Grey Hair in Young Men: Causes and Options

Grey hair in young men is mostly inherited. Each follicle has its own pigment cells, and when they run out that hair grows back without colour, so if your dad or grandad went grey at 30 there is a fair chance you will too. Dermatologists call it premature before 20 for white Europeans, 25 for Asians and 30 for men of African descent. A couple of medical causes are worth ruling out with a blood test. Nothing about your shampoo or your haircut caused it, and nothing on a shelf reverses it.

Why it happens early

Start with your family. A 2017 study of patients with premature greying, published in the Indian Journal of Dermatology, found that nine in ten of them had a parent or sibling who had gone grey early too. That is one study, but every dermatology source we read puts inheritance first.

The pigment comes from cells called melanocytes, which live in the follicle and feed colour into the hair as it grows. As they slow down, the hair comes through lighter. When they stop, it comes through white. A head that looks grey is really a mix of fully coloured hairs and white ones side by side, and that is why it creeps in rather than arriving all at once.

Then there are the medical links. Low vitamin B12 and an underactive thyroid both turn up in the research alongside early greying. Smoking is linked in studies too. We are barbers, so this is where we stop: if the grey has come on fast, or you just want to know, see a GP. A blood test answers it, and that is about your health, not your hair.

Stress, plucking and the other things men tell us

Stress. Everyone has seen the headline. It comes from a Harvard study published in Nature in January 2020, and it was done on mice. Under acute stress, the nerves around the follicle used up the mice's pigment stem cells, and the fur went white. That is a real result about mice. It is not proof that your manager greyed your temples, and nobody should promise you that a calmer year will bring the colour back.

Plucking. The idea that pulling one grey hair makes two grow is a myth. Each follicle works on its own and cannot tell its neighbours anything. The one you pulled grows back grey, and the rest of your head carries on as it was going to anyway. Plucking still does harm, though. Pull the same follicle often enough, for long enough, and it can scar and stop producing hair at all. So you swap a grey hair for a gap.

Cutting it. Clippers do not make anything grow back grey. You notice the grey after a short cut because it is on show, not because the cut made it.

What a cut can do for grey hair in young men

This is the useful bit, and it depends on one question we will ask you: should the grey disappear, or should it look like you meant it?

To make it less noticeable, go shorter at the sides. On the men we cut, early grey usually shows at the temples and above the ears first, and that is exactly where a fade or a taper takes the hair down to almost nothing. At a grade 1 or below there is barely any hair left to be grey, so most of it goes. A taper fade (£17, 40 minutes) leaves a short stubble of hair low down, so the grey you still have blends in rather than standing out against bare skin.

To make it look deliberate, go shorter all over. A few white hairs in a head of dark length stand out on their own. Take the whole head to a short even grade and the same hair reads as one salt and pepper colour instead of a scattering. The point about hair against skin in our buzz cut lengths post applies here. A grade 2 on mixed grey hair looks softer than the same grade on jet black, which is often what a man going grey wants anyway.

What not to do is keep the sides long and the top short. That puts the most grey in the most hair, right where people look first.

Beards are their own case. A beard can go grey at a different pace from the head, and it tends to go in patches rather than evenly. Long, a grey patch looks like a stain. Trimmed short and even it reads as texture. Adding a beard trim to a haircut takes the bill to £24, or the trim is £11 booked on its own.

If you want to colour it

We do not colour hair at Golden Scissors. We can cut around grey, but we cannot get rid of it. If you are going to colour at home, know two things first.

Grey hair holds dye differently. It is more porous, so a semi-permanent colour that is meant to fade in a few weeks can stay much longer than the box says. Our post on what "temporary" colour actually does explains why the same product lasts different lengths on different heads.

On short hair, roots show fast. There is no length to hide a grey line at the parting, and every trim takes off the coloured ends and leaves the new growth. Dark dye on short grey hair grows out as a flat block of colour sitting on a band of grey, and that line is harder to live with than the grey was. Do the skin test the box tells you to do, every time, even with a brand you have used before.

Hide it or show it

Tell us which way you want the grey to go. Hide it or show it is all we need to hear, and it changes the clipper we pick up first. If you are not sure yet, say that too. We would rather go a grade longer at the temples and see how it looks in a month than take it all off and leave you wishing you had waited.

If the grey has come with a hairline that is moving as well, that is a separate question with its own answers, and hair loss in your twenties is where we go through it. Otherwise, book a chair, point at the bits that bother you, and we will cut around them.
