Hair loss affects millions of men worldwide, often beginning earlier than expected. Receding hairlines, crown thinning, and visible scalp exposure are common signs of androgenetic alopecia, more widely known as male pattern baldness and female pattern hair loss.
One of the most established medical treatments available today is oral finasteride, a prescription medication used to slow hair loss progression and help preserve existing hair density.
However, modern hair restoration is no longer limited to oral medication alone. At Clinique de Paris, treatment strategies often include topical scalp-based therapies and combination approaches using Minoxidil and Finasteride, designed to target hair loss through multiple biological pathways.
Understanding the cause and progression of hair loss remains the foundation of effective treatment.
What Is Oral Finasteride?
Oral finasteride is a prescription medication used to treat male pattern hair loss or androgenetic alopecia and benign prostatic hyperplasia (BPH). It works by inhibiting the5-alpha-reductase enzyme, reducing dihydrotestosterone (DHT) levels to prevent hair follicle miniaturization and prostate enlargement.
It works by reducing levels of dihydrotestosterone (DHT), the hormone responsible for follicle miniaturization in genetically predisposed individuals.
By lowering DHT, oral finasteride helps slow the progression of hair thinning and supports long-term preservation of existing hair.
How Does Oral Finasteride Work?
Male pattern hair loss is primarily driven by genetic sensitivity to DHT.
Elevated DHT levels can:
- Shrink hair follicles
- Shorten the hair growth cycle
- Reduce hair thickness
- Lead to progressive follicle loss
Patients typically use it to:
- Slow ongoing hair shedding
- Preserve existing density
- Improve hair thickness
- Support long-term maintenance
- Complement other treatment modalities
Results are gradual and require consistent use over time.
Types and Forms of Finasteride
Oral Finasteride Tablets
This is the most widely used form of treatment. Taken once daily, it works systemically to reduce DHT levels throughout the body.
Benefits:
- Strong clinical evidence
- Simple daily dosing
- Effective hormonal suppression
It is often used as a foundational medical treatment for male pattern hair loss.
Oral Finasteride Dosage
The appropriate dosage of oral finasteride is determined by the specific condition being addressed and is typically administered with or without food. For those managing hair loss, the standard therapeutic dose is 1 mg once daily, which is widely utilized in clinical practice for effective DHT suppression. Patients generally observe results within a 3–6 month timeline.
In cases of benign prostatic hyperplasia (BPH) or an enlarged prostate, the recommended dosage is 5 mg daily, with symptom relief typically occurring after approximately 6 months of consistent use.
Important Safety Considerations
- For Men Only: This treatment is not indicated for women or children and may cause birth defects in male infants. Women who are pregnant or planning to conceive must strictly avoid handling broken or crushed tablets.
- Warnings & Side Effects: While most tolerate the medication well, a small percentage may experience sexual dysfunction, such as reduced libido or erectile changes, as well as mood-related shifts or breast enlargement. In rare instances, sexual side effects may persist following discontinuation.
- PSA Testing: Finasteride can lower prostate-specific antigen (PSA) levels, a factor that medical professionals must consider during prostate cancer screenings.
For comprehensive guidance on usage, dosing protocols, and safety precautions, it is essential to consult with your physician during a clinical evaluation. So patients should only take finasteride under medical supervision, as consistency and proper dosing are essential for long-term effectiveness. At Clinique de Paris, all prescriptions are based on clinical evaluation and individualized risk assessment.
Who Is a Good Candidate in Taking the Oral Finasteride?
Oral finasteride is typically considered for patients with:
- Receding hairlines
- Crown thinning
- Diffuse thinning
- Early-stage androgenetic alopecia
Not all hair loss is hormonal, and accurate diagnosis is essential before treatment.
How Long Does Treatment Take?
Hair restoration is a gradual process.
General timeline:
- 0–3 months: reduced shedding
- 3–6 months: early signs of thickening
- 6–12 months: visible improvement in density
But the results depend on:
- Genetics
- Severity of hair loss
- Treatment consistency
- Whether combination therapy is used
Stopping treatment may allow hair loss to gradually resume.
Oral vs Topical Finasteride
Oral Finasteride
- Systemic dihydrotestosterone (DHT) reduction throughout your entire bloodstream and body, rather than just locally on your scalp
- Strong clinical evidence
- Once-daily convenience
- May not be suitable for all patients and may cause systemic side effects
Topical Treatment Approach (only by Clinique de Paris)
- Local scalp targeting
- Designed for individualized care
- Often used alongside Minoxidil
- Suitable for combination-based protocols
- Lower systemic exposure compared to oral therapy
- May help reduce the likelihood of systemic side effects in some patients
Clinique de Paris evaluates both oral and topical treatment approaches to determine the most appropriate strategy based on each patient’s hair loss pattern, medical history, and treatment goals.
Clinique de Paris Topical Hair Treatments
At Clinique de Paris, oral medication is only one part of a broader medical strategy.
A significant component of treatment includes topical scalp-based therapies, designed to act directly at the follicular level.
These topical approaches are commonly used for patients who:
- Prefer localized treatment options
- Require combination therapy
- Need additional support alongside oral medication
- Are assessed as better suited for non-systemic approaches
This allows for a more tailored and controlled treatment strategy based on individual diagnosis.
Can Finasteride Be Combined With Other Treatments?
Yes. Combination therapy is a central part of modern hair restoration at Clinique de Paris.
- Finasteride + Minoxidil Therapy. A foundational combination used to reduce DHT activity, stimulate follicle growth, and improve overall hair density. We have these proprietary hair serums available in clinic, a prescription-only topical solutions and assessment with our doctors is required.
- Regenerative Scalp Treatments. Support scalp health and enhance treatment response.
- Direct Hair Implantation (DHI). Used in advanced cases where follicles are no longer active.
Combination Therapy: Finasteride + Minoxidil Approach
A core element of modern hair restoration at Clinique de Paris is the combination of Finasteride and Minoxidil, used in both oral and topical treatment planning depending on patient suitability.
This combination targets hair loss through two complementary mechanisms:
- Finasteride: helps reduce DHT, the hormonal driver of hair follicle miniaturization
- Minoxidil: supports follicle stimulation and improves scalp blood flow
Together, they address both the cause and the growth environment of hair loss.
This dual-pathway strategy is commonly used for:
- Early to moderate androgenetic alopecia
- Patients needing stronger stabilization support
- Individuals combining medical therapy with procedural treatments
When Is a Hair Transplant Necessary?
Medical therapy helps preserve existing hair but cannot restore inactive follicles.
A hair transplant may be recommended for:
- Advanced baldness
- Significant recession
- Long-standing hair loss
At Clinique de Paris, Direct Hair Implantation (DHI) is performed to achieve:
- Natural-looking hairlines
- High-density restoration
- Minimal downtime
- Long-term structural results
Medical and surgical treatments are often combined for optimal outcomes.

Conclusion
Oral finasteride remains a cornerstone treatment for androgenetic alopecia, primarily by reducing DHT and slowing follicular miniaturization.
However, modern hair restoration requires a broader, structured approach.
At Clinique de Paris, treatment strategies often include:
- Oral finasteride when necessary
- Combination Finasteride and Minoxidil topical solutions
- Regenerative and procedural options when needed
The goal is not only to slow hair loss, but to build a personalized, multi-layered treatment plan based on each patient’s condition and long-term hair goals.
In the landscape of modern hair restoration, the standard of care has evolved into a precision-based and medically guided discipline, increasingly defined by individualized combination-driven protocols.
