What Are The Causes Of Hair Thinning In Males?

Hair loss and thinning of hair is a common phenomenon, affecting millions of men across the world. According to the American Hair Loss Association, by the time they 35, 66% of men in America experience some level of hair loss, and by 50, nearly 85% of men face significant hair thinning.

Thinning hair can be linked to several reasons, including diet, vitamin and nutrient deficiencies, hormones, family history, stress, age, and so on. However, maximum hair thinning cases can be attributed to androgenetic alopecia or male pattern baldness.

To figure out the appropriate hair fall treatment, it is imperative to determine whether the hair thinning is being caused as a result of genes or it is due to any other reason.

Main causes of hair thinning in males:

  • Male pattern baldness
    Androgenetic alopecia or male pattern baldness annually affects a staggering 50 million men in the US. The hair thinning in this condition begins in a well-defined pattern, starting above the temples and, over time, receding to form an “M” shape. One of the chief causes of male pattern baldness is genes or having a history of baldness in the family. Male pattern baldness can also occur as a result of age or hormones.
  • Hormones
    DHT or dihydrotestosterone is the hormone responsible for androgenetic hair loss in men. DHT is essentially an androgen or a sex hormone, which is derived from testosterone. When the body starts producing increased levels of androgens, including DHT, the lifespan of the hair follicles gets shortened. DHT attacks the hair follicles on the scalp, binding the receptors in the follicles, thereby causing them to shrink, weaken, and ultimately die.
  • Diet and nutrient deficiencies
    What you eat has more impact on your hair health than you think. Nutrients, vitamins, proteins, and minerals are highly essential in order to boost the growth cycle of the follicles. Therefore, to ensure that your scalp is getting the nutrients and nourishment it needs, follow a diet rich in minerals, antioxidants, and vitamins. Include plenty of foods like nuts, fruits, fish, eggs, and green vegetables in your diet.
  • Medical conditions
    Certain medical conditions such as thyroid, lupus, anemia, and diabetes can cause hair thinning or hair loss in males. Hair thinning can also occur as a side effect of medicines taken to treat illnesses like high blood pressure, cancer, arthritis, gout, depression, and so on. Cancer treatments like chemotherapy and radiation cause the hair to fall out. However, this generally stops, and your hair grows back gradually after the treatment completes. Infections like ringworm can cause scaly patches and bald areas on the scalp. However, hair growth returns to normal after these infections are treated.
  • Stress
    If you feel your hair is thinning, you may want to check your stress levels. People often experience thinning of hair some months after an emotional or physical shock. This condition is known as telogen effluvium. However, in the majority of cases, the normal volume and density of the hair return once the stressful situations pass.
  • Harsh hair treatments and styling
    Hair thinning can occur due to harsh treatment procedures such as bleaching, straightening, etc. Also, tight hairstyles like ponytails or man-buns can cause the hair to thin out – this condition is known as traction alopecia.


Other than the above causes, risk factors like increasing age, sudden and significant weight loss, poor nutrition, etc., can contribute to an increase in hair loss.
