What Is Finasteride

The FDA has approved Finasteride as a prescription medication for treating male pattern baldness, also known as androgenetic alopecia. Originally, it received FDA approval as Proscar for treating benign prostatic hyperplasia (BPH). It is a type of non-cancerous prostate enlargement. After a few years, it was also approved for hair loss treatment and sold as Propecia. 

Today, both the higher-dose version of Finasteride, use for treating an enlarged prostate. And the lower-dose version for hair loss treatment are available in generic forms under various brand names. According to experts, the medication is in tablet form and is intended for daily use. For treating hair loss, the usual dosage is 1mg per day.

Why Is This Medication Prescribed

Proscar or Finasteride is a medication that doctors prescribe to treat benign prostatic hypertrophy (BPH). Which is the enlargement of the prostate gland. Patients can use it alone or in combination with another medication called Cardura (doxazosin). The medication is effective in treating symptoms of BPH such as frequent and difficult urination. And may also reduce the likelihood of acute urinary retention (a sudden inability to urinate) as well as decreasing the need for prostate surgery. 

The doctor prescribes Finasteride, also known as Propecia, to treat male pattern hair loss in men. This condition causes hair on the scalp to thin gradually. Leading to balding or a receding hairline. Women or children should not use this medication. And it is not effective for treating thinning hair at the temples. 

The class of medications that Finasteride belongs to is called 5-alpha reductase inhibitors. It works by blocking the body’s production of a male hormone. That causes the prostate gland to enlarge in BPH patients. And by blocking the body’s production of a male hormone in the scalp that stops hair growth in men with male pattern hair loss.

Mechanism Of Action Of Finasteride For Hair Loss

Finasteride tablets are a type of 5 alpha-reductase inhibitors (5-ARIs). That work by inhibiting the action of the 5 alpha-reductase enzyme. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT). Which plays a significant role in male pattern baldness. DHT can bind to hair follicle receptors and cause hair miniaturization, leading to hair loss.

By inhibiting the 5 alpha-reductase enzyme, finasteride significantly reduces the amount of DHT in the bloodstream. Protecting the hair follicles from DHT-related damage. Research indicates that finasteride lowers serum DHT levels by over 70 percent.

This can lead to a slowing or complete cessation of hair loss. With many men noticing significant hair regrowth in areas affected by male pattern baldness after starting finasteride treatment.

Clinical trials have demonstrated the effectiveness of finasteride in treating hair loss. In long-term, placebo-controlled clinical trials. 90 percent of men who use finasteride maintained their hair or saw improvements in hair growth. In comparison, 75 percent of men who used a non-therapeutic placebo experienced worsening hair loss.

Studies have also shown that finasteride can increase hair count and density in men with male pattern baldness. In short, finasteride works for most men. Producing improvements in hair growth and density with treatment.

How Effective Is Topical Finasteride

Many different experts have different opinions on the effectiveness of topical Finasteride. Some experts believe that Finasteride has shown to be clinically effective in 90% of men with male pattern baldness. And can help maintain existing native hair, which provides a longer-lasting result. 

It can also slow down the process of hair loss significantly. However, they suggest that it is too early to comment on whether the topical solution is as effective as the tablet form. A study reported that topical Finasteride treatment reduced scalp DHT by 68 to 75%. And oral Finasteride reduced it by 62 to 72% for men with androgenetic alopecia.

On the other hand, Some other experts point out that the stage at which patients are starting treatment is an important factor in determining the effectiveness of topical Finasteride. If the hair loss is long-standing. There may be fewer viable hair follicles from which new hair can grow. 

However, they are optimistic about the benefits of topical Finasteride, saying that it can help to increase hair density and slow further hair loss by reducing the amount of DHT locally at the hair follicle. Topical Finasteride may work equally well as the oral form. But with a reduced chance of side effects. The treatment’s effectiveness may vary from person to person.

For What Types Of Hair Loss Is Finasteride An Effective Treatment

The natural hair growth cycle involves a certain amount of daily shedding. Typically around 50 to 100 hairs, which is not noticeable. However, if you’re experiencing noticeable hair loss. It could be a problem. Although the FDA approves finasteride for male pattern baldness treatment. 

It is essential to note that there are other types of hair loss, such as temporary telogen effluvium, autoimmune alopecia areata, and fungal infection tinea capitis. Stress, infections, surgery, hormonal changes, and fungal infections cause hair loss, not DHT. And hence Finasteride cannot slow down, stop, or reverse their effects.

What is the duration for Finasteride to take effect?

To achieve consistent results with finasteride, it is important to take the medication consistently over the course of several months as it does not work overnight. Although the body starts absorbing finasteride and reducing DHT levels immediately, it takes an average of three to four months before any visible improvements in hair growth can be observed.

Online Companies Are Claiming About Topical Finasteride

The effectiveness of these topical treatments and how they work to treat hair loss is a question that needs to be explored.

How And When Should Finasteride Be Taken?

Topical Vs. Oral Finasteride

People often use Finasteride in tablet form to treat male pattern baldness. If someone experiences side effects while using the drug, they can opt for a popular alternative, which is using it topically. 

Topical finasteride provides localized treatment for hair loss and is a safe and effective option. It is used on the scalp and can be used in combination with the oral drug.

According to studies, using 0.25% topical finasteride is equivalent to using 1 mg of the tablet. It’s worth noting that, unlike oral Finasteride, topical Finasteride is not an FDA-approved treatment for hair loss.

Experts explain that they traditionally administered Finasteride orally, but they now also use it topically in liquid form, applying it directly to the scalp. They believe that products like these are more accessible for hair loss patients who do not prefer oral medication. Men who want to avoid some of the side effects associated with the tablet form may find topical formulations of finasteride to be a good option. 

While some other experts point out that oral Finasteride can cause side effects, such as erectile dysfunction in a small percentage of patients. Finasteride counteracts the effects of DHT, which is a broken-down form of testosterone that plays a major role in hair loss. Too much DHT can cause hair follicles to shrink and ultimately fall out. Finasteride can stimulate regrowth in areas of thinning. Additionally, Minoxidil, which is a medically-approved topical treatment for male pattern hair loss, may improve the effectiveness of Finasteride by allowing it to penetrate more deeply.

Minoxidil Vs Finasteride

Both Propecia and Rogaine are oral medications commonly used to treat hair loss.

Finasteride is a popular medication for treating male pattern baldness as it not only stops hair loss but also promotes the regrowth of new hair. It is an FDA-approved drug that provides a safe and painless solution for treating hair loss. Finasteride works best for males above 30 years old, but it is not recommended for females. With a higher success rate, Finasteride is an effective option for treating hair loss.

On the other hand, Minoxidil is a more effective option for treating early alopecia and promoting hair regrowth. However, it is not effective for every case of male pattern baldness. Compared to Finasteride, many people report no change in hair loss after taking Minoxidil, and it has a lower success rate. Nevertheless, Minoxidil has fewer side effects and can be used in females as well.

What Information Should I Be Aware Of Regarding The Storage And Disposal Of This Finasteride?

Keep the medication in its original container, tightly closed, and out of children’s reach. Keep the medication at room temperature and away from excessive moisture and heat. Do not store it in the bathroom.

It is crucial that you attend all appointments as scheduled and inform the laboratory personnel and your doctor about the medication you are taking before any laboratory tests.

Maintain a written record of all prescription and nonprescription medications, vitamins, minerals, and dietary supplements you are taking. It is necessary to carry this list with you when you visit a doctor or are admitted to a hospital. In case of emergencies, it will be useful.
