Hair loss is one of the most emotionally charged cosmetic concerns our patients face — and one of the most common. Whether you’re noticing a widening part, thinning at the temples, or a gradual reduction in overall volume, the experience can affect your confidence in ways that go far beyond appearance. The good news? PRP hair restoration in West Hollywood at Dr Refresh Med Spa offers a clinically validated, entirely natural approach to slowing hair loss and stimulating real, lasting regrowth — using the healing power already inside your own body. No surgery. No synthetic chemicals. Just your biology, amplified.
In this comprehensive guide, we’ll walk you through exactly how PRP hair restoration works, what the treatment process looks like, who makes an ideal candidate, and why Dr Refresh is the trusted choice for patients across West Hollywood and greater Los Angeles seeking natural hair regrowth solutions.
What Is PRP Hair Restoration?
PRP stands for Platelet-Rich Plasma — a concentration of your own blood’s growth factors, isolated and re-injected into areas of the scalp experiencing hair thinning or loss. Platelets are the component of blood responsible for wound healing and tissue regeneration. When concentrated and delivered directly into hair follicles, they create a highly anabolic environment that revives dormant follicles, extends the active growth phase of existing hairs, and stimulates the production of new, thicker strands.
PRP therapy is not a new concept — it has been used in orthopedics, sports medicine, and wound care for decades. Its application in hair restoration is backed by a growing body of clinical research. A landmark study published in the Journal of Cutaneous and Aesthetic Surgery (NIH) demonstrated statistically significant improvements in hair count, thickness, and root strength following a series of PRP scalp injections. The American Academy of Dermatology recognizes PRP as an emerging and promising treatment option for androgenetic alopecia and other forms of hair thinning.
What makes PRP uniquely appealing is its autologous nature — because the plasma comes from your own blood, there is virtually no risk of allergic reaction, rejection, or adverse immune response. It is one of the most biocompatible treatments in modern aesthetic medicine.
How PRP Works for Hair Loss
To understand why PRP is effective for hair restoration, it helps to understand what causes hair loss in the first place. The most common form — androgenetic alopecia (male and female pattern baldness) — is driven by the hormone dihydrotestosterone (DHT), which progressively miniaturizes hair follicles over time. As follicles shrink, they produce thinner, shorter, and eventually no hair at all. Additional causes include hormonal fluctuations, nutritional deficiencies, chronic stress, autoimmune conditions (such as alopecia areata), and scalp inflammation.
PRP addresses hair loss through several simultaneous biological mechanisms:
- Growth Factor Delivery: Platelets are packed with growth factors including PDGF (platelet-derived growth factor), VEGF (vascular endothelial growth factor), EGF (epidermal growth factor), and IGF (insulin-like growth factor). When injected into the scalp, these signals stimulate follicular stem cells and dermal papilla cells — the root drivers of hair production.
- Angiogenesis: PRP promotes the formation of new blood vessels around the hair follicle, improving the delivery of oxygen and nutrients to the follicle matrix — the cellular engine behind hair growth.
- Prolonged Anagen Phase: PRP extends the anagen (active growth) phase of the hair cycle, meaning each follicle spends more time actively producing hair before entering the resting and shedding phases.
- Follicle Rescue: Miniaturized follicles that are still alive but no longer actively producing hair can often be reactivated by PRP’s growth factor cascade, recovering follicles that would otherwise be lost permanently.
- Reduced Scalp Inflammation: Chronic low-grade scalp inflammation is a contributing factor in many types of hair loss. PRP has anti-inflammatory properties that create a healthier environment for follicular activity.
The result is a multi-front biological intervention that simultaneously protects existing hair, reactivates dormant follicles, and lays the groundwork for denser, healthier growth over time.
Benefits of PRP Hair Restoration
PRP hair restoration has earned its place as one of the most sought-after non-surgical hair loss treatments available. Here’s why our West Hollywood patients are choosing it:
- 100% Natural: PRP uses only your own blood — no synthetic drugs, no foreign chemicals, no transplanted tissue. It’s the most natural hair restoration method available short of lifestyle changes.
