PRP treatment for hair loss: procedure, evidence and limitations
What happens during PRP treatment, what studies have shown so far and what you can realistically expect.
PRP treatment is a medical procedure in which platelet-rich plasma is obtained from your own blood and injected into the scalp. It's offered by many dermatology and aesthetic practices, mainly for hereditary hair loss. How the treatment works, what it costs and what studies have shown so far: short and clear.
What is PRP?
PRP stands for "platelet-rich plasma". It's a medical procedure: the plasma contains a lot of platelets and therefore growth factors, which are hoped to have an effect on the hair roots.
How the treatment works
- Blood sample: A small amount of blood is taken, similar to a normal blood test.
- Preparation: The blood is separated in a centrifuge to obtain the platelet-rich plasma.
- Injection: The plasma is injected into the affected areas of the scalp with fine needles.
Several sessions a few weeks apart are usually recommended, often followed by top-up treatments later on.
What you can realistically expect
- Evidence: Some studies report greater hair density with hereditary hair loss, while others find hardly any difference. The studies are usually small, and the procedures vary widely.
- Repetition: For any possible effect to last, the treatment generally has to be repeated.
- Side effects: Pain at the injection sites, redness, swelling and small bruises are possible. As with any injection, there is a small risk of infection.
- Costs: The treatment is generally not covered by public health insurance.
