PRP vs. PDGF for Hair Loss: Which Is Better for Hair Restoration?
If you’re noticing a widening part, increased shedding, thinning around the temples, or less density than you used to have, you may have come across two regenerative hair restoration treatments: PRP and PDGF.
Both treatments use growth-factor signaling to support existing hair follicles, but they aren’t the same.
So, what’s the difference between PRP and PDGF for hair loss? Is one better than the other? And how do you know which treatment is right for you?
At Boon Aesthetic Wellness in Claremont, CA, we offer both PRP and PDGF for hair restoration. Rather than choosing a treatment based on what’s newest or most popular, we look at your pattern of hair loss, how long it’s been happening, your health history, and what you’re hoping to improve.
Here’s what you should know.
What Is PRP for Hair Loss?
PRP stands for platelet-rich plasma.
Your blood contains platelets, which are involved in clotting as well as cellular signaling and tissue repair. Platelets contain a variety of growth factors, including platelet-derived growth factor.
During a PRP hair restoration treatment, a small amount of your blood is drawn and processed to concentrate the platelet-rich portion of the plasma.
That PRP is then carefully injected into targeted areas of the scalp.
The goal isn’t to implant new hair or create new follicles. PRP provides concentrated platelet-derived signals to the environment surrounding existing follicles.
For appropriate candidates, this may help support healthier hair growth, improve hair density and thickness, and support follicles affected by progressive thinning.
What Is PDGF for Hair Loss?
PDGF stands for platelet-derived growth factor.
PDGF is one of the signaling proteins released by platelets during the body’s natural healing process. It plays a role in cellular communication, tissue repair, and regeneration.
PDGF hair restoration treatments take a different approach from traditional PRP.
Rather than drawing and processing your own blood, a prepared regenerative product containing concentrated PDGF is delivered directly into targeted areas of the scalp.
This provides targeted growth-factor signaling without requiring a blood draw or centrifugation.
PRP vs. PDGF: What’s the Difference?
The easiest way to understand the difference is this:
PRP uses your own platelets and the collection of growth factors they contain.
PDGF provides a concentrated source of specific regenerative growth-factor signaling.
PRP is autologous, meaning it comes from your own body. Because of this, the final concentration and composition can vary depending on the patient, blood-draw technique, and processing system.
PDGF does not require a blood draw and provides a more standardized treatment product.
Both treatments are regenerative approaches to hair restoration, but they get there differently.
Is PDGF Better Than PRP for Hair Growth?
Not necessarily.
One treatment isn’t automatically better for every person experiencing hair loss.
PRP has been studied for certain forms of hair loss, particularly androgenetic alopecia, and has been used in regenerative hair restoration for years.
PDGF represents a newer approach to regenerative aesthetics and is increasingly being used in treatments focused on hair and skin quality.
The decision between the two should take into account your pattern of hair loss, degree of thinning, treatment history, preferences, and overall goals.
At Boon, we offer both because we don’t believe every patient needs to fit into the same treatment protocol.
How Does Regenerative Hair Restoration Work?
To understand what PRP and PDGF can realistically accomplish, it helps to understand what’s happening beneath the scalp.
Each hair grows from a follicle.
Hair follicles naturally cycle through periods of active growth, transition, rest, and shedding. Genetics, hormones, age, stress, illness, pregnancy, nutrition, medications, and other factors can influence this cycle.
In certain forms of progressive hair loss, follicles gradually become smaller and produce finer hairs. This process is known as follicular miniaturization.
Over time, you may notice that individual strands aren’t as substantial as they once were and that more scalp becomes visible.
Regenerative treatments such as PRP and PDGF are intended to support the environment surrounding follicles that are still present.
That’s an important distinction.
Can PRP or PDGF Regrow Hair in Bald Areas?
PRP and PDGF work with existing hair follicles.
They cannot reliably recreate follicles that are no longer viable.
If an area has been completely bald for a long period of time, regenerative injections are less likely to produce meaningful hair growth in that area.
This is one reason early evaluation can be valuable.
If you’re beginning to notice a widening part, thinner ponytail, increased scalp visibility, or gradual thinning around the temples or crown, there may be more existing follicular activity to support than there will be years later.
Hair preservation is often easier than trying to recover hair after significant follicular loss has occurred.
Who Is a Good Candidate for PRP or PDGF Hair Restoration?
Regenerative hair treatments may be considered for men and women experiencing certain forms of hair thinning.
Potential concerns include:
A widening part
Reduced hair density
Increased scalp visibility
Thinning around the temples
Progressive thinning at the crown
Finer individual hairs
Early male pattern hair loss
Female pattern hair loss
Increased shedding
Age-related changes in hair density
However, determining why you’re losing hair is an important part of deciding whether regenerative treatment makes sense.
Why Am I Losing My Hair?
Hair loss isn’t one diagnosis.
There are many potential causes, including:
Genetics
Hormonal changes
Pregnancy and postpartum changes
Perimenopause and menopause
Significant emotional or physical stress
Nutritional deficiencies
Illness
Certain medications
Thyroid disorders
Scalp conditions
Autoimmune conditions
Aging
Androgenetic hair loss
Sometimes more than one factor is contributing at the same time.
If hair loss is sudden, severe, patchy, associated with scalp symptoms, or potentially related to an underlying medical condition, further medical evaluation may be appropriate before beginning cosmetic hair restoration treatments.
At Boon, the goal isn’t simply to inject the scalp. It’s to determine whether regenerative treatment actually makes sense for what’s happening.