- Non-Surgical: No incisions, no stitches, no general anesthesia, and no surgical recovery. The treatment is performed entirely via injection in an outpatient setting.
- Clinically Proven: Multiple peer-reviewed studies support PRP’s efficacy for androgenetic alopecia and other forms of hair thinning, with measurable improvements in hair density, shaft thickness, and scalp coverage.
- Minimal Downtime: Most patients return to normal daily activities the same day or the following day. There is no prolonged recovery period.
- Complements Other Treatments: PRP works synergistically with topical treatments like minoxidil, oral medications like finasteride, and hair transplant surgery — enhancing and accelerating results across the board.
- Suitable for Men and Women: Both male and female pattern hair loss respond well to PRP. It is also used for conditions such as alopecia areata, traction alopecia, and post-partum hair shedding.
- Long-Term Results with Maintenance: After completing an initial series, many patients enjoy sustained improvement with just 1–2 maintenance sessions per year.
- No Systemic Side Effects: Unlike oral hair loss medications, PRP carries no systemic side effects such as hormonal disruption or sexual dysfunction — a major reason many patients seek it out specifically.
Who Is a Good Candidate for PRP Hair Restoration?
PRP hair restoration is not a universal solution for every type or stage of hair loss — but it is highly effective for a wide range of patients. You are likely an excellent candidate if you:
- Are experiencing early to moderate androgenetic alopecia (male or female pattern baldness)
- Have thinning hair but still have active — if miniaturized — follicles in the affected area
- Are dealing with diffuse thinning, a widening part, or reduced hair density
- Have been diagnosed with alopecia areata (patchy hair loss)
- Are experiencing post-partum hair shedding that hasn’t resolved naturally
- Want to enhance the results of a prior hair transplant procedure
- Prefer a natural, non-pharmaceutical approach to hair loss management
PRP is generally less effective in areas where the scalp is completely smooth and follicles are no longer present — in these cases, the growth factors have no follicular cells to stimulate. For patients with advanced hair loss, PRP is most powerful as part of a combined approach that may include hair transplant surgery followed by PRP maintenance. Our providers will honestly assess your scalp during your consultation and recommend the right treatment pathway for your specific situation.
PRP may not be appropriate for patients with active blood disorders, those on blood-thinning medications, or individuals with certain autoimmune conditions. A thorough medical history review at your consultation will confirm your candidacy. Learn more about the full range of restorative treatments available at our West Hollywood med spa services page.
The PRP Hair Restoration Treatment Process at Dr Refresh
Step 1 — Complimentary Hair Loss Consultation
Your PRP journey at Dr Refresh begins with a detailed scalp and hair loss consultation. Your provider will assess your hair loss pattern, density, scalp condition, and overall health history. We use this information to determine whether PRP is the right treatment for you, set realistic expectations, and design a treatment plan — including session frequency and any complementary therapies that may enhance your results.
Step 2 — Blood Draw
On the day of your treatment, a small amount of blood — typically 20–60 mL, similar to a standard lab draw — is collected from your arm. This is quick, straightforward, and causes minimal discomfort. The blood is then placed into a specialized centrifuge device.
Step 3 — Centrifugation and PRP Preparation
The centrifuge spins the blood at high speed for 10–15 minutes, separating it into its component layers: red blood cells, platelet-poor plasma, and the highly concentrated platelet-rich plasma we use for treatment. The PRP layer is carefully extracted using a sterile syringe, resulting in a golden-colored solution containing platelet concentrations 5–10 times higher than found in normal blood.
Step 4 — Scalp Preparation and Numbing
The treatment area of the scalp is cleansed, and a topical numbing cream is applied for 20–30 minutes prior to injection to maximize your comfort. Most patients find the procedure very tolerable with proper numbing.
