How many hair falling out can lead to baldness?

Hair loss of 100 hairs per day is normal. But, it is very difficult to gauge when this limit of 100 hairs is crossed. Here are 7 warning signs when you should consult your dermatologist:

  • Bunch of hair while combing or shampooing your hair.
  • Hair on your pillow, beddings or floor.
  • Thinner and smaller hair strands.
  • Visible bald scalp.
  • Receding of the frontal hairline in males. You might notice broadening of the forehead. Your barber might prompt loss of hair on your vertex while doing hair cut.
  • In females, widening of central parting and reduction in the volume of the ponytail.
  • Positive hair pull test: Pull a bunch of approximately 100 hair using moderate pressure. If you get more than 6 hair, then it is an indicator that you are having active hair fall. Dr Surbhi, MD has shown hair pull test in the end of this video:

Type of hair loss

There are 4 major types of hair loss- patchy, diffuse, male pattern and female pattern as shown in this video:

Causes hair loss

The cause of hair loss depends of the types of hair loss. We have listed the reason of each type below:

Telogen Effluvium (or diffuse hair loss)

Telogen effluvium is most common cause of hair loss in female. Watch this video to know more:

Following are the common causes of diffuse hair fall:

Acute stress:

Physical or mental stress that mandates you to take bed rest can result in hair loss. For example high-grade fevers (typhoid, malaria, etc.), major surgery, severe trauma, bereavement etc.


You might get hair loss after 3 months of Covid, even if mild.


Chronic illness:

Any chronic medical disease can result in hair loss. For example cancers, chronic kidney or liver diseases, tuberculosis etc.

Hormonal factors:

Hormones are important in maintaining hair cycle. Hypo/hyperthyroidism, polycystic ovarian diseases (PCOD), discontinuation of oral contraceptive pills and delivery can cause hair loss.

Hormonal cause should be suspected in following situations:

  • change in your menstrual cycles
  • weight gain
  • pimples on the jaw line or near your menses
  • thick dark hair on the face

Post-Partum hair loss:

Diffuse hair loss in mother and baby is common 3-6 months post-delivery and it usually stops in a few months. To know more, click postpartum hair loss.

Dietary deficiencies:

Hair loss can occur if you are not taking enough proteins, vitamins, minerals etc.


Your hair loss could be due to medicines for high blood pressure, thyroid disorders, psychiatric diseases, hormonal imbalance etc.

Mental stress:

Normal day stress is unlikely to cause hair loss. Undue stress like bereavement, loss of a job, depression etc. can cause hair fall.

Without any reason or Idiopathic:

In females at the age of 30-60 years sudden shedding and thinning of hair occur without any reason. You may have hair shedding all over the scalp, especially temporal area.


In my experience, nutrition or hormone are common cause of Diffuse hair loss.


Male Pattern Hair Loss:

Male pattern baldness or Androgenetic Alopecia presents with receding frontal hairline and hair loss from the vertex as shown below:


It is caused by genetic tendency, which can be transmitted from both mother anf father side.

Female Pattern Hair Loss:

In Female pattern Baldness, hair fall from the centre of head leading to widening the central parting. The bald area looks like a Christmas tree. Watch the video to know more:


This type of hair loss is because of genes or PCOD.  You might have a family member with a similar type of hair loss.
