Hair and Scalp Disorders

  /    /  Hair and Scalp Disorders

Restore Scalp Health and Maintain Healthy Hair With Specialized Dermatologic Treatments.

Changes in hair growth, hair density, or scalp comfort can raise questions that are difficult to answer without medical evaluation. Because hair grows from follicles embedded within the skin of the scalp, concerns affecting the hair and scalp are closely connected. At Connolly Dermatology, we evaluate both the scalp skin and the hair follicles to determine the cause of hair and scalp disorder symptoms. This diagnostic approach bases treatment recommendations on the underlying condition rather than on appearance alone.

Hair and scalp disorders may involve inflammation, infection, genetic sensitivity, hormonal influences, or disruptions in the hair growth cycle. Some conditions develop gradually over time, while others begin more abruptly. Because multiple disorders can present with similar signs, such as shedding, thinning, itching, or scaling, accurate diagnosis plays a central role in determining next steps.

Our board-certified dermatologists offer comprehensive medical evaluations and treatments for a range of hair and scalp concerns. Care is guided by clinical examination, medical history, and diagnostic testing when indicated. Our goal is to help patients understand what is affecting their scalp and hair, and to recommend treatment strategies based on dermatologic standards of care.

Understanding Hair and Scalp Disorders

The scalp is skin with a dense distribution of hair follicles and sebaceous (oil) glands. Like skin elsewhere on the body, the scalp can develop inflammatory, infectious, and immune-mediated conditions. Because hair follicles continuously move through specific stages of growth and rest, changes affecting the scalp skin or follicles can directly influence hair density, shedding patterns, and scalp comfort.

Hair growth depends on follicles moving through the anagen (growth), catagen (transition), and telogen (resting) phases in a predictable cycle. When inflammation narrows the follicle opening, scale or buildup obstructs the follicle, or systemic factors disrupt the timing of the growth cycle, individuals may notice increased shedding, thinning, or changes in hair texture. Scalp symptoms such as burning, tenderness, or itching occur when the skin barrier is compromised or when follicles become inflamed.

Hair and scalp disorders may involve:

  • Alterations in the hair growth cycle due to systemic stressors, illness, or medications
  • Inflammation of the scalp skin related to dermatitis or immune activity
  • Infection or irritation of hair follicles caused by bacteria, yeast, or friction
  • Genetic or hormonal sensitivity that affects follicle size and longevity

These conditions can affect daily comfort and self-perception, particularly when hair loss or visible scalp changes alter appearance. Early evaluation helps clinicians determine whether medical conditions, inherited factors, or lifestyle-related contributors such as hair care practices or exposures are driving symptoms. Identifying the specific cause allows treatment plans to be tailored to the individual process involved, supporting more effective management than symptom-based care alone.

Common Hair and Scalp Disorders We Diagnose and Treat

Connolly Dermatology evaluates and manages common causes of hair loss and scalp symptoms using a structured, medical method. We connect your symptoms, scalp findings, and medical history to a specific diagnosis, so treatment addresses the underlying cause. Below are several hair and scalp disorders frequently addressed in clinical dermatology.

Alopecia

Alopecia is the medical term for hair loss. It is a broad category that includes several distinct conditions with different causes and patterns. Alopecia may be non-scarring or scarring, localized or diffuse, and temporary or persistent, depending on the underlying diagnosis.

Clinical features may include:

  • Patchy areas of hair loss
  • Diffuse thinning across the scalp
  • Sudden or gradual changes in hair density
  • Smooth areas of scalp without visible hair

Different types of alopecia are associated with various mechanisms. Some forms involve autoimmune inflammation targeting hair follicles, while others relate to genetic and hormonal sensitivity or disruptions in the hair growth cycle. Because alopecia encompasses multiple diagnoses, evaluation helps clarify the specific type and guide treatment decisions.

Androgenetic Alopecia

Androgenetic alopecia is a common cause of gradual, progressive hair thinning. It is associated with inherited traits and sensitivity of hair follicles to androgens. This sensitivity can shorten the hair growth phase and gradually reduce follicle size over time.

In men, androgenetic alopecia often presents with:

  • Recession at the temples
  • Thinning at the crown

In women, it more commonly appears as:

  • Diffuse thinning over the top of the scalp
  • A widening part without complete baldness

Androgenetic alopecia develops gradually and follows a recognizable pattern. Evaluation helps define the extent of thinning and determine whether treatment may help preserve existing hair.

Telogen Effluvium

Telogen effluvium occurs when an increased proportion of hair follicles enter the resting (telogen) phase of the hair growth cycle. This shift can result in noticeable shedding, often observed during washing or brushing.

