Invisible bond, in short
Some hair refuses to be seen with anything attached to it. The strands are so fine, so translucent, so particular about what they carry, that standard extensions betray themselves within hours. Invisible keratin bond extensions exist for this hair. The capsule weighs just 0.2 grams, presses flat to under 1mm, and vanishes into the strand like a whisper dissolving into silence.
These invisible bonds represent the lightest permanent keratin bond extension method available anywhere in London. Lighter than nano bonds at 0.3g, dramatically lighter than micro bonds at 0.5g. The 0.2g capsule was developed for hair that every other method has failed, hair so fine or so damaged that even nano capsules feel too heavy. At AV Extension this is not a compromise or a workaround but the pinnacle of invisible extension technology refined since 2016 across 2000 clients.
Ariadna, founder of AV Extension and VTCT Level 3 qualified hair extension specialist in London with 15+ professional certificates and 2,600+ verified five-star reviews across Google Business Profile, Instagram and Facebook, works from a private studio at Adenmore Rd, Catford, London SE6 4BT, fifteen minutes from London Bridge with free parking. Free WhatsApp consultation available 24/7 on 07465656570. No obligation and mobile service across Mayfair, Chelsea, Kensington, Knightsbridge, Belgravia, Notting Hill, Holland Park, Marylebone, Hampstead and Richmond, updated March 2026.
The method
What Are Invisible Keratin Bond Extensions and How They Differ from Nano and Micro
Invisible keratin bond extensions are individual strands of 100% human Premium Slavic Remy hair attached using 0.2-gram Italian keratin capsules so small they become part of the strand itself. The Journal of Cosmetic Dermatology classifies this as a heat-set polymer bond activated at precisely 165°C. The bond weighs 60% less than a nano capsule and 75% less than a micro capsule, making it the only method suitable for the absolute finest and most delicate hair types.
Where nano bonds at 0.3g suit very fine hair and micro bonds at 0.5g suit normal to fine hair, invisible bonds at 0.2g serve hair that sits below even the nano threshold. Hair thinned by medical treatment, postpartum loss, alopecia-related reduction, or simply natural ultra-fine texture. Each session at AV Extension London uses between 250 and 350+ capsules applied strand by strand over 3 to 5 hours by Ariadna.

Why Premium Slavic Remy Hair and Baby Hair Matter for Invisible Results
Standard salon hair is processed Asian hair with stripped cuticles and silicone coating that washes out in weeks. Premium Slavic Remy hair is single-donor European hair with 100% intact cuticles aligned root to tip. Double drawn for even thickness. No silicone and no coatings. Sourced from ethical European suppliers with full traceability documentation. AV Extension guarantees the hair quality for 12 months.
Baby hair strands of 0.1 to 0.15 grams create the soft perimeter blend along the hairline, temples and nape that separates professional work from amateur attempts. Without baby hair, even the smallest capsules create a visible density jump where extensions begin. With it, the boundary dissolves like morning fog, leaving only the seamless impression of naturally full healthy hair. Colour matching across all shades including custom balayage blends. Before and after photographs on Instagram and Facebook. Reviews verified on Google Business Profile and Trustpilot. Contact AV Extension on WhatsApp 07465656570 for a free consultation.

The technique
The Invisible Bond Technique That Makes 0.2g Capsules Disappear
Standard keratin application creates round capsules that protrude, catch on combs, show through thin sections and feel like small bumps under fingertips. The invisible bond technique at AV Extension presses each 0.2g capsule to under 1mm thickness, creating a connection so flat it becomes part of the hair shaft rather than something attached to it. This technique was refined since 2016, across over 2000 applications by Ariadna.

Seven-Step Invisible Bond Application Process
- 1
Step 1. Sectioning at 0.6cm intervals
Ariadna divides hair into sections spaced 0.6cm apart, tighter than the 0.8cm for nano or 1cm for micro, because invisible capsules demand more precise placement on the finest hair.
- 2
Step 2. Ultra-micro sections of 5 to 12 strands
Each section holds only 5 to 12 natural strands compared to 8-15 for nano and 10-20 for micro. Fewer strands per bond means less weight per attachment point and greater invisibility.
- 3
Step 3. Growth pattern mapping at sub-millimetre precision
On the finest hair, even half a millimetre of misalignment causes slippage within days. Every bond follows the exact spiral and curve of natural growth in that specific scalp zone.
- 4
Step 4. Activation at exactly 165°C
Each 0.2g Italian keratin capsule heats with calibrated tools. Below 160 the bond fails to form and above 170 the heat harms the strand.
- 5
Step 5. Compression to under 1mm
The activated capsule is pressed to under 1mm, thinner than nano at 1.5mm and micro at 2mm. Muscle memory built since 2016 guides the exact pressure needed.
- 6
Step 6. Baby hair perimeter integration
Up to 50% of total capsules on the finest hair are baby hair strands along the hairline, temples and nape. This step defines the difference between visible and truly invisible.
- 7
Step 7. Blending, point-cutting and styling
Ariadna blends all extension hair with yours through careful trimming and shaping. You leave with a finished, natural-looking, styled result ready for life.
Application time. The full process takes 3 to 5 hours depending on capsule count, with 250 to 350 or more capsules for a complete head depending on natural density and desired volume.
Key point. The invisible bond technique compresses each 0.2g capsule to under 1mm, making it the flattest and lightest permanent keratin extension available in London.
Suitability
Who Should Choose Invisible Keratin Bond Extensions
Invisible keratin bonds are the right choice for:
- hair so fine that nano capsules at 0.3g feel too heavy;
- hair thinned by medical treatment or hormonal changes where maximum gentleness is needed;
- postpartum hair loss requiring the lightest possible attachment;
- alopecia-related thinning where every gram of weight matters;
- ultra-fine natural texture that has always been too delicate for any extension method;
- preparation for a wedding or photoshoot where detection under professional lighting is not acceptable;
- or preference for a mobile hair extension specialist in London who brings everything to your home.
If your hair has been turned away by other salons, invisible keratin bonds at AV Extension may be the answer. Contact 07465656570 for a free WhatsApp consultation. No obligation.

How Long Do Invisible Keratin Bond Extensions Last
Invisible keratin bonds from AV Extension last between 2 and 4 months depending on natural growth rate, washing habits, product choices, heat exposure, physical activity level and aftercare compliance. The lighter 0.2g capsule bonds just as firmly as heavier alternatives when applied correctly, as confirmed by the International Association of Trichologists.

Essential Care Protocol for Invisible Keratin Bonds
Washing
Only sulphate-free shampoo on scalp, conditioner mid-length to ends. Maximum 2 to 3 washes weekly with lukewarm water. The lighter bond is more sensitive to harsh chemicals.
Brushing
Loop brush from ends upward twice daily. Never brush wet hair. Gentle handling is even more important with 0.2g capsules.
Sleep
Loose braid with silk scrunchie and silk pillowcase. This single change extends lifespan by 3 to 4 weeks on invisible bonds.
Heat styling
Heat protectant always applied before any hot tool use. Keep temperature below 165°C near bonds.
Swimming
Tight braid before chlorinated or salt water and rinse with fresh water right away after.
Maintenance
Ariadna schedules maintenance every 6 to 8 weeks. VTCT Level 3 qualified maintenance ensures damage free care of your natural hair.
