The short answer
Threading removes hair from the root using a twisted cotton strand rolled across the skin. The twist acts as a mechanical trap — catching hairs between the loops and pulling them cleanly from the follicle. No heat, no chemicals, no residue. Results last two to four weeks, similar to waxing and sugaring, because hair is removed at the root rather than cut at the surface.
The method has a real technique learning curve. Most people need ten to twenty minutes of practice on a low-stakes area before the thread starts gripping reliably. Once the motion is learned, it is one of the most precise root-removal options available at home — capable of removing individual hairs with accuracy that wax cannot match.
What you need
A single strand of cotton thread — standard sewing thread works; dedicated threading thread is available from beauty suppliers. Synthetic thread (polyester) is not suitable: it lacks the texture to grip the hair shaft effectively.
Thread length: 40 to 50 centimetres, tied at the ends to form a loop. A longer loop gives more working room; a shorter loop gives more tension control. Experiment to find what works for your hand span.
No other products are required. Clean, dry skin is the one preparation non-negotiable — any oil, moisturiser, or lotion on the surface reduces the thread's grip on the hair shaft.
Before you start: prep
Cleanse and dry. Wash the area with a gentle cleanser and pat dry. If your skin tends to produce oil, a light application of translucent powder over the treatment area helps the thread maintain grip.
No actives or retinoids. Per AAD guidance on hair removal, avoid applying retinoids, strong AHAs, or BHAs to the treatment area for 24 to 48 hours before threading. These thin the skin surface and increase sensitivity to the mechanical pull of the thread.
No broken skin or active breakouts. Threading is not suitable for areas with active acne, open wounds, sunburn, or inflamed skin. The mechanical action of the thread can spread bacteria from open breakouts and worsen inflammation.
Lighting and mirror. Particularly for eyebrows and upper lip, good lighting and a magnifying mirror significantly improve accuracy. Threading is a precision technique — the visual feedback matters.
Step-by-step: the threading technique
1. Form the loop and create the twist. Cut 40–50 cm of cotton thread and knot the ends together to form a closed loop. Hold the loop between both hands, with three or four fingers of each hand inside the loop. Wind one end of the loop six to eight times — this creates the twisted centre section that does the work. You should see a clear coil or twist in the middle of the loop.
2. Position over the treatment area. Hold the skin taut with one hand, or ask someone to help you hold it taut. The twisted section of the thread should sit directly over the row of hairs you intend to remove, with the thread flat against the skin.
3. The scissor motion. Open the fingers of one hand while simultaneously closing the fingers of the other — like a slow scissor. This rolls the twisted section across the skin. As the twist moves, it catches hairs between the loops and pulls them from the follicle. The motion should be smooth and controlled: too fast and you lose grip; too slow and the thread bounces off the surface without catching.
4. Move progressively. After each scissor motion, reposition the thread to the next section. Work systematically across the area rather than repeating the same spot — repeated passes on the same follicle increase irritation without improving the result.
5. Reshape as needed. The twist loosens after several passes. Re-twist the centre section as needed to maintain the grip pattern. A loose, unstructured twist does not trap hairs effectively.
Body area guidance
Eyebrows. Threading's most common use — the precision allows individual hair removal along the brow line. Arch definition and stray hair removal are well within the technique's capability once the scissor motion is reliable. Work in short rows following the natural brow shape.
Upper lip. A small, curved surface — work with the thread flat against the skin, making short passes along the lip line. The upper lip is more sensitive than the brow; redness typically resolves in 30 to 60 minutes.
Chin and jaw. Fine hairs on the chin and jaw respond well to threading. Coarse terminal hairs (often hormonal) may require more passes, and the follicle is more robust — expect slightly more discomfort.
Face and hairline. Threading can define the hairline and remove peach fuzz across the full face. For peach-fuzz removal (vellus hair rather than terminal hair), the thread must be held nearly flat against the skin — a steeper angle grips coarser terminal hair more effectively.
Legs and larger body areas. Threading is technically possible on the legs and arms but is rarely used for these areas in practice because the technique is slow relative to the surface area. For larger areas, waxing or sugaring is significantly more time-efficient. Threading's precision advantage becomes irrelevant at scale.
