Hi guys ..... you`re better off just applying / bonding your system to your skin only ,not onto growing hair. This gives a seamless/ undetectable join, to the touch. If you use a strong glue or tape and part of it is stuck to your [growing] hair it can literally be a pain when removing as you will tend to tear hair out by the roots -- it can be painful enough when the short stubbly hairs grow beneath the bond and the system has not been de-bonded for a while--you go to remove it and it can bring a tear to the eye !! When I used to wear all -poly and went to the salon, the bond would be in place for 3 /4 weeks and in winter [cold]weather the glue would still be very strong --boy did that hurt --almost felt like a layer of scalp was being peeled off !!
