Finasteride Singapore: Hair Loss Medication

Hair loss, a common issue impacting both men and women, can affect not only appearance but also self-esteem. If you are experiencing male pattern baldness and you are on the hunt for an effective solution, Finasteride might be the answer you're seeking.

Available in both topical and oral forms, this medication has proven beneficial for many. 

1) What is the difference between Oral and Topical Finasteride?

Finasteride is a prescription medication in Singapore primarily used to treat male pattern baldness (androgenetic alopecia) and enlarged prostate (benign prostatic hyperplasia). 

It falls under the category of drugs known as 5-alpha reductase inhibitors. Finasteride comes in two forms: a tablet form for oral intake and a topical solution applied directly to the scalp.

Both forms of the drug work by reducing levels of dihydrotestosterone (DHT), a hormone that contributes to hair loss, but their methods of application and systemic effects can vary.

Oral Finasteride

Oral Finasteride, typically available as a tablet, is taken once daily. The drug is systemic, meaning that it affects the whole body. The systemic nature of oral Finasteride can be both a benefit and a drawback. 

On the one hand, the overall reduction in DHT levels can be effective in slowing hair loss and promoting hair growth. On the other hand, because it affects the entire body, it can lead to side effects such as sexual dysfunction or mood changes in a small percentage of users.

Topical Finasteride

Topical Finasteride, often in the form of a hair spray, is applied directly to the scalp. This direct application allows the medication to target the area where it's needed most. It reduces DHT levels in the scalp without significantly affecting DHT levels in the rest of the body.

The primary advantage of topical Finasteride is that it's less likely to cause systemic side effects compared to the oral form, as less of the drug is absorbed into the body. However, the effectiveness of topical Finasteride in promoting hair growth may vary between individuals, and it can be less convenient to apply daily.

2) What are the benefits of Finasteride in Singapore?

Finasteride offers several benefits, particularly for those grappling with hair loss. Here are some key advantages:

  • Hair Regrowth: Finasteride has proven effective in promoting hair regrowth by slowing down hair loss and improving hair thickness.
  • Prostate Health: Besides hair growth, it's beneficial for men with an enlarged prostate, reducing its size and associated symptoms.
  • Convenience: The drug is easily incorporated into daily routines, either as an oral tablet or a topical solution.

3) How does Finasteride work?

Finasteride works by targeting a specific hormonal process in the body. To fully understand its mechanism of action, we need to delve into the basics of human hair growth and the role of hormones in this process.

Human hair growth occurs in cycles, each consisting of a growth phase (anagen), a regression phase (catagen), and a rest phase (telogen). Dihydrotestosterone (DHT), a derivative of the male hormone testosterone, plays a significant role in hair growth and hair loss.

In some individuals, particularly those with androgenetic alopecia or male pattern baldness, hair follicles are genetically sensitive to DHT. Over time, DHT causes these sensitive hair follicles to miniaturize, shortening the anagen (growth) phase. This leads to thinner, shorter hairs and eventually hair loss when the follicle no longer produces hair.

This is where Finasteride comes in. Finasteride is a type of medication known as a 5-alpha-reductase inhibitor. The 5-alpha-reductase enzyme is responsible for converting testosterone into DHT. By inhibiting this enzyme, Finasteride reduces the amount of DHT in the scalp and the body overall.

By lowering DHT levels, Finasteride helps to halt the miniaturization of the hair follicles, slowing down or even stopping hair loss. In some cases, it can also stimulate the hair follicles to revert to a normal growth cycle, leading to hair regrowth.

It's important to note that Finasteride does not eliminate DHT completely, as this hormone also plays other roles in the body. Instead, it lowers DHT levels to a point where it is less likely to cause hair loss, while still allowing the body to function normally.

Remember, Finasteride is a long-term treatment. It needs to be used consistently over time to maintain its benefits. If the medication is discontinued, DHT levels will rise again, potentially leading to a return of hair loss. 

