Sudden hair loss is distressing and is caused by a variety of conditions and problems.
Hair Growth Patterns
The average person has about 100,000 hairs on his head. It is normal to shed 50 or more hairs a day. Hair grows in cycles. A strand of hair can usually live three years before it falls out. Once a hair falls out, the hair follicle begins to grow a new hair. If you start losing hair faster than usual and the follicle does not produce another hair to replace it, you will end up with bald spots.
The autoimmune disease Alopecia Areata results in hair loss. You will lose the hair all over your body.
Hair loss due to Telogen Effluvium is caused by emotional or physical shock or stress. The hair follicle pushes the hair out of the head early, but usually a new hair will grow back within a month or two.
Traction Alopecia is when a hairstyle pulls your hair too tightly and causes the hair to fall out in that area.
Male Pattern Baldness
Male pattern baldness is a common occurrence in men. It is a hereditary condition.
Other Reasons For Baldness
Other reasons for sudden hair loss are: poor nutrition, certain medications, diabetes, lupus, chemotherapy, radiation, childbirth, menopause, hormonal changes, street drugs, thyroid disorders and mental illness.
