Scalp Psoriasis and Hair Loss: Treat the Scalp First

Scalp psoriasis can make hair look thinner, particularly when thick scales, scratching and inflammation disturb the hair. In most cases the follicles are not permanently damaged, and hair can grow back once the flare is controlled. If you are considering PRP for thinning hair, first find out whether the loss is from psoriasis, pattern hair loss or both. Treating the inflamed scalp comes before an elective injection course. PRP is not an established treatment for scalp psoriasis.

Is psoriasis actually causing my hair loss?

It can contribute. Psoriasis makes skin cells build up into inflamed, scaly patches. The inflammation and repeated scratching can lead to temporary shedding or breakage. Removing scales roughly may pull hairs out as well. If the hair loss extends well beyond the affected patches, or has a gradual pattern at the temples or parting, there may be a second cause. A clinician should examine the scalp rather than assume every shed hair is explained by psoriasis. NHS: psoriasis

How is scalp psoriasis treated?

NICE recommends a potent corticosteroid applied once daily for up to 4 weeks as initial treatment for adults with scalp psoriasis. A clinician can advise on a formulation that gets through the hair to the skin and show you how to apply it. If it has not controlled the condition after 4 weeks, NICE suggests considering a different formulation and treatments to loosen adherent scale before the steroid. Persistent psoriasis can need a combined vitamin D and steroid product or specialist help. The right treatment depends on the severity, other areas affected and your health. NICE CG153, scalp recommendations

Try not to scratch or pick scales. Soften and remove them gently in the way your clinician recommends. Ordinary dandruff shampoo alone may not control psoriasis, and NICE says not to offer coal-tar shampoo alone for severe scalp psoriasis. NICE CG153

Will the hair grow back?

Often, yes, once the inflammation settles and the scalp is no longer being scratched. Regrowth takes time because hair grows through cycles. A photograph of the parting and any affected patches at the start of treatment helps you judge change over several months rather than day to day.

Can I have PRP while my scalp psoriasis is active?

An inflamed, broken or infected scalp needs assessment and treatment before elective scalp injections. PRP has evidence for some people with pattern hair loss, but that evidence should not be stretched into a claim that it treats psoriasis. Once the flare is controlled, a doctor can assess whether any remaining thinning is pattern hair loss and whether PRP is appropriate. Some people need no PRP at all: removing the inflammatory trigger may be the useful intervention. NICE psoriasis guidance and our PRP treatment overview.

How do I know if it is psoriasis rather than dandruff?

Both can produce flakes and itch. Psoriasis often forms thicker, more sharply defined plaques and may extend beyond the hairline or occur on the elbows, knees or elsewhere. Seborrhoeic dermatitis can look similar, and the two can overlap. That is why an examination matters before you start switching shampoos or booking a hair procedure. Read our dandruff and hair loss guide.

What should I ask at the appointment?

Ask whether the skin findings really are psoriasis, which treatment should touch the scalp rather than just the hair, when to review the response, and whether any separate pattern loss is present. Mention any joint pain or swollen fingers, since psoriasis can coexist with inflammatory arthritis. Bring a list of products and medicines you have tried. If thinning continues after the scalp improves, a clinician can consider other causes and blood tests where appropriate.

What does PRP cost if it is suitable later?

First get the diagnosis right. A premium hair treatment is poor value when the active scalp condition needs a different treatment. If pattern hair loss remains after inflammation is controlled and a clinician finds PRP suitable, The London PRP Clinic lists hair PRP at £450 per session or £1,215 for a course of three. Results vary, and a course should not be sold as a cure for psoriasis. See current PRP treatment and prices.

Frequently asked questions

Q: Can scalp psoriasis cause permanent hair loss?

A: Most psoriasis-related shedding improves after inflammation is controlled. Persistent loss, scarring or shiny bare patches should be assessed because another form of alopecia may be present.

Q: Should I remove the scales to help hair grow?

A: Do not pick or scrape them. Your clinician can recommend ways to soften and gently lift scales so the prescribed treatment reaches the skin without adding damage.

Q: Does PRP treat scalp psoriasis?

A: PRP is not an established treatment for scalp psoriasis. Treat the active scalp inflammation first; a doctor can then assess whether separate pattern hair loss remains and whether PRP is suitable.

Q: How long does scalp treatment take?

A: NICE advises an initial course of a potent scalp corticosteroid once daily for up to 4 weeks, then a review if the condition is not controlled. The plan may change with severity and response.
