The difference between ordinary extensions and the ones that make people lean closer, touch their own hair, and quietly ask where did you get these done sits entirely in the raw material. Premium Slavic Russian hair carries a particular weight and lustre that synthetic blends and processed Asian or Indian hair simply cannot replicate. Each strand collected from donors across the Slavic regions of Russia, Ukraine, and Belarus holds its cuticle layer intact, aligned in a single direction. That alignment is not a marketing phrase. It is the physical reason the hair resists tangling, holds colour, and moves the way your own hair moves when it catches a breeze through an open car window.
At AV Extension London, we work exclusively with this grade of hair. No blends. No substitutions. Ariadna, our lead specialist with VTCT Level 3 NVQ certification, 8+ years of hands-on experience, 15+ professional diplomas in hair extensions, and a client book of over 6,000 women across London, selects every batch personally. The reason is plain. When you bond premium Slavic Russian hair extensions to a client's natural hair using Italian keratin, the quality of the source material and the bonding agent together determine whether the result lasts three months or twelve. We aim for twelve.
The method
Hair markets sell dozens of labels. Double-drawn, virgin, Remy, temple hair, European. Most of these terms describe processing methods, not origin. Slavic Russian hair describes both. The donors live in regions where cold winters and specific genetics produce hair that is naturally fine in diameter yet dense in volume. Strong without being coarse. Smooth without being limp. This particular combination of qualities makes premium Slavic hair the gold standard among extension specialists who value longevity and natural integration above all else.
When a strand of premium Slavic hair reaches our studio, every cuticle scale still faces the same direction it grew in. Cheaper hair goes through acid baths that strip the cuticle entirely, then coated with silicone to fake the shine. That shine washes out by the third shampoo. Ours does not. The hair we work with is Remy-grade, meaning root-to-tip alignment is preserved from the moment of collection through every stage of sorting, washing, and colouring. This is the reason premium Slavic Russian hair extensions resist matting, hold a blow-dry for days, and integrate into your natural texture as though they had always been there. The intact cuticle also explains why clients report their extensions feeling softer with each wash rather than drier, a quality that stripped and coated hair cannot sustain past the first few weeks.
For clients with particularly fine or thin natural hair, we source Slavic baby hair. This is not a clever name for thin adult hair. It is genuine hair collected from very young donors, finer in diameter than any adult strand. The individual fibres measure between 40 and 55 microns, compared to 60 to 80 microns for standard adult Slavic hair. Paired with our invisible 0.2g keratin bonds, baby hair creates a result so subtle that even experienced hairdressers struggle to find the attachment points. This option has become the preferred choice for clients with alopecia, thinning at the temples, or hair that has been weakened by medical treatments or hormonal changes.
Slavic Russian hair arrives in an unusually broad range of natural shades, from ash blonde and cool light brown through warm chestnut to deep espresso. Because the cuticle remains intact, the hair accepts custom colouring with predictable, even results. We colour-match every set to your natural root shade and preferred lengths, blending premium Slavic hair extensions so precisely that the join between your own hair and the bonded strands disappears entirely. Clients who colour their natural hair regularly find that Slavic Remy hair holds salon colour for significantly longer than processed alternatives, reducing the need for frequent toning and extending the time between colour refresh appointments.
Every batch of premium Slavic Russian hair we use is sourced directly from trusted collectors in Russia, Ukraine, and Belarus. The hair is cut, not gathered from brushes or floors, and sorted by length, colour, and texture before it reaches London. Ariadna inspects each delivery against strict quality criteria, rejecting any batch that shows signs of chemical processing, uneven cuticle direction, or inconsistent diameter. This direct sourcing chain eliminates the middlemen who dilute quality by mixing origins, and it allows us to guarantee that every strand bonded to your hair is exactly what we say it is. Traceability is not a trend for us. It is the foundation of the 12-month quality guarantee we place on every set.
The hair
Every extension at AV Extension is attached using Italian keratin bonds, a technique also known as hot fusion hair extensions or pre-bonded keratin extensions. We never use glue, tape, clips, or micro-rings. The premium Italian keratin we work with is a medical-grade protein compound that mirrors the molecular structure of natural human hair. When heated to the precise temperature and moulded around a small section of your hair, it forms a bond that is secure yet gentle, flexible yet lasting. The keratin softens with controlled heat during application and sets into a smooth, flat connection that sits invisible against the scalp. Three bond sizes. One philosophy. Results that people feel before they see.
