Recently, a new treatment has emerged and become popular among cosmetic experts for treating hair loss: Exosome injections. This technique relies on powerful growth factors derived from stem cells, which work to regenerate hair follicles from within, strengthen them, and stimulate faster new hair growth compared to traditional treatments.Because of this, many people ask Dalily Medical Is exosome therapy really better than PRP (platelet-rich plasma)? Are there any side effects? And what should I do before and after the sessions to maintain the results?
Is Exosome Therapy Suitable for All Types of Hair Loss?
Exosome treatment is most effective for mild to moderate hair thinning and is also highly beneficial for hereditary hair thinning in both men and women. However, in cases of complete or advanced baldness, exosome therapy alone may not be sufficient, and additional solutions such as hair transplantation might be necessary.
When Do Exosome Injection Results Appear?
Results are not immediate:
Initial improvement usually begins 6–8 weeks after the first session.
Final results typically appear within 3–6 months, as hair follicles need time to re-enter the growth phase.
Is the Exosome Session Painful?
Pain is minimal. Most patients only feel a slight tingling or pinprick sensation. Clinics usually apply a topical numbing cream before the session to reduce discomfort.
Can I Dye My Hair After Exosome Therapy?
It is recommended to wait at least 4 weeks before coloring or chemically straightening the hair, as harsh chemicals can irritate the scalp and reduce the treatment’s effectiveness.
Can PRP Be Combined with Exosomes?
Yes. Many people combine PRP (Platelet-Rich Plasma) with exosomes because PRP strengthens hair follicles while exosomes stimulate cellular regeneration. This combination often produces faster and stronger results, especially for hereditary hair loss.
Are There Serious Side Effects of Exosome Hair Injections?
Exosome therapy is considered very safe, with minimal risk of serious side effects since it is derived from safe, body-compatible or closely related sources. Minor temporary side effects may include:
Mild redness
Slight swelling at the injection site
These typically resolve quickly.
How Many Sessions Are Required for Optimal Results?
The number of sessions depends on individual scalp condition and response, but on average:
5–8 sessions are recommended.
Sessions are spaced 3–6 months apart, depending on the doctor’s plan.
When Will I See Results from Exosome Therapy?
Some improvement may be noticed after the second session.
Gradual improvements continue with each session.
Final results usually appear after about 1 year, with reduced hair shedding and increased hair density.
Is Exosome Therapy Permanent?
The longevity of results depends on:
Individual response
The expertise of the physician performing the procedure
Post-treatment hair care
With proper maintenance, results can be long-lasting.
Is Exosome Therapy a Substitute for Hair Transplantation?
Exosomes are not a direct replacement for hair transplants. They can:
Strengthen existing hair
Reduce hair loss
Stimulate new follicle growth
However, for completely bald areas, a hair transplant may still be necessary.
Duration of Exosome Hair Therapy
Exosome therapy is not a single-session treatment. Most patients require 5 or more sessions, with the first 2–3 sessions initiating follicle stimulation. Subsequent sessions gradually improve hair density.
Gradual Results
Hair density, follicle health, and reduced shedding improve over time.
Most patients notice significant improvement after consistent sessions.
Maintenance sessions may be recommended periodically to sustain results.
Exosome Therapy Requires Multiple Sessions
Yes, most cases need 3–6 sessions, spaced 3–4 weeks apart, to enhance hair density and gradually reduce shedding.
Types of Stem Cells Used in Exosome Therapy
Exosomes are primarily derived from different stem cell types, most commonly:
Mesenchymal Stem Cells (MSCs)
Sources: umbilical cord, fat tissue, bone marrow
Benefits:
Reduce scalp inflammation
Promote new follicle growth
Stimulate proteins that strengthen hair
Hair Follicle/Dermal Papilla Stem Cells
Naturally present in hair roots
Play a key role in stimulating hair growth and follicle regeneration
Advantages of Different Stem Cells Used in Exosome Therapy
2) Hair Follicle/Dermal Papilla Stem Cells
Play a key role in the hair growth cycle.
Help accelerate the growth of weak or thinning hair.
3) Umbilical Stem Cells
Source: Umbilical cord/placenta of newborns.
