6 Perfectly Normal Reasons You Might Be Losing Hair

Brushing Hair

Thinning hair and hair loss are not just common in men, but also in women. The reasons can range from a physical cause to an emotional cause, a vitamin deficiency or an underlying health condition. There are many ways to treat hair loss and in most cases, the loss is only temporary.

Physical Stress

Any kind of physical stress, whether it’s because of the flu, a car accident, or a surgery, can cause a temporary hair loss called telogen effluvium. Hair has a life cycle that involves three phases: growth, rest, and shedding. Marc Glashofer, a dermatologist, says that a stressful event can shock hair and push it into the shedding phase. Hair loss usually becomes noticeable three to six months after the trauma and will start to grow back afterwards.


Glashofer likened pregnancy to a traumatic event as it is one example of a physical stress that can cause hair loss. Pregnancy-related hair loss is often seen after the baby has been delivered rather than during the pregnancy. This is normal and you can rest assured that your hair will grow back.

Too Much Vitamin A

According to the American Academy of Dermatology, overdosing on vitamin A supplements or medications can cause hair loss. Adults and children over age 4 should not be taking more than 5,000 IU per day. This is a reversible cause for hair loss; hair should go back to growing normally once the extra dosage has halted.

Not Enough Protein

If you’re not getting enough protein in your diet, your body may try to compensate by shutting down hair growth. This can occur two to three months after a declined protein intake. If you think this may be why you’ve been losing hair, try eating more fish, meat, and eggs.

Female Hormones

Just as the hormones during pregnancy can cause hair loss, so can switching or going off birth control pills. This can also cause telogen effluvium and losing hair may be more likely if you or your family have a history of hair loss. The hormonal imbalance that happens during menopause may also cause hair loss. Speak to your doctor about hair loss due to birth control pills; luckily this loss is temporary.

Emotional Stress

Emotional stress is less likely to cause hair loss than physical stress, but sometimes in the case of a divorce, the death of a loved one, or caring for an aging parent can bring it on. This is also a temporary hair loss; your hair should start growing normally once you’ve exited such a stressful state of mind.
