Illegal Equipment Question

[PIAA REF]

I can find caseplay or rule references about Jewlry and not tucking shirt in and making a player have to leave the game for a tick of the clock. What about these: Bobypin, illegal headband, wristband ect.

Do you make them leave the game if not noticed or do you just let them rectify the situation quickly and play? If you have a rule to reference please let me know, thanks.

Play situation: A1 is at free-throw line ready to attempt free-throws. Ref at this time sees that the shooter has bobypins, or an illegal wristband. Ref clears lane, allows shooter to shoot and then has player replaced for having illegal equipment. Was ref correct?
