PRP for Hair Loss: What It Is, How It Works & What to Expect
Hair loss is one of those concerns that tends to build quietly until it becomes impossible to ignore. Whether you are noticing more hair in the drain, a widening part, or thinning at the temples, the experience is frustrating in a way that feels deeply personal. PRP therapy is one of the more compelling treatment options available right now, not because it is new, but because the clinical evidence behind it has continued to strengthen.
This is what you need to know before booking a consultation.
What Are Platelet-Rich Plasma Injections?
Platelet-rich plasma therapy, commonly called PRP, is a treatment that uses your own blood to stimulate your body's natural repair processes. It is used across several medical fields, including orthopedics and wound healing, and has become one of the more well-supported non-surgical options for hair restoration.
How PRP works in three steps:
- A small amount of blood is drawn from your arm
- The blood is placed in a centrifuge that spins it to separate the platelet-rich plasma from the red blood cells
- The concentrated PRP, which contains a high level of growth factors, is injected directly into the areas of the scalp experiencing thinning or loss
The growth factors in PRP, including platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF), signal the body to increase blood supply to the hair follicles, extend the active growth phase of the hair cycle, and stimulate the production of new, thicker hair strands.
Is Platelet-Rich Plasma FDA Approved?
PRP therapy itself uses equipment and blood processing techniques that are FDA cleared. The treatment is considered safe because it uses your own biological material, which eliminates the risk of allergic reaction or rejection. It is not a drug and does not require FDA drug approval in the traditional sense, but the devices used to process PRP are regulated and cleared for use.
PRP is not covered by Medicare or standard health insurance for aesthetic purposes including hair restoration, as it is classified as an elective cosmetic treatment.
Does Platelet-Rich Plasma Work for Hair Loss?
The clinical evidence is meaningful, particularly for guests in the earlier stages of hair loss.
Clinical studies by Sculptra USA demonstrate 30 to 40% increased hair density after three to six months of treatment, and research indicates that PRP stimulates dormant hair follicles, extends the growth phase, and improves hair thickness in 70 to 80% of patients when administered properly.
Success rates peak with early intervention, with PRP achieving 70 to 80% success rates for patients in early to moderate stages, with best outcomes occurring when treatment starts within the first year of noticeable thinning. Galderma has documneted an average increase of 45.9 hairs per cm² after three initial treatments, with improvements continuing for up to 12 months.
A PubMed meta-analysis published in PMC found that improvement in hair density was reported by 64% of patients and by 46% of clinicians, new hair growth was reported by 57% of patients and 68% of clinicians, and no negative effects were recorded.
The clearest pattern across the research is this: PRP works best when treatment begins early, follows a consistent protocol, and includes maintenance sessions after the initial series.
What Is the Success Rate for Platelet-Rich Plasma Injections?
| Patient Profile | Approximate Success Rate |
|---|---|
| Early stage hair loss (within first year of thinning) | 70-80% |
| Moderate hair loss | 60-70% |
| Advanced hair loss | Lower, varies by individual |
| Female patients | 75-85% satisfaction |
| Male patients | 70-75% satisfaction |
| Patients under 40 | Higher response rates |

These numbers reflect treatment with proper protocols. Results vary based on the degree of hair loss, overall health, and consistency of treatment.
How Much Does Platelet-Rich Plasma Cost?
At milk + honey, PRP hair restoration starts from $775 per session. This includes a consultation with one of our medSPA providers and same-day treatment.
Because PRP requires a series of sessions for optimal results, the full cost of an initial treatment series of three monthly sessions starts from $2,325. Your provider will give you a precise estimate during your consultation based on your individualized treatment plan.
A free consultation is available if you want to discuss whether PRP is the right fit before committing to treatment.
What to Expect From PRP Hair Restoration at milk + honey
The Treatment Protocol
PRP hair restoration at milk + honey follows a structured protocol designed to deliver the most consistent results.
