As mentioned above, 50 to 100 hairs a day is a normal range of shedding. So if you pull out a few hairs when you rinse out your shampoo or run a brush through your strands, there’s no reason to panic.
Once you begin to lose substantially more hair throughout the day, you may be experiencing excessive shedding. As Garshick says, “Excessive hair shedding may occur as a result of certain physical, emotional, or psychological stressors on the body.”
The shedding generally occurs six to 12 weeks after a distressing event or time period, says consultant trichologist Anabel Kingsly.
