BETWEEN HAIRCUTS
Stray neck hair is the first thing to spoil a fresh cut. Here’s how to clean it up without wrecking your barber’s work.
A good haircut starts to look scruffy long before the hair on top needs cutting. The culprit is usually the back of your neck, where fine hairs grow back and blur the line your barber made. You can tidy it at home, as long as you know where to stop.
Why the Neckline Is Awkward
The back of your neck is out of view, so it’s hard to judge a straight line or an even finish.
Whether it’s rounded, squared or tapered, the shape was chosen when you were cut. Changing it yourself is risky.
One extra stroke upward and the line moves. You can’t put hair back, so it’s best to stay conservative.
The neck can get irritated if you press. Our neck shaving guide has more on keeping it comfortable.
Three Things to Get Right
Leave the shape your barber made and remove only the stray hairs that have grown below it. If you’re unsure where the line is, don’t guess; leave it.
Action: Tidy strays, don’t redraw the line.Use a hand mirror against your bathroom mirror, or take a quick photo of the back of your neck with your phone, so you can see what you’re doing.
Action: See the back before you shave it.Use short strokes downward from the line, with no pressure. Never drag the razor upward into the hairline.
Action: Down and light, never up.A Simple Neckline Routine
Set up a second mirror or take a photo so you can see the line and the stray hairs below it.
Wash with warm water and apply a little shaving cream or gel to the stray hair only.
Use short, light strokes downward from the line, rinsing the blade as you go.
Look again with your second view, rinse with cool water, pat dry and moisturise. If it feels sore, see our razor burn guide.

Frequently asked questions
There’s no fixed rule. Many men do it when stray hairs start to show, often once a week or so between cuts.
It’s safer to leave it. Ask your barber to show you where the line sits, or what they’d like you to leave, at your next cut.
Either can work. A razor gives a cleaner finish on stray hairs below the line, while a trimmer is gentler if you’re nervous.
Yes. Start with the £9.99 starter kit, which includes a premium handle. You can change, delay or cancel at any time for free.
A few light strokes below your barber’s line keep a haircut looking fresh for longer. See the back of your neck, go gently, and don’t chase a new shape.
