The method
Micro bond hair extensions is a method using lightweight keratin capsules weighing 0,1-0,5 grams, which are pressed into flat bonds and blend invisibly with your own hair. It is one of the most balanced keratin methods. It is strong enough to hold securely, and light enough to stay invisible.
Each 0.1 g - 0.5 g capsule contains professional-grade Italian keratin, which forms a strong bond with your hair when heated to 200 °C on a calibrated tool. The result is a durable bond that lasts from 2 to 4 months, depending on how fast your hair grows and how you care for it.
Micro bond hair extensions at AV Extension combines three things that ordinary salons overlook: Premium Slavic hair and baby hair, with an intact cuticle, which keeps its natural movement and shine for 12 months, baby hair along the hairline, which creates a soft edge instead of a hard line, and the flat-pressing technique, refined since 2016, which turns a round capsule into a thin, flexible disc less than 1 mm thick that disappears completely to the touch and in direct light.

The hair
Many London salons use cheap processed hair with the cuticle stripped off, coated in a temporary silicone that imitates the shine of European hair. This coating washes off within 3 to 5 washes. After that the hair tangles into knots, loses its shine and looks visibly artificial.
Premium Slavic hair and baby hair is built differently at the structural level. Each strand is taken from a single donor in Eastern Europe, where the hair structure is close to Western European hair. The cuticle layer stays 100% intact from root to tip. An intact cuticle reflects light the same way your own hair does, moves with the same weight and flows the same way, and stays soft for 12 months rather than 6 to 8 weeks.
Baby hair is ultra-fine strands weighing 0.1 to 0.15 grams, attached along the entire hairline, at the temples and the nape. A natural hairline always has fine vellus hairs that create a smooth transition. Without this detail, micro bond hair extensions looks like a wig, however good the capsule is. With it, the result is indistinguishable from your own hair growth.
AV Extension sources Premium Slavic Remy hair and baby hair only from trusted European suppliers with full traceability. All lengths from 35 to 70 cm are available, every colour from platinum to deep dark, every texture from straight to naturally wavy. Each strand is checked twice for cuticle direction before work, so the hair does not tangle. If you would like coloured strands or individual strand colouring, see our mixed-colour hair extensions.
| Parameter | Premium Slavic Remy hair | Cheap processed hair |
|---|---|---|
| Cuticle | 100% intact from root to tip | stripped off |
| Coating | none | temporary silicone |
| Stays soft | 12 months | 6 to 8 weeks |
| Source | a single donor in Eastern Europe | mixed |
| Lengths | 35 to 70 cm | limited |
The technique
Standard capsules weighing around 1 gram create serious strain at the point of attachment near the root. That weight pulls the hair down, overloads the root and, over time, can weaken and damage your own hair, especially fine hair prone to breakage.
The AV Extension team uses a different approach to micro bond hair extensions. Our flat-pressing technique forms a neat, almost flat bond and creates the most natural and invisible transition between the extensions and the client's own hair. The capsules, weighing 0.1 to 0.15 g, stay very small and light, so they do not overload the root and leave the hair free to grow calmly together with the extensions.
The flat-pressing technique at AV Extension removes capsule bulge completely through seven precise steps, refined since 2016, over which more than 2000 hair restorations have been carried out.
| Weight | 0.1 g - 0.5 g |
|---|---|
| Activation | exactly 200 °C |
| Bond profile | flat, less than 1 mm thick |
| Keratin | professional-grade Italian |
1
The hair is divided into horizontal sections exactly every 1 cm, from the nape to the crown. An even spacing ensures the weight is distributed evenly and stops the load gathering on one area of the scalp.
2
Each section is divided into micro-strands of 10 to 20 natural hairs, depending on the thickness of your hair. In dense areas more hair goes into a capsule, in sparse areas less. This adaptive density does not overload weaker areas.
3
Hair grows in spirals, curves and angles that are unique to each zone of the head. Each capsule is placed exactly along the growth direction in that spot. Capsules placed against the growth create tension and shift within a few days.
4
Each Italian keratin capsule of 0.1 to 0.15 g is heated to exactly 200 °C on a temperature-calibrated tool. Below 180 °C the bond does not form; above 220 °C the hair structure suffers.
5
After heating on the tool to the right temperature, each capsule is shaped and pressed by hand, with clean fingers, one by one. The stylist uses a special, refined technique to create that invisible flat capsule and the most natural transition between the client's own hair and the natural extension strands. Each bond is worked individually, so the transition is soft, even and invisible.
6
Ultra-fine baby hair is attached along the entire hairline, at the temples and the nape, creating a smooth transition and a soft edge. This detail is what separates a professional result from an amateur one.
7
All the added hair is blended with your own through a careful cut, thinning and texturising. You leave with a finished style, not with untreated strands that need a separate trip to the hairdresser.
Procedure time: from 3 to 7 hours depending on the number of capsules
Number of capsules: from 250 to 700+ for a full head depending on the desired density.

