Understanding Hair Loss: Causes, Types and When to Seek Treatment
Hair loss is a common condition that affects both men and women at different stages of life. While it is often associated with ageing, hair thinning can begin much earlier and may occur for a variety of reasons including genetics, medical conditions, hormonal changes or stress.
Many people become concerned when they notice increased shedding, thinning hair, or visible patches on the scalp. Understanding the causes of hair loss is the first step in determining whether treatment may be beneficial.
If you are experiencing persistent hair loss in Canberra a medical assessment can help identify the underlying cause and guide appropriate management.
What Is Hair Loss?
Hair loss, medically referred to as alopecia, occurs when hair follicles stop producing new hair or when shedding exceeds normal hair regrowth.
It is normal to lose hair as part of the natural hair growth cycle. On average, the scalp sheds between 50 and 100 hairs per day. In healthy hair growth cycles, new hair replaces the shed strands.
Hair loss occurs when this cycle becomes disrupted and new hair does not grow back at the same rate as it is lost.
Hair loss may develop gradually over time or appear suddenly over a period of days or weeks. Some forms of hair loss are temporary, while others may be permanent if the underlying follicles are damaged.
People may notice hair loss through:
- Gradual thinning of the hair
- A widening part or thinning crown
- Receding hairline
- Patches of missing hair
- Increased hair shedding when brushing or washing
Common Causes of Hair Loss
Hair loss can occur for many reasons. In some cases it is hereditary, while in others it may be triggered by illness, hormonal changes or physical stress.
Common contributing factors include:
- Genetics and family history
- Medical conditions or illness
- Certain medications or medical treatments
- Hormonal changes
- Stress or major life events
- Nutritional deficiencies
- Hairstyles or hair treatments that place tension on the scalp
Identifying the underlying cause is important when considering treatment options.
Types of Hair Loss
There are several medical conditions that can lead to hair loss. Each type has different causes and patterns of hair shedding.
Alopecia Areata
Alopecia areata is an autoimmune condition in which the immune system mistakenly attacks healthy hair follicles. This results in hair falling out in small round patches.
Hair loss can occur suddenly and is usually painless. In some cases, alopecia areata may affect the eyebrows, beard or other body hair.
Anagen Effluvium
Anagen effluvium is a rapid form of hair loss caused by treatments that affect rapidly dividing cells in the body. The most common cause is chemotherapy, which targets cancer cells but also affects hair follicle production.
Hair loss typically occurs quickly during treatment but usually regrows once therapy has been completed.
Androgenetic Alopecia (Pattern Hair Loss)
Androgenetic alopecia is the most common form of hair loss in both men and women. It is often referred to as male pattern baldness or female pattern hair loss and has a strong genetic component.
In men, hair loss often begins with a receding hairline or thinning at the crown of the head. In women, the hairline is usually preserved but the hair gradually thins across the scalp.
Although androgenetic alopecia is hereditary, early treatment may help slow progression and improve hair density.
Cicatricial Alopecia (Scarring Alopecia)
Cicatricial alopecia is a rare form of hair loss caused by inflammation that damages and destroys hair follicles. Scar tissue forms in place of the follicles, preventing new hair from growing.
Because this type of hair loss can lead to permanent damage, early diagnosis by a medical professional is important.
Telogen Effluvium
Telogen effluvium occurs when a large number of hair follicles enter the shedding phase of the hair cycle simultaneously.
It may be triggered by events such as:
- Illness or surgery
- Hormonal changes
- Thyroid disorders
- Childbirth
- Nutritional deficiencies
- Significant physical or emotional stress
People with telogen effluvium may notice increased shedding of 300–500 hairs per day, often resulting in thinning around the crown or temples. In many cases, hair growth returns once the underlying trigger resolves.
Tinea Capitis
Tinea capitis is a fungal infection of the scalp, commonly known as scalp ringworm. It causes scaly patches on the scalp that may lead to areas of hair loss.
This condition is treatable with antifungal medication once diagnosed.
When Should You Seek Medical Advice for Hair Loss?
Hair loss can sometimes resolve on its own, particularly if it is related to temporary stress or illness. However, medical assessment is recommended if you experience:
- Sudden or rapid hair loss
- Patchy hair loss
- Ongoing thinning of the hair
- Scalp redness, scaling or irritation
- Hair loss accompanied by other health symptoms
Early assessment can help identify the cause and determine whether treatment may be helpful.