Advantages:
Rich in high-growth factors.
Strengthen hair follicles and increase collagen in the scalp.
4) Adipose-Derived Stem Cells
Source: Body fat, easily accessible.
Advantages:
Stimulate blood circulation in the scalp.
Reduce hair loss and promote new hair growth.
Before starting exosome sessions, a precise diagnosis of the scalp and hair is essential for determining suitability and planning the sessions.
1) Scalp and Hair Assessment
Visual examination of the scalp to evaluate:
Hair density in different areas.
Presence of thinning or bald spots.
Scalp health (dryness, inflammation, dandruff).
Tools like magnifying cameras or TrichoScan devices may be used for detailed follicle analysis.
2) Determining Hair Loss Type
Androgenic alopecia (hereditary hair loss): Gradual thinning at the front or crown.
Stress/nutrition-related hair loss: Typically diffuse and sudden.
Scalp inflammation or skin disease: Accompanied by itching or redness.
3) Follicle Testing (Optional)
Some clinics perform hair follicle tests to measure:
Ratio of dormant vs. active hairs.
Hair thickness and density.
Helps track exosome treatment progress accurately.
4) Lab Tests if Necessary
Blood tests may be ordered to check for deficiencies (iron, vitamin D) or hormonal issues affecting hair growth.
5) Treatment Plan
Number of sessions (usually 3–6).
Interval between sessions (typically 4–6 weeks).
Areas requiring more concentrated injections.
Combining exosomes with other treatments like PRP or fillers if needed.
1) Case Assessment
Doctor examines hair loss severity and identifies areas needing treatment.
2) Scalp Cleaning & Disinfection
Hair is washed and scalp disinfected for better absorption.
3) Exosome Preparation
Serum is loaded into a sterile syringe, sometimes mixed with a carrier solution.
4) Application Methods
| Method | Description |
|---|---|
| Direct Injection | Fine needle injected into weak or bald areas |
| Microneedling / Derma Pen | Tiny channels created to distribute exosomes over the scalp |
5) Scalp Massage
Gentle massage to aid distribution and stimulate blood flow.
Post-Session Instructions
Avoid washing hair for 24 hours.
Avoid heat, sauna, or steam.
No hair coloring or chemical treatments for 1 week.

Tips to Maintain Results After Exosome Hair Treatment
1) Choose a Gentle, Sulfate-Free Shampoo
Avoid SLS and harsh cleansing agents.
Use a shampoo suitable for sensitive scalps to protect hair and follicles.
2) Minimize Heat Styling
Hairdryers and straighteners can weaken hair and cause breakage.
If using heat, always apply a heat protectant beforehand.
3) Avoid Chemical Treatments for a While
Especially during the first 4–6 weeks after exosome sessions.
Chemicals from dyes or straightening treatments can stress follicles and reduce results.
4) Maintain a Balanced Diet
Proteins, iron, zinc, and vitamin D are essential for healthy hair.
Drink enough water daily to keep your scalp hydrated.
5) Use Serums or Scalp Tonics
Especially products containing:
Peptides
Niacinamide
Caffeine
These stimulate blood circulation and help maintain results.
6) Reduce Stress and Mental Pressure
Psychological stress is a major cause of hair loss.
Try relaxation exercises, yoga, or light physical activity.
7) Follow-Up Sessions
Some cases may require a “booster” session every 6 months to maintain hair density and prevent shedding.
8) Avoid Tight Hairstyles
Tight hair ties can pull on follicles, causing mechanical hair loss.
Prefer cotton or satin hair ties to reduce friction.
1) Topical Anesthetic Creams
Usually contain Lidocaine or a Lidocaine/Prilocaine blend (e.g., EMLA cream).
Usage: Applied to the scalp 30–60 minutes before the session under a light covering for absorption.
Benefit: Reduces pain or tingling during injections, making the session more comfortable.
2) Soothing or Moisturizing Ointments for the Scalp
Used by the doctor or recommended a few days before the session, especially if the scalp is dry, damaged, or inflamed.
Important Note: These ointments should be light and free from heavy oils or harsh chemicals, as they may interfere with exosome absorption or cause sensitivity before the injection.
