Causes of Hair Loss
We all lose 50 to 100 hairs a day (on average), but because new hair is always growing at the same time, it isn’t usually noticeable. When new hair is no longer growing back in to replace the hair being lost, it’s cause for concern.
Hair loss is usually related to one or more of the following factors:
Hormonal changes, such as low testosterone levels. This occurs gradually and in predictable patterns, like those seen in a receding hairline or bald spots. When testosterone levels decline, the normal cycle of hair growth changes. Some hair will begin to grow in shorter and thinner, and in some spots, growth may stop altogether.
Heredity:
The most common cause of thinning hair is family history. It is a natural condition caused by some combination of aging, low testosterone levels, and genetics (a family history of baldness on the mother’s side of the family).
Medications. Some drugs like antidepressants, birth control pills, acne medications and immunosuppressants are thought to cause hair loss.
Stress:
Physical or emotional trauma can cause hair to fall out.
Hairstyles:
A hairstyle that pulls the hair tight (like cornrows and extensions) can cause unnecessary hair loss.
Other factors that may increase your risk of hair loss include age, significant weight loss, diabetes, lupus and other autoimmune conditions, thyroid conditions, and poor nutrition.