Step 5 — PRP Injection
Your provider will use a fine-gauge needle to administer the PRP in a series of micro-injections across the thinning or affected areas of the scalp. Injections are strategically placed at the level of the hair follicle — typically 0.5–1 cm apart across the treatment zone. The entire injection process takes approximately 20–30 minutes. Most patients describe a mild pressure sensation with occasional brief stinging — very manageable, especially with the topical numbing in place.
Step 6 — Post-Treatment and Recovery
Immediately after treatment, the scalp may feel mildly tender or look slightly red — both completely normal and typically resolve within 24–48 hours. You may resume normal activities the same day, though we recommend avoiding vigorous exercise, swimming, and direct sun exposure for 24 hours. Do not wash your hair for at least 6 hours post-treatment to allow the PRP to absorb fully into the scalp tissue.

PRP Hair Restoration Results: What to Expect and When
One of the most important things to understand about PRP hair restoration is that results are progressive — the treatment works with your biology, which operates on its own timeline. Here’s a realistic framework for what to expect:
- Months 1–2: Reduced shedding is often the first sign the treatment is working. The inflammatory cycle driving follicle miniaturization begins to slow. Existing hairs may feel thicker or stronger.
- Month 3: Early regrowth of fine, new hairs becomes visible in previously thinning areas. Hair density begins to visibly improve for many patients.
- Months 4–6: More pronounced increases in hair count, thickness, and scalp coverage. This is typically the window of most dramatic visible improvement after an initial 3-session series.
- Months 6–12: Results continue to mature. Hair texture improves, and the overall appearance becomes noticeably fuller and more uniform.
- Year 1 and beyond: Maintenance sessions every 6–12 months sustain and build upon initial results, keeping follicles in an optimal growth state long-term.
Individual results vary based on the degree of hair loss, underlying cause, age, hormonal health, and consistency of the treatment protocol. Patients who combine PRP with evidence-based topical treatments and good scalp hygiene consistently achieve the best outcomes. Our team at Dr Refresh will check in on your progress and adjust your plan as needed throughout your treatment journey.

Frequently Asked Questions About PRP Hair Restoration in West Hollywood
How many PRP sessions will I need?
Most patients complete an initial series of 3 sessions spaced 4–6 weeks apart to establish a strong foundation of follicular stimulation. After the initial series, a maintenance session every 6–12 months is typically recommended to sustain results. Patients with more advanced thinning may benefit from a slightly extended initial series — your provider will map out the right plan at your consultation.
Is PRP hair restoration painful?
Discomfort is minimal when topical numbing cream is applied prior to injection, which is standard practice at Dr Refresh. Most patients describe the sensation as mild pressure or brief stinging during injection. The procedure is well-tolerated by the vast majority of our patients, including those with low pain thresholds.
How long do PRP hair restoration results last?
Results from an initial PRP series can last 12–18 months before maintenance is needed. The longevity of results depends on the underlying cause of hair loss, hormonal status, lifestyle, and whether complementary treatments are used. Annual or biannual maintenance sessions are the most effective way to preserve and continue building on your results over time.
Can PRP be combined with hair transplant surgery?
Yes — PRP is frequently used in conjunction with hair transplant procedures. It can be applied during transplant surgery to enhance graft survival rates, and used post-operatively to accelerate healing and stimulate growth of transplanted follicles. For patients who have previously had a transplant, PRP maintenance sessions can also strengthen and thicken the transplanted hairs over time.
Does PRP work for women with hair loss?
Absolutely. Female pattern hair loss (androgenetic alopecia in women), diffuse thinning, post-partum shedding, and alopecia areata all respond well to PRP. Women often see excellent results because female hair loss tends to involve diffuse miniaturization rather than complete follicular death — meaning more viable follicles are present and available for PRP stimulation.
Are there any side effects from PRP hair restoration?
Because PRP uses your own blood, the risk of allergic reaction or systemic side effects is extremely low. Common, temporary local effects include mild scalp tenderness, redness, and occasional minor swelling or bruising at injection sites — all of which resolve within 24–72 hours. Serious complications are rare when treatment is performed by a trained provider in a clinical setting.
