What Is PRP Injection?

Platelet rich plasma therapy is widely used nowadays by men and women to have fuller and thicker hair. Although the success rate depends on many factors, most patients have reported positive results and improvements in their hair density, thickness, and overall quality of the hair.

How Platelet Rich Plasma Can Cause Hair Growth?

Here is a bit of a science if you are wondering how PRP works.

The platelets and plasma are taken from the patient’s blood and then injected into the scalp. This procedure results in stimulating hair growth through different mechanisms, such as

  • PRP contains hair growth factors, including platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF). This not only stimulates the hair follicles on the scalp but also enhances tissue regeneration and the formation of new blood vessels (angiogenesis).
  • PRP injection promotes the blood flow in the scalp (because of angiogenesis). More blood flow means more nutrients and oxygen that are necessary for hair growth.
  • The growth factors can also activate dormant follicles. As a result, new hair strands will grow. Plus, they protect the existing follicles by nourishing them. This improves the lifespan of follicles, even the weakened ones.
  • The anti-inflammatory properties of PRP reduce inflammation in the scalp. As inflammation can cause hair loss and prevent the natural hair growth cycle, this is another factor that plays a role in stimulating hair growth.

It’s good to know that PRP is not just used as a hair loss treatment. Different scientific studies have investigated its effects on knee osteoarthritis, tendinopathy, and other clinical applications. This shows that PRP is a perfectly scientific method and patients can trust it more easily.

What Happens During PRP Treatment?


The first thing you need to do is consult with a dermatologist to find out more about what hair loss treatment options can work for your hair loss condition. Besides, your medical history should also be considered by the healthcare professional.

If the conclusion of the consultation session is that PRP injection is the way to go, your blood sample is collected to extract the platelets and plasma. This blood sample collection is like what happens during a simple blood test.

Then, your blood sample will be processed (centrifuged) to separate red blood cells, platelet-poor plasma, and platelet-rich plasma. The platelet rich plasma that is used in PRP injection contains 5 to 10 times more platelets than your normal blood.

Before the injection, you might need to get local anesthesia to reduce pain and discomfort during therapy. But it’s usually a personal choice.

When everything is ready, PRP is injected into different areas of the scalp where hair thinning has happened. This can take around 45 minutes but the exact duration depends on the number of injections the patient needs and some other factors.

While injection is the most common method, PRP can also be applied topically after microneedling. Microneedling means creating microchannels on the scalp with tiny needles to improve the absorption of platelets and growth factors.

Please note that, after injection, some patients experience dizziness and nausea.

PRP Post-Treatment Care, Side Effects, and Follow-Up Sessions


Typically, patients need multiple PRP therapy sessions that happen every several weeks. These follow-up sessions are necessary to achieve the best results and see improvements. The number of sessions and the timing are recommended by your dermatologist depending on your hair loss condition. So, stick to this schedule for an optimal result.

After each PRP session, mild swelling, redness, and discomfort in the scalp are normal. These side effects can last for a few hours up to a couple of days. However, following your healthcare professional’s recommendations for post-treatment care can minimize these minor problems.

PRP post-treatment instructions usually include the following guidelines.

  • Don’t touch or wash your scalp for a minimum of 24 hours to let the PRP absorb well.
  • Don’t use heat styling, harsh shampoos, conditioners, and other products that can irritate your scalp.
  • Protect your scalp from direct sun exposure with a comfortable hat or scarf.
  • Any activities that can lead to excessive sweating should be avoided for two days.
  • Temporary hair shedding can happen after a few weeks which is a normal part of the process and you shouldn’t worry about it.
  • If you experience unusual pain, excessive swelling and redness, and infection, inform your healthcare provider ASAP.

These instructions can be different for each patient.

How Long Does It Take for PRP Treatment to Work?

Again, it varies from patient to patient depending on the underlying cause of their hair loss, its severity, their physiological response to PRP hair treatment, the schedule and consistency of the therapy, etc.

Some may see improvements in their hair quality and thickness or reduced hair shedding only after a few months.

However, noticeable positive effects can happen over time and gradually improve. So, you need to be patient.
