Will my partner be able to feel it?
It depends how close you let them get...!
The system is attached where your hair meets your scalp and at this point you will feel tiny "bumps" where the connections are made. However, apart from that both you and your partner will be able to run fingers through your hair etc. without hindrance and both the fibre and your existing hair will look and feel identical.