Who it is for
Micro bond hair extensions is ideal if any of the following applies to you:
If any of this is you, micro bond hair extensions gives the optimal balance of reliability, invisibility and durability.
How long it lasts
Micro bond hair extensions lasts from 2 to 4 months until a maintenance appointment or removal.
The real timeframe depends on six factors:
at 1.5 cm of growth per month, maintenance is needed sooner than at 1 cm, because the capsules move away from the scalp faster.
daily washing shortens the timeframe to 2 months. Washing 3 to 4 times a week extends it to 3 to 4 months.
sulphate shampoos break down keratin bonds 40% faster than sulphate-free ones. Oil-based products at the roots cause the capsules to shift.
regular styling above 180 °C weakens the capsules. Keeping a hot tool below 180 °C at the roots lets the capsules last the full wear period.
intense sport with frequent sweating calls for more frequent maintenance. Sweat contains salts that gradually weaken the keratin bonds.
routine - if you follow the recommendations, the timeframe increases noticeably. For those who ignore care, the capsules fail within 6 to 8 weeks.
Every AV Extension client receives a personal written care protocol, tailored to her hair type, lifestyle and styling habits.
Use only a sulphate-free, paraben-free and silicone-free shampoo. Apply it only to the scalp. Massage gently with your fingertips, not your nails. Rinse thoroughly with warm water. Apply conditioner only from mid-length to the ends, not on the capsules or the roots. Wash at most 3 to 4 times a week, not every day.
Detangle from the ends upwards in sections of about 5 cm. Never brush wet hair. Always fully detangle the hair before washing. Brush at least twice a day so that mats do not form at the roots.
Before bed, braid a loose plait or a low ponytail with a silk tie. Do not go to sleep with wet or damp hair - it causes friction and tangling. Use a silk or satin pillowcase. Cotton creates friction and tangles the extensions.
Apply heat protection before any hot styling. Keep the temperature below 180 °C near the capsules. Never aim heat directly at the capsules. Above 180 °C the capsules soften and fail before time.
Before chlorinated or salt water, braid the hair tightly. Rinse it with clean water immediately after swimming. Apply a leave-in conditioner before the water as a protective barrier. Without protection, chlorine breaks down keratin quickly.
Book a maintenance appointment every 6 to 8 weeks to check the capsules, reposition grown-out ones and remove problem ones. This extends the overall wear period and prevents tangling.

Growth plan
AV Extension offers something no other salon in London does: a personalised hair-growth plan, built around your goal, where micro bond hair extensions works as protection during the growth period.
Most often a client wants temporary length while she grows out her own hair. Ordinary salons simply fit the extensions and send you home. AV Extension builds a strategy to grow your own hair, using micro bond hair extensions as a protective tool. For 90% of our clients, micro bond hair extensions helps preserve and grow their own hair thanks to light capsules and careful work.
This approach turns micro bond hair extensions from a temporary accessory into a tool for growing your own hair.
Short hair
Yes. AV Extension specialises in micro bond hair extensions on hair as short as 3 cm. This requires an adapted technique, because short hair has little length to grip.
Short hair needs from 400 to 700 capsules. More attachment points spread the weight across a greater number of strands and reduce the load on individual short hairs.
The capsules are placed closer to the scalp (1.5 mm from the root versus the standard 2 mm), to make the most of the short length and hold securely.
The growth direction is mapped especially carefully. Even a small deviation on short hair leads to shifting within the first week.
Short hair takes noticeably more baby hair (up to 40% of all capsules) to hide the transition zones and make the length gradual.
Each strand is tested for strength before attachment. Strands that are too weak are skipped, so there is no breakage.
Not sure whether micro capsules will suit your short hair? Book an in-person consultation where 5 trial capsules are applied, so you can see and feel the result before a full installation.
Trial consultation: £50 (fully credited towards the cost of the extensions if you decide within 3 days).
This trial removes all doubt and gives an honest assessment of feasibility.
