PRP for Hair Loss | What the Week-16 Photo Review Shows and What Happens Next
Written and reviewed by the clinical team at The Wellness
Direct answer
A week-16 photo review compares your current hair appearance with your starting photographs. It is a decision point, not a promise that every patient will improve or that treatment is complete. Ask what has changed, how confidently the comparison can be made, and what the findings mean for your next step.
Understand the clinic’s reported measure
The London PRP Clinic reports its own outcome measure as follows: 87% of hair restoration patients show visible improvement at their week-16 photo review. This is the clinic’s reported photo-review measure, not a published clinical-trial result or an independently audited figure. It is not a guarantee for an individual patient, a percentage increase in hair density or proof that PRP alone caused every change.
Make the photographs comparable
Bring your starting photographs and ask how the review controls lighting, camera angle, hair position and styling. A change in the parting or light can change the impression of scalp coverage. Ask the clinician to describe the visible finding rather than relying on a general “looks better”. If other measurements were recorded at baseline, ask how they compare and what their limits are.
Check the diagnosis as well as the pictures
Female or male pattern hair loss, shedding and other scalp disorders are not interchangeable. The treatment plan should be based on a clinical assessment. The British Association of Dermatologists notes that research on PRP for female pattern hair loss is limited. Published reviews report encouraging findings but differences in treatment protocols and study quality leave uncertainty. A clinic photo review does not remove those limitations.
If there is visible improvement
Ask whether the change meets the goal you agreed at the start and whether improvement is accompanied by tolerable side effects. Discuss what happens if you continue, pause or use another treatment. Make sure the recommendation relates to your diagnosis and progress. Improvement at one review does not establish a fixed maintenance schedule or a reason to buy another course without discussion.
If change is smaller than expected
Ask the doctor to review the original diagnosis, treatment schedule and other possible contributors to hair loss. Relevant blood results, prescribed treatments and any supplements should be reviewed in context. Do not start iron, hormones or other supplements simply because hair photographs have not improved. Testing and supplementation should have a clinical reason. A revised plan may involve a different treatment or specialist advice, not more PRP.
Discuss costs before continuing
Current hair PRP prices are £450 per session or £1,215 for three sessions. Ask which further appointments are proposed, what is included and the total cost. Do not assume every patient needs the same number of sessions. The review should explain why a further procedure is expected to help and when the plan will be reassessed.
Leave with a written next step
Record what the review shows, what remains uncertain, the agreed plan and the next review point. Ask whom to contact about persistent pain, redness or other concerns after treatment. PRP uses your own blood but is not risk-free. A good review makes the next decision clearer; it does not turn an uncertain response into a promise.
Frequently asked questions
Does visible improvement mean a measured rise in hair density?
Not necessarily. A photographic appearance assessment and a quantified density measurement are different outcomes.
Does an unchanged week-16 photograph mean I need more PRP?
Not automatically. The diagnosis, treatment response and other contributors should be reviewed before agreeing to further procedures.
Can the clinic’s photo-review figure predict my own result?
No. A clinic-reported group measure is not an individual guarantee and is not a clinical-trial result.
