Hair loss is a distressing experience for many people, affecting confidence and wellbeing. Among the treatment options available in Australian medical clinics is Platelet-Rich Plasma (PRP) therapy — a minimally invasive procedure that uses your body’s own biological components to support hair follicle health.
In this guide, Hair and Skin Science — an established medical cosmetic clinic network specialising in hair restoration — provides information about PRP hair loss treatment: how it works, who it may be suitable for, what to expect, and how it compares to other options. This resource is intended to inform your decision-making and support a productive conversation with a qualified practitioner.
What is PRP for hair loss?
Platelet-rich plasma (PRP) therapy is a minimally invasive treatment that uses concentrated plasma from the patient’s own blood, which is rich in growth factors, to support hair follicle health. When injected into the scalp, PRP may encourage dormant or weakened hair follicles to become more active, potentially supporting improvements in hair density in appropriate candidates. Individual outcomes vary significantly.
PRP for hair loss is increasingly used in Australia as a non-surgical option with a low risk of adverse reaction for patients with early to moderate hair thinning.
Why is PRP used for hair restoration in Australia?
In recent years, PRP has been considered by a growing number of Australians experiencing hair loss, due to its minimally invasive nature, low risk of adverse reaction, and growing clinical evidence base. Unlike surgical hair transplants, PRP does not require incisions or a significant recovery period for most patients.
Hair and Skin Science is an established medical cosmetic clinic network with clinics across Australia, specialising in hair regrowth and skin rejuvenation. Our qualified Australian doctors and registered nurses provide PRP treatment in a clinical setting, with thorough assessments and individualised treatment plans.
How does PRP hair loss treatment work?
The science behind platelet-rich plasma
Platelets are small blood cells responsible for clotting and releasing growth factors essential for tissue repair. PRP therapy involves drawing a small amount of blood, processing it in a centrifuge to concentrate the platelets, and isolating the resulting plasma.
This platelet-rich plasma contains growth factors and proteins — including platelet-derived growth factor (PDGF), transforming growth factor (TGF), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF) — that may support tissue repair and cellular activity when delivered to the scalp.
When injected into the scalp, PRP may support:
- Activation of hair follicle stem cells
- Increased blood flow and nutrient delivery to follicles
- Collagen production in the scalp
- Reduction of inflammation around follicles
Together, these effects may support the health of weakened hair follicles in some patients, though individual responses vary.
What happens during the treatment process?
- Blood draw — A small amount of blood (usually 10–20ml) is taken from the arm.
- Centrifugation — The blood is spun in a centrifuge to separate platelet-rich plasma from other blood components.
- Scalp preparation — The scalp is cleansed, and a topical numbing agent may be applied for comfort.
- PRP injection — Using fine needles, PRP is injected into areas of thinning or hair loss across the scalp.
- Post-treatment care — Mild redness or sensitivity is common and typically resolves quickly. Most patients return to normal activities the same day.
The procedure takes approximately 45 minutes to an hour, performed in a sterile clinical environment by qualified medical professionals.
Who may be suitable for PRP hair loss treatment?
PRP is most commonly used for patients with:
- Androgenetic alopecia (male and female pattern baldness)
- Diffuse hair thinning across the scalp
- Early to moderate stages of hair loss
- Hair loss associated with stress, hormonal changes, or mild scarring
PRP is generally less appropriate for patients with advanced hair loss or complete follicle loss, where other options such as hair transplantation may be more relevant.
When PRP may not be recommended
Certain conditions may affect suitability, including:
- Severe autoimmune disorders
- Platelet or blood clotting disorders
- Active scalp infection or significant inflammation
- Pregnancy or breastfeeding (consultation required)
- Current use of blood-thinning medications (medical review may be needed)
A thorough consultation with a qualified practitioner is necessary to assess suitability.
What to expect during and after PRP treatment
Treatment schedule
Most patients require an initial course of 3–4 sessions, spaced approximately 4–6 weeks apart. Maintenance sessions every 4–6 months are commonly recommended to support ongoing results.
Results timeline
Individual responses vary considerably. Where improvement is reported, it tends to follow a pattern such as:
- Early changes may be noticed around 8–12 weeks after commencing treatment
- More noticeable hair changes may be visible at 4–6 months
- Assessment of the full effect generally takes 6–12 months
PRP does not alter the underlying genetic predisposition to hair loss. Ongoing maintenance treatment is typically recommended to sustain any benefit achieved.
Post-treatment care
- Avoid washing the scalp or strenuous exercise for 24 hours post-treatment
- Avoid sun exposure and chemical hair treatments for a few days
- Use gentle hair care products as recommended by your practitioner
- Follow any adjunct therapies recommended at consultation
PRP compared to other hair loss treatments
PRP vs PRF and CGF
Platelet-Rich Fibrin (PRF) and Concentrated Growth Factors (CGF) represent evolutions of platelet therapy that use different centrifugation techniques. These approaches may offer different growth factor profiles. Your practitioner can discuss which option may be more appropriate for your situation.
PRP vs hair transplants (FUE, FUT)
PRP is non-surgical and stimulates existing follicles, while hair transplants relocate healthy follicles from a donor area to areas of thinning. Hair transplants require surgery and recovery time. PRP can be used as a complementary therapy alongside hair transplants to support graft survival and scalp health.
PRP combined with other therapies
PRP is sometimes combined with minoxidil, Low-Level Laser Therapy (LLLT), or microneedling as part of a broader treatment approach. Your practitioner will advise on whether combination therapy is appropriate for your situation.
Safety, side effects, and risks
PRP hair treatment is generally well-tolerated. Common, typically mild side effects include:
- Mild scalp redness or swelling
- Temporary soreness or tenderness at injection sites
- Minor bruising in some cases
These symptoms typically resolve within a few days. As with any procedure involving injections, there is a low risk of infection or other complications. Thorough patient assessment and sterile clinical technique minimise these risks.
Every patient at Hair and Skin Science undergoes a medical evaluation before commencing treatment to rule out contraindications.
Cost of PRP hair loss treatment in Australia
The cost of PRP varies by clinic, city, treatment area, number of sessions, and any combined therapies. Hair and Skin Science offers transparent pricing, and we are happy to discuss costs and payment options at your free consultation.
Frequently asked questions
How long does PRP treatment take? Each session typically takes 45–60 minutes.
Is PRP painful? Most patients experience only mild discomfort. Topical anaesthetics are used to minimise pain.
How soon will I see results? Individual responses vary. Where improvement is reported, early changes are typically noticed around 8–12 weeks, with more noticeable results at 4–6 months.
Can PRP treat complete baldness? PRP stimulates existing follicles and is not appropriate for areas where follicles have been entirely lost.
How long do results last? Results vary between individuals. Maintenance sessions are typically recommended to support ongoing benefit.
