Nail hair extensions are 100% genuine human hair, attached strand by strand to your own hair by melting the keratin bond with a heat tool. This hot fusion method works on hair from just 6–8 cm long, and the result withstands normal washing, styling and heat exactly as your own hair does.
All of our extensions are made with the double drawn technique: the hair is sorted several times during production and the shortest strands are removed by hand. The strand stays even all the way to the tip, which is what gives the fuller look.
How many do you need? One pack contains 20 bonds, and a full head normally takes 100–160 bonds depending on your starting hair. Pack weight grows with length: roughly 12 g at 40 cm, 14 g at 50 cm, 16 g at 60 cm, 18 g at 70 cm and 20 g at 80 cm.
Available in lengths from 40 to 80 cm and a wide range of shades from light to dark. Delivery across Finland in 2–5 business days, free on orders over 99 €, with a 14-day exchange and return right.

Because this is real hair, you can straighten, curl and colour it just as you would your own. Well cared for, the same hair lasts for several months.
Who keratin bonds suit
- Almost every hair type – the small bonds spread the weight evenly and hold securely.
- The longest wear – the most durable permanent method when you want lasting volume.
- Lengths up to 80 cm – for a dramatic, very long result.
Fitting, wear and maintenance
Keratin bonds are fitted at a salon in roughly 2–4 hours. The bonds stay in place for several months and are moved up every 2–3 months as your own hair grows. Use sulfate-free products and keep oil-based products away from the bonds.
Choosing shade and length
Pick a shade slightly darker than your own hair for the most seamless blend. One pack contains 20 strands, and a full head typically needs 100–160 strands depending on your starting thickness.
Keratin bond or tape?
Keratin bonds last longest and suit nearly everyone. If your hair is fine, or you want the fastest and most affordable permanent option, compare tape extensions as well. Both belong to our hair extensions range.
Frequently asked questions
How long do keratin bond extensions last?
The bonds stay in for several months and are moved up every 2–3 months as your own hair grows. The hair itself lasts considerably longer when cared for properly.
Do keratin bonds suit every hair type?
The small bonds suit almost every hair type. For very fine hair, a lighter tape attachment is often recommended instead.
Is this real human hair?
Yes. All our keratin bond extensions are 100 % real human hair, so they can be styled and coloured like your own.
Do keratin bonds damage your own hair?
Fitted professionally and maintained on schedule, they are gentle on the hair. Regular maintenance and the right care products are what matter most.
How many strands do I need?
A full head usually takes 100–160 strands depending on your hair. One pack contains 20 strands.
