Alopecia Symptoms: Early Signs & Warning Signs

Quick Glance: Common Alopecia Symptoms

Alopecia can cause patchy, patterned or widespread hair loss, depending on the underlying condition. Common alopecia symptoms are given below:

Increased hair shedding
Gradual thinning of scalp hair
Round or oval bald patches
A receding hairline
Widening of the hair parting
Thinning around the crown or top of the scalp
Loss of eyebrows, eyelashes or beard hair
Broken or unusually short hairs
Reduced overall hair density
Scalp itching, tenderness or burning in some types

Some forms of alopecia develop gradually over several years, while others can cause noticeable hair loss over weeks or months.

Alopecia Symptoms That Should Not Be Ignored

Hair loss can have many causes. But sudden, rapidly progressive or inflammatory changes deserve medical assessment. The table below lists alopecia symptoms that should not be ignored and what they may indicate:

Symptoms	What They May Indicate
Sudden development of round or oval bald patches	Alopecia areata or another localised cause of hair loss
Rapid or widespread hair shedding	Telogen or anagen effluvium, an underlying illness or another active cause
Hair loss with scalp redness, scaling or crusting	A scalp infection or inflammatory disorder
Scalp pain, burning or marked tenderness with hair loss	Possible inflammatory or scarring alopecia
Smooth or shiny areas with loss of visible follicular openings	Possible permanent follicular damage from scarring alopecia
Loss of eyebrows or eyelashes along with scalp hair	More extensive alopecia or another underlying disorder
Hair loss accompanied by fatigue, weight changes or other unexplained symptoms	A possible nutritional, hormonal or systemic cause
Hair loss that continues to progress without an obvious explanation	A condition requiring assessment to identify the underlying type

Why Do Alopecia Symptoms Occur?

Alopecia symptoms occur because the normal hair growth process is disrupted or the hair follicles are damaged. This can lead to increased shedding, gradual thinning or the development of bald patches.

In some forms of alopecia, more hairs than usual enter the resting and shedding phases. In other forms, the follicles slowly shrink and produce finer, shorter hairs, and gradually reduce hair density over time.

Hair loss can also occur when the immune system targets the follicles or when repeated pulling and tension damage them. In scarring alopecia, ongoing inflammation can permanently destroy the follicles and prevent hair from growing back in the affected areas.

Alopecia Symptoms That Require Immediate Medical Attention

Alopecia is not usually a medical emergency. However, some symptoms require timely assessment as they can lead to permanent follicular damage or indicate an infection or underlying medical condition.

The table below lists serious alopecia-related symptoms and explains why they need attention:

Symptoms	Why They Are Serious
Progressive hair loss with a smooth, shiny scalp and loss of follicular openings	May indicate scarring alopecia, in which follicular damage can become permanent
Hair loss with persistent burning, pain, redness or scaling around follicles	May indicate active inflammatory alopecia that can progressively damage follicles
Painful, boggy or markedly inflamed scalp areas with pustules or discharge	May indicate a significant scalp infection or inflammatory condition that can cause scarring
Rapid widespread hair loss with severe weakness, unexplained weight change or other systemic symptoms	May indicate an underlying medical or nutritional disorder requiring investigation
Rapidly worsening scalp redness or swelling with fever or feeling severely unwell	May indicate a significant infection requiring prompt medical assessment

Symptoms of Alopecia Based on Type

Alopecia is an umbrella term for hair loss rather than a single disease. Different types produce distinct patterns of shedding, thinning or follicular damage.

The table below summarises the typical symptoms of important types of alopecia:

Type of Alopecia	Typical Symptoms
Alopecia areata	Sudden, smooth, round or oval bald patches; short exclamation-mark hairs may occur around the edges, and eyebrows, eyelashes or nails can sometimes be affected
Androgenetic alopecia	Gradual patterned thinning caused by progressive miniaturisation of susceptible hair follicles; the pattern differs between men and women
Telogen effluvium	Increased diffuse shedding from across the scalp, often becoming noticeable a few months after an illness, childbirth, major stress, nutritional problem or another trigger
Anagen effluvium	Rapid, widespread hair loss caused by disruption of actively growing hairs, often occurring relatively soon after significant injury to growing follicles
Traction alopecia	Hair thinning or broken hairs in areas repeatedly exposed to pulling or tension, commonly around the hairline; prolonged traction can eventually cause permanent loss
Scarring alopecia	Progressive and potentially permanent hair loss with possible redness, scaling, itching, burning or tenderness; affected areas may become smooth or shiny as follicular openings disappear

Symptoms of Alopecia-Specific Conditions

Certain recognised alopecia conditions have distinctive patterns that provide additional clues about the extent and location of hair loss.

