How to shave your neck
Nearly everybody who says shaving irritates their skin means their neck. It is a different surface from a cheek and it needs a different method.

The short version
Map the grain on your neck separately - it is usually not downward - shave the neck last, keep the skin pulled tight, and take the second pass across the grain rather than against it. The neck is where nearly all shaving irritation happens because it has three problems a cheek does not: changing growth directions, loose skin, and a shelf under the jaw. Accepting slightly less closeness here is the whole fix.

Why the neck is a different problem
When somebody says shaving irritates their skin, they almost always mean a band running from the jaw to the collar. The cheeks are fine. Understanding why is most of the fix.
- The grain changes within a few centimeters. A cheek has one direction. A neck commonly has three - upward at the bottom, sideways in the middle, and a swirl under the jaw. Shaving all of it downward means shaving much of it against the grain without intending to.
- The skin is loose and thin. It moves under the blade rather than presenting a flat surface, so the razor rides over hair, misses it, and you go back over the same skin a third and fourth time.
- There is a shelf. The jawline is a hard edge with a hollow behind it, and a flat razor head cannot follow that transition without the angle changing mid-stroke.
Mapping it, once, properly
Do this on two days of growth, dry, with a flat hand. Push in each direction across each area of the neck and note where it feels rough - rough means you are going against the grain.
| Area | Common growth direction | So the first pass is |
|---|---|---|
| Under the chin | Downward or in a swirl | Downward, short strokes |
| Mid neck, either side | Sideways toward the center | Sideways, outward to inward |
| Low neck above the collar | Upward | Upward, from the collarbone |
| Adam's apple | Variable, often upward | Upward, with the skin pulled to one side |
Write it down the first time. Growth direction does not change over your life, so this is a ten-minute investment you make once.
The pass structure
- First pass, with the grain - following your map rather than gravity. This removes most of the length and does most of the work.
- Re-lather completely. Not a smear over the residue. A full second lather, which takes ten seconds and prevents most of what people call razor burn.
- Second pass, across the grain - at roughly ninety degrees to the growth direction, not opposite it. On a neck this is the single most useful adjustment available.
- Stop. No third pass on the neck. The remaining stubble you can feel but not see is not worth what a third pass costs.
Stretching, which is half the technique
Every stroke on a neck should be on skin that somebody is holding tight. Tilt the head back and away from the side you are shaving, then use your free hand to pull the skin in the opposite direction to the stroke.
This does two things: it flattens the surface so the razor makes one clean pass instead of three ineffective ones, and it stands the hair more upright so it is cut rather than pushed over. If you fix nothing else from this page, fix this.
Afterwards
Cool rinse, alum block, then an alcohol-free balm. The alum tells you where you pressed - a stinging stripe along one side of the neck is a technique map, not a product failure.
Skip alcohol-based splashes on the neck entirely. This is the thinnest facial skin you have and it is the area you just worked hardest - the aftershave roundup covers the balms, and the balm-versus-moisturizer question is a separate page.
If bumps still appear a day or two later, that is ingrown hairs rather than razor burn and it means the second pass is still going too close. Drop the across-the-grain pass for two weeks and see whether the neck clears.
Every pick, with the working
Each entry shows the published specifications, the axis scores they produce and what you give up. The order is the computed order, not a commercial one, and the arithmetic is open underneath every score.
Our pickOne razor, no research
Merkur 34C HD
Buy this one if you want to stop reading and start shaving. It is 68 grams of chrome-plated brass on a short knurled handle, which is heavy enough that you naturally stop pressing, and the head is a plain closed comb with nothing to set, adjust or get wrong. It has been in production in Solingen for decades, so parts, advice and blades are everywhere.
- Weight
- 68 g
- Length
- 80 mm
- Material
- Chrome-plated brass

- Blade gap
- Not published
- Blades in the box
- 0
- Made in
- Germany
- Refill
- Universal standard
- Warranty
- Not published
- Assumed service life
- 5,200 uses
The arithmetic: 260 shaves a year x 20 years of assumed service life = 5200 shaves.
What it gets right
- 68 g in a 80 mm body: the weight does the work, which is exactly the habit a cartridge user has to unlearn
- Closed comb with no adjustment, so there is one variable fewer on your first month
- Two-piece construction; the head unscrews as a unit and there is nothing to lose in the sink
- Takes any standard double-edge blade, so the refill is a commodity
Flaws
- The 80 mm handle is short for large hands, and Merkur's own longer handles are a separate purchase
- No blade in the box, so the first order needs a blade pack alongside it
- Chrome over brass will show wear at the edges over years in a way stainless will not
The working behind the 8.9
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.5
- Closed comb (+), no adjustment to set (+), 68 g published weight in the range where the razor's own mass supplies the pressure (+), no blade included so the first order is two items (-).
- Refill economics: 10.0
- The refill is a commodity standard that dozens of factories make, so the price is set by competition and no single maker can raise it.
- What the maker publishes: 8.6
- 6 of 7 specifications a buyer would expect are published: weightG, lengthMm, material, madeIn, headType, bladesIncluded. Not published: bladeGapNote. 6 / 7 x 10 = 8.6.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Merkur 34C HD listed specifications (Fendrihan).
2The lightest touch, machined to spec
Henson AL13 Medium
Henson's argument is that razor burn is an engineering problem, and it publishes the tolerances to back it: blade angle fixed at 30 degrees, machined to as tight as 12.7 micrometers at an aerospace facility in Ontario. At 37 grams it is by far the lightest razor here, which inverts the usual advice — you cannot let this one do the work, you have to let it float.
- Weight