Factors that may be temporally associated with telogen effluvium include:

  • Recent illness or surgery
  • Significant physiological stress
  • Hormonal changes, such as postpartum shifts
  • Nutritional deficiencies
  • Medication changes

Telogen effluvium is frequently self-limited once the triggering factor resolves, although shedding can persist in some individuals. Evaluation focuses on identifying potential contributors and assessing whether additional testing or monitoring is appropriate.

Scalp Dermatitis

Scalp dermatitis is a general term for inflammatory conditions involving the scalp. It may include seborrheic dermatitis, irritant, or allergic contact dermatitis, or inflammation related to atopic dermatitis (eczema).

Symptoms may include:

  • Redness or irritation of the scalp
  • Persistent itching or sensitivity
  • Scaling or flaking
  • A burning or tight sensation

Depending on the type, scalp dermatitis may be associated with product sensitivity, underlying skin conditions, or inflammatory responses to naturally occurring microorganisms on the skin. Because symptoms can overlap with other scalp disorders, diagnosis helps guide appropriate treatment.

Dandruff

Dandruff refers to visible flaking of the scalp and may occur with minimal inflammation or as part of seborrheic dermatitis. Some individuals encounter mild, intermittent flaking, while others have persistent or recurrent symptoms.

Common features include:

  • White or yellowish flakes
  • Mild itching
  • Seasonal variation in symptoms

Although dandruff is usually not medically dangerous, persistent or severe flaking can reflect an underlying inflammatory scalp condition that may benefit from targeted treatment.

Folliculitis

Folliculitis is inflammation of hair follicles that can be infectious or noninfectious. On the scalp, it may present as small red bumps, pustules, or areas of tenderness.

Symptoms may include:

  • Red or pus-filled bumps around follicles
  • Soreness or discomfort
  • Itching or burning
  • Crusting in affected areas

Treatment depends on the cause and extent of follicular inflammation. Evaluation helps determine whether bacterial, yeast-related, or irritant factors are contributing and guides the selection of therapy.

Signs and Symptoms That May Warrant Evaluation

Hair and scalp conditions may begin with subtle changes that gradually progress. Monitoring symptoms helps determine when a professional evaluation may be helpful.

Signs that prompt evaluation include:

  • Increased hair shedding
  • Gradual or sudden thinning
  • Patchy hair loss
  • Persistent itching or flaking
  • Redness or scaling of the scalp
  • Painful or inflamed follicles
  • Changes in hair texture or density

When symptoms persist, worsen, or occur alongside scalp discomfort, evaluation helps clarify the cause and inform care decisions.

Diagnosis and Evaluation

Because multiple conditions can cause similar hair and scalp symptoms, the diagnosis focuses on identifying the underlying process. At Connolly Dermatology, evaluation begins with a detailed clinical assessment. We combine scalp findings with your timeline of symptoms, medical history, and targeted testing so treatment aligns with the confirmed diagnosis.

Clinical Examination

We examine the scalp and hair to assess distribution, density, inflammation, scaling, and follicular patterns. We look for whether thinning is diffuse or patterned, shedding is active, and the scalp skin shows signs of redness, scaling, or pustules. 

When indicated, we utilize magnification techniques, such as dermoscopy or trichoscopy, during the examination. These tools allow closer assessment of follicle openings, hair shaft thickness, and signs of inflammation that are not visible without magnification.

Medical History Review

Understanding when symptoms began, how they have changed, and whether there are associated medical conditions, medications, or recent life events provides important diagnostic context. 

We ask about the timing of shedding, recent illnesses, surgery, childbirth, weight changes, and new prescriptions or supplements. We also review hair care practices, including chemical treatments, tight hairstyles, and new shampoos or styling products that may irritate the scalp.

Diagnostic Testing

In some cases, additional testing may be recommended, such as:

  • Blood tests or hormonal evaluations to assess potential contributing factors
  • Scalp biopsy when the diagnosis is unclear or complex
  • Laboratory testing to evaluate for infection or inflammatory conditions

Testing is selected based on specific findings, such as diffuse shedding with suspected nutritional deficiency or pustules suggesting folliculitis. This stepwise method ensures that clinicians base treatment recommendations on the identified cause rather than on appearance alone.

Pattern Tracking and Treatment Response Monitoring

When a condition requires follow-up, we may document baseline findings to assess changes over time. This can include standardized photographs of the hairline or part, notes describing the distribution of scale or redness, and measurements of affected areas when hair loss is patchy. 

Tracking allows clinicians to assess whether shedding is improving, whether inflammation has decreased, and whether adjustments to treatment are necessary.

Hair and Scalp Disorder Treatments

Treatment depends on the specific hair or scalp disorder, the severity of the symptoms, and individual medical considerations. Some conditions require short-term treatment, while others benefit from ongoing management and care.

