1. What is Mesotherapy?

Mesotherapy is a treatment method that uses a microscopic needle to inject drugs and nutrients directly into the scalp. Unlike topical or oral medications, this method is believed to be more immediately effective because the necessary ingredients can be delivered directly to the hair follicles in the scalp.

• Ingredients injected: Drugs and nutrients used in mesotherapy include
• Vitamins: B vitamins and biotin, which support hair growth.
• Amino Ac ids: Amino acids needed to form hair proteins.
• Minoxidil: An ingredient that stimulates blood flow and activates hair follicles.
• Growth Factors: Factors that promote the regeneration of hair follicles.
• Hyaluronic acid: Helps retain moisture and nutrients in the scalp.

2. Effect of mesotherapy on AGA

Mesotherapy is one of the treatments used to slow the progression of thinning hair due to AGA and to promote the regeneration of hair follicles. In particular, the following benefits are expected

• Improved blood flow to hair follicles: Injected ingredients act directly on hair follicles to promote blood flow. This improves nutrient supply to the hair follicles and promotes hair growth.
• Promotes regeneration of hair follicles: Growth factors and vitamins support the regeneration of hair follicles and promote new hair growth. In particular, it is expected to reactivate hair follicles weakened by the progression of AGA.
• Improved hair thickness and strength: Nutrients injected by mesotherapy help to grow thicker, stronger hair that is less likely to fall out.
• Hormone balance adjustment: Some treatments also use ingredients that inhibit the production of DHT (dihydrotestosterone), which is expected to suppress the progression of AGA by adjusting hormone balance.

3. Advantages of Mesotherapy

• Topical effects: Mesotherapy injects the ingredients directly into the scalp, which makes it easier to achieve topical effects. It works more directly on the hair follicles than taking drugs.
• Little downtime: Mesotherapy is a relatively light treatment, with little to no significant downtime after the procedure. You can return to your daily activities immediately.
• Fewer side effects: Injected ingredients do not spread through the body and act only on the scalp, resulting in fewer systemic side effects.
• Can be used in combination with other treatments: Mesotherapy can be used in conjunction with other AGA treatments such as finasteride and minoxidil for more effective treatment.

4. Disadvantages and cautions of mesotherapy

• Effectiveness varies from person to person: Mesotherapy may vary in effectiveness depending on the progression of AGA and the individual’s constitution. Not all patients will show dramatic improvement.
• Periodic treatments are required: Mesotherapy does not produce significant results in a single treatment, but rather requires regular treatments. Usually, several treatments are performed every few weeks, and then continued treatments are required for maintenance.
• Costly: Mesotherapy is a specialized procedure and can be more expensive than other treatments.
• Mild pain and swelling: Because needles are inserted into the scalp, mild pain, swelling, and redness may be seen after the procedure, but it usually subsides within a few days.

5. Comparison of mesotherapy with other AGA treatment methods

Mesotherapy is superior in that it acts directly on the scalp, unlike oral or topical medications, but is often even more effective when used in conjunction with

• Finasteride or Dutasteride: Aim for a synergistic effect by suppressing DHT production with oral medications and delivering nutrients directly to the hair follicles with mesotherapy.
• Minoxidil: The combination of minoxidil and mesotherapy, which stimulates blood flow, is expected to further promote hair growth.
• PRP therapy: Combining mesotherapy with PRP therapy, which uses ingredients extracted from one’s own blood to activate hair follicles, can enhance regeneration.

Summary

Mesotherapy is one of the effective treatments for AGA (male pattern baldness). By injecting nutrients and drugs directly into the scalp, mesotherapy activates hair follicles and stimulates hair growth. It is particularly suited for patients for whom oral or topical medications are not sufficiently effective, or for patients who desire a localized treatment.

However, since the effects vary from person to person and continuous treatment is required, it is important to combine the treatment with other therapies and consult with a specialist.
