How to cut your own hair
Seven steps. The order is the whole guide, and the two-numbers-longer rule is the one that saves the fortnight.

The seven steps
- Cut dry, on clean hair, in a room you can sweep. Wet hair sits shorter than dry hair, so a wet cut ends up longer than intended once it dries. Clippers also clog on wet hair. Dry, clean and combed out is the only correct starting state.
- Set up two mirrors before you switch anything on. A bathroom mirror plus a hand mirror, angled so you can see the back. This is the real limiting factor in cutting your own hair, and sorting it out afterwards is too late.
- Start two guard numbers longer than you want. Cut the whole head at that length first. Look at it. Then go down one number if you still want shorter. You cannot put hair back and it grows about half an inch a month.
- Do the sides and back first, against the grain. Work upward in overlapping strokes, against the direction of growth, keeping the guard flat against the skull. Overlap each pass by about half the guard width so nothing is missed.
- Blend the transition with the taper lever, not a different guard. Where the short sides meet the longer top, open the taper lever gradually across several passes and flick the clipper away from the head at the top of each stroke. A guard change here leaves a visible step.
- Do the top last, with a longer guard or scissors over a comb. The top is where a mistake is most visible and hardest to hide, so it goes last when your hand has warmed up. Lift the hair with a comb and cut what stands proud of it.
- Set the neckline and around the ears with the guard off. Guard off, clipper inverted, working downward. Follow the natural hairline rather than cutting a straight line across it - a squared-off neckline grows out badly and looks worse every day for a fortnight.

Why the order is the guide
Sides and back first, top last, neckline at the very end. That sequence is not arbitrary and getting it wrong is the most common way a home haircut goes badly.
The sides are the forgiving part: uniform length, easy to see, easy to fix by going shorter. Doing them first warms your hand up on the least consequential area. The top is where a mistake is most visible and least fixable, so it goes last. And the neckline goes at the very end because it is drawn relative to a finished cut - set it first and it will be in the wrong place once the length above it changes.
The mirror problem, which is the real problem
People assume the hard part of cutting your own hair is the cutting. It is not. It is that you cannot see a third of your own head, and the third you cannot see is the third other people look at most.
- Hand mirror plus wall mirror, angled so the back appears in the wall mirror. Set this up before you start, not when you get there.
- Or a phone on a stand with the front camera running, which is easier to angle and shows you a live view rather than a reflection of a reflection.
- Or accept a simpler cut. A single-length buzz needs no blending and is nearly impossible to get wrong. That is a legitimate answer rather than a compromise.
The technique, in three rules
Against the grain. Move the clipper against the direction the hair grows. Going with it lays the hair down ahead of the blade and the clipper skims over it, which is what produces patchy results people blame on the tool.
Guard flat to the skull. Tilting the guard away from the head leaves the hair longer than the number says. This is how one side ends up longer than the other - your wrist angle differs between your dominant and non-dominant hand and you will not notice.
Overlap by half. Each pass should cover half the width of the previous one. Butting passes edge to edge leaves thin stripes of uncut hair that only show up in daylight, several hours later.
Blending, if the sides and top are different lengths
Use the taper lever, not a different guard. Opening the lever gradually across several overlapping passes produces a continuous change; switching guards produces a step. Flick the clipper away from the head at the top of each stroke so the pass ends softly rather than in a line.
If you want a proper fade rather than a soft transition, that is a different job and a different tool question - the fading roundup covers what actually matters, which is the lever rather than the guards.
Afterwards
Brush the cut hair off before you shower, or you will be picking it out of a drain for a week. Then clean and oil the clipper while you remember - fifteen seconds that roughly doubles how long the blade stays sharp.
And if you want the cut to hold a shape rather than just be short, the styling comparison covers the three products that behave differently and why the ingredient list tells you which is which.
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 pickA first home haircut
Wahl Color Pro (79300)
Corded, self-sharpening precision blades, an adjustable taper lever, and guards that are color-coded to their length with a matching guide printed on the clipper body. That last detail is the entire pitch and it is a better one than it sounds: the most common home-haircut disaster is reaching for the wrong guard.

