How should you photograph your hair to judge whether treatment is helping?
Use a repeatable set-up, not a single reassuring selfie. For a useful comparison, keep the light, camera position, distance, hair preparation and views as consistent as possible. Photographs can document visible coverage, but they cannot diagnose every cause of hair loss, measure every follicle or prove that one treatment caused a change.
For patients considering PRP, reliable baseline images make the later conversation more honest. Ask The London PRP Clinic by The Wellness about a hair-loss assessment and how progress will be recorded before agreeing to a course.
Why photographs need a method
A photograph is a record of what the camera sees under particular conditions. A darker room, a different parting or a closer crop can change the impression of scalp visibility. The practical aim is to remove avoidable differences so that the clinician is comparing your hair rather than your photography.
Clinical PRP research has used global photography alongside more focused measurements. For example, a randomised trial of 40 patients used global photographs, hair count and shaft calibre at baseline, three months and six months. That study illustrates why an image is one part of assessment, not the whole outcome. Hausauer and Jones, PRP regimen trial.
The checklist below is a practical recording method, not a validated diagnostic test or a claim that a phone camera can replace an examination.
Build a small, repeatable photo set
Choose fixed views. Ask your clinician which areas need recording. A set might include the front hairline, each temple, the central parting and the crown, with the same views repeated later. Do not add a flattering angle to the follow-up set while leaving out the original area of concern.
Keep the light the same. Choose one predictable light source and avoid switching between direct flash, a bright window and overhead bathroom lights. If the original photographs were taken in clinic, ask whether the follow-up can use the same set-up.
Keep position and distance consistent. Use a fixed camera position or simple reference points for where you sit and where the camera is held. Ask another person to help if that makes the crown view more consistent. Avoid changing lenses, portrait effects or wide-angle distance between sessions.
Record hair preparation. Compare dry with dry or wet with wet, and keep styling and the parting consistent. Record a haircut or major change in length. If fibres, concealer or another cosmetic product has been used, record it and ask the clinician how to prepare the next set.
Keep the originals. Save the date and unedited files. Do not use smoothing, filters, retouching or a crop that removes a thinning area. An attractive image is not the same as useful evidence.
These are controls for comparison. They do not create a medical diagnosis or a guaranteed sensitivity to small changes.
Decide the review schedule before taking dozens of images
Ask when photographs will be useful for your treatment plan and what the clinician will assess. Daily checking can create a folder of incomparable pictures rather than a clear record. Keep a short log of treatment dates and important changes to your regimen so the review has context.
Do not turn a published trial's time points into a promise about your own response. PRP studies use different regimens and outcomes. A systematic review found possible benefit in male pattern hair loss but low-quality evidence, moderate risk of bias and substantial differences between studies. A clinic should explain that uncertainty rather than treating any particular month as a guaranteed transformation. Donnelly and colleagues, systematic review.
If you want to understand review timing rather than photography conditions, our week-16 photo-review guide addresses that separate question.
What a photograph cannot settle
Images alone cannot reliably tell you why hair is being lost. AAD describes diagnosis as beginning with history and examination, with tests such as blood tests or scalp biopsy when the suspected cause requires them. A treatment plan should follow that assessment, not the other way around. American Academy of Dermatology.
If a photograph appears better after PRP and another treatment were started together, it cannot isolate the contribution of PRP. If your hair is longer or styled differently, a clinician may be unable to make a fair comparison. It is better to say “uncertain” and improve the next set than to label an ambiguous picture a success.
Ask whether a closer scalp examination or documented measurement would help answer the remaining question. Our guide to trichoscopy for hair loss explains a different way of looking at the scalp. Availability and suitability should be confirmed for your appointment.
Share images through the agreed route
Scalp photographs are personal health information in the context of your care. Ask the clinic how to send them securely and how they will be used. Consent to clinical photography should not be treated as automatic permission for advertising. If images may be used publicly, ask for the separate terms before agreeing.
Avoid posting identifiable photographs online to obtain a diagnosis from strangers. A camera angle cannot provide the history, examination and professional responsibility of a clinical assessment.
Use the record to make a decision
At review, put the original and current images side by side with dates visible. Ask the clinician to explain what looks different, what cannot be compared and whether the change is meaningful enough to alter the plan. Agree what happens if there is no convincing improvement.
Book an enquiry with The London PRP Clinic. Say whether you need a first diagnosis, a review of an existing course or help deciding whether further treatment is worth it. Ask for the scope, current fee and proposed recording method before you commit.
Can a selfie prove new hair growth?
No. It may show a visible change, but comparison conditions and clinical context matter. A single image cannot establish the cause of that change.
Should every photograph be taken under harsh light?
Consistency matters more than choosing a deliberately flattering or alarming light. Agree a repeatable set-up with the clinician and use it for both baseline and follow-up.
Is a changed hairstyle a problem?
It may make comparison harder. Keep a record of the change and tell the clinician rather than presenting the photographs as directly equivalent.
Do better photographs mean I do not need a diagnosis?
No. Photographs document appearance. A clinician still needs to assess the cause and whether the proposed treatment fits it.
