 Introduction
Finasteride is a prescription medication commonly used to treat hair loss in men, particularly male pattern baldness (androgenetic alopecia). It works by addressing the hormonal causes of hair loss, helping to promote hair growth and prevent further hair loss.
Mechanism of Action
Finasteride works by inhibiting the enzyme 5-alpha-reductase. This enzyme is responsible for converting testosterone into
dihydrotestosterone (DHT), a hormone that can shrink hair follicles and lead to hair loss in genetically predisposed individuals. By reducing the levels of DHT, finasteride helps to prevent further hair loss and promote hair regrowth.
Effectiveness
Clinical studies have shown that finasteride is effective in promoting
hair growth and preventing further hair loss in a significant proportion of
men with male pattern baldness. Key findings include:
- Improvement in hair growth in 48% of men after one year and 66% after two years.
- 83% of men experienced no further hair loss after two years of treatment.
- Most men notice a reduction in hair shedding and a noticeable improvement in hair growth after around one year of consistent use.
Usage and Dosage
Finasteride is typically taken as a 1 mg tablet once daily. It is
important to take the medication consistently to maintain its effects.
Missing doses or discontinuing the medication can lead to a reversal of its
benefits.
Finasteride Side Effects
While finasteride is generally well-tolerated, some men may experience
side effects. Common side effects include:
- Decreased libido
- Ejaculation disorders
- Erectile dysfunction
These side effects are usually reversible upon discontinuation of the medication.
In rare cases, finasteride may cause mood changes such as depression. It is important to consult with a healthcare provider if any side effects occur.
Considerations
Finasteride is not recommended for use in women, especially those who are pregnant or may become pregnant, due to the risk of birth defects in male fetuses. It is also important to inform your healthcare provider if you are undergoing PSA testing for prostate cancer, as finasteride
can affect the result.
Purchasing Finasteride Online (Also branded as Propecia)
Although a doctor needs to prescribe this medication, it can be obtained
through a consultation with an online pharmacy that will provide a clinical
review. You can then purchase from that pharmacy. The process usually
completes within 24 hours. You can then purchase Finasteride and later
obtain repeat prescriptions. It can be purchased branded as Propecia or
unbranded as finasteride, with the branded medication tending to be more
expensive.
Natural Alternatives
Saw
Palmetto is a natural supplement with a mechanism of action that is similar to that of finasteride
and is available without prescription in various forms, including
oral
supplements and
topical treatments but has been shown to be less effective in clinical studies.
Conclusion
Finasteride is a proven and effective treatment for
male pattern baldness, helping to reduce hair loss and promote hair regrowth. As with any medication
such as finisteride and
dutasteride, it is important to consult with a healthcare provider to determine if finasteride
is the right treatment for you.
