What Is a Hair Loss Evaluation?
A hair loss evaluation is a dermatology visit dedicated to determining the cause, pattern, and stage of your hair loss. Because thinning hair can stem from genetics, hormones, stress, medical conditions, medications, or scalp disorders, an accurate diagnosis is the foundation for effective treatment.
Your dermatologist will review your health history, examine your scalp, and, when needed, use additional testing to rule in or rule out specific causes before recommending a treatment approach.
Who Should Consider a Hair Loss Evaluation?
An evaluation is a good next step if you're noticing:
Gradual thinning on the top of the head or crown
A widening part or more visible scalp
Increased hair shedding when washing or brushing
Patchy or sudden hair loss
Scalp itching, redness, flaking, or tenderness
Hair loss that started after an illness, stress, or a medication change
Early evaluation matters because many treatment options, including PRP therapy, work best when hair follicles are still active.
What Happens During Your Evaluation
Your visit is thorough but straightforward, and most evaluations can be completed in a single office appointment.
Step 1: Medical History Review
Your dermatologist will ask about when your hair loss started, your family history, medications, diet, stress levels, and any recent illnesses.
Step 2: Scalp & Hair Examination
A close visual and manual exam of your scalp and hair helps identify patterns of thinning, inflammation, or scarring.
Step 3: Diagnostic Testing (If Needed)
Depending on your exam, your dermatologist may recommend a pull test, dermoscopy of the scalp, or bloodwork to check for thyroid, iron, or hormone-related causes.
Step 4: Personalized Treatment Plan
Once a cause is identified, your dermatologist will discuss treatment options suited to your diagnosis, goals, and stage of hair loss.
Common Causes of Hair Loss We Evaluate For
Hair loss is rarely one-size-fits-all. Some of the most common causes we look for include:
- Androgenetic alopecia (male and female pattern hair loss)
- Telogen effluvium (shedding triggered by stress, illness, or hormonal changes)
- Alopecia areata (patchy autoimmune hair loss)
- Scarring (cicatricial) alopecias
- Thyroid disorders and nutritional deficiencies
- Medication-related or postpartum hair loss
Identifying which of these applies to you is what allows your dermatologist to recommend a treatment that actually addresses the cause, not just the symptoms.
Treatment Options After Your Evaluation
Once your evaluation is complete, your dermatologist may recommend one or a combination of the following:
- Topical or oral medications
- PRP (Platelet-Rich Plasma) therapy for patients with active follicles
- Nutritional or lifestyle guidance
- Treatment of underlying medical conditions contributing to hair loss
- Referral for advanced restoration options, if appropriate
For patients with early-stage thinning and follicles that are still active, PRP therapy is often one of the treatment options discussed as part of the plan.

- Identifies the true cause of your hair loss
