Hair Growth Injection Guide: AMT vs PRP vs Filorga NCTF – One of Them Isn’t Even a Real Hair Growth Injection?

Having hair versus not having hair makes a huge difference—hair loss and balding can deliver a serious blow to one’s appearance and confidence! With rising work stress, changes in diet, and aging, hair loss is becoming increasingly common and is a sensitive issue for many. Some even resort to wigs or hairpieces! This not only affects appearance but also self-esteem. If you’re facing thinning hair and long to restore your full head of hair, hair growth injections are a non-invasive option that’s drawing growing attention. But do they really work? Are there side effects? Let’s break it all down for you!

1

What Are Hair Growth Injections? Are They Clinically Certified? A Deep Dive into the Mechanism and Efficacy

Before we dive into hair growth injections, let’s look at how common hair loss really is. Statistics show that hundreds of millions of people worldwide are actively seeking treatments to restore their hair. Among the many options, hair growth injections have emerged as a promising new technology. Their key advantage lies in directly targeting the scalp to stimulate hair follicles at the root.

What Are Hair Growth Injections? Key Benefits, Lasting Results, and Safety

Put simply, hair growth injections are non-surgical treatments that inject specific active ingredients directly into the upper or dermal layers of the scalp. This stimulates the hair follicles to restart hair production and increases hair volume.

This direct injection method bypasses the systemic side effects of oral medications and the poor absorption issues of topical shampoos and serums, delivering active ingredients precisely where they’re needed most. This means the treatment is more concentrated and effective!

The 3 Most Popular Hair Growth Injections in Hong Kong and Their Technologies

Although there aren’t many types of hair growth injections on the market, here are three that are getting the most buzz in Hong Kong:

1. AMT Hair Growth Injection (Perfect Medical)

The AMT hair growth injection, offered by Perfect Medical, is based on an innovative hair revitalization technology. It works by extracting and concentrating growth factors from your own hair follicles—typically from cells surrounding the follicles—and injecting these concentrated growth factors back into targeted areas of the scalp.

These growth factors reactivate dormant or shrunken hair follicles and promote new capillary formation, supplying follicles with the nutrients they need to regrow hair. Since the ingredients come from your own body, the risk of allergic reaction or rejection is greatly reduced. The results tend to look more natural and last longer.

2. Filorga NCTF 135HA Injection

You’ve likely heard of the “Little Red Riding Hood” injection—it’s popular around the world. Its main ingredients include non-crosslinked hyaluronic acid and a blend of vitamins, amino acids, minerals, and coenzymes.

Its primary function is to improve the scalp’s microenvironment. By hydrating and nourishing the scalp, it helps soothe dryness and sensitivity while creating optimal conditions for hair growth. A healthier, more hydrated scalp supports stronger, shinier, and more elastic hair. However, note: this injection focuses more on scalp care than true follicle stimulation—it’s not a direct hair growth treatment!

3. PRP Hair Growth Injection (Platelet-Rich Plasma)

PRP hair growth therapy applies regenerative medicine principles to hair restoration. It involves drawing a small amount of the patient’s blood, processing it through centrifugation to isolate platelet-rich plasma (PRP), and injecting this back into the scalp.

The PRP contains multiple growth factors such as PDGF, TGF-β, and VEGF, which activate stem cell proliferation and differentiation in the hair follicles, promoting hair growth and extending the growth phase. PRP also enhances scalp blood circulation, increasing the delivery of oxygen and nutrients to hair follicles—nurturing hair from the inside out.

The 5 Major Benefits of Hair Growth Injections for Follicle Revival

Hair growth injections offer multi-dimensional improvements for hair loss:

1. Revitalize Dormant Follicles: The core function—reactivating hair follicles that have become dormant or atrophied, encouraging them to produce hair again.
2. Extend Hair Growth Phase: By supplying growth factors and nutrients, they help hair stay in the growth phase longer and reduce premature shedding.
3. Enhance Scalp Blood Circulation: Boosting microcirculation ensures hair follicles get ample oxygen and nutrients for healthy development.
4. Improve Hair Thinning, Receding Hairline, and Male Pattern Baldness: Targeted follicle rejuvenation improves density and coverage in affected areas.
5. Thicker, Healthier Hair: New hair tends to grow in stronger and more resilient, improving both volume and texture.

Am I a Suitable Candidate for Hair Growth Injections? Indications and Contraindications

While promising, hair growth injections aren’t for everyone. It's vital to assess your health condition, follicle status, and expectations before treatment.

