress effectively can reduce the biological strain on your body and potentially slow down premature greying. Try incorporating:
-
Daily mindfulness or meditation
-
Regular physical activity
-
Proper sleep (7–8 hours)
-
Breathing exercises or yoga
Stress reduction benefits not only your hair, but also your overall well-being.
Common Myths About White Hair
Let's debunk a few popular misconceptions:
-
Plucking a white hair causes more to grow back: False. It may cause follicle damage, but it doesn’t multiply white hairs.
-
Only old people get white hair: False. Many people experience greying in their 20s and 30s.
-
Hair turns white overnight due to shock: Largely a myth, though extreme stress may accelerate visible greying over time.
Conclusion
So, what can turn your hair white? The causes range from genetics and ageing to stress, nutritional deficiencies, and oxidative damage. While you can’t stop time or change your DNA, you can make informed choices that slow the process and promote healthier hair.
Focus on:
-
Maintaining a nutrient-rich diet
-
Using herbal and clean hair care products
-
Managing stress through lifestyle practices
-
Protecting your scalp from environmental damage
By taking these simple but consistent steps, you can support melanin production, nourish your scalp, and enjoy stronger, healthier hair for longer.
