Hair loss is part of the hair growth cycle, it is normal to lose between 50 and 100 hair strands per day.  It is impossible to count the number of hair loss in a day. But if you notice a large amount of hair in the drain after washing or on your brush you should consult a dermatologist. There may be multiple causes for your hair loss, a few of them are mentioned below. 

Common causes of hair loss

  • Family history (heredity): If you have a family history of hair loss, you are more likely to experience it, as well.
  • Age: With age, hair growth slows down, and causes thinning of hair
  • Hormonal changes: Pregnancy, childbirth, menopause and thyroid problems can cause hair loss.
  • Medical conditions: Scalp psoriasis or infections such as ringworm can also lead to hair loss.
  • Medications: Hair loss can also occur due to medications used for the treatment of cancer, high blood pressure, depression, heart problems or arthritis. 
  • Stress: Physical (illness, operation, accident or extreme weight loss) or emotional shock may also trigger hair loss.
  • Hairstyles and treatments: Excessive hairstyling like colour, perming, straightening or hot-oil treatment can cause hair to fall. Certain hairstyles that pull your hair tight can also lead to hair loss.
  • Nutritional deficiencies: If you are not taking enough biotin, iron, zinc or protein in your diet, you may experience hair loss.


Depending on the cause of hair loss, your dermatologist will decide the appropriate treatment plan. For example, if an underlying disease is a cause of your hair loss, treating the disease is necessary. In certain cases, one or more medications may be started.

These medications may slow the rate of hair loss or help regrow the hair or both. It will take at least six months of treatment to prevent further hair loss and to show hair regrowth. In the early stages of application, certain medications can cause the existing hairs to fall out. Do not panic, this is a normal phenomenon. This makes way for the new hair to grow. Continue using the medication, do not stop it without consulting your dermatologist. But if you face a lot of hair shedding, consult your dermatologist immediately.

If the medication is helping, you will need to continue using the medicine every day to retain the benefits. Once you stop applying it, hair loss may return.