Best candidates:

Those with partially atrophied follicles: The most important factor—if your scalp is completely bald and smooth, it likely indicates dead follicles. In such cases, hair transplants may be a better option.

Those with thinning crown, receding hairline, male pattern baldness, postpartum hair loss:

○ Crown thinning: Hair growth injections can reactivate weakened follicles and stimulate new growth.
○ Receding hairline and M-shaped forehead: Often due to male pattern baldness, early-to-moderate cases may benefit from follicle stimulation at the hairline.
○ Androgenetic alopecia: Effective for mild-to-moderate cases; the treatment can counteract hormonal effects and nourish follicles.
○ Postpartum hair loss: Often caused by hormone changes, injections can help shift hair from resting to growth phase more quickly.
○ Stress-induced or nutritional hair loss: Improves microcirculation and directly delivers nutrients to hair follicles.

Those seeking non-invasive hair loss treatment: Ideal for individuals unwilling or unable to undergo hair transplant surgery.

Those looking to improve hair quality and volume: Even without severe hair loss, it’s suitable for enhancing shine, density, and resilience.

6 Types of People Who Should Avoid Hair Growth Injections

To ensure safety and avoid complications, the following individuals are generally advised not to undergo hair growth injection treatments:

1. Pregnant or breastfeeding women: Due to potential risks to the baby.
2. Autoimmune disease patients (e.g. lupus, rheumatoid arthritis): These conditions may affect healing and immune response to the injected substances.
3. People with bleeding disorders or on blood thinners: Injection may cause excessive bruising or bleeding.
4. People with scalp conditions like eczema, rosacea, severe dandruff, psoriasis, or skin cancer.
5. People with open wounds or active infections on the treatment area.
6. Individuals allergic to injection ingredients: Always disclose allergies and undergo patch testing if needed.

What to Expect During a Hair Growth Injection Treatment

A typical session includes:

1. Consultation & Assessment: To tailor the treatment to your hair condition.
2. Scalp Cleansing & Disinfection: Prevents infection at injection sites.
3. Topical Anesthesia (if needed): Depending on pain tolerance, numbing may be applied.
4. Injection: Hair growth solution is injected into specific scalp areas using fine needles or microneedling techniques.
5. Post-Treatment Scalp Care: A soothing solution may be applied, and aftercare instructions are provided.
6. Course of Treatment: Usually involves multiple sessions spaced weeks apart for optimal results.

Post-Treatment Golden Care Strategy: Boost Satisfaction from 24 Hours to 1 Month

Post-treatment care and long-term maintenance habits are key to prolonging the effects of hair growth injections. Here's your detailed golden maintenance plan:

1. Immediate Post-Treatment Care (Within 24–48 Hours):

• Avoid Washing Hair: Refrain from washing your hair or getting your scalp wet within the first 24 hours after injection to prevent infection and allow better absorption of the injected ingredients. Some clinics recommend extending this to 48 hours.
• Avoid Intense Exercise: Steer clear of heavy sweating and intense workouts to reduce the risk of infection and irritation at the injection site.
• Avoid Touching or Rubbing the Area: Treat your scalp gently. Don’t touch, scratch, or massage the injection area to prevent redness, swelling, or infection.
• Monitor the Area: Keep an eye on any unusual symptoms like redness, pain, or discharge at the injection site. Contact your clinic promptly if any discomfort arises.

2. Mid-Term Care (One Week to One Month After Treatment):

• Gentle Cleansing and Care: Avoid using shampoos or hair products with harsh chemicals during the first week. Use gentle, silicone-free, pH-balanced shampoos and wash your hair with lukewarm water.
• Avoid Hair Dyeing or Perming: Refrain from chemical treatments like dyeing or perming for at least one week, as these can irritate the scalp and interfere with follicle recovery.
• Sun Protection: The scalp may be more sensitive post-treatment. Protect it from direct sunlight by wearing a hat or using physical sun protection.
• Attend Follow-Up Appointments: Follow your doctor’s advice for follow-ups to monitor hair growth and scalp recovery. Treatment plans may be adjusted accordingly.