- Initial series: Three monthly treatments spaced approximately four weeks apart
- Maintenance: Sessions every four to six months depending on your individual response and goals
- When to expect results: Most guests begin noticing improvement within two to three months of starting treatment, with peak results appearing between six and twelve months
According to Galderma only 20% of patients experience significant recurrence at one year when maintaining sessions every four to six months, versus significantly higher relapse in those who stop treatment.
Do PRP Injections Hurt?
Most guests describe the experience as mild to moderate discomfort rather than pain. The injections are delivered directly into the scalp, which is a sensitive area, but the needles used are fine and the treatment is relatively quick. Your provider can discuss comfort options during your consultation.
After Your Treatment
It is normal to experience mild tenderness, swelling, or a mild headache following treatment. Most guests return to normal activities the same day with a few precautions:
- Avoid alcohol, blood thinners, and smoking for at least 48 hours
- Avoid strenuous exercise and extreme temperatures for two to three days
- Increase water intake to support the healing process
- Avoid washing the scalp for at least four hours post-treatment
Who Is a Good Candidate for PRP Hair Restoration?
PRP works across a range of hair loss presentations, but results are most predictable for specific guest profiles.
Best candidates:
- Guests experiencing early to moderate hair thinning
- Those within the first year of noticeable hair loss
- Guests with androgenetic alopecia (male or female pattern hair loss)
- Those who prefer a non-surgical, non-pharmaceutical approach
- Guests who can commit to an initial treatment series and ongoing maintenance
Less likely to respond well:
- Advanced hair loss where follicles are no longer active
- Guests with certain autoimmune conditions affecting hair
- Those who cannot commit to the full treatment protocol
Your provider will assess your scalp, review your health history, and confirm whether PRP is the right fit during your consultation. If this is your first time receiving a medSPA treatment at milk + honey, a health history and general consultation are required before treatment can begin.
PRP and Microneedling: A Stronger Combination
PRP is not limited to injection-based hair restoration. When combined with microneedling for skin rejuvenation, PRP is applied topically over the micro-channels created during treatment, allowing the growth factors to penetrate deeper into the skin and accelerate collagen production more effectively than microneedling alone.
Guests who pursue microneedling with PRP typically see improvements in fine lines, scarring, enlarged pores, and overall skin texture. It is a separate application from hair restoration and serves a different guest, but it uses the same biological mechanism: your body's own growth factors doing more of the work.

H2: Your PRP Questions, Answered
What is platelet-rich plasma used for?
In aesthetic medicine, PRP is used primarily for hair restoration and skin rejuvenation through microneedling. It is also widely used in orthopedics for joint and tendon recovery, though that is outside the scope of what milk + honey treats.
How long does platelet-rich plasma last?
Results from an initial PRP series typically last twelve to eighteen months. Maintenance sessions every four to six months significantly extend and preserve those results.
Is platelet-rich plasma safe?
Yes. Because PRP is derived from your own blood, the risk of allergic reaction or rejection is minimal. It has a well-documented safety profile across extensive clinical use. No negative effects were recorded in a PMC meta-analysis covering multiple clinical trials.
Is platelet-rich plasma effective for hair loss?
The clinical evidence supports yes, particularly for early to moderate hair loss. Success rates of 70 to 80% are documented in peer-reviewed research when treatment follows proper protocols and includes maintenance.
How is platelet-rich plasma made?
A small amount of blood is drawn from your arm and placed in a centrifuge. The centrifuge spins the blood at high speed, separating the platelet-rich plasma from the red blood cells. The resulting concentrated plasma is what gets injected into the treatment area.
Does platelet-rich plasma work for hair growth in women?
Yes. Research shows female patients report 75 to 85% satisfaction with PRP for hair restoration, and a 2024 systematic review and meta-analysis published in Skin Research and Technology confirmed PRP's effectiveness specifically for female hair loss. Women tend to respond as effectively as men, and in some studies, satisfaction rates are slightly higher.
How much is platelet-rich plasma at milk + honey?
