Platelet-Rich Plasma Therapy (PRP) for Hair Loss


Hair loss is a widespread problem that can severely affect one’s confidence and well-being. Platelet-Rich Plasma Therapy (PRP) is an innovative treatment that utilizes the patient’s blood to promote hair growth and improve scalp health.

PRP therapy is safe and minimally invasive, making it a popular option for individuals seeking effective hair loss treatment. In this article, we will explore the ins and outs of PRP therapy for hair loss.

Understanding Hair Loss and Its Causes

Before delving into the specifics of PRP therapy, it is essential to understand hair loss and its causes. Hair loss can occur due to various factors such as aging, hormonal changes, stress, nutritional deficiencies, autoimmune disorders, and medical treatments like chemotherapy.

Hair loss can be temporary or permanent and affect both men and women. The most common type of hair loss is Androgenetic Alopecia or male/female pattern baldness, which affects up to 50% of men and women worldwide.

How PRP Therapy Works for Hair Loss Treatment?

Hair Loss Treatment with PRP therapy is a minimally invasive procedure that involves taking a small amount of blood from the patient’s arm and processing it in a centrifuge to break up the platelet-rich plasma from other blood components.

The platelets contain growth factors that promote tissue repair, regeneration, and healing. The concentrated PRP is injected into the scalp at the hair follicles’ level to stimulate hair growth and improve the hair’s overall health.

The PRP injection process involves the following steps:

  • Before beginning the PRP injection process, the patient must consult the doctor to discuss their hair loss concerns and understand whether PRP therapy is the right treatment option for them.
  • On the day of the procedure, the healthcare provider will thoroughly clean the patient’s scalp and apply a topical numbing agent to minimize discomfort during the injection process. The healthcare provider will also draw around 30-60 milliliters of blood from the patient’s arm.
  • Once the PRP solution has been prepared, the doctor will use a thin needle to inject it into the scalp at the level of the hair follicles. The injections are typically spaced out across the areas of hair loss or thinning, and the depth of injection may vary based on the extent of the hair loss.
  • After the injections are complete, the patient’s scalp may be tender or sore, and there may be some redness or swelling. The doctor may provide specific aftercare instructions, such as avoiding vigorous activity or washing the scalp for a certain time.
  • Depending on the patient’s response to the treatment, they may require follow-up appointments to monitor their hair growth progress and determine whether additional treatments are needed.

PRP therapy for hair loss is a technique that revitalizes hair follicles by activating dormant stem cells and enhancing blood flow to the scalp. It also boosts the growth of new hair by introducing growth factors into the scalp, which expedite the healing process and promote scalp health.

What to Expect After PRP Therapy for Hair Loss?

After the PRP therapy for hair loss, patients can expect some mild swelling, redness, and soreness at the injection site, which typically resolves within a few hours to a few days. 

It is normal to experience some shedding of existing hair within the first few weeks following the treatment, but this is usually temporary and a sign of new hair growth.

After undergoing PRP therapy for hair loss, patients can expect to witness a range of changes, including:

Improved Hair Growth

PRP therapy stimulates hair follicles to produce necessary proteins and growth factors, leading to new hair growth and increased hair density. This results in visibly thicker and fuller hair, making it an effective method for improving hair growth.

Reduced Hair Shedding

PRP therapy has the potential to reduce hair shedding by improving blood flow to the scalp and strengthening hair follicles, resulting in healthier hair growth. This benefit is attributed to the therapy’s ability to fortify hair follicles and promote optimal hair health.

Increased Hair Strength and Resilience

PRP therapy can improve the hair’s strength and resilience, making it less prone to damage and breakage. This is particularly beneficial for individuals with thinning hair or hair prone to breakage.

Patients should avoid washing their hair or using any hair products for the first 24-48 hours after the treatment to allow the PRP solution to penetrate the scalp and hair follicles.

Most patients require multiple PRP therapy sessions spaced approximately four to six weeks apart to achieve the desired results.

Patients may start noticing visible improvements in hair thickness and quality within three to six months following the treatment. However, the full effects of PRP therapy for hair loss may take up to a year to manifest.

Risks and Side Effects of PRP Therapy for Hair Loss

The use of platelet-rich plasma (PRP) therapy has gained popularity in treating hair loss due to its minimal risk and safety. This treatment involves using the patient’s own blood, thereby reducing the chances of an allergic reaction or transmission of infectious diseases.

However, like any medical procedure, there are potential risks of infection, bleeding, or nerve injury.

Some of the common side effects of PRP therapy for hair loss include redness, mild swelling, and soreness. However, these side effects are usually mild and temporary and subside within a few days. In rare cases, patients may experience hair loss, scalp infection, or scarring.

Who is a Good Candidate for PRP Therapy for Hair Loss?

PRP therapy for hair loss is a suitable treatment option for patients experiencing hair thinning or hair loss. Patients with early-stage hair loss or those looking to prevent hair loss can benefit significantly from PRP therapy.

However, not everyone is an ideal candidate for PRP therapy for hair loss. Patients with active infections, bleeding disorders, or a history of blood clots may not be suitable candidates for the procedure.

Patients taking blood-thinning medications or those with a low platelet count may need to stop taking their medication or undergo additional blood tests before the treatment, as instructed by the attending doctor.


PRP therapy has shown promising results in promoting hair growth and reducing hair loss. With its minimally or non-invasive nature and minimal side effects, PRP therapy offers a safe and effective alternative to traditional hair restoration methods, giving hope to those struggling with hair loss.
