What Are the Causes of Hair Loss?


We lose bits of hair every day, but excessive hair loss can be a little scary.

When we run our hands through our hair or comb through it, we typically lose a bit of hair. On an average, we lose 50-100 strands a day. This is how the hair cycle works, and there will be new hairs to replace the ones that are lost.

However, it’s also common for people to experience excessive hair loss. If you’re experiencing this kind of hair loss, here are some of the reasons that could be behind it:

         Male-pattern / Female-pattern baldness

Hormones come into play in male- / female-pattern baldness. This is the most common cause of baldness where certain sex hormones and genetics cause a pattern of hair loss. Meaning, if baldness runs in your family, you could experience it too. This type is more common in men, where thinning hair can be noticed as early as puberty.

         Hormonal changes / Imbalance

This applies to women in particular, like if they’re pregnant or have just given birth. Hair loss can also be a sign of the onset of menopause. Also, some may experience hair loss if they suddenly stop taking birth control pills.

         Medical conditions

There are several medical conditions that could cause hair loss. If you have thyroid problems, for example, and the thyroid gland isn’t functioning properly, hair loss can occur. Scalp infections, too, can cause hair loss. Certain skin disorders like lichen planus and certain types of lupus can cause permanent hair loss where the scars appear.


There are some cases where drugs used to treat certain conditions result in hair loss. Some of these include drugs used to treat depression, arthritis, cancer, heart problems and high blood pressure.

          Physical or emotional shock

Going through a highly emotional experience can cause hair to thin for several months after. Some of these experiences include a high fever, a death in the family, or sudden or excessive weight loss.

If your hair loss is a cause for concern, talk to your doctor or a trusted hair loss expert. Be sure to take note of details like your family and medical history and recent life changes before you make your appointment.
