What is the Difference Between Hair Loss and Hair Shedding?

Hair concerns are common among individuals of all ages, with many expressing worries about the health and appearance of their hair. Two terms frequently discussed in this context are hair shedding and hair loss. While these terms may sound similar—and are often used interchangeably—they refer to distinct phenomena with different implications for hair health.

Understanding the distinction between normal hair shedding and significant hair loss is essential for identifying potential underlying causes and determining when it may be necessary to seek professional guidance.

The Hair Growth Cycle

But before diving into the differences between hair shedding and hair loss, it is vital to first understand the hair growth cycle. This cycle consists of several distinct phases, each playing a crucial role in the overall health and appearance of hair. 

1. Anagen Phase (Growth Phase): The anagen phase represents the active growth stage of hair, typically lasting between 2 to 8 years—varying substantially based on individual genetics and ethnic backgrounds. During this time, hair grows approximately 1 to 2 centimetres per month. Subsequently, around 90% of hair follicles are in the anagen phase at any time, actively producing new hair strands.
2. Catagen Phase (Transitional Phase): Following the anagen phase is the catagen phase, a brief transitional stage that lasts about 2 to 4 weeks. During this time, hair growth slows down significantly as the hair follicles shrink and detach from their blood supply. This process creates what is known as "club hair," a non-growing hair that stays in place until it eventually sheds. At any given moment, only 3% of hairs are in the catagen phase.  
3. Telogen Phase (Resting Phase): The telogen phase is the resting stage of the hair growth cycle, lasting approximately 3 to 4 months. During this phase, hair is not actively growing; instead, it prepares to shed as new strands begin to emerge from the follicle.
4. Exogen Phase (Shedding Phase): The exogen phase, often overlooked as a separate stage, specifically refers to the process of hair shedding. While this shedding can occur at various points throughout the hair cycle, it is most frequently observed during the telogen phase.

Normal Hair Shedding

Hair shedding is a natural aspect of the hair growth cycle, with individuals typically shedding 50 to 100 hairs each day. This process is typically balanced by an equivalent amount of new hair growth, which helps to maintain overall hair density.

Several factors can contribute to normal hair shedding, such as:

• seasonal changes
• stressors (e.g., temporary stress, illness, or emotional strain)
• hormonal fluctuations, often linked to pregnancy, childbirth, menopause, or thyroid problems

These factors can temporarily disrupt the balance between shedding and regrowth, but in most cases, the hair cycle eventually stabilises.

Hair Loss

Hair loss is characterised by a substantial and often persistent decrease in hair density. Unlike normal shedding, which is temporary, hair loss may result in thinning, bald patches, or complete loss in certain areas.

Here are some of the most common types of hair loss:

• Androgenetic Alopecia (Pattern Baldness) – A genetic condition that causes hair loss in both men and women. It is characterised by a gradual thinning and hairline recession in men and diffuse thinning from the crown in women. 
• Telogen Effluvium – A temporary form of hair loss triggered by stress, illness, or certain medications. Although it can be concerning, telogen effluvium usually resolves on its own within a few months. 
• Alopecia Areata – An autoimmune disorder that causes sudden patches of baldness. The exact cause is still unclear, but it is believed to be related to the immune system mistakenly attacking hair follicles. 
• Scarring Alopecia – This type of hair loss is permanent and occurs due to injury, burns, or certain medical conditions that damage the hair follicle, preventing future hair growth.

Hair Shedding and Hair Loss—Key Differences

While hair shedding and hair loss may appear similar, several key distinctions can help individuals more accurately identify their condition. The following table summarises the main differences:

	Hair Shedding	Hair Loss
Definition	Natural process	Significant decrease in density
Pattern	Occurs evenly across the scalp	Follows specific patterns, such as receding hairlines or thinning at the crown
Daily Rate	50 to 100 hairs	More than 100 hairs
Duration	Temporary	Can be permanent
Causes	Stress, hormonal changes	Genetics, medical conditions
Treatment	Usually not needed	May require medical intervention

 

Individuals experiencing hair loss may also notice accompanying symptoms, such as:

• Scalp Discomfort: Itching, burning sensations, or tenderness may occur alongside hair loss.
• Pattern Changes: This can include gradual widening of the part, receding hairline, or noticeable thinning.

When to Seek Professional Help

Individuals who notice excessive daily shedding or signs of thinning or bald patches should consider consulting a professional. Persistent or progressive symptoms often indicate underlying issues that require medical evaluation.

Timely diagnosis and intervention play a vital role in successfully managing hair loss. Through a thorough examination, a dermatologist can identify the type of hair loss and recommend appropriate treatments. This may include topical applications, oral medications, or specialised therapies designed to address the underlying cause.
