Tell the clinic before hair PRP if your scalp is sunburned, sore, blistered or peeling. An elective injection should not be planned from a photograph or a fixed internet waiting period without considering the skin and your symptoms. The immediate question is what the scalp needs now, then whether and when the proposed procedure is appropriate.
Thinning hair can leave more scalp exposed to the sun. Protecting that skin belongs in a considered hair-care plan, alongside understanding the cause of the hair loss itself.
Describe the skin, not only the travel dates
Explain when the sun exposure happened, which areas are affected and whether there is blistering, pain, swelling or broken skin. Mention products used, other skin conditions and any symptoms that extend beyond the scalp. A recent holiday is context, not a diagnosis.
If the scalp has not been examined, do not assume every red or tender area is sunburn. Other inflammatory or infectious conditions can look similar to a patient. A clinician can decide whether a hair-treatment appointment remains appropriate or a different assessment should come first.
Discuss the scalp changes with The London PRP Clinic before your appointment. A clear description helps the team arrange the right next step rather than discover the problem only when you arrive for treatment.
Let the skin recover under appropriate advice
The American Academy of Dermatology recommends getting out of the sun, cooling the skin and using gentle measures to relieve sunburn. It advises leaving blisters intact rather than popping them. Its guidance is about burn care, not a protocol proving when PRP can restart.
Seek medical advice if the burn is extensive, blistering is significant, pain is severe or you feel unwell. Worsening symptoms or concern about infection need assessment. Do not wait for an elective cosmetic appointment to address a problem that needs medical attention sooner.
There is no universal countdown in this guide
A date on the calendar does not show whether the scalp is ready for injections. The extent of the burn, current skin integrity, tenderness and the planned treatment all matter. Ask the treating clinician what needs to be checked before going ahead.
Do not use makeup, hair fibres or a soothing product to conceal the condition at the appointment. The clinician needs an accurate view of the treatment area. Explain what you have applied so that irritation or product effects are not mistaken for another condition.
PRP is not established sunburn treatment
PRP for a selected hair-loss diagnosis should not be sold as a way to repair ordinary sunburn or make it safe to inject inflamed skin. A biological explanation about growth factors is not evidence for every proposed use.
If treatment is deferred, ask what the next assessment should cover and how to review suitability. The decision should be tied to the actual skin and the hair-loss diagnosis, not a promise that a procedure will accelerate recovery from sun exposure.
Protect exposed areas as part of daily care
The Academy advises protecting areas of hair loss from the sun with a suitable covering or sunscreen. Its patient guidance recommends broad-spectrum, water-resistant SPF30 or higher for exposed skin, with reapplication as directed. The product must suit your skin and the condition being treated.
A wide-brimmed hat can protect the scalp without requiring a product on a sore area. Avoid a tight or abrasive covering that makes tenderness worse. Ask for individual advice if you have open skin, a new procedure or a condition requiring specific scalp products.
Separate burn recovery from hair-loss assessment
A visible scalp can be due to different hair-loss patterns. Once an acute skin problem is addressed, a useful consultation can consider the history, examination and whether the loss is temporary, patterned or inflammatory. Sun protection does not replace that diagnosis.
Equally, a PRP course does not replace routine skin protection or assessment of a persistent lesion. Tell a clinician about a patch that does not heal or a changing spot, rather than assume it is part of hair shedding or a previous burn.
Make a practical appointment plan
Ask The London PRP Clinic about assessment and the next suitable step. Confirm any change of appointment, complete fees and the actual rescheduling terms before travelling. Your plan should state what needs review and who confirms whether treatment can proceed.
The value of doctor-led care is a clear decision that considers the scalp in front of the clinician, the evidence for the proposed treatment and your priorities. An appropriate delay can be part of careful care, rather than a reason to rush into a different procedure.
