What it looks like
Small strands with a keratin bond
Keratin extensions, also called nail hair, are human hair in small strands with a keratin bond at the top. Each strand is attached to a thin strand of your own hair with heat, so the bond forms around the hair.
- 1. What?

- 3. How long?
- 3–4 months, then re-bonding
- 4. Pros/cons?
- Moves freely and naturally – needs a skilled hand
How it is installed
Strand by strand
- We section off a thin strand of your own hair
- The keratin bond is placed on the strand and shaped around the hair with heat
- We continue strand by strand until the amount is right
- After 3–4 months we re-bond
When re-bonding we release the bond with remover and set the strand again with new keratin bonds – it is not moved up like tape or micro rings.

Frequently asked questions about keratin hair extensions
Nail Hair is applied by attaching small keratin bonds around your own hair using a gentle heat tool. This method gives a secure, permanent hair extension that stays firmly in place around the clock.
The hair extensions are 100% human hair and the bonds are made of keratin, a protein already found naturally in hair. This makes the extension look completely genuine and minimises wear on your own hair.
You can use heat tools on the human hair extensions to adjust your styling and shape the curls as needed. Be very careful never to apply direct heat to the keratin bonds themselves, as they can melt.
Your hairdresser can easily cut the keratin bonds in half to create even smaller, lighter bonds. This makes the method safe and gentle even if you have finer hair, as long as your scalp is healthy.
For a full extension we recommend 100 to 140 strands, depending entirely on the thickness of your natural hair, and 160 to 200 strands for thicker hair, a short haircut or a length of 60 to 70 cm. If you only want extra volume, 40 to 80 strands is usually enough, and 20 to 40 for a few accent strands. The strands are sold in packs of 20 and each strand weighs one gram.
For a seamless blend, match the colour of the hair extensions primarily to the tone of your own ends and lengths. Mixing two similar shades when fitting is also a great way to create an extra lively and natural result.
As the hair extensions are human hair, they can technically be toned darker to match your own shade perfectly. We strongly advise against any form of bleaching, though, and any chemical treatment is at your own risk as it can shorten the life of the hair.
With the right care, a fitting usually lasts three to four months before it's time to remove the bonds or have a move-up. To keep the hair extensions' Deep Wave texture and soft quality for longer, it's important to follow our moisture routines carefully.
The difference from our straight or wavy Nail Hair is the dense Deep Wave texture, which gives maximum volume and intense texture straight away. Compared with Tape Hair, this method uses small bonds that make advanced updos easier without any risk of them showing.
Before going to bed, gently separate the hair with your fingers or a wide-tooth comb to avoid tangles near the scalp. Then braid the hair into one or two loose braids to protect both the bonds and the shape of the curls all night.
