What should you know about plasma rich protein injections for hair loss?

A clinician takes a blood sample, processes it to concentrate platelets in plasma, and injects the preparation into selected scalp areas. Platelets release signals involved in tissue repair, but hair shedding or thinning can arise from different conditions, including pattern hair loss, alopecia areata, telogen effluvium, traction alopecia, or scalp ringworm.

PRP is not a substitute for identifying inflammation, infection, scarring, nutritional problems, hormone-related changes, or medicines that may be affecting the hair cycle. The treatment plan and follow-up should match the suspected cause.

Ask for a scalp examination and a clear explanation of the diagnosis before booking injections. Share when shedding began, whether it is diffuse or patchy, family history, recent illness or stress, hairstyles that pull on the roots, scalp symptoms, and all medicines or supplements. Your clinician may discuss other treatments, such as finasteride for selected patients, depending on the diagnosis and your health.

Follow instructions about washing the scalp and medicines. After treatment, use the advised scalp care, avoid scratching injection sites, and attend the planned review so the response and ongoing hair loss can be reassessed.

Seek medical advice for painful or rapidly spreading hair loss, pus, marked redness, thick scale, broken hairs with swelling, bleeding, or a very tender scalp. Sudden patchy loss, eyebrow loss, or smooth shiny areas can also require prompt assessment because the cause may need treatment beyond injections.

Ask what type of hair loss is suspected, why PRP fits that diagnosis, how progress will be measured, what other treatments are available, and what findings would change the plan.