3. Long-Term Maintenance (One Month and Beyond):

• Maintain a Healthy Diet: Balanced nutrition is crucial for healthy hair growth. Increase intake of protein-rich foods (e.g., fish, eggs, legumes), iron (e.g., red meat, spinach), zinc (e.g., nuts, seafood), biotin (vitamin H in egg yolks, liver, nuts), and vitamins B, C, and E. These are all essential for hair structure and growth.
• Get Adequate Sleep: Avoid staying up late and learn to manage stress through yoga, meditation, exercise, or hobbies—chronic stress is a major cause of hair loss.
• Avoid Smoking and Limit Alcohol: Tobacco restricts blood flow to the scalp, while alcohol may deplete essential nutrients—both hinder hair growth.
• Continue Using Supportive Products: Under medical advice, use topical hair growth tonics or oral supplements (e.g., biotin, multivitamins) to support long-term follicle health.
• Regular Scalp Care: Use hair care products suitable for your scalp and regularly cleanse and massage the scalp to keep it healthy.
• Avoid Excessive Styling: Minimize the use of high-heat styling tools and avoid overly tight hairstyles that can physically damage hair follicles.

Hair Growth Injection Frequency and Longevity of Results

Hair growth injections are a phased treatment process, not a one-time solution.

• Initial Treatment Phase: Typically involves injections every 1–2 weeks. A full course usually includes 4–8 sessions, adjusted based on the severity of hair loss, follicle response, and physician’s evaluation.
• Maintenance Phase: After the initial course, doctors may recommend moving to a maintenance phase, with sessions spaced every 1–3 months or longer to sustain results.
• Duration of Effects: Results usually last 1–2 years, depending on the cause of hair loss, lifestyle habits, and adherence to post-treatment care. Effects will gradually diminish if treatment stops, but it typically won’t accelerate hair loss—new hair growth may just slow to pre-treatment levels.

Four Things to Check Before Buying Hair Growth Injections

When considering hair growth injection treatments, choose wisely. These are critical factors:

1. Certification and Credentials: Confirm the clinic or medical aesthetics provider is legally licensed, and the injection products have official certifications (e.g., FMA, CE) to ensure quality and traceability.
2. Medical Professionalism: The injector must be a certified medical professional with clinical experience. Avoid recommendations or procedures from non-medical personnel.
3. Transparent Pricing: Steer clear of unclear or overly low pricing, which may indicate poor-quality products or services.
4. Don’t Be Penny-Wise, Pound-Foolish: Especially avoid buying second-hand injections on platforms like Carousell. These products have unknown sources, storage, and expiration, which may lead to infection, allergic reactions, or ineffectiveness—posing serious health risks.

Hair Growth Injections vs Hair Transplant Surgery

Hair Transplant Surgery:

• How It Works: An invasive procedure that extracts healthy follicular units from donor areas (usually the back of the scalp) and implants them in thinning or balding areas.
• Pros: Most dramatic and long-lasting results. Ideal for severe hair loss or dead follicles. One procedure can provide noticeable improvements.
• Cons: Invasive, carries surgical risks (infection, bleeding, anesthesia). Requires careful aftercare. Limited number of surgeries possible in a lifetime. High cost.
• Best For: Those with dead follicles, large balding areas, and a strong desire for fast, permanent results—with a sufficient budget.

13

Hair Growth Injections vs Topical Solutions / Oral Medication

Topical Hair Growth Products (e.g., Minoxidil):

• Mechanism: Expands scalp blood vessels to enhance follicle blood flow and stimulate hair growth.
• Pros: Easy to use, relatively affordable.
• Cons: Requires long-term use to maintain results. Hair may fall out again if stopped. Some experience scalp irritation or itching. Limited absorption to deep follicles.
• Best For: Mild hair loss sufferers or as supplementary treatment.

Oral Medication (e.g., Finasteride):

• Mechanism: Targets male pattern baldness by inhibiting androgen effects on follicles to slow hair loss.
• Pros: Convenient; systemic effect.
• Cons: Must be taken long-term. May cause side effects like sexual dysfunction. Not suitable for women or non-hormonal hair loss.
• Best For: Men diagnosed with androgenetic alopecia.

14

Medically Recognized Hair Growth Treatments

Low-Level Laser Therapy (LLLT):

• Mechanism: Uses specific wavelengths of low-level laser light to stimulate follicle cell activity and promote hair growth.
• Pros: Non-invasive, painless, one of the three globally recognized hair loss treatments (the others being prescription oral medications and topical solutions).
• Cons: Milder effects due to its non-invasive nature; requires long-term consistency.

Microneedling:

• Mechanism: Uses rollers or electric pens with tiny needles to create micro-channels on the scalp, enhancing microcirculation and growth factor release while improving absorption of topical treatments.
• Pros: Relatively affordable; enhances effectiveness of other treatments.
• Cons: Improper use may cause infection; pain levels vary by individual.
