This type of hair loss involves a disruption in the normal growth cycle of scalp hair. Hair grows in a repeating cycle of stages. These include anagen (the growth stage) and telogen (a period of rest). If you're in general good health, up to 90% of your scalp hair will be in anagen at any one time. The other 10% is usually in telogen. This hair then falls out after a few months and this natural cycle restarts. What all this basically amounts to, is that everyone loses about 100 hairs per day as part of the normal growth cycle of hair. Find out more:

There are many things that can cause this type of hair loss:
Just as there are many causes of this condition, there are various types too:
Note: These variations should not be confused with anagen effluvium - this is sudden hair loss due to chemotherapy (chemical treatment) or radiation treatment. Chronic Telogen Effluvium (CTE) This can be a very long-term, persistent form of hair loss. It's caused by an iron deficiency, and can affect both men and women. CTE is evenly distributed hair loss (diffuse thinning) across the entire scalp. This means that it's not patchy (like alopecia areata) or restricted to the crown of the head - as in alopecia androgenetica (see below).
Since it affects the whole scalp, CTE might not be obvious to anyone else except you. Women often notice CTE by having less hair available to clip or tie up in a ponytail. There will also be more hair left in brushes and the sink after washing.
The richest source of dietary iron comes from red meat. So, it's possible that a vegetarian diet (or one that lacks red meat) can also lead to CTE. Blood tests can help identify CTE (especially in women - a low serum ferritin level will usually result from menstruation blood loss).
Chronic Telogen Effluvium Treatment If an iron deficiency is corrected, and the serum ferritin level raised to a certain point, then hair growth will restart. So, can you eat your way to a full head of hair? Eating a large portion of red meat everyday would definately raise iron levels. But this is not really a practical option for most people. A high strength iron supplement is the quickest way to increase ferritin levels (but even this will take about 6 months to achieve). Also, even a high dose iron supplement with additional vitamin C (which helps iron absorption) might not be enough to raise ferritin levels in many cases. Learn about Nutrihair (Florisene) and other

for CTE. This condition involves a sudden increase in hair loss 2 to 5 months after a seriously traumatic event takes place. In acute telogen effluvium hair loss, as much as 70% of the scalp hair can be forced into the telogen (resting) stage, and then start to fall. This rapid form of hair loss could be caused in many ways including physical trauma (e.g., major surgery) or a radical change to your diet: Severe calorie restriction (crash diets or those providing less than 1200 calories per day) can place the body under stress and trigger acute telogen effluvium. If it receives insufficient nutrients (especially protein) the human body can react by shutting down hair production - protein will be saved if healthy hairs are shifted into telogen. (This is just one way in which the body can redirect energy and so help conserve its essential organs). Note: Don't confuse Acute telogen effluvium with alopecia areata which can similarly cause rapid hair loss. During pregnancy, there's a big rise in female hormone levels (oestrogen and progesterone). This causes an increased percentage of scalp hairs to stay in the anagen growth phase (and often makes a womans hair seem much more thick and glossy). But, immediately after giving birth, there is a corresponding fall in the levels of these hormones. This throws the normal hair growth cycle temporarily out of sync, and more hair than usual enters the telogen stage. As a result, 1 to 5 months after giving birth, hair can start to fall out dramatically - much more hair will be found in the hairbrush, the sink plughole, and even in the fists of the newborn child! This human moult condition will occur in approximately 50% of all women after childbirth, but normally corrects itself within a year - more and more follicles gradually reverting back into the anagen growth stage. However, it can last much longer if you have a genetic tendency towards hair loss (alopecia androgenetica) or have the skin disease alopecia areata. Long term telogen effluvium like this requires a medical evaluation to rule out other forms of hair loss or metabolic conditions. Many women connect their hair loss to breastfeeding by mistake. That's because both events may begin some months after giving birth. However, this is merely coincidence - breastfeeding does not cause hair loss. Note: Don't confuse post partum telogen effluvium with post partum thyroiditis - This condition develops in about 10% of women 6 to 12 months after they've given birth. Learn more about
post partum thyroiditis.
First of all, if any type of hair loss be persistant or severe, you should see a qualified dermatologist to help effectively diagnose it.
