Itchy Scalp and Hair Loss: What to Check Before Booking PRP

An itchy scalp with hair loss needs a diagnosis, not an automatic course of injections. Dandruff, a reaction to a hair product, inflammation around the follicles and a fungal infection can look similar at first. Some causes need prescription treatment; a smaller group can damage follicles permanently. The useful first step is to identify what is happening on the scalp and whether the hair loss is a separate problem. [1-4]

You may be noticing flakes on a dark jacket, scratching during meetings or seeing more hair when you wash it. The urge is to buy a stronger shampoo or book the treatment that promises the fastest regrowth. A better starting point is a clear answer to two questions: what is causing the itch, and what is causing the change in hair density?

What the pattern can tell you

These clues help a clinician decide what to examine. They do not establish a diagnosis on their own.

• Loose flakes and an itchy scalp. Possible cause: Dandruff or seborrhoeic dermatitis. Next step: Ask a pharmacist about an appropriate shampoo; seek review if persistent or severe [1]

• Burning or irritation after a dye, spray or new product. Possible cause: Contact dermatitis. Next step: Tell the clinician exactly what you used and when [1]

• Small itchy spots that become sore or crusted. Possible cause: Scalp folliculitis. Next step: Have the affected area examined rather than treating every spot as dandruff [2]

• Scaling with patchy hair loss. Possible cause: Scalp ringworm, among other causes. Next step: Arrange a GP assessment; scalp ringworm usually needs prescription treatment [3]

• Pus spots, crusting, pain or shiny areas where hair has disappeared. Possible cause: An inflammatory or scarring scalp disorder. Next step: Seek prompt medical assessment [4]

The same person can have more than one problem. Pattern hair loss and a scalp condition should not be collapsed into a single explanation just because they appeared together. [5]

What you can do while arranging advice

For straightforward dandruff, a pharmacist can help you choose and use an anti-dandruff shampoo. NHS guidance suggests allowing up to four weeks to assess a suitable product, but advises a GP review sooner if the scalp is very itchy, red or swollen. Do not keep changing products indefinitely when the picture is different from simple flakes. [1]

Avoid picking at crusts or scratching spots. The British Association of Dermatologists advises this because it can worsen inflammation in folliculitis decalvans. Do not borrow someone else's steroid lotion or antibiotics: conditions that look similar may need different treatment. A clinician may need a swab, scraping, hair sample or, occasionally, biopsy to clarify the cause. [4]

If you would like help deciding the right appointment, request an assessment at The London PRP Clinic . Tell the team about itch, pain, scaling or discharge before discussing a treatment course.

When the scalp should be examined promptly

Do not treat new bald patches with crusting, pus, worsening pain or shiny scar-like skin as a cosmetic problem alone. BAD describes these features in folliculitis decalvans, a rare inflammatory condition in which damaged follicles cannot regrow. Early diagnosis and treatment may help limit further scarring. This does not mean every itchy scalp is a scarring disorder; it explains why the examination matters. [4]

Scalp ringworm also deserves a GP assessment rather than shampoo alone. It is a fungal infection, not a worm, and can cause patchy loss. [3]

Does PRP treat an itchy scalp?

The evidence discussed for hair PRP concerns androgenetic, or pattern, hair loss. It is not evidence that injections treat an undiagnosed itchy scalp. A 2024 systematic review of randomised trials found a possible improvement in hair density compared with placebo, but rated the evidence as low quality, with large differences between studies and publication bias. Those findings should not be transferred to infection or scarring scalp disease. [6]

That leaves a useful place for an honest consultation. If the scalp problem is treated and pattern thinning is also present, a doctor can discuss whether PRP belongs in the wider plan. If another treatment or specialist review should come first, that is the more valuable next step.

What does hair PRP cost in London?

At The London PRP Clinic, hair PRP is £450 per session or £1,215 for three sessions . Suitability and the full plan are agreed before treatment. Do not buy a course to find out what is causing your symptoms. [7]

Read the hair-treatment and assessment options and the clinic's evidence guide . Ask what outcome would be measured, when it would be reviewed and what would change the plan.

Bring this to your appointment

• When the itch started and whether thinning began before or afterwards.

• Photographs of the affected area in consistent light.

• Names or photographs of shampoos, dyes and scalp products.

• Details of pain, crusts, spots, discharge or spreading patches.

• Your medicines and any treatments already tried.

Common questions

Does itching mean my hair is growing back?

Itching is not a reliable measure of regrowth. Dandruff, irritation and folliculitis can all itch. Assess the scalp symptoms separately from any change in hair density. [1,2]

Can I book PRP if my scalp has spots?

Tell the clinic before booking. An assessment should establish the cause and whether treatment should wait. An injection appointment is not a substitute for investigating an inflamed scalp. [4,6]

Can a shampoo fix patchy hair loss?

Not every cause. Scalp ringworm usually needs prescription antifungal treatment, and scarring conditions need medical assessment. [3,4]
