How to Find Out Why Your Hair Keeps Falling Out

A little bit of hair loss is part of your hair's normal growth and shedding process, but when you lose large amounts of hair over a prolonged period of time, it could mean you have an underlying health condition. It's important to see your doctor to help determine if your hair loss is caused by a treatable condition. Often, with treatment, you can stop the loss and spur new growth.

Step 1

Discuss your other symptoms with a doctor. Tell her every detail, even if it seems minor. For example, seemingly insignificant side effects of thyroid disease include dry skin or brittle fingernails and hair loss. Consider an evaluation for diseases such as diabetes or lupus, which can lead to hair loss, according to the Mayo Clinic.

Step 2

Determine through a blood test if you have a B vitamin deficiency. According to the American Cancer Society, B vitamins are essential for hair growth. A lack of B vitamins can cause hair loss.

Step 3

Test your hormone levels. FamilyDoctor.org points out that hormonal changes after pregnancy or during menopause can lead to hair loss. This is also true for women who have hormone imbalances. Ask specifically for your androgen levels because these directly affect body hair.

Step 4

Talk to your doctor about medications you're taking. Some medications cause hair loss. According to FamilyDoctor.org, blood thinners, blood pressure medications, birth control pills and antidepressants can cause hair loss.

Step 5

Ask your doctor or dermatologist to evaluate your scalp. Fungal and bacterial scalp infections can cause hair loss, according to the Mayo Clinic. Discuss the possibility of alopecia or male pattern baldness.
