We all lose strands of hair naturally throughout the day, sometimes upwards of a hundred a day. It's in your baseball cap, on your pillow, in your shower drain and, yes, in your helmet. If some haircut trimmings in your nutcase give you the heebee-geebees don't even think about all the epidermal cells and perspiration you're leaving there daily...
Which, BTW, is why buying used helmets is grosser than people think
Anyway, if you're really concerned:
- have the hairdresser run the hair dryer while running her fingers through the hair to loosen and expel any stragglers
- have a post-cut hairwash
- go commando (i.e. buzz it all off...)
- man up and just accept that there's all sorts of nasty going on inside your helmet