The micro keratin bond at 0.5 grams suits clients with medium to thick natural hair who want noticeable volume and length. Each bond holds enough premium Slavic Russian hair to add visible body without weighing down the root. The Italian keratin distributes the weight evenly across a wider attachment area, preventing stress on individual strands. Application for a full set takes between 3 and 5 hours depending on the bond count. The bonds sit flat against the scalp, remain comfortable throughout the full wear period of 2 to 4 months, and release cleanly during professional removal without pulling or breaking your natural hair.
For finer hair or areas where discretion matters most, the nano keratin bond at 0.3 grams reduces the attachment point to almost nothing. Lighter on each strand, these bonds distribute weight more evenly and work well on hair as short as 7 cm. The nano keratin bond is our most popular choice among clients who have never worn extensions before and want a natural, undetectable result with premium Slavic hair. The smaller bond size also means faster application times and a more comfortable wear experience, particularly for clients who are active, exercise regularly, or prefer to wear their hair up in ponytails and braids without any visible attachment points.
The smallest in our range. At 0.2 grams per bond, the invisible keratin bond is engineered for the most delicate situations. Growing-out pixie cuts. Alopecia-affected areas. Ultra-fine baby hair around the temples and hairline. Hair recovering from chemical damage or medical treatment. Each bond is so small that it vanishes beneath even the thinnest top layer of natural hair. Combined with Slavic baby hair and our premium Italian keratin, this method produces results that redefine what extensions can achieve on compromised or very short hair. We have successfully applied invisible bonds on natural hair as short as 5 cm, a length that most London salons will not even attempt.
| Hair | Cuticle | Direction | Stays soft for |
|---|---|---|---|
| Premium Slavic Remy | intact | root to tip | 4 to 8 months |
| Processed Asian | stripped | mixed | weeks, then tangles |
| Silicone coated | stripped | mixed | until the coating washes out |
The technique
Who it suits
Premium Slavic keratin bond hair extensions at AV Extension London cost between £500 and £1,900 for a full head application. The exact price depends on the bond count, the weight of premium Slavic hair chosen, the desired length, and whether you visit our Catford Bridge studio or request our mobile service across Central London. We believe that a client who understands exactly what she is paying for is a client who returns. That is why every quote is confirmed in writing during your free WhatsApp consultation, before any appointment is booked. No hidden charges on the day. No surprise add-ons. The Italian keratin, the 100% premium Slavic Remy hair, the application time, the aftercare plan, and the 12-month hair quality guarantee are all included in the quoted price. What you see in writing is what you pay.
Everything begins with a conversation. Send a message to 07465656570 on WhatsApp at any hour, any day. Share photos of your current hair, describe the length and volume you want, ask every question you have. Ariadna responds personally. No bots. No scripted replies. Free WhatsApp consultation 24/7 means exactly that. During this consultation, you will receive a detailed written quote that covers the bond count, hair weight, length, and total cost. You will know the exact price before you make any commitment.
For clients who want to see and feel the result before committing, we offer an offline consultation at our Catford Bridge SE6 studio. During this session, Ariadna applies 5 trial keratin bonds of premium Slavic Russian hair directly into your own hair using the same premium Italian keratin used in full applications. You leave the studio wearing them. Sleep on them. Wash them. Style them. See how they blend with your natural texture over several days. The consultation fee is £50 and includes a detailed analysis of your hair structure, a personalised hair growth plan using extensions, individual aftercare product recommendations, and a written quote for your full set. Many clients book their full application before they leave the studio, because feeling the quality of the Slavic hair and Italian keratin bond on their own head removes every remaining doubt.
A full set of premium Slavic Russian keratin bond hair extensions takes between 3 and 5 hours depending on the number of bonds. The studio at Catford Bridge is private, quiet, and equipped with free parking directly outside. Every bond is placed individually by Ariadna using our signature technique that positions the Italian keratin flat against the scalp, making each attachment point completely invisible under the natural hair. Alternatively, Ariadna travels to your home across 10 of London's most sought-after postcodes, including Mayfair, Knightsbridge, Chelsea, Kensington, Belgravia, Notting Hill, Westminster, Canary Wharf, Marylebone, and St John's Wood. The mobile service delivers identical results to the studio experience, with full equipment brought to your location.
