At the end of the resting period, your old hairs are shed and new hair replaces them as the growth cycle starts.
The majority of your scalp follicles are growing hair at the same time, but the rate of growth can be affected by your health, your age, and your stress levels.
It is normal to lose some hair every day. The average adult has over 100,000 strands of hair on their scalp and it is common to lose around 80 – 100 strands a day, this number is based on the natural density or thickness of the head of hair.
Don’t worry about some hair loss, unless it is excessive or you begin to notice that your hair looks noticeably thinner.
Hair Shedding from Stress
Telogen effluvium hair is a condition with the tongue-twisting name is directly linked to a serious one-time stressful event such as surgery, injury, or sickness. This condition is a very common cause of large amounts of hair falling out.
Telogen effluvium is a slowing of new hair growth resulting from sudden severe emotional, physical, or hormonal stress, followed after a delay of about 2 months by the shedding of hair, sometimes in alarming amounts.
With telogen effluvium, the stressful event induces a higher proportion of hair follicles to enter the resting stage all at the same time.
A few months later, after the stressful event, all of the now-resting follicles begin to shed their hairs at about the same time.
Because the stressful event happened months ago, most people do not connect it with their hair loss.
