It is completely normal for everyone to lose hair on a daily basis as the hair follicles go through their normal growth cycle that is made up of three stages: the anagen phase (growth phase), catagen phase (shedding phase), and telogen phase (resting phase). But when should you be concerned about temporary hair loss?
A full hair growth cycle will in most cases take years to complete. Every hair follicle goes through the complete cycle at least 10 to 20 times throughout a normal human lifespan. In most cases, roughly 1% or less of the hair follicles that are located on the scalp are in their shedding phase, which happens when the new telogen (growth) phase starts.
The average number of hairs lost every day that is considered a normal amount is somewhere between 60 and 100 hairs. If you are noticing that you are losing more than 100 hairs per day, it may indicate an abnormal shift in your hair growth cycle. Each hair follicle is an independent unit. It is not working in coordination with the neighbouring follicles, but is responding to the same growth pattern signals that the other follicles are responding to.
