How to trim my first Super thin skin Hair system

[mrmyhair]

Hi All,
I just got my first super thin skin hair system (.03mm)
It has some very fine skin around the front hairline... How much of it are you supposed to trim? Right up to the hairline or a bit below?? Also whats the best way to trim it?

Thanks,

I usually go to the hairline
