classic one-length haircut is one of the fundamental techniques in hairdressing. It creates a clean, blunt look with no layers, making it perfect for clients who want a sleek, polished finish. This technique requires precision, control, and proper sectioning to ensure even results.

Tools You’ll Need:

️ Professional hair shears (preferably convex edge shears for precision)
️ Cutting comb
️ Sectioning clips
️ Water spray bottle
️ Cutting cape
️ Mirror


Step 1: Prepare the Hair

1️ Drape the client with a cutting cape and ensure they are seated upright with their head in a neutral position.
2️
Shampoo and condition the hair if necessary, then towel dry. The one-length cut is best done on damp hair for precision.
3️
Comb through the hair to remove any tangles and ensure the natural fall of the hair is even.


Step 2: Section the Hair

1️ Create a center parting from the forehead to the nape.
2️
Separate the hair into four sections:

  • Two front sections from the ear forward.
  • Two back sections, divided with a horizontal parting at the occipital bone.
    3️
    Clip up the top sections to keep them out of the way while working on the lower sections.

💡 Pro Tip: Always check for natural growth patterns or cowlicks before cutting.


Step 3: Establish the Baseline

1️ Start with the bottom back section (nape area).
2️
Comb the hair down and hold it with minimal tension to maintain the natural fall.
3️
Decide on the desired length and make the first cut.
4️
Use the comb as a guide to ensure an even cut.
5️
Continue cutting across the nape in a straight horizontal line.

💡 Pro Tip: Keep your shears parallel to the floor and cut in one smooth motion for the cleanest result.


Step 4: Work Your Way Up

1️ Release the next section and comb it down over the baseline.
2️
Use the previously cut hair as a guide and carefully trim the new section to match.
3️
Repeat this process, working section by section up the head.
4️
Check both sides frequently in the mirror to ensure symmetry and balance.

💡 Pro Tip: Keep your cutting hand steady and avoid lifting the hair—this can create unwanted layers.


Step 5: Cut the Front Sections

1️ Release the front sections and comb them down naturally.
2️
Use the back length as a guide and cut the front sections to match.
3️
If the client wants a blunt bob look, make sure the sides are even.
4️
Check both sides by bringing them together under the chin.

💡 Pro Tip: Keep the head in a neutral position—if the client tilts their head down, the result may be shorter than expected.


Step 6: Check for Balance & Final Touches

1️ Comb the hair down and check for any uneven areas.
2️
Make small refinements as needed, ensuring both sides are perfectly even.
3️
Dry the hair and do a final check, making micro-adjustments if necessary.

The result: A perfectly polished one-length cut with a blunt, even finish.


Final Tips for a Perfect One-Length Cut

️ Always cut with precision and avoid tension when holding the hair.
️ Use sharp, high-quality shears (preferably Japanese convex shears for a crisp cut).
️ Keep checking for symmetry and balance throughout the process.
️ Maintain a steady hand and avoid overcutting—you can always trim more, but you can’t add length back!


A classic one-length cut is the foundation for many hairstyles, including bobs, long sleek cuts, and polished blunt styles. Mastering this technique will elevate your precision cutting skills and ensure a flawless, professional finish every time!