4) How long must you take Finasteride for?

The effectiveness of Finasteride isn't immediate. It usually takes about three to four months of daily use before any noticeable improvement is seen. 

Consistent use is key - discontinuing the medication may lead to a reversal of progress within twelve months.

5) What are the common side effects of Finasteride in Singapore?

Finasteride, like any medication, does have potential side effects. However, it's important to remember that not everyone experiences these, and for many people, the benefits of the treatment significantly outweigh the risks.

  1. Sexual Side Effects: A small percentage of men taking Finasteride may experience sexual side effects such as a decreased sex drive, difficulty with erections, or a reduction in the volume of ejaculate. These side effects are typically mild and often resolve over time, even with continued use of the medication. Additionally, it's worth noting that these side effects are not permanent and usually revert back to normal once the medication is stopped.
  2. Allergic Reactions: Though rare, some individuals may have an allergic reaction to Finasteride. Symptoms could include rash, itching, swelling, severe dizziness, or trouble breathing. If you notice any of these symptoms, it's essential to seek medical attention immediately. However, keep in mind that allergic reactions are extremely rare, and most people tolerate Finasteride very well.
  3. Breast Changes: In some cases, men taking Finasteride have reported changes in breast tissue such as lumps, pain, or nipple discharge. While these side effects are also rare, it's important to contact your healthcare provider if you notice any changes.

While these potential side effects might seem concerning, it's vital to remember that Finasteride has been extensively studied and is widely used, with a large majority of users experiencing significant benefits with minimal or no side effects. 

It's also important to consider the impact of hair loss on self-esteem and quality of life. For many, the potential for hair regrowth and the slowing of hair loss far outweigh the small risk of side effects.

Always consult your doctor for professional advice before starting a new medication.

6) When can results be seen?

As with most hair loss treatments, patience is key. Most users start noticing results from Finasteride after three to four months of consistent use. However, for more significant improvements, it may take up to a year.

7) What other types of hair loss medications are there in Singapore?

Beyond Finasteride, other common hair loss treatments include:

  • Minoxidil: It's used to stimulate hair growth in both men and women.
  • Regenera Activa: Treatment for hair loss that uses your own healthy hair cells to stimulate hair growth. 
  • Hair transplant: A surgical procedure that moves hair from a dense area to a balding area.

8) Can Finasteride be combined with Minoxidil?

Combining Finasteride and Minoxidil for the treatment of hair loss can offer several advantages, as these two medications work in different but complementary ways to combat hair loss and stimulate hair regrowth. 

One popular method is for guys to use topical finasteride combined with topical minoxidil, taken together with oral minoxidil. This reduces the risk of systemic side effects from oral finasteride.

Here are some of the key benefits of this combination therapy:

1. Comprehensive Approach: Finasteride and Minoxidil target different aspects of the hair loss process, offering a more comprehensive approach to treatment. Finasteride works by reducing levels of dihydrotestosterone (DHT), a hormone that contributes to hair loss, while Minoxidil improves blood flow to hair follicles, providing them with more nutrients and oxygen.

2. Enhanced Effectiveness: While both Finasteride and Minoxidil can be effective when used alone, combining them can potentially enhance overall effectiveness. Some studies suggest that using both medications together can result in greater hair regrowth and slowing of hair loss than using either medication individually.

3. Potential for Synergistic Effect: Because Finasteride and Minoxidil work in different ways, they could potentially have a synergistic effect when used together. This means that the combined effect of the two medications could be greater than the sum of their individual effects.

4. Flexibility of Treatment: Having both an oral (or topical) and a topical medication in your treatment regimen provides flexibility. Depending on the severity of hair loss and your lifestyle, your healthcare provider can help you determine the best way to use these medications together.

5. Improved Patient Satisfaction: Many patients report higher satisfaction rates with combination therapy. This could be due to the improved results seen with the combination of Finasteride and Minoxidil, compared to using each drug alone.
