What is platelet-rich plasma (PRP) hair treatment?

Plasma hair therapy is a non-invasive method that helps replenish hair, increase the thickness of strands, and stimulate the follicles. It involves processing the patient’s blood to extract plasma before injecting it into the target area.

As well as treating hair loss, platelet-rich plasma treatments can be used to relieve chronic pain. This is because the processed plasma can help to reduce inflammation, increase the production of healthy skin cells, and regulate bone regeneration.

How does platelet-rich plasma (PRP) treatment work?

PRP therapy has been around since the 1970s and is an incredibly popular treatment for everything from hair loss to thrombocytopenia.

The science behind plasma hair therapy

When the blood is taken from your body, it is separated into three different parts – platelet-rich plasma, platelet-poor plasma, and red blood cells.

The platelet-rich plasma is full of proteins that are shown to promote regeneration and healing of the hair follicles as well as collagen production, encouraging the growth of healthy, thick strands of hair.

Before the treatment

  • Let your doctor know about any medication you are taking or have recently taken, including prescriptions and over the counter medication.
  • Stay hydrated in the weeks before your appointment to ensure your plasma is as healthy as possible.
  • Do not take aspirin, naproxen, ibuprofen, or any other blood thinners in the week leading up to your appointment.
  • Do not use any hair products the day of your plasma hair therapy, such as hairspray or gel. But you should wash your hair using your regular shampoo.

During the treatment

PRP hair treatment typically takes between half an hour to an hour to complete and is a very straightforward process.

  • Step one – your practitioner will draw a certain amount of blood from your body, usually from your arm.
  • Step two – the blood will be placed in a centrifuge for 12 minutes or so to separate the blood.
  • Step three – Numbing cream or an injection of lidocaine can be applied to the scalp to reduce any discomfort if preferred by the patient. Then the practitioner will then inject platelet-rich plasma into the target areas of your scalp.


As the blood used is taken from the patient, there is a very low risk of infection or other severe side effects. However, bruising, redness, minor soreness, and sensitivity around both the blood draw site and injection site are all common.

These mild symptoms should heal within five days of your treatment. If you do experience discomfort, take paracetamol, but avoid anti-inflammatory medications such as aspirin, ibuprofen and Motin for the initial three days after your platelet-rich plasma hair therapy.

Following treatment, you should:

  • Avoid washing, wetting, or scrubbing the injection site for at least four hours after the procedure.
  • Don’t use hair products for six hours after treatment.
  • Increase your water intake and stay well hydrated for at least a week.

Refrain from using steam rooms, swimming pools and saunas for at least two days.

Alternative treatments

This is far from the only treatment available on the market for hair loss, of course. The exact type of treatment that’s best for you will depend on the extent of your hair loss as well as the reason behind it, but some of the most popular options include:

  • Hair transplants – hair transplants can be lifechanging for some people and are carried out using two different techniques (FUE or FUT) to recreate a full head of hair. Results can take between six to nine months after surgery to show and they are only suitable for people who have permanent baldness – rather than the sparse patches seen with male or female pattern baldness.
  • Lifestyle changes – hair loss can result from stress and vitamin deficiencies. If you believe either may be the case, visit your doctor and see what lifestyle changes you can make to rejuvenate your hair.
  • Mesotherapy – non-surgical and non-invasive, mesotherapy involves a series of microinjections that stimulate hair growth and thickness.
  • Minoxidil – one of very few medications that is proven to help prevent hair loss, Minoxidil is applied directly to the scalp.
