Does Finasteride Stop Hair Loss or Support Regrowth? Evidence Explained By Clinicians

If you are noticing a receding hairline, thinning at the crown, or more shedding than usual, it is natural to start looking for solutions that genuinely work. One of the most common questions we hear through our online consultations is: does finasteride work, and can it actually stop hair loss or help bring hair back?

At The Care Pharmacy, we support men who want clear, evidence-based guidance and clinically appropriate treatment options. In this article, we will explain what finasteride is, how it works, what results you can realistically expect, and how to decide whether it is right for you.

What Is Finasteride?

Finasteride is a prescription-only medicine used to treat male pattern baldness, also known as androgenetic alopecia. It is typically taken as a daily tablet and works by reducing levels of a hormone linked to hair thinning.

Male pattern hair loss usually follows a recognisable pattern, such as:

  • Thinning at the crown (vertex)
  • Receding hairline at the temples
  • Gradual overall thinning on the top of the scalp

Finasteride is not designed for sudden hair loss, patchy hair loss, or hair shedding caused by illness, nutritional deficiencies, or stress-related conditions. This is why a proper clinical assessment is important before starting.

Does Finasteride Work? The Short Answer

Yes, for many men, finasteride is effective at slowing down hair loss, and in some cases, supporting regrowth.

When people ask, does finasteride work, they often mean one of two things:

  1. Will it stop my hair loss from getting worse?
  2. Will it help me regrow hair that I have already lost?

Clinically, finasteride is best known for helping to stabilise hair loss and protect existing hair. Regrowth is possible, but results vary depending on how early treatment starts and how advanced hair loss is.

How Finasteride Works In The Body

To understand why finasteride can be effective, it helps to know what drives male pattern baldness.

A hormone called DHT (dihydrotestosterone) plays a key role in androgenetic alopecia. In men who are genetically predisposed, DHT causes hair follicles to gradually shrink over time. This process leads to:

  • Shorter hair growth cycles
  • Thinner, weaker hairs
  • Reduced hair density
  • Eventually, follicles that stop producing visible hair

Finasteride works by inhibiting an enzyme called 5-alpha reductase (type II), which converts testosterone into DHT. By reducing DHT levels, finasteride helps slow the follicle miniaturisation process and gives hair a better chance to remain in its normal growth cycle.

What Does The Evidence Say?

Finasteride has been studied extensively for male pattern baldness, or male androgenetic alopecia. Many trials show that it can increase hair count and improve the appearance of hair density over time, particularly in the crown area.

If you are still wondering, if finasteride will work for your specific hair loss pattern, we can help you understand what is most likely based on your history and goals.

How Long Does Finasteride Take To Work?

Finasteride is not a quick fix, and it requires consistency. Most men need several months before noticing meaningful changes.

A realistic timeline looks like this:

  1. Months 1 to 3
    You may not see much difference yet. Some men notice reduced shedding, but it is not guaranteed.
  2. Months 3 to 6
    Early improvements may become noticeable, such as less hair fall or slightly thicker hair in thinning areas.
  3. Months 6 to 12
    This is often when the most visible benefits appear, including improved density or mild regrowth in certain areas.
  4. Beyond 12 months
    Ongoing use helps maintain results. If you stop treatment, hair loss usually resumes over time.

Will Finasteride Regrow Hair Or Just Maintain It?

This depends on the individual, but here is what clinicians commonly see:

  • Most men experience reduced hair loss and better retention of existing hair
  • Many men see some thickening of miniaturised hairs
  • Some men see visible regrowth, especially if treatment begins early
  • Results are usually stronger at the crown than at the hairline

If your hair loss has been progressing for many years, finasteride may still help slow it down, but regrowth may be limited. That does not mean it is not worth considering, especially if preserving what you have is a priority.

Common Questions Men Ask Before Starting

Here are a few practical questions that often come up during consultations:


Yes, daily use is recommended for best results.


In many cases, yes. Combination approaches are common, but suitability should be checked.


Hair loss usually returns gradually, often within months.


No. Finasteride is generally prescribed for adult men and requires clinical screening.


Is Finasteride Worth Trying?

So, does finasteride work?

For many men, the evidence and clinical experience suggest it can be a highly effective option for slowing male pattern hair loss and supporting thicker-looking hair over time. The key is starting early, taking it consistently, and giving it enough time to work.
