they say you are spose to loose AT LEAST 100 hairs a day.... I am only 21 and i constantly loose alot of hair in the bath and shower and then when I get out and brush my wet hair there will be at least a handful of hair pulled out of my brush just from brushing it that one time. Its normal for hair to fall it what you need to worry about is if its coming from one area or your hair is thinning to the point others may notice then you may worry about it but different people tend to loose alot more hair then others and women loose more hair then men i think...hope this helped
