Hair loss appointments are short and easy to waste. People arrive without a timeline, get asked when it started, say something like a while ago, and leave with a general answer to a question they never managed to make specific. Ten minutes of preparation changes what you get out of it considerably.
What to bring
The American Academy of Dermatology describes what a dermatologist does at this visit: asks questions about the timing and onset of hair loss, looks closely at the scalp, nails and any other area with hair loss, tests the health of the hair by gently pulling on it, and may order a blood test or scalp biopsy to rule out underlying disease, vitamin deficiency, hormone imbalance or infection. Your job is to make the history half of that accurate.
Worth assembling beforehand:
- A timeline. When you first noticed it, whether it was sudden or gradual, whether it has been steady or come in episodes.
- Photos over time. Phone photos of your part, hairline and crown from a few months or years back are genuinely useful and hard to reconstruct from memory.
- A complete medication and supplement list, including doses, anything started or stopped in the past year, and over-the-counter products.
- Recent health events. Illness, surgery, pregnancy, significant weight change, high stress periods, new diagnoses. Shedding can lag the trigger by months.
- Family history on both sides, including who lost hair and roughly when.
- Your hair practices. Heat, chemical relaxing, coloring, tight styles, extensions, clips, adhesives, wig wear. Be straightforward about all of it.
- Symptoms besides shedding. Itching, burning, tenderness, redness, scaling, pain. These matter a great deal for narrowing the diagnosis.
Questions worth asking
Aim for questions whose answers change what you do next.
- What do you think this is, and how confident are you?
- Is this a scarring or a non-scarring type? This one question carries a lot, because it determines whether preserving remaining hair is urgent. A CMAJ review of primary cicatricial alopecia notes that any follicle destroyed by a primary cicatricial alopecia will never regrow hair.
- Is regrowth possible in my case, and on what kind of timeframe?
- What tests would help narrow this down, and what would each one rule in or out?
- Could any of my medications or conditions be contributing?
- Is this likely to progress, and what would progression look like?
- What are the options, including doing nothing, and what are the tradeoffs and risks of each?
- Is there anything I am doing to my hair that is making it worse?
- When should I come back, and what would be a reason to come back sooner?
If you are unsure about a proposed direction, a second opinion is a normal thing to seek and does not require justification.
Ask about documentation while you are there
This is the item people forget and then have to chase later. If you might pursue insurance coverage, a health savings account or a flexible spending account for a hair prosthesis, ask at this visit whether the clinician will provide a written letter describing the diagnosis and the medical necessity of a cranial prosthesis. The wording matters, because payers and benefit administrators generally recognize that term rather than wig. IRS Publication 502 similarly frames the medical expense provision around a wig purchased upon the advice of a physician for a patient who has lost all of their hair from disease.
Whether any of that applies to your circumstances is a question for your own plan and for a licensed tax professional. Getting the letter costs you one sentence in an appointment you are already having.
When to seek a dermatologist specifically
A primary care clinician can start the workup and is a reasonable first stop. A board-certified dermatologist is worth seeking out when the loss is patchy, spreading quickly, accompanied by scalp symptoms, or when the hairline is visibly receding, since scarring conditions in particular reward early evaluation. The AAD notes that effective treatment for hair loss begins with finding the cause.
What this article cannot do is tell you what you have. That requires someone looking at your scalp. Book the appointment and bring the list.