- Refill
- Universal standard
- Warranty
- Not published
- Assumed service life
- 5,200 uses
The arithmetic: 260 shaves a year x 20 years of assumed service life = 5200 shaves.
What it gets right
- Published machining tolerance of 12.7 micrometers and a fixed 30-degree blade angle, which nobody else in this ledger discloses
- 37 g aluminum body with a Type II anodized finish; nothing to chip or peel
- Five blades in the box
- Sold in Mild, Medium and Aggressive so the choice is made once, at purchase, rather than every morning
Flaws
- 37 g is very light, which removes the weight cue a cartridge user relies on
- The exposure level is fixed at purchase; changing your mind means another razor
- Aluminum will not feel like the heirloom object a stainless razor does
The working behind the 8.5
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 7.5
- Fixed geometry with a published 30-degree blade angle removes the angle guesswork (+), blades included (+), but 37 g is the lightest here and the razor's own mass supplies almost none of the pressure (-).
- Refill economics: 10.0
- The refill is a commodity standard that dozens of factories make, so the price is set by competition and no single maker can raise it.
- What the maker publishes: 8.6
- 6 of 7 specifications a buyer would expect are published: weightG, material, madeIn, headType, bladeGapNote, bladesIncluded. Not published: lengthMm. 6 / 7 x 10 = 8.6.

3Closing weepers and telling you what your technique did
Osma Alum Block 75 g
A 75 gram brick of 100 per cent potassium alum, wetted and wiped over the face after the shave. It is astringent and hemostatic, so it closes the pinprick weepers a new safety razor user produces. Its real value is diagnostic: the amount it stings is a direct readout of how much you pressed, and no other product on this site gives feedback that immediate.
- Net weight

- Fragrance
- Fragrance-free

Published key ingredients: Potassium alum (100%).
What it gets right
- One published ingredient: 100 per cent potassium alum. There is nothing else in it
- Osma publishes the block dimensions (58 x 37 mm) and the weight
- Stings in proportion to the irritation you caused, which is the fastest technique feedback available
- Osma publishes an approximate one-year service life under normal use
Flaws
- It stings, and on a bad shave it stings a lot
- Drying: it needs a balm or moisturizer after it, so it is never the last step
- Must be dried and stored dry or the block dissolves at the edges
The working behind the 7.5
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 7.0
- A single published ingredient with no formulation to evaluate (++), published weight, dimensions and service life (+), immediate technique feedback (+), but it stings (-) and it is drying enough to require a second product after it (-).
- Refill economics: 8.0
- Nothing to refill. The only future cost is replacing the item itself.
- What the maker publishes: 8.0
- 4 of 5 specifications a buyer would expect are published: netWeightG, keyIngredients, fragranceFree, madeIn. Not published: volumeMl. 4 / 5 x 10 = 8.0.

4Every face, on day one
Nivea Men Sensitive Post Shave Balm
100 ml, alcohol-free, with chamomile extract, witch hazel, vitamin E and pro-vitamin B5 on a fully published ingredient list. The single most useful change most men can make to their shave is to stop putting alcohol on a freshly abraded face, and this is the cheapest way to do it.
- Volume
- 100 ml
- Fragrance
- Fragranced
- Refill
- Nothing to refill
- Warranty
- Not applicable
- How long it lasts
- 50 uses
Published key ingredients: Chamomile flower extract, Witch hazel extract, Tocopheryl acetate (vitamin E), Panthenol.
The arithmetic: 100 ml / 2 ml per application (assumed) = about 50 applications.
What it gets right
- Alcohol-free — the one property that actually matters immediately after a blade
- 100 ml with a complete published ingredient list
- Chamomile, witch hazel, vitamin E and pro-vitamin B5
- Sold everywhere, at a price that makes it a default rather than a decision
Flaws
- Contains fragrance, so not for a genuinely fragrance-intolerant face
- Light enough that dry skin will want a moisturizer over the top in winter
The working behind the 8.4
- How long it lasts: 5.8
- 100 ml / 2 ml per application (assumed) = about 50 applications. At five shaves a week, that is about 2.3 months. A 4-month supply scores 10 in this category, so 2.3 / 4 x 10 = 5.8.
- Ease of switching: 9.5
- Alcohol-free, which is the property that decides whether a post-shave helps or hurts (++), 100 ml with a published ingredient list (+), contains fragrance (-).
- Refill economics: 8.0
- Nothing to refill. The only future cost is replacing the item itself.
- What the maker publishes: 10.0
- 3 of 3 specifications a buyer would expect are published: volumeMl, keyIngredients, fragranceFree. 3 / 3 x 10 = 10.0.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Nivea Men Sensitive Post Shave Balm published ingredients.

Questions people actually ask
Why does my neck get irritated but not my face?
Three reasons at once. Neck skin is thinner, the hair often grows in several directions within a few centimeters, and the skin is loose so it moves under the blade. All three mean more passes over the same skin, which is what irritation actually is.
Which direction does neck hair grow?
Rarely straight down, which is the assumption that causes the problem. Common patterns are upward from the collarbone, sideways toward the center, and a swirl just below the jaw. Map yours once by feel and the direction stays the same for life.
Should I shave against the grain on my neck?
No. This is the one place where the closeness is genuinely not worth it - the neck is where razor bumps appear and it is where they take longest to clear. The razor bump page covers why a closer shave makes bumps worse rather than better.
How do I shave under the jaw?
Tilt your head back to stretch the skin over the jawline, then shave up from under the chin toward the jaw rather than down over it. Trying to shave down across the jaw shelf is how people catch the edge on the bone line.
Is a lighter or heavier razor better for the neck?
Neither reliably, but a razor with a published low blade exposure helps - Henson publishes an exposure figure and a machining tolerance, which is unusual. The sensitive skin roundup ranks on exactly that.
