PRP vs Growth Factors for Hair Loss: What’s the Difference and What Works Best?

If you’re researching non-surgical hair restoration options like PRP for hair loss, growth factor therapy or natural hair regrowth treatments in Seattle, you’ve probably run into a lot of technical terms. Two of the most common are Platelet-Rich Plasma (PRP) and growth factor-based therapies, both promising ways to stimulate hair follicles and improve thinning hair without surgery.

In the next few minutes, we’ll clearly explain:

• What PRP is and how it works

• What growth factor treatments are

• The similarities and differences between them

• How to decide which option may be right for you

This comparison is useful whether you’re dealing with early thinning, pattern hair loss or just want a natural way to support fuller-looking hair.

What Is PRP and How Does It Help Hair Loss?

PRP stands for Platelet-Rich Plasma, a treatment that uses your own blood to help stimulate hair growth. In PRP therapy, a small sample of your blood is drawn and processed in a centrifuge to concentrate the platelets (the components of blood that contain powerful growth factors associated with healing and tissue regeneration). The concentrated PRP is then injected into thinning areas of the scalp to deliver these growth factors directly where they’re needed.

Platelets contain a range of growth factors including PDGF, VEGF and EGF. This may help:

• Encourage dormant hair follicles to become active again

• Increase blood flow to follicles

• Improve follicle health, thickness and density

• Slow shedding in many cases

A growing body of clinical evidence suggests PRP can be beneficial for people experiencing pattern hair loss and thinning hair. Some studies show increases in hair count and density after a series of monthly PRP treatments, with minimal side effects.

What Are Growth Factor Treatments?

Growth factors are natural proteins in the body that help cells repair, grow and function properly. They play an important role in healing and tissue health, including the health of hair follicles.

Platelets naturally contain growth factors, which is one reason PRP can support hair growth. Growth factor treatments take this idea a step further by delivering concentrated growth signals directly to the scalp.

In growth factor–based therapies, these signals are applied to thinning areas of the scalp, either topically or through small injections.

PRP vs Growth Factors: Similarities and Differences

Both PRP and growth factor treatments aim to stimulate hair follicles and improve scalp health, but they do it in slightly different ways:

Shared Benefits

• Promote blood flow and nutrient delivery to follicles

• Support natural hair growth cycles

• Can improve thickness and density

• Minimally invasive with little downtime

• Use regenerative biology rather than surgery

Key Differences

Source of Growth Factors:

• PRP uses growth factors that come directly from your own platelets.

• Growth factor therapies may blend or concentrate specific proteins or use advanced biomedical methods to deliver them.

Sessions and Long-Term Access:

• PRP often involves a series of treatments (commonly monthly) plus maintenance sessions.

• Some growth factor protocols aim for fewer treatments over time but may have higher per-session costs.

Medical Evidence:

• PRP has a longer track record and growing clinical evidence for hair regrowth support

• Growth factor therapies have emerged as a potential alternative but vary by formulation.

Which One Is Right for You?

There’s no one-size-fits-all answer. Deciding between PRP and growth factor therapy depends on multiple factors, including:

• Your pattern and stage of hair thinning

• Your goals (slowing loss vs increasing density)

• Budget and treatment commitment

• Medical history and scalp health

At Inclusive Aesthetics, we assess your unique pattern of hair loss as well as goals so that we can recommend the best approach. In some cases, PRP alone may be ideal; in others, a customized growth factor plan can maximize results.

A personalized consultation can help identify whether PRP, growth factor therapy, or a combination is best for your situation.

Final Takeaway: Both Are Valid, Personalized Options

If you’re looking for a minimally invasive, biologically based hair restoration option, both PRP and growth factor therapies offer meaningful potential. PRP is well-established, uses your own biology and is widely regarded in the medical aesthetics community. Growth factor therapies can offer more concentrated stimulation and may be ideal for specific patient goals.

Because every person’s hair loss pattern and biology are different, your best bet is to start with a consultation.
