Hair system ridges/creases at the back when applying it,using tape.

[DarkStranger]

How do you totally avoid getting a ridge/crease in the hair system when applying it?

I apply it from the front to the back. Rolled back to the back,with a slight bit of tension so it doesn't go on too loosely.
However it's always the back that gets the creases. It's not seen, but feels awful like a flap of the base stuck together if touched after.

The base is a full French lace base.
