HAIR LOSS AND THE CAUSES:
QUESTION: What is the normal cycle of hair growth and loss?
ANSWER: The normal cycle of hair growth lasts from 2 to 8 years and you will lose between 70 to 160 hairs per day.
EXPLANATION: Each hair on your head will grow for its predetermined growth cycle. An indicator of a 5.5 year hair cycle is that you have managed to grow your hair to reach the middle of your back at some time in your life.
Those who could never grow their hair longer than shoulders, have a shorter hair cycle of 2-3 years. Long hair that grows past waist length has a hair cycle of 7-8 years.
Your hair cycle length is part of you and cannot be changed. Each hair on your head has the same growth cycle.
Each hair grows approximately 1 centimeter per month. About 90 percent of the hair on your scalp is growing at any one time.
About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 3 to 4 months, the resting hair falls out and new hair starts to grow in its place.
It is normal to shed some hair each day as part of this cycle, 70 – 160 hairs per day depending on your individual hair density.
However, some people may experience excessive hair loss (more than 200 hairs per day) over the entire scalp. This is not a patchy type of hair loss nor is it localized or has a ‘typical’ pattern.
Hair loss of this type is termed “Diffuse Hair Loss”
