The first few show up somewhere obvious. A temple, a parting, right at the front. Five or six strands, catching the light, and the fastest thing in the world is to reach up and pull them out.
It works, too — for a few weeks. Then they come back, because pulling a hair out does nothing to the follicle that made it. What it does do is worth understanding before it becomes a habit, and the reason is not the one most articles give you.
First, the Myth: No, Two Don't Grow Back
Let's clear this one up, because it is the reason a lot of people stop plucking and it isn't true.
Pulling out a grey hair does not create more grey hairs. One follicle produces one hair at a time, and plucking it has no effect on the follicles around it. The hair that grows back will be grey again — it was always going to be — but it will be one hair, not two.
We would rather tell you that than let a myth do the work. The real reason to stop is more specific, and you can see it under a microscope.
Hair Growth Phases Explained
Hair naturally cycles through three distinct phases[1]:
- Anagen (active growth): the hair is actively growing, deeply rooted, and firmly attached. This phase lasts two to six years — longer for some people.
- Catagen (transition): growth slows, the follicle shrinks, and the hair prepares to enter its resting phase. Catagen roots become elongated and taper toward the end, enclosed by a transparent root sheath.
- Telogen (rest): the hair is no longer growing, and the root takes on a distinctive club shape. This hair is ready to fall out on its own.
Recognizing Different Hair Roots
You can tell which phase a hair was in by looking at its root — and the difference is visible even without a microscope once you know what to look for. The photographs below are our own, taken through the microscope in our lab.
Anagen and catagen roots are elongated and slender, wrapped in a clear sheath. That sheath is follicle tissue that came out with the hair.

Telogen roots are club-shaped, with no sheath at all. These hairs were finished and ready to go.

The hairs that come out on your brush are almost always telogen hairs. Club-shaped, no sheath, shed on schedule. That is your hair cycling normally, and it is nothing to worry about.
Now pull one out on purpose and look at the root. It has a sheath on it. That hair was not finished — it was in anagen or catagen, still attached, still being built.

Why Pulling Matters
Around 85–90% of the hair on your scalp is in anagen at any moment. Only 10–15% is in telogen — the phase where a hair is genuinely ready to leave.
So when you pull ten hairs, roughly nine of them were not finished. Each of those was interrupted mid-cycle: the follicle is forced out of its growth phase early and has to restart.
Once is not a problem. Your follicle will produce a new hair, and the odds are strongly in favour of it looking exactly like the one before it. The issue is that nobody plucks a grey hair once. You pluck the same few spots, every few weeks, for years — and repeated trauma to the same follicles is a different proposition from a single pull. Over time it can shorten the growth phase, thin the hair produced, and in cases of long-term chronic plucking, stop production from that follicle for good.
And there is a plainer cost before you ever get there. The places people pluck are the places that show — the hairline, the parting, the temples. Thinning there reads as ageing far more clearly than a few grey strands ever did.
Why This Matters Most in Your Thirties and Forties
Here is the part that is easy to miss when you are only dealing with five or six strands.
A hair on your scalp grows for two to six years before it sheds. The hair you have today is the hair you will still be looking at several years from now — and everything done to it in that time is still there, because the hair shaft is dead tissue with no capacity to repair itself.
Which means the decisions you make at the first sign of grey are not really about this year. They are about what your hair looks like at the end of its current cycle.
Grey coverage is not a one-time treatment. Start at thirty-five with a handful of strands and you are signing up for ten or more applications a year, on hair that stays on your head for years at a time. By the time greys are a real presence, that same length has been through thirty or forty rounds of whatever you chose at the start.
A Better Alternative: Blend Them Instead
The awkward thing about early grey is the proportion. Five per cent of your hair has changed, and a permanent chemical colour treats one hundred per cent of it to deal with that — lifting pigment out of every strand, including the ninety-five that were fine.
Plant colour goes the other way. Pigment is carried in by water and layers over what is already there, so nothing has to be stripped for it to work. On grey it blends rather than blocking out, which at this stage is exactly what you want: the greys drop back into the surrounding tone instead of turning into a flat, uniform panel that announces itself when roots come through.
It asks for more time — about an hour on the hair, and two to three days to finish developing — and it cannot lighten hair, since lightening requires bleaching. It is also not a treatment and won't repair damage that is already there. What it does is leave the cuticle you have alone, so that the shine you were born with is still around when the greys stop being a handful.
What To Do Instead
- Cut, don't pull. Snip a stray grey at the root with small scissors if it bothers you. Same result visually, no follicle involved.
- Blend early rather than covering late. A few greys are the easiest stage to work with, not the hardest.
- Think about the total, not the appointment. Whatever you choose now, you are choosing it thirty times over the life of the hair on your head today.
Those first silver strands are not the enemy. They are evidence you still have plenty of hair to work with — and keeping it that way is a longer game than any single application.
