Can you see I have a hair extension?

As a rule, a minimum hair length of 8-10 cm is required for a hair extension. But it also depends on your hair density. That means, if you have very, very thin hair or even hair loss, we advise against hair extension and recommend hair thickening with tape or clip-ins.
If a hair extension is well done and also of high quality, nobody can see the bondings, tape joints or clips. And the magic of your hair remains secret...