Topical Treatments

Topical therapies may include medicated shampoos, solutions, foams, or creams selected for the diagnosis. 

  • For dandruff or seborrheic dermatitis, treatment may focus on using antifungal or keratolytic shampoos on a regular schedule. 
  • For inflammatory scalp dermatitis, we may recommend topical anti-inflammatory medications applied to affected areas for a specific duration. 
  • For folliculitis, clinicians use antibacterial washes or topical antibiotics when lesions are localized.

Oral Medications

When topical therapy does not provide adequate control or when disease involvement is more extensive, clinicians consider oral medications as an alternative. The choice depends on the diagnosis and clinical findings. 

  • For bacterial folliculitis affecting multiple areas, an oral antibiotic may be appropriate for a defined course.
  • For inflammatory hair loss patterns, clinicians discuss systemic therapy when the diagnosis and medical history support its use. 

We review medication interactions, pregnancy considerations, and monitoring needs before recommending oral treatment.

Procedural and Referral-Based Options

For specific hair loss conditions, clinicians discuss procedural therapies or hair restoration techniques. The appropriate option depends on the diagnosis, degree of follicle activity, and the patient’s goals. 

If our office does not offer a treatment, we provide guidance and refer patients to appropriate specialists. We explain what the procedure entails, the conditions it addresses, and the type of evaluation typically required beforehand.

Supportive Hair and Scalp Care

Recommendations may also include adjustments to hair care routines, product selection, and scalp hygiene. We may advise a fragrance-free cleanser when contact dermatitis is suspected, a specific wash frequency when scale is significant, or avoidance of heavy oils if folliculitis is recurring. 

For patients with shedding, we may review brushing habits and heat styling frequency to reduce breakage that can be mistaken for hair loss. Clinicians tailor guidance to the diagnosis and the patient’s daily routines.

Prevention and Ongoing Management

Genetic factors or chronic inflammatory processes can influence certain hair and scalp conditions, which limit the ability to prevent them entirely. In these cases, management focuses on controlling symptoms, reducing recurrence, and maintaining scalp comfort through consistent, diagnosis-specific care. 

When clinicians identify thinning hair or recurring scalp symptoms early, they can begin treatment promptly. At the same time, follicles are still active, and inflammation is limited, which can broaden management options and help prevent avoidable progression.

Core Long-Term Management Principles

Long-term management plans are based on the confirmed diagnosis and may include:

  • Ongoing Treatment for Chronic Conditions: Continuing prescribed therapies on a defined schedule, even after visible symptoms get better. 
  • Avoidance of Identified Triggers: Eliminating confirmed irritants or allergens, such as specific hair products or ingredients, when contact dermatitis or irritation is diagnosed. 
  • Periodic Follow-up: Reassessment of scalp findings and hair patterns to monitor stability or progression. 
  • Treatment Adjustments: Modifying product type, frequency, or medication based on response or recurrence of symptoms.

Plans are reviewed and adjusted over time based on clinical findings. Maintaining scalp health may involve cleansing at a frequency suitable for the hair type, avoiding excessive heat and traction, and selecting products tailored to the scalp’s condition. These practices help support the scalp skin and reduce irritation that can contribute to shedding or inflammation. 

Condition-Specific Prevention and Maintenance

Scalp Dermatitis and Dandruff
Management may include a maintenance schedule with medicated shampoo, defined by the frequency of use after symptoms improve. When contact dermatitis is suspected, prevention requires consistent avoidance of the identified trigger, such as a specific fragrance, preservative, or category of styling products.

Folliculitis
Prevention focuses on reducing follicle irritation by washing after heavy sweating, avoiding tight headwear that increases friction and heat, and selecting non-comedogenic scalp products. When clinicians identify yeast involvement, they recommend periodic antifungal cleansing on a defined schedule.

Telogen Effluvium and Androgenetic Alopecia

For telogen effluvium, management focuses on addressing contributing factors such as iron deficiency, thyroid imbalance, or medication timing. For androgenetic alopecia, long-term care centers on preserving existing hair density and monitoring stability over time. For individuals at higher risk, periodic scalp evaluation can help identify early changes and guide timely adjustments to care.

Schedule a Hair and Scalp Evaluation — Clear Answers Begin With Proper Diagnosis

Hair loss and persistent scalp symptoms can be challenging to interpret without professional evaluation. Understanding the cause helps set realistic expectations and informs appropriate treatment options.

At Connolly Dermatology, we carefully assess hair and scalp disorders and recommend personalized care based on our clinical findings. If you are experiencing changes in hair growth, increased shedding, or ongoing scalp discomfort, our dermatologists can help you understand your condition and discuss next steps.
