Teflon / PTFE Coating
Description
Teflon (PTFE) coating reduces friction on scissor blades for smoother cutting action. Learn how this non-stick layer performs in salon use and how long it lasts.
Teflon / PTFE Coating (テフロンコーティング)
Quick look
- Technical name: Polytetrafluoroethylene (PTFE), commercially known as Teflon
- Friction coefficient: Approximately 0.05–0.10 — lower than any common PVD coating or polished steel
- Chemical resistance: Highly resistant to the acids, alkalis, and oxidising agents common in salon environments
- Best for: Colour specialists, keratin and smoothing treatment work, any stylist dealing with heavy product accumulation on blades
Why it matters
PTFE is a fluoropolymer with a friction coefficient lower than any alternative scissor coating and near-zero reactivity with most salon chemicals. Hair, colour developer, styling product, and rinse water slide off a PTFE-coated blade surface rather than accumulating — which matters in colour-heavy or product-heavy environments where uncoated scissors require more frequent mid-session wiping to maintain smooth cutting action.
The hydrophobic character of PTFE reinforces this. Water and water-soluble products bead and run rather than sheeting and sitting on the blade, which reduces the moisture contact time that accelerates corrosion in a salon environment. In a high-volume colour room where scissors may encounter developer, bleach, toner, and acidic conditioning agents across a single working day, PTFE’s chemical inertness extends service life compared to bare or lightly coated steel.
Durability comparison
PTFE is softer than PVD coatings. Where TiN or TiAlN holds its mechanical properties for the working life of the scissors, PTFE wears under friction — particularly at the cutting edge zone, which is reground during each sharpening service anyway. On the blade face, PTFE coating can thin over 12–24 months of professional daily use and may need reapplication, depending on cleaning methods and cutting volume.
High-heat sterilisation is incompatible with PTFE. The coating begins to degrade above approximately 260 °C and releases compounds at higher temperatures that require proper ventilation. Standard autoclave protocols at 134 °C for 3 minutes sit below the PTFE threshold, but verify with the scissors manufacturer before using any heat-sterilisation method.
Shear pairing and compatibility
- Colour-specialist scissors used during and immediately after bleach and developer application
- Thinning shears where product buildup between teeth degrades efficiency fastest
- Wet cutting blades in high-humidity climates where moisture contact time is extended
Technique map and services
- Balayage and foil work where developer contacts tools throughout the session
- Keratin and smoothing treatments where silicone-heavy products coat every tool surface
- Quick-turnaround salons where cleaning time between clients must be minimised
Watch-outs and care
- PTFE wears faster than PVD — plan for potential reapplication over the scissors’ service life.
- Not suitable for high-heat sterilisation above 260 °C. Confirm autoclave compatibility before using.
- Re-coating services exist but are not universally available; work with a specialist service rather than a standard sharpener.

Frequently Asked Questions
A coefficient of friction of roughly 0.05 to 0.10 — the lowest of any common scissor coating. Hair, chemical residue, and styling product slide off the blade surface rather than accumulating between cuts, which is especially valuable in colour-treated hair environments where dye, developer, and conditioning agents coat every tool they touch. The hydrophobic nature of PTFE also means water beads and runs off, reducing moisture contact time and slowing corrosion.
PTFE is soft relative to PVD coatings and wears faster — you may need reapplication over the life of the shear, whereas a properly applied PVD coating lasts the scissor’s full service life. PTFE is also unsuitable for high-heat sterilisation methods because it degrades above approximately 260 °C. For stylists who prioritise function over longevity and want maximum product-repellence during chemical services, those trade-offs are often acceptable. For a permanent coating, PVD is usually the better investment.
Yes, but availability varies. Re-coating services exist but are not universally offered — you may need to work directly with a specialist service rather than your regular sharpener. Sharpening removes the coating from the blade edge automatically (expected, and does not affect cutting performance), but when the coating wears off the flat faces of the blade, the non-stick benefit disappears. Plan for reapplication roughly every few years under heavy chemical-service use.
