Currently not wearing since may.
Have chronic sinusitis and tension headaches now.
I don't know if I will be able to wear again,until that crap is gone.
The salon has my other 2 custom bespoke hair systems I paid for.
Trying again in october 2018.
If still causes me head pressure/headaches then will sadly wait till the new year after I seen the ENT specialists(could be months until I see them) I just don't know anymore.