The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Color-coded guards with the code printed on the clipper - the cheapest possible defense against grabbing the wrong one
- Self-sharpening precision blades, published by Wahl
- Corded, so there is no battery to manage or degrade
- Adjustable taper lever included even at this level
Flaws
- Corded only - you are working around a cable behind your own head
- Wahl does not publish a motor rating, runtime or warranty for it
- Kit contents vary between the 79300 variants, so check the listing rather than the model number
The working behind the 5.3
- 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: 9.0
- Color-coded guards remove the single most common home-haircut error (++), corded so the battery is never the problem (+), but Wahl publishes almost nothing about it - no motor, no runtime, no warranty (--).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 0.0
- 0 of 5 specifications a buyer would expect are published: . Not published: runtimeMin, chargeMin, settings, material, warrantyLabel. 0 / 5 x 10 = 0.0.
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 Wahl Color Pro 79300 published specifications.
2Fading and blending at home
Wahl 5 Star Magic Clip (8148)
Cord or cordless with a published 90-minute lithium runtime and zero-overlap 2161 blades, plus a taper lever you can work with your thumb mid-stroke. The taper lever is the whole reason this is the fade pick: it changes cutting length continuously rather than in guard-sized jumps, which is what a blend actually needs.

The arithmetic: 260 uses a year x 5 years of assumed service life = 1300 uses.
What it gets right
- Published 90-minute lithium runtime, and it runs corded when flat
- Zero-overlap 2161 blades with a thumb-operated taper lever for continuous length change
- Eight attachment combs, oil and cleaning brush in the box
- Cord-or-cordless, so a dead battery never ends a haircut halfway
Flaws
- A taper lever rewards practice; on a first attempt it is one more thing to get wrong
- Wahl does not publish a motor rating for it, so it cannot be compared numerically to the corded Andis
- No published charge time
The working behind the 5.9
- 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: 8.0
- Cord-or-cordless removes the flat-battery failure entirely (++), 90 minutes published (+), eight combs is a sane number (+), but a taper lever is a skill and a first-time home barber has enough of those already (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 4.0
- 2 of 5 specifications a buyer would expect are published: runtimeMin, settings. Not published: chargeMin, material, warrantyLabel. 2 / 5 x 10 = 4.0.

3Not tearing hair while you tidy
Kent 81T Beard and Mustache Comb
73 mm, sawcut from cellulose acetate and hand-sanded in England. Sawcut matters more than it sounds: a molded comb has a seam along every tooth that catches and splits hair, and a sawcut one does not. On a beard, split ends are most of what scratchiness actually is.

The arithmetic: 260 shaves a year x 5 years of assumed service life = 1300 shaves.
What it gets right
- Sawcut and hand-sanded, so there is no molding seam to split hair
- 73 mm - pocket-sized, which is the size you will actually carry
- Cellulose acetate rather than injection-molded plastic
- Made in England by a firm that has done nothing else for two centuries
Flaws
- Costs several times an ordinary drugstore comb that looks identical
- 73 mm is too small to be useful on a long beard's full length
- Kent publishes tooth spacing nowhere
The working behind the 9.2
- 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: 9.5
- Sawcut teeth with no molding seam is a real, checkable construction difference that prevents split ends (++), pocket-sized (+), but tooth spacing is unpublished and it costs many times a visually identical drugstore comb (-).
- Refill economics: 8.0
- Nothing to refill. The only future cost is replacing the item itself.
- What the maker publishes: 10.0
- 2 of 2 specifications a buyer would expect are published: material, madeIn. 2 / 2 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 Kent handmade sawcut comb published construction.

Questions people actually ask
What guard should I use to cut my own hair?
Start two numbers longer than the length you want. On the traditional clipper scale a #4 is about 12.5 mm and a #2 about 6 mm, so if you are aiming for a #2 finish, cut the whole head at a #4 first and look at it. The full mapping is here.
How do I cut the back of my own head?
Two mirrors, and by feel more than by sight. Set the hand mirror so you can see the back in the bathroom mirror, then work in short overlapping passes and check constantly. This is the genuinely hard part and it is worth accepting a simpler cut because of it.
Should I cut my hair wet or dry?
Dry, always, with clippers. Wet hair sits shorter and straighter than dry hair, so a cut that looks right wet is longer and uneven once it dries. Wet hair also clogs a clipper blade.
Where should the neckline go?
Follow your natural hairline rather than cutting a straight line across it. A squared-off neckline looks sharp for three days and then looks progressively worse for a fortnight as it grows into the shaved area below it.
How often will I need to do this?
Every two to four weeks for a short cut. That frequency is the actual argument for owning a clipper: on our assumed five-year service life it is a one-off purchase against a recurring appointment.
