I want to know the exact reason on why human's hair will fall off? Some of the common reason will be due to stress, tiredness etc.
Is there any context to show what actually caused the hair to fall off? How does the falling of hair actually happens?
Hope I make sense...
here are a few facts about hair/hair loss: Hair loss affects everyone on some level despite race, gender, or stress level. In other words, we all shed like bears so don't feel that the problem is individual. Secondly, hair goes through three stages of devolopment: Anagen, Catagen and Telogen. the first stage, Anagen lasts around two to eight years. In this stage the hair will push through your hair follicle and into your pore, and at this time the hair follicle grows deeper and deeper into your "dermis",
a.k.a. your skin. Catagen: This stage lasts around 2-4 weeks. At this point your hair has started to disconnect from your blood flow and begins to loosen. The hair follicle (which is basically the root of your hair) then discintegrates and pushes your hair up. Telogen: This phase lasts around 2-4 months . during this phase, the hair is still disconnected from bloodflow and doesn't grow. After this phase ends, a new hair begins to sprout from the hair follicle, thus pushing the old hair out, much like the way our adult teeth push our milk teeth out. after this the cycle repeats on and on. Keep in mind that shedding is a very good thing, because it means that in most cases, new hair is coming, but actual hair loss is a very different thing.
I know this info is slightly off topic, because it explains more about shedding, not hair loss, but to tell you the truth my friend, hair loss is still being debated about. the most accepted theory is that it is related to hormones. I hope i was of some help to you for understanding shedding and hair loss.
By the way, here are some pics to help explain everything:
