PRF Scalp Injections for Hair Loss: What They Are and What to Expect

PRF (platelet-rich fibrin) scalp injections are a newer, “next-gen” cousin of PRP (platelet-rich plasma) used to support hair growth in people with thinning—most commonly androgenetic alopecia (male/female pattern hair loss). PRF is made from your own blood, then injected into areas of thinning to deliver a concentrated mix of platelets and healing signals to the hair follicle environment.

PRF vs PRP: what’s the difference?

Both PRP and PRF start the same way (a blood draw and centrifuge), but PRF is typically processed with different spin settings and without anticoagulants, allowing a fibrin matrix to form. That fibrin matrix is often described as helping provide a more gradual release of growth factors compared with PRP’s faster release profile.

How PRF may help hair follicles

Hair follicles are sensitive to inflammation, reduced blood flow, and signaling changes that cause follicles to “miniaturize” over time. PRF is thought to help by delivering platelet-derived growth factors and cytokines that may support:

• Healthier follicle cycling (supporting the growth phase)

• Reduced micro-inflammation around follicles

• Improved scalp microenvironment for thicker, stronger hair over time

This is the biologic rationale; outcomes vary by person and hair-loss type.

What a PRF scalp injection appointment is like

Most visits follow a similar flow:

1. Blood draw (quick)

2. Centrifuge to prepare PRF

3. Laughing gas to ease the discomfort

4. Small injections into thinning areas

Appointments are typically around 60 minutes.

How many sessions do people need?

We recommend a series up front (often 3–4 sessions spaced about 4–6 weeks apart), then maintenance every few months if you’re responding well.

Who tends to respond best?

PRF is generally best for:

• Early-to-moderate pattern hair loss

• People who want an autologous option (from their own blood)

• People combining it with foundational therapies (e.g., Saw Palmetto, Stinging Nettle if appropriate)

It’s less likely to help in areas with long-standing “slick bald” scalp where follicles are no longer active.

Risks and downsides

PRF is generally considered low-risk because it’s autologous, but common side effects can include temporary swelling, tenderness, itching, bruising, or headache. Infection is uncommon but always possible with any injection procedure.

Bottom line

PRF scalp injections are an emerging regenerative option for hair loss that may offer benefits similar to PRP, with the potential advantage of slower, sustained growth-factor release via a fibrin matrix. Results vary—so the best approach is a proper diagnosis (to confirm your hair-loss type) and a plan that combines PRF with proven fundamentals when appropriate. If you think PRF Scalp Injections could be a good option for you, book a consultation with our Nurse Practitioner to see if it could be right for you.