The table below describes some important alopecia-specific conditions and their typical symptoms:

Condition	Typical Symptoms
Patchy alopecia areata	One or more smooth, clearly defined round or oval areas of hair loss with generally normal-looking skin
Alopecia totalis	Complete or nearly complete loss of scalp hair
Alopecia universalis	Extensive loss of scalp hair together with eyebrows, eyelashes and other body hair
Ophiasis-pattern alopecia areata	Band-like hair loss around the sides and back margins of the scalp
Central centrifugal cicatricial alopecia	Hair loss beginning around the crown or centre of the scalp and gradually spreading outwards; itching, burning, tenderness and hair breakage may occur

Alopecia Symptoms in Men

Alopecia can occur in many forms in men. But androgenetic alopecia commonly produces a recognisable male pattern. Typical symptoms of alopecia in men include:

Gradual recession of the hairline at the temples
Thinning over the crown or vertex
Progressive hair loss over the front and top of the scalp
Increasing visibility of the scalp
Gradually finer and shorter hairs in affected areas

The sides and back of the scalp are often relatively preserved in male pattern hair loss. Other forms, including alopecia areata, may instead cause round scalp patches or loss of beard hair.

Alopecia Symptoms in Women

Women can develop the same broad types of alopecia, but female pattern hair loss usually differs from the typical male pattern.

Common alopecia symptoms in women include:

Widening of the central hair parting
Gradual thinning over the top or crown of the scalp
Reduced overall hair density
Increasing visibility of the scalp through the hair
Relative preservation of the frontal hairline in many cases

Sudden diffuse shedding may occur after childbirth or another significant physiological stress and may be associated with telogen effluvium.

Alopecia Symptoms in Children

Hair loss in children can occur for several reasons. The appearance of the scalp provides important clues about its cause. Possible symptoms of alopecia in children include:

Smooth, round or oval bald patches
Scaly patches of hair loss
Broken hairs or black dots on the scalp
Scalp itching
Redness or inflammation
Hair loss around areas exposed to repeated pulling or tension
Eyebrow or eyelash loss
Nail pitting in some children with alopecia areata

Alopecia areata typically produces smooth bald patches with relatively normal-looking skin. Tinea capitis can instead cause scaling, itching, broken hairs or black dots and may occasionally produce a painful, inflamed swelling.

Can You Have Alopecia Without Symptoms?

Alopecia refers to hair loss or reduced hair growth, so some change in hair density or distribution is eventually present. However, it can develop without pain, itching, redness or other noticeable scalp symptoms.

Androgenetic alopecia may progress slowly enough that a person notices only a widening parting, receding hairline or reduced density. Alopecia areata can also cause a smooth bald patch without discomfort.

Early or gradual hair loss may go unnoticed until enough hair has been lost to make the scalp more visible or until someone else notices the change.

How are Alopecia Symptoms Diagnosed?

Alopecia is assessed by looking at the pattern and speed of hair loss, the condition of the scalp and other associated symptoms. A medical history can also help identify recent illness, medicines, nutritional changes, physical tension on the hair or a family pattern of hair loss.

Further investigations depend on the suspected type.

The table below explains the assessments used to diagnose alopecia and their purpose:

Diagnostic Test or Assessment	Purpose
Medical history	To assess when hair loss began, how quickly it progressed and possible illness, medicines, dietary changes, stressors or family history
Hair and scalp examination	To identify whether hair loss is patchy, patterned, diffuse or scarring and check for redness, scaling or loss of follicular openings
Hair-pull test	To assess whether increased active shedding is occurring
Trichoscopy or dermoscopy	To examine hair shafts, follicular openings and scalp changes more closely
Blood tests	To investigate nutritional, hormonal or other medical causes when suggested by the medical history or examination
Fungal testing	To identify tinea capitis when scaling, broken hairs or other features suggest a fungal scalp infection
Scalp biopsy	To examine follicular tissue when the diagnosis remains uncertain or scarring alopecia is suspected

FAQs

Q1. What is the first symptom of alopecia?

Ans: The first symptom of alopecia may appear as increased hair shedding, gradual thinning, a widening parting, receding hairline or a distinct bald patch, depending on the type.
Q2. Can alopecia cause complete hair loss?

Ans: Yes. Severe forms, such as alopecia totalis, can cause complete scalp hair loss, while alopecia universalis can also affect eyebrows, eyelashes, and body hair.
Q3. Can alopecia cause an itchy scalp?

Ans: Yes. Some forms of alopecia can cause itching, burning or tenderness. However, other forms may cause hair loss without any scalp discomfort.
Q4. Can alopecia affect eyebrows and eyelashes?

Ans: Yes. Alopecia areata can affect the eyebrows and eyelashes as well as scalp hair, particularly when hair loss becomes more extensive.
Q5. Can children develop alopecia?

Ans: Yes. Children can develop alopecia areata, traction-related hair loss, and other conditions that cause alopecia. Scalp infections can also produce patchy hair loss.
Q6. Can alopecia cause permanent hair loss?

Ans: Yes. Some forms of alopecia, especially scarring alopecia, can cause permanent hair loss by damaging the hair follicles. In many non-scarring types, however, the follicles remain intact, and hair may grow back.
Q7. Can alopecia symptoms come and go?

Ans: Yes. Alopecia areata can cause periods of hair loss followed by regrowth, with new patches sometimes appearing later.
Q8. When should I see a doctor for alopecia symptoms?

Ans: Seek medical assessment for alopecia symptoms if hair loss is sudden, rapidly worsening, unexplained or accompanied by scalp pain, redness, scaling, inflammation or other unusual symptoms.
