Minoxidil and Finasteride Injections: A Revolution in Hair Loss Treatment?

Dre Emilie Bourgeault

Friday, November 15, 2024

Hair loss affects millions of people worldwide, impacting confidence and self-esteem. While solutions like topical or oral minoxidil and oral finasteride remain classic treatments, more targeted alternatives, such as minoxidil and finasteride injections, are emerging as promising options.
What do these treatments involve? What are their advantages? And why should some oral options be avoided? Let’s explore these questions.


Why not oral minoxidil?

Although serious side effects related to the use of oral minoxidil are rare, some individuals may prefer to avoid daily medication due to personal constraints or concerns about potential side effects, such as increased body hair growth or lower limb edema. Additionally, oral minoxidil may be contraindicated in patients with cardiac conditions due to its vasodilatory effects, which can lead to cardiovascular complications (e.g., tachyarrhythmias and others). It is always essential to consult a healthcare professional to evaluate the risks and determine the safest and most effective option.¹

On the other hand, minoxidil injections avoid these side effects by delivering the medication directly to the hair follicles, minimizing systemic exposure. This method is particularly beneficial for patients who are sensitive to or concerned about the side effects of oral minoxidil.

What are Minoxidil and Finasteride Injections?

Minoxidil and finasteride injections involve administering these medications directly into the scalp. Unlike topical solutions, injections allow for deeper penetration, potentially enhancing effectiveness while reducing the need for daily application, which some may find time-consuming or inconvenient.

How do they work?

  1. Minoxidil:

    • Stimulates blood circulation in the hair follicles.

    • Extends the anagen (growth) phase of the hair cycle.

    • Reactivates dormant follicles, promoting hair regrowth.

  2. Finasteride:

    • Blocks the conversion of testosterone into DHT (dihydrotestosterone), a hormone associated with follicle miniaturization.

    • When administered locally, it reduces systemic side effects such as decreased libido or erectile dysfunction, which are, rarely but, linked to its oral use.

Who are these injections for?

These injections are suitable for various forms of hair loss, including:

  • Androgenetic alopecia (male or female pattern baldness).

  • Telogen effluvium, often caused by stress or hormonal changes.

However, they are not suitable for everyone. A consultation with a dermatologist is essential to determine if this treatment meets your specific needs.


Advantages of Minoxidil and Finasteride Injections

  1. Reduced side effects:

    Injections limit systemic effects.

  2. Targeted concentration:

    The medication reaches the hair follicles directly, maximizing effectiveness.

  3. Simplified maintenance:

    Unlike daily oral or topical treatments, injections are administered monthly, typically over 4 to 6 months.

  4. Precise targeting:

    Injections can focus on specific areas of the scalp, making them ideal for localized thinning.

The process is simple and minimally invasive:

What to expect during the procedure?

  • Consultation: A thorough evaluation of your scalp and medical history with a dermatologist.

  • Preparation: The scalp is cleaned.

  • Injection: Using a fine needle, the medication is injected into the affected areas. Each session takes approximately 15 to 30 minutes.

  • Post-procedure care:

    Mild redness or sensitivity is normal and resolves quickly.

    Avoid washing your hair or using styling products for 24 hours.

Are there any risks?

Minoxidil injections are generally well-tolerated, but minor side effects may occur. Mild irritation or temporary sensitivity of the scalp may occur, along with rare allergic reactions. To minimize these risks, it is essential that the injections are performed by a qualified professional.

How long before results are visible?

Hair restoration takes time and patience. Most patients notice early improvements in hair thickness and growth after 3 to 6 months, with full results visible after up to a year.

Conclusion: A Modern Solution for Hair Loss

Minoxidil and finasteride injections are an innovative advancement in hair loss treatment. By avoiding the systemic side effects of oral options and offering a targeted, effective solution, they are an excellent alternative for those seeking to restore hair density.