Every client receives an individual aftercare plan tailored to their hair type, lifestyle, and growth goals. We recommend specific products, washing techniques, sleeping positions, and styling methods that protect both your natural hair and the Slavic Russian keratin bond extensions. What separates AV Extension from every other studio in London is what happens after you leave the chair. 24/7 WhatsApp support runs throughout the entire wear period. If a bond loosens, if you have questions about colour refresh, if you are travelling and need styling advice, one message is all it takes.
We also create an individual hair growth plan for every client who wants to use extensions as a tool to grow their natural hair to a desired length. The plan maps out how long each set should be worn, when maintenance appointments should fall, which lengths to choose at each rebonding session, and what nutrition and topical care will support your natural growth rate. Extensions are not just about instant length. They are a bridge between where your hair is today and where you want it to be in twelve months. We guarantee the quality of the premium Slavic hair for 12 months from the date of application.
Longevity
London has no shortage of salons that claim to offer Slavic hair extensions. Many of them do. The distinction lies in three places. How the hair is sourced. How it is bonded. What happens after you leave the chair. At AV Extension, the sourcing is direct and traceable from Slavic regions to our studio. The bonding uses premium Italian keratin in three bond sizes selected for your specific hair type. Whether you know this method as fusion extensions, pre-bonded extensions, or keratin bonds, the result is the same at AV Extension. The aftercare is not a leaflet handed to you at the door. It is a relationship that lasts the full wear period and beyond.
Ariadna has maintained active WhatsApp threads with clients for months at a time, adjusting care routines, scheduling maintenance, answering questions about heat tools and swim holidays and wedding hairstyles. Our technique places each keratin bond so that it sits completely invisible within the natural hair. This is the detail that separates a competent application from one that changes how a woman feels when she catches her reflection. Over 2,600 five-star reviews confirm it. Over 6,000 clients confirm it. And every new client who runs her fingers through the finished result and says I cannot feel them confirms it again.
Growth plan
Our clients come to AV Extension with different starting points, but the most common situations we work with include women growing out a pixie cut or short bob who want length without waiting twelve months for it to grow naturally. Women with fine or thin hair who have been told by other salons that extensions are not suitable for them. Women experiencing thinning or hair loss from hormonal changes, stress, postpartum recovery, or medical treatments. Women with hair as short as 5 to 10 cm who want to add both length and density. Women who have tried tape or clip-in extensions and want a permanent, invisible alternative. And women who simply want the finest quality hair available in London, bonded with a method that protects rather than damages their natural hair.
Regardless of the starting point, the approach is the same. Ariadna assesses your hair structure, selects the correct bond size and premium Slavic hair weight, creates a placement map that maximises coverage while minimising stress on the natural roots, and applies each Italian keratin bond with the precision that only 8+ years and 6,000+ applications can produce.
Short hair
"I spent months researching Slavic hair extensions in London and booked consultations at three different studios before finding AV Extension. The quality of the hair was immediately different. Thicker at the root, softer through the mid-lengths, and a natural movement that the other places could not match. The Italian keratin bonds sit so flat against my scalp that I forget they are there. Six months later, the hair still looks and feels like the day it was applied."
-- Elena, Knightsbridge
"My natural hair is fine and blonde and I had been told by two salons that Slavic hair would be too heavy for me. Ariadna used nano keratin bonds with baby hair and the result is genuinely invisible. My partner did not notice until I told him. The aftercare plan she created for my hair type has actually improved the condition of my natural hair underneath the extensions. That, to me, is the highest compliment a keratin bond extension can receive."
-- Sophie, Chelsea
"The five-bond trial during the consultation changed my mind entirely. I had been considering tape extensions for months but the feel of the premium Slavic Italian keratin bonds on my own hair was something else. No pulling, no bulk at the root, just length appearing where there had been none. The written quote was clear and the final price was exactly what Ariadna had quoted. I booked my full set before I left the studio."
-- Isabella, Mayfair

I have been looking for a professional of high standard for years (and in different cities)and couldn't be happier I have found Arianna's salon. The quality of her work is beyond any praise, she is super-knowledgeable in anything to do with hair extensions and she is just a talented, beautiful person. I no longer have to go to Europe to get extensions which are so tiny, they won't damage my hair and are just invisible. Thank you Ariadna for the amazing experience, you are a gem!
