Differentiating Abnormal Hair Fall from Normal Hair Shedding and Understanding the Causes of Excessive Hair Loss

Normal Hair Shedding

On average, it is normal to lose between 50 to 100 hairs per day. This is a natural part of the hair growth cycle, which consists of three phases:

1. Anagen phase: The active growth phase where hair follicles produce new hair.

2. Catagen phase: A transitional phase where hair growth slows down.

3. Telogen phase: The resting phase where old hairs are shed to make room for new hair growth.

During the telogen phase, hair follicles naturally release the old hair strands, leading to normal daily shedding. This shedding is typically evenly distributed across the scalp and is not accompanied by any noticeable thinning or bald patches.

Abnormal Hair Fall

Abnormal or excessive hair fall refers to a higher rate of hair loss than what is considered normal. It may be characterized by:

• Increased shedding: Losing more than 100 hairs per day.

• Thinning hair: Noticeable reduction in hair density or visible scalp.

• Bald patches: Clearly defined areas of hair loss.

• Changes in hair texture: Brittle, dry, or easily breakable hair.

There can be several reasons for abnormal hair fall, including:

1. Genetic Factors

Family history plays a significant role in hair loss. Conditions such as male pattern baldness and female pattern hair loss are inherited and can lead to progressive hair thinning and eventual hair loss.

2. Hormonal Imbalances

Hormonal changes due to pregnancy, childbirth, menopause, or thyroid disorders can disrupt the hair growth cycle and result in excessive hair fall.

3. Nutritional Deficiencies

Inadequate intake of essential nutrients like vitamins (especially vitamin D and B vitamins), minerals (such as iron and zinc), and proteins can weaken hair follicles and lead to increased hair shedding.

4. Medical Conditions

Underlying medical conditions like scalp infections, autoimmune disorders (such as alopecia areata), and certain skin conditions (like psoriasis) can cause abnormal hair fall.

5. Medications and Treatments

Certain medications, such as chemotherapy drugs, anticoagulants, and antidepressants, can cause hair loss as a side effect. Additionally, excessive hairstyling, chemical treatments, and heat damage can weaken hair strands and contribute to hair fall.

6. Emotional and Physical Stress

Stressful events, trauma, or prolonged emotional and physical stress can disrupt the hair growth cycle, leading to excessive shedding.

Conclusion

Distinguishing between normal hair shedding and abnormal hair fall is crucial in identifying potential causes and seeking appropriate treatment. If you suspect that you are experiencing abnormal hair fall, it is advisable to consult a dermatologist or a healthcare professional who specializes in hair disorders. They can evaluate your condition, determine the underlying causes, and recommend suitable treatment options to address excessive hair loss.
