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?

- 3–4 months, then re-bonding
- 4. Pros/cons?

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 attached to your own hair with small keratin bonds gently melted with a heat tool. This creates a discreet, permanent hair extension that stays secure around the clock.
We use 100% high-quality human hair and bonds made of keratin, a substance already found naturally in hair. The human hair lets the extension blend in perfectly and be handled just like your own hair.
As the hair extensions are human hair, you can curl, straighten and blow-dry them however you like. Be careful not to use heat tools directly on the keratin bonds, though, as the heat can melt them.
Nail Hair can be adapted by cutting the bonds in half to make them even smaller and lighter. This makes the method suitable even if you have finer hair, as long as your scalp is healthy.
For a full extension we recommend 100 to 140 strands depending on your own hair thickness, and 160 to 200 strands if you have thicker hair, a short haircut or choose 60 to 70 cm. If you just want to thicken, 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 the most natural result, match the colour of the hair extensions to the tone of your own ends. We offer a wide range of shades, and you can blend two similar colours for extra dimension.
As it's human hair, it can technically be toned darker, but we strongly advise against any form of bleaching. Any chemical treatment is at your own risk and can negatively affect the life of the hair.
With careful care, a fitting lasts about three to four months before it needs to be removed or moved up. The hair extensions themselves keep their fine quality throughout this period if you follow our recommended moisture routines.
Unlike Tape Hair, which is attached in wider sections, Nail Hair uses small round bonds that allow maximum movement. This makes it easier to wear your hair in tight, high ponytails without the bonds showing.
Before going to bed, it's important to brush through all your hair thoroughly from root to tip. Then braid it into one or two loose braids to minimise wear and tangles overnight.
