While vysean's experience (three rooms with hairs) suggests there may be a systemic problem at this hotel, for hotels in general, the hairs may not be a sign of unchanged sheets. I had a problem last year when several guests complained at my property about hairs in the bed in a three day period. I tracked the problem to an employee who was overloading the dryers. Hairs usually come off in the dryer, not the washers, and if the sheets/towels can't tumble properly due to overloading, the air never gets a chance to carry the hairs to the lint trap. I find hairs in the bed unacceptable, even if they have been washed. (I don't want to sleep on somebody else's hair, even if they are clean hairs!)

Housekeeping should have seen the hairs on "clean" sheets and remedied the situation. All of my maid carts have a lint roller for this reason.

Seems to me that when so many FT'ers find hairs at one property, they need to review their housekeeping program. I would suspect they may have indeed left 'dirty' sheets on the beds to begin with. We count our sheets- if housekeeping doesn't turn in enough dirty ones for the rooms they claim to have cleaned, a supervisor checks every bed to find out why. Most times it is because the guest slept on the couch, but twice in the last two years, it was not. No guest was exposed to those dirty sheets because of this policy, but two housekeepers are now working elsewhere.
