About this procedure
Trichoscopy is a noninvasive magnified examination of hair shafts, follicular openings and scalp skin. It can reveal differences in hair density, shaft appearance, scaling and inflammation that are difficult to assess with an ordinary visual examination.
Possible causes and features
The test contributes to a broader dermatology assessment rather than providing a stand-alone diagnosis. It may be considered for diffuse shedding, patches without hair, a widening part, hair breakage, itching, redness or dandruff.
Different conditions can produce similar complaints, including temporary telogen shedding, hereditary pattern hair loss, alopecia areata, dermatitis and fungal infection. Evaluating both hair and scalp is therefore important.
Clinical assessment and next steps
The clinician asks when the problem started, how it has developed and whether medicines, health conditions or hair care could play a role. The scalp is then examined under magnification. Further blood tests or other investigations are requested only when the clinical picture indicates a need.
Before the visit, mention any medicated scalp lotions, hair coloring or products used to conceal thinning. Confirm preparation instructions with the clinic. Trichoscopy findings must be interpreted alongside the history and examination, not from isolated images or as a guarantee of a diagnosis.

Signs and symptoms
- Noticeable hair shedding or thinning.
- Round or patchy bald areas and brittle or broken hairs.
- Itchy, red, flaky or otherwise changed scalp skin.
Diagnosis and tests
A magnified view helps assess hair shafts, follicular openings and scalp inflammation or vascular features. Results are combined with clinical examination and history, and additional tests are ordered only when indicated.
Care and treatment approaches
Trichoscopy itself is not a treatment. Findings may guide an individual plan for alopecia, dermatitis or infection. Do not interpret isolated pictures as a diagnosis or self-prescribe hormonal treatments.
When to seek urgent care
Rapidly worsening painful scalp inflammation, pus, swelling or fever needs prompt evaluation for possible infection. Call 103 in Ukraine for severe illness with breathing or consciousness impairment. Gradual uncomplicated hair loss is not an emergency.
Frequently asked questions
Is trichoscopy painful?
Usually not. It is an optical inspection with no cuts or needles.
Do I need blood tests before trichoscopy?
Not everyone does. The need for laboratory work depends on the symptoms and examination findings.
Can trichoscopy identify the cause of hair loss with 100% certainty?
No. It helps refine the diagnosis but must be interpreted together with the history and other clinical information.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
