Sew-in hair extensions in Stockholm and Uppsala

Longing for hair with incredible fullness and length that stays securely in place and feels like your own? Sewing in hair extensions, also known as weaving, is one of the most tried-and-tested, gentle, and beloved methods of hair extension. It is perfect for anyone who wants a beautiful, long-lasting result without using glue, heat, or chemicals. By creating a thin, discreet braid close to the scalp and gently sewing the weft into place, a seamless transition is achieved. This gives your hair fantastic movement, luxurious thickness, and natural flow that follows your own features with every step you take.

The best thing about sew-in hair extensions arrow-icon
  • Completely free from chemicals: The method uses no glue, tape, or intense heat, providing maximum protection for your own hair.
  • Optimal protection: Your natural hair rests in the braids during the process, reducing daily wear and tear.
  • Secure and full: Provides fantastic volume from root to tip and stays so securely in place that you can exercise and live just as usual.
  • Concealed attachments: The hair wefts lie flat against the head, making it easy to create high, beautiful updos without visible attachments.
Who is sewn-in hair suitable for? arrow-icon

This method is ideal for those with normal, slightly thicker, curly, or textured hair, as your own hair needs to be strong enough to support the thin braids securely. It is also the perfect choice for those who want permanent hair extensions but wish to avoid chemical products, glue, or heat tools on the scalp.

Which hair extensions are used for sew-ins? arrow-icon

This method uses a hair weft - a long curtain of hair that is cut to your measurements. At Fairwithhair, we only use 100% genuine premium hair with thin, flexible edges that blend in seamlessly. Thanks to our wide range of textures, from pin-straight to deeply curly, you get a completely natural fall. The high quality also means that the hair can be reused several times.

Consultation & color matching: We select the right shade, texture, and length to perfectly match your natural hair.

Braiding the base: We create thin, secure cornrow braids close to the scalp, strategically placed so that your top hair conceals them.

Sewing in the wefts: Using a special needle and thread, we gently sew the hair wefts onto the braids. This distributes the weight evenly and securely.

Styling: We blend the extensions with your own hair for an invisible transition and finish by styling your new dream hair.

The treatment is available at both of our salons, in Stockholm and Uppsala.

Vanliga frågor om att sy in löshår i Stockholm

Vad är sy in löshår?
Insytt är en metod där håret flätas i tunna cornrow-flätor och löshårstränsar sys fast på flätorna med nål och tråd. Inga kemikalier eller lim används – fästet är helt mekaniskt och hållbart.
Kan jag styla håret som vanligt?
Ja. Äkta hårträns kan stylas, lockas och plattas precis som ditt eget hår. Använd alltid värmeskydd för att förlänga hållbarheten.
Hur tvättar jag insytt löshår?
Tvätta med återfuktande schampo och balsam. Massera försiktigt vid hårbotten och låt helst håret lufttorka. Vi ger dig detaljerade skötselråd efter din behandling.
Hur lång tid tar behandlingen?
En insättning tar vanligtvis 1,5–3 timmar beroende på hur mycket hår du sätter in och vilken längd du väljer.
Hur lång tid tar återbesöket?
Ett återbesök (uppflyttning) tar normalt 1–2 timmar.
Känns insytt löshår obekvämt?
Det kan kännas lite spänt de första dagarna, men de flesta vänjer sig snabbt. Om du upplever ihållande obehag hör du av dig till oss – det ska inte göra ont.
Vad är skillnaden mellan sy in och tape extensions?
Sy in använder tråd och flätor – helt utan lim. Tape extensions fästs med tejp och behöver bytas ut och tas bort av frisör. Sy in är ofta skonsare och håller längre mellan behandlingarna.
Kan jag köpa löshåret hos er?
Ja! Vi säljer Luxury hårträns i äkta Remy-hår direkt i vår webbutik och i salongen, i rak, vågig och lockig struktur, från 40 till 70 cm
Kan jag simma och träna med insy?
Ja, insy är en av de metoder som tål ett aktivt liv bäst. Täck håret vid simning i klor och skölj noga efteråt.
Vad kostar insy?
Priset varierar efter mängd hår, längd och om du tar med eget löshår. Kostnadsfri konsultation ger dig en tydlig prisuppskattning.

Sew-in hair extensions - a gentle and timeless method for your dream hair

Are you longing for hair with incredible fullness, luxurious length, and natural movement that lasts week after week? Sewing in hair extensions, also known internationally as weaving or hair weave, is one of the most tried-and-tested and beloved methods of hair extension. The technique has been worn and refined by women around the world for generations and is the perfect choice for anyone who wants a long-lasting transformation without compromising the health of their own hair. At our salons in Stockholm and Uppsala, we help you tailor extensions or added thickness that blend seamlessly with your natural hair.

What makes this method so unique is that it is completely free from glue, harsh chemicals, tape, and intense heat. Instead, our stylists create one or more thin, discreet cornrow braids close to your scalp. A soft hair weft is then sewn onto these braids using a special needle and thread. Because the weight is distributed evenly along the entire braid, the strain on individual strands is minimized. This makes the method one of the gentlest extension methods on the market, allowing your own hair to rest and grow undisturbed while you wear the extensions.

Maximum volume and flexibility in everyday life

When you have your hair extensions sewn in at Fairwithhair, you get a result that gives you freedom in everyday life. Because the wefts are sewn onto a secure base, the hair stays firmly in place whether you work out intensely, swim, or style your hair often. The braids and attachments are placed strategically and concealed by your own top layer of hair. This means you can confidently wear your hair in a high ponytail, braid it, or create elaborate updos without any seams showing through.

Our extensions are made from 100% genuine premium-quality human hair. This means you can treat, shape, straighten, and curl them just like your own hair. The method also suits many hair types. Whether you have naturally curly, wavy, or slightly coarser hair, or finer hair but want a stable and full solution, we adapt the braiding technique and amount of hair to your individual needs.

Care and maintenance

To keep your new hair soft, shiny, and tangle-free month after month, proper aftercare is essential. Since hair extensions do not receive the scalp's natural oils, they need extra moisture. Use gentle, moisturizing products and regularly give the lengths a nourishing hair mask. When washing your hair, gently massage the scalp between the rows and avoid rubbing the braids themselves.

After washing, it is important to blow-dry the base and braids completely on low heat. This keeps the scalp healthy and balanced. Brush your hair gently morning and evening with a brush designed for hair extensions, and hold the attachment with one hand so that you do not pull on the braids. Sleeping with a loose braid is a good way to protect against friction. Because the hair is of such high quality, you can reuse the same weft several times - we remove the hair, re-braid your regrowth, and sew the weft back in during your follow-up appointment.
