When you track hair loss before a dermatologist visit, you turn a vague worry into clear information. Appointments are short, and hair changes slowly. A few photos and notes prepared in advance help the doctor to see what has changed, find the cause and choose the right tests.
Why records help
- Hair loss often begins months after its trigger, so memory alone is unreliable.
- A doctor sees your hair on one day only. Photos show the trend.
- Notes on shedding, health and hair care point towards a diagnosis.
- Records let you judge later whether a treatment is working.
Step 1: Take consistent photos
Photos are the most useful record. Take a set once a month.
- Use the same room, lighting and time of day. Daylight from a window or a bright bathroom light works well.
- Have dry, clean hair without styling products, fibers or powders.
- Take the same views each time, listed below.
- Hold the camera at the same distance. Ask someone to help, or use a timer.
- Store them in a dated album.
The views to repeat every month:
- Top of the head with a center part.
- Front hairline with hair pulled back.
- Both temples.
- The crown, from above and behind.
- Any patch, with a ruler or coin beside it for scale.
Step 2: Record shedding
You do not need to count every hair. Choose one simple method and repeat it.
| Method | How to do it |
|---|---|
| Wash-day collection | Collect the hairs from the drain and comb after washing, and note whether the amount is small, medium or large |
| Sixty-second comb | Before washing, comb forward over a pale towel for one minute and count the hairs |
| Ponytail measure | Measure the circumference of your ponytail once a month |
Always note how many days it has been since you last washed, because the amount shed depends on it. Look at a few hairs: full-length hairs with a white bulb are shed hairs, and short pieces are broken hairs. See Hair Shedding vs Breakage: Key Differences.
Step 3: Build a timeline
Write down when you first noticed the change, then list anything from the previous six months:
- Illness, fever, surgery or injury.
- Pregnancy, childbirth or stopping breastfeeding.
- Starting, stopping or changing medicines, including contraception and supplements.
- Weight loss or a change of diet.
- Major stress or bereavement.
- New hair treatments: color, bleach, relaxers, keratin treatments, extensions.
Stress and Hair Loss: Understanding Telogen Effluvium explains why the timing matters.
Step 4: Note your health and family history
- Current medicines and supplements, with doses.
- Medical conditions, including thyroid problems, anemia and skin conditions.
- For women: details of your periods and any changes.
- Other symptoms: tiredness, feeling cold, weight change, new facial or body hair, acne.
- Relatives with hair loss, on either side of the family, and the age it began.
Step 5: Describe your hair care
- How often you wash, and with what.
- Heat styling and how often.
- Chemical treatments and their dates.
- Usual hairstyles, especially tight ones.
- Scalp symptoms: itching, burning, tenderness, flaking. See Persistent Scalp Flaking: When to See a Dermatologist.
Step 6: Prepare your questions
- What type of hair loss do I have?
- What is the likely cause?
- Do I need blood tests or other tests?
- What are my treatment options, and how long before I see results?
- Is this likely to be temporary or long-term?
- What should I change in my hair care?
- When should I come back?
On the day
- Come with clean, dry hair and no hair fibers, sprays or tight styles, so that the scalp can be examined. If your hair is in braids or a weave, ask the clinic in advance whether it should be taken down.
- Bring your notes, photos and a list of products, or the products themselves.
- Do not be embarrassed to say how the hair loss makes you feel.
After the visit
Keep taking monthly photos in the same way. Most treatments need three to six months before a fair comparison can be made. The Hair Length Tracker can hold your monthly measurements, and Hair Thinning: Causes and When to Get Help gives an overview of causes and treatments.

Frequently asked questions
How often should I take hair loss photos?
Once a month is enough. Hair changes slowly, and more frequent photos mostly show differences in lighting and styling.
Should I wash my hair before a dermatology appointment?
Clean, dry hair without styling products is usually best for hair loss. If your problem is flaking, some doctors prefer you not to wash that day. Ask the clinic if you are unsure.
Is counting shed hairs accurate?
It is a rough measure, but repeating the same method on the same schedule shows whether shedding is rising, falling or steady.
