Hair loss is a common concern, but not every type of hair loss has the same cause. Some people experience genetic hair loss, while others develop autoimmune hair loss that appears suddenly. Understanding alopecia areata vs pattern hair loss is important because each condition has different causes, symptoms, and treatment options.
At PURE Medical Spa Chicago, our physician-led PURE Hair ReGrow program begins with an accurate diagnosis. Before recommending treatment, our physician-led evaluation identifies the underlying cause so you receive care tailored to your condition.

What Is Alopecia Areata?
Many people ask, What is alopecia areata?
Alopecia areata is an autoimmune scalp condition in which the immune system mistakenly attacks healthy hair follicles. Because it is an autoimmune condition, it often causes sudden hair loss instead of gradual thinning.
Common symptoms include:
- Round bald patches.
- Smooth areas of hair loss on the scalp.
- Sudden patchy hair loss developing over days or weeks.
- Hair loss affecting the beard, eyebrows, or eyelashes.
- New bald patches appearing in different areas.
Unlike hereditary baldness, alopecia areata is not caused by DHT or inherited pattern hair loss.
What Is Pattern Hair Loss?
Another common question is, What is pattern hair loss?
Pattern hair loss, also called androgenetic alopecia, is the most common form of genetic hair loss. It develops gradually because genetically sensitive hair follicles become smaller over time.
The pattern of hair loss is predictable.
- Men usually experience recession around the temples and crown.
- Women often develop diffuse thinning across the top of the scalp while preserving the frontal hairline.
These different patterns explain why physicians use separate staging systems for men and women.
Androgenetic Alopecia vs Alopecia Areata
Understanding androgenetic alopecia vs alopecia areata helps explain why one treatment does not work for every patient.
Alopecia areata is an autoimmune disorder that usually causes sudden, circular patches of hair loss.
Pattern hair loss develops gradually because of genetics and hormone sensitivity.
Although both conditions can lead to thinning, their progression, diagnosis, and treatment approach are very different.
What Is the Difference Between Alopecia Areata and Pattern Baldness?
Many patients ask, What is the difference between alopecia areata and pattern baldness?
The biggest difference is the underlying cause.
- Alopecia areata is an autoimmune disease.
- Pattern hair loss is hereditary and hormone-related.
Alopecia areata usually causes round bald patches, while pattern hair loss causes gradual thinning across predictable areas of the scalp.
Unlike alopecia areata, pattern hair loss follows recognizable stages over time.
Does Alopecia Areata Cause Round Bald Patches?
Yes. One of the hallmark symptoms of alopecia areata is the sudden appearance of smooth, circular bald patches.
However, similar symptoms can occasionally occur with other conditions, so a professional evaluation is important before beginning treatment.
Common Causes of Patchy Hair Loss
Patchy hair loss may result from several conditions, including:
- Alopecia areata.
- Scalp infections.
- Scarring alopecias.
- Certain inflammatory scalp conditions.
- Other forms of hair loss.
Because there are many different causes, self-diagnosis can be misleading.
Why Hair Loss Diagnosis Matters
An accurate diagnosis should always come before treatment.
Your provider may review:
- Medical history.
- Hair growth pattern.
- Scalp examination.
- Family history.
- Hair growth cycle.
Depending on your symptoms, blood tests or additional evaluation may be recommended to identify medical conditions contributing to hair loss.
At PURE Medical Spa Chicago, every consultation focuses on identifying the cause before recommending treatment.
Can Alopecia Areata Be Reversed or Is It Permanent?
Many people ask, Can alopecia areata be reversed or is it permanent?
The answer varies.
Some people experience spontaneous regrowth because the follicles remain alive. Others experience recurring episodes over time.
Pattern hair loss generally progresses gradually without treatment because it is hereditary rather than autoimmune.
Is Alopecia Areata Autoimmune or Genetic?
Alopecia areata is primarily an autoimmune disease.
Pattern hair loss is primarily hereditary.
Although both conditions affect the scalp, they require different treatment approaches.
How Do Doctors Diagnose Alopecia Areata vs Pattern Hair Loss?
Doctors evaluate several factors, including:
- Hair loss pattern.
- Speed of progression.
- Signs of hair loss.
- Medical history.
- Family history.
- Scalp examination.
- Hair density.
- Current stage of hair loss.
Additional laboratory testing may be recommended when appropriate.
This comprehensive approach helps distinguish autoimmune hair loss from hereditary thinning before treatment begins.
Why Diagnosis Comes First
The most effective treatment depends on an accurate diagnosis.
Some regenerative therapies may be appropriate for pattern hair loss but not for active autoimmune disease. Likewise, treatments designed for hereditary thinning may not address inflammation associated with autoimmune conditions.
Although some patients eventually consider hair transplantation, surgery is generally not the first option for active alopecia areata.
