How to Stop Your Hair From Shedding, Once and for All

There are plenty of completely normal reasons why your hair is shedding—in fact, it's part of the hair cycle for hair to fall out. But when you start to notice lots of strands clogging up your shower or coming out when you brush your hair, it can be alarming. 

Trichologist Dominic Burg, chief scientist at Evolis Professional, says that around 100 hairs a day is considered normal. Basically, he explains, hair goes through periods of growth that last about five to seven years, then they chill for a while, and then they fall out. Obviously not every strand of hair is on the same cycle (otherwise we'd all be bald every five years).

"The follicles cycle asynchronously, meaning they each do their own thing in their own time, and this results in about 100 hairs per day entering the falling phase," he says. "This may sound like a lot, but if you compare that to the number of follicles on your head—between 100,000 and 150,000—then you're only shedding 0.001% of your hair each day, and each of these is being replaced by a new hair shaft." 

But when you start noticing a lot more hair in the shower, or your hair comes out easily with just gentle pressure, you may be experiencing excess shedding.  We spoke with Burg and trichologist Michelle Blaisure, Bosley Professional Strength product and technical specialist, to find out why you might be experiencing more hair loss, and how to stop hair shedding.
