The average typical loss of hair amounts to about 100 strands a day. And the average human head has about 100,000 hair follicles. Each one of these follicles can grow about 20 individual hairs during a person’s lifetime. Female or male pattern baldness varies from population to population based on genetic background. It’s important to understand the cause of your hair loss before you undergo any hair loss remedy or treatment.
Some drugs or medications can actually cause hair loss, which improves when you stop taking the medicine. Medications that can cause hair loss include the blood thinners, medicines used for gout and gouty arthritis, chemotherapy drugs used for cancer, too much vitamin A supplementation, birth control pills and antidepressants. Hypothyroidism can cause it, especially the thinning of the outer third of the eyebrows. Many women notice hair loss about three months after they’ve had a baby. During pregnancy, high levels of certain hormones cause the body to keep hair that would normally fall out. So when the hormones return to pre-pregnancy levels that hair falls out and the normal cycle of growth and loss starts up all over again.
