Grey Hair at 22, 25, or 30 in Pakistan? Here's What's Causing It
Premature greying in Pakistani men and women in their 20s and early 30s is more common than the global average. Here's why — and what's worth actually fixing.
By The Hair Factory Team
If you noticed your first few greys before your 25th birthday and your father didn't go grey until his late 40s, something specific is happening — and it's worth figuring out. Premature greying among Pakistanis under 30 has been ticking up steadily for two decades. Surveys in Karachi and Lahore put the figure somewhere between 22% and 30% of urban under-30s reporting visible greys.
Some of this is genetic and not much can be done. Some of it is lifestyle and the changes are simple. This is the breakdown.
The genetic baseline
About 65% of premature greying cases come down to one thing — your family history. If both parents started greying before 35, you have roughly a 60-70% chance of doing the same. If one parent did, your risk is 30-40%. If neither did and you're greying at 25, look at the lifestyle factors below first.
Genetics determine when melanocytes start to slow down. Once they slow, no oil, no supplement, no shampoo restarts them. What you control is everything that pushes a borderline timeline earlier than it had to be.
Vitamin B12 deficiency
This is the single most actionable cause and the one most Pakistanis don't get tested for. B12 is critical for melanocyte function. Low B12 is linked to:
- Faster onset of greying
- Hair thinning, particularly at the crown
- Fatigue, brain fog, low mood
Urban Pakistani diets, even meat-eating ones, often run low on B12 because the preferred meat cuts (chicken breast, mutton chops) have less B12 than offal and oily fish. Vegetarian Pakistanis are at much higher risk.
A B12 blood test costs Rs. 800-1,500 at Chughtai, Excel, AKU labs. If you're under 250 pg/ml, talk to a GP about supplementation.
Iron and ferritin
Iron deficiency is the second-most-common Pakistani nutritional gap and it correlates with greying. Pakistani women between 18 and 35 have especially high rates of low ferritin because of periods plus low-iron diet patterns. The greying connection isn't as direct as B12 but it's documented.
Test cost is similar. Treatment is dietary first (red meat, dates, jaggery, spinach) and oral iron only if levels are clinically low.
Smoking
Smokers are 2 to 4 times more likely to grey before 30 than non-smokers. The mechanism is oxidative stress damaging melanocytes faster than they can recover. If you smoke and you're greying early, this is causal and the only fix is stopping.
Vaping appears to carry roughly the same risk based on the limited evidence so far. Hookah/sheesha is worse on a per-session basis than cigarettes because of the longer exposure time.
Stress, but in a specific way
Day-to-day annoying stress doesn't cause greying in any measurable way. What does cause it is sustained chronic stress over years (working 70-hour weeks, ongoing family conflict, long unemployment) — and especially acute traumatic events. The biological mechanism is real and was confirmed in a 2020 Harvard study — adrenaline triggers melanocyte stem cell depletion.
The fix isn't "relax more" (useless advice) — it's making structural changes that reduce sustained cortisol exposure. 7+ hours of sleep is the single biggest lever.
Things that DON'T cause greying
Despite widespread Pakistani belief, none of these have evidence behind them:
- Wearing topis or caps in summer (scalp warmth doesn't affect melanocytes)
- Plucking a grey hair causes "more to grow" (the follicle next to it isn't connected)
- Washing hair daily (frequency doesn't accelerate greying)
- Cold-water rinses or hot-water rinses (no effect on greying mechanism)
- Specific shampoos (sulphates etc.) accelerating greying
These are folklore. Don't waste mental energy on them.
Should you do anything about it
That's actually a personal call. Some Pakistani men wear early greys with confidence — the "salt and pepper" look at 28 reads as distinguished if the rest of the grooming is sharp. Some find it ages them visually by 5-7 years and want it gone. Neither is wrong.
If you want coverage that doesn't damage hair and doesn't commit you to a salon every 3 weeks, a hair colour shampoo is the right tool. Read our breakdown of [hair colour shampoo vs traditional dye](/blog/hair-color-shampoo-vs-traditional-dye) before deciding.
The actual takeaway
If you're under 30 and greying:
- Get B12 and ferritin tested once (Rs. 1,500-2,500 total)
- Quit smoking if you smoke
- Sleep 7+ hours
- Accept the genetic part you can't change
- Cover what's there if it bothers you, with a formula that won't make it worse
Realistic expectations save a lot of time and money compared to chasing miracle cures.
Questions Our Customers Ask
I'm 24 and have 10-15 visible greys. Is that normal in Pakistan?
It's not unusual. About 1 in 5 Pakistani men report first greys before age 25. If your father greyed early too, it's mostly genetics. Worth getting a B12 test once just to rule out a deficiency.
Can stress at university cause grey hair?
Day-to-day exam stress, no. Sustained 18-month or longer chronic stress can accelerate greying by 5-15%. The fix is structural (sleep, exercise) not 'try to relax'.
Should I cover greys at 25 or wear them?
Personal choice. If it dents your confidence socially or professionally, covering is fine and easy with a 15-minute hair colour shampoo every 2-3 weeks. If you wear it with confidence, also fine.
