How many hairs fall out in a day for a young female?

50-150 per day. Is consider normal hair loss, without causing baldness.. Around 50 to 150 hairs are shed each day and, while there is a wide individual variation, it is important to realise it is the change within the individual that is critical. As long as new hairs are being produced at the same rate as those falling out there will be no difference in hair density or hair shedding.