PRP vs. PDGF for Female Hair Loss
Female hair loss can look very different from traditional male pattern baldness.
Rather than developing a distinct bald area, many women notice gradual changes such as a widening part, decreased overall density, more visible scalp, or a ponytail that feels smaller than it once did.
Hormonal changes, genetics, stress, pregnancy, postpartum changes, nutrition, medications, and aging can all contribute.
For women who still have viable follicles within areas of thinning, PRP or PDGF may be considered as part of a regenerative hair restoration plan.
The appropriate treatment depends on the cause and pattern of the hair loss, which is why consultation and assessment come first.
What About Postpartum Hair Loss?
Postpartum shedding deserves special consideration because it doesn’t automatically mean you need a hair restoration treatment.
During pregnancy, hormonal changes can keep more hairs in the active growth phase.
After delivery, many of those hairs transition into the shedding phase around the same time. This can make postpartum hair loss feel sudden and dramatic.
For many women, this shedding is temporary and gradually improves as the hair cycle normalizes.
If shedding continues, density isn’t recovering as expected, or pregnancy seems to have uncovered an underlying pattern of hair thinning, further evaluation may be appropriate.
PRP or PDGF may be considered in selected patients, but postpartum shedding shouldn’t automatically be treated simply because it is alarming.
What Is a PRP Hair Treatment Like?
PRP hair restoration begins with a blood draw.
Your blood is processed to separate and concentrate the platelet-rich plasma. The scalp is cleansed, and the PRP is then injected strategically throughout the areas being treated.
Because PRP comes from your own blood, no donor material is involved.
The scalp may feel tender afterward, and temporary redness, swelling, sensitivity, or pinpoint bleeding can occur.
Most patients are able to return to their normal activities relatively quickly.
What Is a PDGF Hair Treatment Like?
PDGF hair restoration also involves a series of targeted scalp injections.
However, because the regenerative product is prepared in advance, there is no blood draw or centrifugation step.
The scalp is cleansed and the product is carefully delivered throughout areas where follicular support is desired.
Temporary tenderness, redness, swelling, or sensitivity may occur after treatment.
How Many PRP or PDGF Treatments Do You Need?
Hair restoration requires patience.
Hair grows slowly and moves through biological cycles, so meaningful changes aren’t expected immediately after an injection.
Many regenerative hair restoration plans involve an initial series of treatments followed by maintenance.
However, there isn’t one treatment schedule that’s appropriate for everyone.
Your recommended number of sessions depends on your starting point, degree and cause of thinning, the regenerative treatment selected, and how your hair responds.
At Boon, treatment plans are personalized rather than automatically placing every patient on the same package.
How Long Does It Take to See Hair Restoration Results?
Hair restoration results develop gradually.
Some patients may notice changes in shedding or the quality of their hair before they notice a visible difference in density.
More noticeable changes generally require several months because new hair needs time to move through its growth cycle and become visible above the scalp.
Consistent photographs can be helpful for evaluating changes because seeing your hair every day can make gradual improvement difficult to recognize.
Are PRP and PDGF Permanent?
PRP and PDGF don’t permanently stop the biological processes responsible for hair loss.
Genetics, hormones, aging, health conditions, and other factors can continue to affect hair follicles over time.
For patients with progressive hair thinning, regenerative treatments are better thought of as part of a long-term hair preservation strategy rather than a permanent cure.
Maintenance treatments may be recommended depending on your individual situation.
So, Should You Choose PRP or PDGF?
You don’t need to decide before your appointment.
In fact, we don’t think you should have to.
Choosing between PRP and PDGF begins with understanding your hair loss.
How long has it been happening?
Is it sudden or gradual?
Where are you losing density?
Are the follicles still active?
Could hormones, nutrition, stress, medication, illness, or another medical condition be contributing?
Once we understand the bigger picture, we can decide whether regenerative hair restoration is appropriate and which option makes the most sense.
Sometimes that’s PRP.
Sometimes it’s PDGF.
And sometimes the right next step isn’t an injection at all.

Frequently Asked Questions About PRP vs. PDGF for Hair Loss
Is PRP or PDGF better for hair loss?
Neither treatment is universally better. PRP uses growth factors released from your own concentrated platelets, while PDGF provides targeted platelet-derived growth-factor signaling without requiring a blood draw. The appropriate treatment depends on your pattern of hair loss and individual goals.
Does PDGF require a blood draw?
No. Unlike PRP, PDGF treatment does not require drawing and processing your blood.
Can PRP make hair thicker?
PRP may help improve hair density and thickness in appropriately selected patients with certain types of hair loss.
Can PDGF help thinning hair?
PDGF is used as a regenerative treatment intended to support the environment surrounding existing hair follicles. Whether it is appropriate depends on the cause and extent of your hair thinning.
Can PRP or PDGF create new hair follicles?
These treatments are intended to support existing follicles. They should not be expected to create completely new follicles in areas where viable follicles are no longer present.
Can women get PRP or PDGF for hair loss?
Yes. Women experiencing certain forms of hair thinning may be candidates for regenerative hair restoration after appropriate assessment.
Can men get PRP or PDGF for hair loss?
Yes. Men experiencing early or progressive hair thinning may also be candidates when viable follicles remain.
How do I know which hair treatment I need?
Start with an evaluation rather than choosing a treatment yourself. Your pattern of hair loss, health history, timeline, and degree of follicular loss can all influence the appropriate treatment plan.
