Finasteride is a medication widely used for the treatment of male pattern hair loss, also known as androgenetic alopecia. It is an FDA-approved oral medication that has shown significant efficacy in combating hair loss. In this article, we will explore the effectiveness of finasteride from various aspects and provide you with valuable insights on this widely used hair loss treatment.
1. Mechanism of Action
Finasteride works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is the hormone responsible for shrinking hair follicles in individuals with androgenetic alopecia. By reducing DHT levels, finasteride helps to prevent further hair loss and promote hair regrowth.
It is important to note that finasteride primarily works for the crown and middle of the scalp, rather than the front or receding hairline areas. It is less effective in treating hair loss in women due to hormonal differences.
2. Effectiveness
Studies have shown that finasteride is effective in preventing further hair loss and promoting hair regrowth in males with androgenetic alopecia. A clinical trial conducted over a period of two years demonstrated that approximately 83% of men maintained or increased their hair count while using finasteride.
It is worth noting that the effectiveness of finasteride may vary from person to person. Some individuals may experience significant hair regrowth, while others may observe a slower response. It is recommended to continue treatment for at least six months to assess its effectiveness.
3. Dosage and Administration
Finasteride is available in the form of oral tablets to be taken once daily. The recommended dosage is 1mg per day. It is important to follow the prescribed dosage and consult a healthcare professional before starting or discontinuing the treatment.
It is essential to note that discontinuing the use of finasteride may result in a reversal of the effects, leading to hair loss within 12 months.
4. Side Effects
While finasteride is generally well-tolerated, it may cause some side effects in a small percentage of users. The most common side effects include decreased libido, erectile dysfunction, and reduced ejaculate volume. These side effects are usually mild and resolve upon discontinuing the medication.
It is crucial to consult a healthcare professional if you experience any persistent or bothersome side effects while using finasteride.
5. Combination Therapy
Some individuals opt for combination therapy to enhance the effectiveness of finasteride. Combining finasteride with minoxidil, a topical hair growth solution, may yield better results. Minoxidil helps to stimulate hair growth and can be used in conjunction with finasteride for a comprehensive approach to hair loss treatment.
6. Average Price and Price Range
The average price of finasteride varies depending on the brand and quantity of tablets. On average, a month's supply of finasteride 1mg tablets can cost between $30 to $80. Generic versions of finasteride are also available at a lower cost.
It is important to consult with your healthcare provider or pharmacist for the most accurate and up-to-date pricing information.
7. Precautions and Considerations
Pregnant women or women planning to become pregnant should avoid handling finasteride tablets as it can be absorbed through the skin and may cause harm to the developing fetus.
Additionally, individuals with liver disease, prostate cancer, or a history of allergic reactions to finasteride should exercise caution and consult their healthcare provider before initiating treatment.
