Platelet rich plasma from your own blood: how it is made, why protocols vary so much between clinics, and what that means for the evidence.

Blood is drawn, spun in a centrifuge to concentrate the platelets, and the resulting plasma is injected back into the skin or scalp. Platelets release growth factors intended to stimulate repair. Preparation methods vary widely between clinics, which makes results and evidence difficult to compare.
A quantity of your blood is drawn into a tube, which is then spun in a centrifuge. Spinning separates the blood by density: red cells at the bottom, a thin layer containing platelets and white cells above them, and plasma at the top. The platelet-rich fraction is drawn off and injected back into the skin or scalp.
Platelets are best known for clotting, and they also contain granules packed with growth factors that are released when they are activated. The rationale is that concentrating and delivering those growth factors into tissue prompts a repair response.
The detail that matters, and that is almost never explained to patients, is that every part of this varies: the volume drawn, the tube system used, the anticoagulant, the centrifuge speed, the spin time, whether a single or double spin is performed, how much white cell content is retained, and the final platelet concentration achieved. Two clinics both offering this treatment may be delivering meaningfully different products.
The variation between protocols is the main reason the published evidence is so hard to summarise.
It means the useful questions are unusually specific.
You are not auditing the science. You are establishing whether the person treating you has engaged with any of it. A practitioner who can answer precisely is in a different category from one who answers with a package name.
Blood is drawn as it would be for any test. The tube is spun for several minutes. The prepared plasma is then injected across the treatment area, or applied into microchannels if combined with needling. The whole appointment usually takes under an hour.
Because the material comes from you, allergic reaction to the product itself is not a concern in the way it is with an injected foreign material. Infection, bruising and the usual injection risks all still apply.
The reasonable expectation is a gradual improvement in skin quality across a course, maintained with periodic treatment. For hair, the reasonable expectation is a contribution to a wider plan rather than a replacement for established treatment.
The unreasonable expectations, which appear regularly in marketing, are dramatic tightening, reversal of significant hair loss, and results from a single session. None of those is supported, and a clinic promising them is describing a product it does not have.
This is the most useful single question for any treatment where the mechanism is described in general terms such as regeneration or rejuvenation. A practitioner who can state the limits clearly is a practitioner worth listening to about the benefits.
Because this involves handling blood, the standards for preparation, labelling and traceability matter. Ask how your sample is labelled and handled, and satisfy yourself that the process looks like a clinical one rather than an improvised one.
Yes. Blood is drawn and processed in the same appointment and the platelet-rich fraction is injected back into your skin or scalp.
Commonly three, four to six weeks apart, then maintenance. A single session rarely produces a durable change.
It is one of the better supported uses, generally alongside conventional treatment rather than instead of it.
Because preparation protocols vary widely: spin speed, spin time, tube system and final concentration all differ, so clinics are not necessarily delivering the same product.
A blood draw, then injections with numbing cream. Uncomfortable rather than painful, with swelling afterwards.
Not to the material itself, since it comes from you. The usual injection risks including bruising and infection still apply.
Gradually across a course, with assessment several weeks after the final session against a standardised photograph.
