Hair loss is a common phenomenon that affects both men and women. It can be due to various factors ranging from genetic factors to certain medical conditions. Hair loss can lead to baldness or thinning of hair, which can significantly impact a person’s self-esteem and confidence.

In this article, our experts in PRP hair restoration will discuss the various causes of hair loss in adults.

Genetic Factors

Genetic factors play a significant role in hair loss. Androgenetic alopecia, or male/female pattern baldness, is a genetic condition that causes hair loss in both men and women. This condition is caused by a combination of genetics, hormones, and age. Men with male pattern baldness usually have a receding hairline. In contrast, women with female baldness typically experience hair thinning on the top of their heads.

Medical Conditions

Some medical conditions can cause hair loss in adults. Some of the most common medical conditions that cause hair loss include:

  • Thyroid disorders: An overactive or underactive thyroid gland can cause hair loss.
  • Alopecia areata: This autoimmune condition causes hair loss in patches.
  • Scalp infections: Fungal infections, bacterial infections, and other scalp infections can cause hair loss.
  • Iron deficiency anemia: Iron deficiency can lead to hair loss.
  • Trichotillomania: This is a psychological disorder characterized by the urge to pull out one’s hair.
  • Lupus: Lupus is an autoimmune condition that can cause hair loss.
  • Polycystic ovary syndrome (PCOS): PCOS can cause hormonal imbalances that may lead to hair loss.
  • Telogen effluvium: This causes hair to fall out in large quantities due to stress, illness, or surgery.


Some medications can also cause hair loss as a side effect. Some of the medications that can cause hair loss include:

  • Chemotherapy drugs: These drugs are used to treat cancer and can cause hair loss.
  • Blood thinners: Anticoagulants such as warfarin can cause hair loss.
  • Acne medications: Some acne medications, such as isotretinoin, can cause hair loss.
  • Antidepressants: Some antidepressants can cause hair loss.
  • Steroids: Steroids can cause hair loss as a side effect.
  • Birth control pills: Some birth control pills can cause hair loss.
  • Immunosuppressants: Immunosuppressants such as cyclosporine can cause hair loss.

Poor Nutrition

Poor nutrition can also cause hair loss. A diet lacking nutrients, vitamins, and minerals can result in hair loss. Some of the essential nutrients that are necessary for healthy hair growth include:

  • Vitamin A: This vitamin is essential for the growth and maintenance of healthy hair.
  • B vitamins: B vitamins such as biotin and niacin are essential for healthy hair growth.
  • Vitamin C: This vitamin is essential for collagen production, which is necessary for healthy hair growth.
  • Vitamin D: This vitamin is essential for the growth and maintenance of healthy hair.
  • Iron: Iron is necessary for healthy hair growth.
  • Zinc: Zinc is essential for healthy hair growth.


Stress can also cause hair loss. Stress can lead to hormonal imbalances that affect hair growth. Stress can also cause a condition called telogen effluvium, which causes hair to fall out in large quantities.


Hair loss may be a common condition, but it can have a huge impact on one’s self-esteem and confidence. The causes of hair loss in adults can be genetic, medical, or due to poor nutrition, or stress. If you are or a loved one is experiencing hair loss, it is essential to consult a doctor to determine the underlying cause and to discuss treatment options like PRP hair restoration.