Bikini line. Some practitioners thread the bikini line; it is not commonly done at home due to the angle of the groin crease and the sensitivity of the area. Shaving or sugaring is generally more practical for home use on the bikini area.
Aftercare
Immediately after: Apply a cool, damp cloth to the treated area to reduce redness. A fragrance-free soothing gel or plain aloe vera can be applied after patting dry.
24 hours: Avoid sun exposure, hot baths, saunas, and skincare products with fragrances, retinoids, AHAs, or BHAs on the treatment area. Per AAD guidance, follicles are temporarily open after root-removal and more reactive to heat and external irritants for the first 24 hours.
Ongoing: Gentle exfoliation two to three times per week as hair regrows helps prevent ingrown hairs by keeping dead skin from trapping regrowth. Wait at least 48 hours after threading before starting this routine. Per DermNet NZ guidance on pseudofolliculitis, ingrown hairs are a possible complication of any root-removal method and are best managed with consistent, gentle exfoliation between sessions.
Threading vs. other methods
Threading sits in the root-removal tier alongside waxing, sugaring, and epilation — results last weeks rather than days. Its practical differentiation is precision and chemical simplicity: it can target individual hairs, leaves no residue, and requires no product beyond a strand of cotton. The trade-off is speed: threading is slow relative to the area covered and demands a technique that takes real practice to develop.
For larger body areas and for edge-work between threading sessions, a multi-blade razor gives you surface-level precision without the root-removal time commitment.

Frequently Asked Questions
What is threading and how does it remove hair?
Threading is an ancient hair removal technique that uses a doubled, twisted strand of cotton thread to trap hairs and pull them from the follicle. The thread is looped and twisted into a figure-eight or coil shape; one section is held taut with the fingers while the other is held with the mouth or a second set of fingers. The twisted section rolls across the skin in a scissor-like motion, catching hairs in the twist and removing them at the root. Because it pulls from the root rather than cutting at the surface, results last several weeks — similar to waxing and sugaring. Threading leaves no chemical residue and uses no heat, making it one of the lowest-irritant root-removal options, per NHS guidance on hair removal methods.
What do you need for at-home threading?
You need a single strand of cotton thread — standard sewing thread or dedicated threading thread, about 40 to 50 centimetres long. Tie the ends together to form a loop. No other products are strictly required, although clean dry skin, good lighting, and a mirror improve accuracy. Cotton thread is the standard; synthetic thread (polyester) does not grip hair as effectively and is not recommended. Threading is one of the simplest setups of any root-removal method — the technique itself is the entire learning curve.
How do you do the threading technique step by step?
Cut 40–50 cm of cotton thread and tie the ends to form a loop. Hold the loop taut between both hands and twist one end six to eight times to form a twisted centre section — this is the working part. Position the twisted section over the hair you want to remove, with clean skin held taut. Open the fingers of one hand while closing the other in a scissor motion — this rolls the twist across the skin, trapping and pulling hairs from the follicle. Move progressively through the area, repositioning the twist. The key is keeping the skin taut throughout: loose skin allows the thread to slip rather than grip.
Is threading safe for sensitive skin?
Threading is generally considered suitable for sensitive skin because it uses no chemicals, no heat, and no adhesives. The primary risk is mechanical: friction from the thread can cause temporary redness, and if the technique is incorrect or the thread angle is too steep, surface skin can be nicked or irritated. Per AAD guidance, anyone with very thin or fragile skin (from tretinoin use, systemic steroids, or conditions like eczema) should approach threading cautiously and avoid treated areas. Threading is not suitable for skin with active breakouts, open wounds, sunburn, or severe rosacea — the mechanical action can worsen inflammation in these cases.
When should you see a doctor after threading?
See your GP if you develop signs of follicle infection after threading: redness that spreads beyond the threaded area, pus-filled bumps, warmth around follicles, or bumps that have not resolved after one to two weeks. Per NHS guidance on hair removal, folliculitis (infection of the hair follicle) is a possible complication of any root-removal method. Mild redness and small bumps that fade within a few hours are normal. A reaction that worsens or spreads, or any sign of systemic infection (fever, flu-like symptoms), needs medical assessment promptly.
