PRP Therapy for Hair Growth: Everything You Need to Know
Hair loss can be a deeply personal concern, impacting not just appearance but also self-confidence. Whether it’s due to genetics, stress, hormonal imbalances, or other health factors, thinning hair can take an emotional toll. In the ever-evolving field of aesthetic treatments, Platelet-Rich Plasma (PRP) therapy has emerged as a revolutionary solution for hair restoration — offering a natural, safe, and effective way to restore hair growth and volume.
What is PRP?
PRP stands for Platelet-Rich Plasma, a regenerative medicine treatment that uses the body’s own healing components to stimulate repair and rejuvenation. The process involves drawing a small amount of your blood, processing it to isolate the plasma enriched with platelets, and then injecting this concentrate into targeted areas.
Platelets are rich in growth factors — bioactive proteins that signal cells to heal and regenerate tissue. These same growth factors that help heal injuries can also stimulate dormant or weakened hair follicles to enter a growth phase, making PRP a powerful tool in hair restoration.
How PRP Works for Hair Growth and Rejuvenation
Hair follicles go through a cycle of growth (anagen), transition (catagen), and rest (telogen). Factors like aging, genetics, or medical conditions can disrupt this cycle, causing hair thinning or loss.
PRP works by:
- Reactivating Dormant Hair Follicles: Growth factors in PRP stimulate the stem cells in hair follicles, encouraging them to shift back into the growth phase.
- Improving Blood Flow: PRP increases blood supply to the hair follicle, delivering more oxygen and nutrients that help hair grow stronger and healthier.
- Thickening Hair Shaft: Not only does PRP promote new hair growth, but it also improves the thickness and density of existing hair strands.
- Extending the Anagen Phase: PRP therapy prolongs the active growth cycle of hair, meaning the hair stays growing for longer periods.
The PRP Process
The entire PRP procedure is minimally invasive and typically takes less than an hour. Here’s a breakdown of what to expect:
- Blood Collection: A small amount of blood (similar to a routine blood test) is drawn from your arm.
- Centrifugation: The blood sample is placed in a centrifuge, which spins it at high speed to separate the plasma from the red and white blood cells.
- Extraction of Platelet-Rich Plasma: The PRP is carefully extracted from the separated layers. This concentrated serum is rich in healing growth factors.
- Scalp Injection: The PRP is injected directly into areas of the scalp where hair thinning or loss has occurred. In some cases, microneedling may be combined to enhance absorption and results.
A numbing agent is used prior to the injections to make it a relatively painless experience
Since PRP uses your body’s own blood, the risk of allergic reaction or rejection is almost negligible, making it a safe and natural therapy.
Benefits of PRP for Hair Growth
1. Minimally Invasive
PRP therapy doesn’t involve any chemicals or synthetic substances. You’re using your own body’s healing components, which reduces the risk of adverse reactions. It’s a non-surgical solution for people seeking a more holistic approach to hair restoration.
2. Stimulates Hair Regrowth
By reactivating hair follicles and boosting the natural hair cycle, PRP stimulates the regrowth of lost or thinning hair. Visible results often begin to appear after the second or third session.
3. Improves Hair Volume and Thickness
PRP doesn’t just grow new hair — it also strengthens the existing ones. The therapy leads to a noticeable improvement in hair texture, volume, and thickness, making your hair appear fuller and healthier.
4. Minimal Downtime
PRP therapy is a quick procedure that doesn’t require hospitalization or extensive recovery time. Patients can typically return to their normal activities the same day.
5. Boosts Scalp Health
In addition to encouraging hair growth, PRP can help improve scalp health by reducing inflammation and improving blood flow, which creates a healthier environment for hair to thrive.
Who is an Ideal Candidate for PRP?
PRP for hair restoration is most effective for individuals who are in the early stages of hair thinning or loss, particularly those with:
- Androgenic alopecia (genetic hair thinning)
- Thinning hair in the crown or along the part line
- Postpartum hair loss
- Hair shedding due to stress or hormonal imbalance
- Those looking to improve density after a hair transplant
However, it may be less effective for those with complete baldness or extensive scarring where hair follicles are entirely inactive.
PRP vs Other Hair Treatments
PRP stands out from other treatments in several ways:
| Treatment | Type | Chemicals Used | Downtime | Results |
|---|---|---|---|---|
| PRP | Natural | None | Minimal | Gradual, long-term |
| Hair Transplant | Surgical | Anaesthesia | 1–2 weeks | Immediate grafted hair |
| Minoxidil | Topical | Yes | None | Temporary, needs continuous use |
| Finasteride | Topical/Oral | Yes | None | Works on hormonal cause only |
PRP can also be combined with these treatments to enhance results — such as after a hair transplant to speed healing, or along with topical minoxidil to boost effectiveness.
How Many Sessions Do You Need?
Most patients require a series of 3 to 4 PRP sessions spaced 4–6 weeks apart for optimal results. Maintenance sessions may be needed every 4–6 months depending on individual response and underlying causes of hair loss.
Your doctor at Krity 360 will assess your scalp condition, medical history, and hair goals to recommend a tailored treatment plan.
What Results Can You Expect?
Results from PRP therapy vary based on factors like age, genetics, hormone levels, and the cause of hair loss. However, most patients experience:
- Reduced hair shedding within 4–6 weeks
- Visible hair thickening by 3 months
- Significant hair volume improvement in 4–6 months
- Continued progress with maintenance sessions
- Consistency and realistic expectations are key.
PRP is not a one-time miracle treatment but a progressive therapy that supports long-term hair health.
