PRP for Hair: A Complete Guide to Platelet-Rich Plasma in Hair Restoration

Hair PRP therapy uses growth factors naturally present in the patient's blood to stimulate the scalp, strengthen hair follicles, and promote hair regrowth.

Hair loss is rarely just a cosmetic issue. For many of our patients, it touches on identity, confidence, and the way they feel about themselves day to day. That is why we focus on solutions that are both medically proven and tailored to each individual. PRP, or Platelet-Rich Plasma, has become one of those essential approaches. Used in medicine for more than 30 years, it now plays a central role in modern hair transplantation and in non-surgical hair loss treatments.

This guide explains what PRP truly is, how it acts on hair regrowth, when it is indicated, and what results you can reasonably expect.

What is PRP (Platelet-Rich Plasma)?

PRP is an autologous concentration of platelets in plasma, produced from the patient's own blood. Platelets are small, non-nucleated blood components whose role goes far beyond clotting: they store and release growth factors and signaling molecules involved in tissue repair, the formation of new blood vessels, and the modulation of inflammation.

In other words, PRP uses the body's own resources to activate its natural regeneration mechanisms — a principle particularly well suited to hair transplantation, where the quality of healing and of the follicular environment directly shapes the final result.

How is PRP prepared?

The protocol is simple, fast, and carried out in-clinic:

1. Blood draw: a small amount of blood is taken from the patient, as for a standard blood test.

2. Centrifugation: the sample is placed in a centrifuge to separate red and white blood cells from the platelet-rich plasma.

3. Collection of the active layer: the concentrated fraction — typically 4 to 8 times the normal platelet concentration — is isolated and prepared for application.

   
   

The entire process, from blood draw to application, takes only a matter of minutes and is performed under strict sterile conditions.

Why has PRP become a standard in regenerative medicine?

Three reasons explain its rise across many medical specialties:

• It delivers a high concentration of growth factors directly to the area being treated.

• It stimulates tissue repair and cellular regeneration.

• Because it is 100% autologous, it is immunologically neutral: no risk of rejection, allergy, or foreign-body reaction.

  
  

PRP has been used for over three decades in sports medicine (muscle, tendon, and joint injuries), orthopedics, dental implantology, ophthalmology, maxillofacial surgery, aesthetic medicine and — increasingly over the past decade — in hair restoration.

PRP in hair transplantation and hair loss treatment

Three concrete actions on hair

Within a hair transplant or anti-hair-loss protocol, PRP acts on three levels:

1. Improving the survival of transplanted grafts during and after surgery.

2. Accelerating healing and reducing visible traces at the donor and recipient sites.

3. Stimulating dormant follicles and improving density and hair shaft quality in patients at the early or middle stages of hair loss.

   
   

How is PRP applied?

Depending on the patient's project, PRP can be used in two main ways:

• During a hair transplant: it is applied directly to the grafts before implantation, and/or injected into the scalp after placement. The goal is to support graft revascularization and optimize the take phase.

• As a non-surgical hair loss treatment: it is delivered through a series of scalp micro-injections, spaced over time. This approach is especially well suited to patients in the early stages of hair loss, or as part of a broader hair loss treatment strategy.

  
  

What patients actually gain

• A higher graft survival rate and faster initial regrowth.

• Reduced post-operative inflammation and accelerated healing.

• Improved density and hair quality in the months following the transplant (most grafts begin producing visible hair between 3 and 6 months after the procedure).

  
  

Safety, side effects and contraindications

A recognized safety profile

Because PRP is derived from the patient's own blood, it is immunologically neutral: there is no risk of rejection, allergy, or foreign-body reaction. Its use is well documented across many surgical specialties, provided it is prepared and applied using rigorous sterile protocols.

Possible side effects

Side effects are uncommon and usually transient. They may include:

• mild pain or discomfort at injection sites,

• minor bruising or temporary swelling,

• very rarely, infection — a risk minimized by strict aseptic technique.

  
  

Contraindications to be aware of

PRP has very few absolute contraindications. Some situations, however, require careful evaluation or may rule out treatment:

• active infection in the area to be treated,

• platelet dysfunction or severe hematologic disorders,

• significant anemia,

• ongoing anticoagulant therapy,

• pregnancy, breastfeeding, active cancer or severe systemic illness.

  
  

A personalized medical consultation remains the only way to determine whether PRP is right for your situation.

The New Hair Graft approach: PRP as part of a premium patient journey

At New Hair Graft, PRP is not an optional add-on: it is a structural part of our hair transplantation protocol. Every patient receives a complete medical evaluation, a protocol tailored to their hair profile, and full support before, during and after the procedure.

"I was anxious about the surgery and the healing process, but the team took the time to walk me through everything. Recovery was faster than I expected, and the first visible results appeared by month four." — Quentin, New Hair Graft patient, FUE transplant + PRP

What defines our approach:

• International medical standards, in a modern and discreet clinical environment in Mauritius.

• Physicians specialized in hair restoration, trained in the most recent PRP and FUE techniques.

• A personalized 12-month follow-up to monitor regrowth and adjust the protocol when needed.

• A patient experience designed as a journey: privacy, comfort and human support at every stage.

  
  

FAQ — Your questions about PRP for hair

Does PRP guarantee hair regrowth? PRP is a supportive therapy: it optimizes the conditions for regrowth and stimulates active follicles. It does not create new follicles where they have fully disappeared. On thinning hair, or alongside a transplant, its effects are well documented.

How many PRP sessions are needed? For a non-surgical anti-hair-loss protocol, 3 to 4 sessions spaced 4 to 6 weeks apart are usually planned during the first year, followed by one or two maintenance sessions per year. When combined with a transplant, PRP is integrated directly into the surgical protocol.

Is PRP painful? PRP is generally very well tolerated. Local anesthesia or a topical numbing agent is used to minimize any discomfort during the injections.

When will I see the first results? Initial improvements in hair quality typically appear after 2 to 3 months, with visible progression up to 6 to 12 months depending on the patient.

Does PRP replace a hair transplant? No. PRP and hair transplantation address different and complementary issues. A consultation will help determine the most suitable solution — or combination — for your specific situation.
