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.

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
Wavy Nail Hair is attached to your natural hair by melting small keratin bonds with a dedicated heat tool. The result is a secure, permanent extension that blends seamlessly with your own hair.
The hair extensions are 100% human hair and the bonds are made of keratin, a protein already present in your natural hair. This choice of material ensures a gentle attachment and a genuine look.
You can curl, straighten and blow-dry the human hair extensions just as usual to vary your style. Be careful to keep hot styling tools away from the keratin bonds so they don't melt.
Yes, the method can be adapted by having your hairdresser split the keratin bonds in half for an even finer attachment. This makes it an excellent option even for fine hair, as long as your scalp is healthy.
A full extension usually needs 100 to 140 strands depending 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 to add 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.
Match the shade of the hair extensions to the colour of your own ends and lengths for the most natural blend. Mixing two similar shades can also create a very lively, multidimensional look.
As the hair extensions are human hair, they can be toned darker, but we don't recommend bleaching or lightening. Please note that any chemical treatment is at your own risk and can shorten the life of the hair.
With correct fitting and regular care, the hair extensions last about three to four months before they need removing or refitting. The hair's texture and quality are best preserved if you follow our specific moisture and washing routines.
The difference from our regular straight Nail Hair is the built-in wavy texture, which gives an instant fall without extra styling. Compared with Tape Hair, this method uses smaller bonds, making it easier to wear your hair in tight ponytails.
Before bed, it's important to brush through your hair gently to avoid tangles at the scalp. Then gather the hair into one or two soft braids to protect the bonds and keep the natural waves overnight.
