How to Cut Your Own Hair at Home

Cutting your own hair is a practical skill, not a bold act of confidence. With the right tools and a clear process, most people can maintain a buzz cut indefinitely at home, and keep medium-length hair neat between barber visits. The key is understanding that DIY cutting is about consistency and damage limitation, not replicating what a trained barber does in a single session. Start simple, go slower than you think you need to, and you'll rarely regret it.

What you'll need

• Clippers with a full guard set — #1 through at least #8. See the clipper guard sizes guide for length reference. Our best hair clippers picks cover what specs actually matter.
• Haircutting scissors — dedicated hair scissors with sharp, aligned blades. Regular household scissors crush and fray the hair shaft rather than cutting cleanly. See our best hair scissors guide for what to look for.
• Wide-tooth comb and sectioning clips — to keep sections in place as you work.
• Two mirrors — a wall mirror and a hand mirror to see the back.
• A trimmer — for neckline and ear edges. Many clipper sets include one; if not, buy separately.

Which guard should you start with?

Guard numbers follow the standard 1/8-inch steps used by most clipper brands. If you have never cut your own hair, start at least one number longer than you think you want — you can always go shorter, but each 1/8 inch (3mm) you take off by mistake takes about a week to grow back.

The full list, including half sizes and extended guards, is in the clipper guard sizes chart.

Step-by-step: the DIY haircut

1. Wash and dry your hair. Start with clean, completely dry hair. Wet hair clumps together and appears longer than it actually is, which leads to over-cutting. Wash it, towel-dry it, then let it air-dry or use a dryer before you pick up any tools.
2. Section the hair. For a clipper cut, clip the top out of the way if you want a different length on top than the sides. For a scissor trim, divide the hair into four working sections — front-left, front-right, back-left, back-right — held with clips. Working section by section prevents you from accidentally cutting across the grain.
3. Decide on your guard or scissor length. For clippers: choose your guard based on the look you want. A #4 (13mm) leaves a soft, brush-able finish; a #2 (6mm) is a classic tight clipper cut. When in doubt, start one guard longer than your target. For scissors: decide on a final length and cut your first section to establish it as a guide — all other sections will match this.
4. Work back to front with clippers, or front to back with scissors. With clippers, start at the nape and run the blades upward against the direction of hair growth in slow, overlapping passes. Go over each area twice from two directions to catch missed patches. With scissors, start at the front hairline, take a small section between your index and middle fingers, slide down to your guide length and cut, then pick up a little of the section you just cut with the next one so each piece matches. On short hair, lifting the hair straight up from the scalp keeps the top an even length; on longer hair, comb it down and trim only the ends.
5. Point-cut the ends for texture. After establishing length with scissors, the cut ends will look blunt and slightly blocky. Point-cut by angling the blades of your hair scissors to about 45 degrees and snipping upward into the tips — about a quarter-inch depth. This breaks up the hard edge and gives the hair natural movement without removing overall length.
6. Clean the neckline and around the ears. Switch to a trimmer with no guard for detailing. Outline the neckline in your chosen shape — squared (two vertical lines down from behind the ears joined by a horizontal line), rounded (following the natural neck curve), or tapered (feathering into the natural hairline). Edge carefully around each ear, using a comb held flat against the skin as a guide.
7. Tidy the sideburns. Comb the sideburns straight down and cut horizontally to your desired length. A common stopping point is around the middle of the ear, roughly level with the ear canal opening, but this is a style preference. Check both sides are level with each other in the mirror — an asymmetric sideburn is one of the most common and noticeable DIY errors.

Common mistakes to avoid

Cutting wet hair with scissors

Wet hair stretches and lies flatter, so it looks longer than it will be once dry — by up to an inch on straight hair and several inches on curly hair, which shrinks as it dries. If you cut to length while wet, it can end up much shorter than planned. Stick to dry cutting unless you're experienced.

Using the wrong scissors

Kitchen or craft scissors have blades that aren't aligned for hair's fine structure — they push the hair aside before cutting it, leading to split ends and a ragged finish. Invest in a dedicated pair of hair scissors. They don't need to be expensive, just sharp and purpose-made.

Rushing the back

The back of your head is the hardest part to see and the easiest to cut unevenly. Slow down here, check in the hand mirror after every section, and if you're not confident, leave the back at its current length and only trim the front and sides.

Skipping the neckline

An unclean neckline makes an otherwise decent DIY cut look unfinished. Even if the rest of the cut is imperfect, a clean neckline and neat ear outline read as intentional and tidy. Prioritise this step even if you rush the rest.

A simple clipper cut: shorter sides, longer top

If a single-length buzz feels too uniform, this is the next step up — no fade blending required:

1. Buzz the top with a longer guard (for example #4 or #5) front to back, against the grain.
2. Switch to a shorter guard for the sides and back (for example #2). Run it up from the sideburn and nape, stopping around the temple — roughly where your head starts to curve inward on top.
3. Blend the line between them with the guard in between (#3), using short upward flicks of the wrist at the transition rather than full passes.
4. Finish the neckline, ears and sideburns with the trimmer as in steps 6 and 7.

Once you can do this cleanly, a true fade uses the same idea with more steps and the clipper lever — see how to fade your own hair. For a one-length cut, the buzz cut guide covers the best guard for each look.

How often to cut your own hair

Hair grows about half an inch (1.25 cm) a month. On a #2 buzz, that doubles the length in about two weeks, so most people re-buzz every 1–2 weeks to keep it crisp. Shorter sides with a longer top look tidy for about 3–4 weeks, and a scissor trim on longer hair can wait 6–8 weeks. Tidying the neckline and around the ears between cuts stretches any of these. Our how often to get a haircut guide breaks this down by style.

When to go to a barber instead

DIY haircuts work well for maintenance: keeping a buzz tight, trimming split ends, or cleaning up a neckline between proper appointments. They are less reliable for the initial shape of a new style, advanced layering, or anything that requires seeing all angles simultaneously. If you want a specific new look — a clean fade, a precise fringe, or a shape that suits your face — get the first cut professionally, then maintain it yourself.
