An itchy or inflamed scalp should be assessed before elective PRP. Eczema, contact dermatitis, infection and other scalp conditions can look similar, and a hair-loss treatment is not a substitute for identifying why the skin is irritated.

Does every itchy scalp mean eczema?
No. Atopic dermatitis is one possible diagnosis, but seborrhoeic dermatitis, psoriasis, contact reactions and infection are among other possibilities. The symptoms, distribution, timing and examination help distinguish them.
Tell the clinician about new hair products, dye, topical treatments, washing routines and whether irritation affects other areas. Bring photographs from a flare if the skin has settled. A clear diagnosis can prevent repeated changes of product that make the problem harder to interpret.
Why does the skin barrier matter before PRP?
Eczema can involve inflamed, scratched or broken skin. DermNet describes infection among its complications. Passing needles through an affected area raises a different practical question from injecting an otherwise healthy scalp.
The procedural clinician should assess the treatment area and any concern about infection before proceeding. PRP should not be presented as a way to disinfect the scalp or bypass treatment of active skin disease. Your own blood is not a substitute for intact skin, sterile technique or appropriate clinical judgement.
Should active irritation be treated before a hair course?
The first step is understanding what is active and why. A clinician may recommend managing the scalp condition before reassessing suitability for an elective procedure. The timing depends on the diagnosis and recovery, not a universal number of days.
Do not stop prescribed eczema treatment to make the skin appear untreated for a consultation. Tell the clinician what you use and how often. Where different clinicians manage the skin and hair loss, a joined-up plan is more useful than conflicting instructions.
Ask our concierge what assessment is appropriate. Share the question you want answered and ask which records would help.
Can eczema and pattern hair loss coexist?
They can be separate problems requiring separate assessment. Itching, scratching, shedding, breakage and gradual thinning are not interchangeable descriptions. Improvement in one symptom does not prove that a hair-growth treatment is working.
Ask what diagnosis the proposed PRP course is intended to treat. Evidence for PRP in pattern hair loss should not be rewritten as evidence that it cures eczema or every form of scalp inflammation. A baseline should record both the hair concern and the condition of the skin.
When should I seek prompt medical advice?
Increasing pain, spreading redness, discharge, fever or feeling unwell needs prompt assessment. In a person with eczema, a sudden painful blistering eruption also needs urgent clinical advice rather than an aesthetic appointment.
The appropriate response depends on the symptoms and examination. This guide cannot distinguish infection from a flare or prescribe a treatment. Do not cover a concerning area with new cosmetic products while waiting for a PRP booking to solve it.
What should a useful consultation decide?
It should identify the likely scalp condition, whether anything needs treatment first, whether further assessment is needed and when PRP suitability could be reviewed. If PRP is not appropriate, the explanation should be clear.
For someone managing travel and work, a realistic timetable matters more than a guaranteed appointment date. Ask how aftercare fits with your existing skin routine and what symptoms should bring you back sooner. Avoid paying for a course before those questions are answered.
What does premium care mean in practice?
At the premium end of published London hair-PRP menus, Harley Street Skin Clinic lists £600 with a doctor, £750 with a senior doctor and £900 with a lead doctor per session. Those are that clinic's hair-treatment prices, not a quote for a facial, a guarantee of superior results or The London PRP Clinic's fees.
Ask for an individual written quote after the diagnosis and suitability discussion. It should explain the proposed procedure, who performs it, review arrangements, alternatives and what happens if treatment is deferred. A premium decision can be a reason not to proceed; a high price cannot make an unsuitable procedure appropriate.
Discuss your goals, suitability and a complete quote on WhatsApp. An enquiry starts a discussion; it does not confirm availability or commit you to treatment.
