What is androgenetic alopecia?
Androgenetic alopecia, also known as pattern hair loss, is a common type of hair loss that affects both men and women. It's characterised by a distinct pattern of hair thinning, primarily caused by a genetic predisposition and the impact of androgens (hormones like testosterone and its byproduct, DHT) on hair follicles.
This condition often manifests differently between genders. In men, it generally begins with a receding hairline and hair loss at the crown of the head.
For women, it typically presents as a diffuse thinning of hair across the entire scalp, maintaining the frontal hairline.
The mechanism of androgenetic alopecia is deeply rooted in genetics and hormones. Hair follicles affected by this condition are genetically sensitive to dihydrotestosterone (DHT), a byproduct of testosterone.
This sensitivity leads to miniaturisation, where hair follicles shrink over time, producing thinner, shorter, and less pigmented hair until they eventually stop producing hair altogether.
Although the condition is more prevalent and often more severe in men, women can also experience it, especially post-menopause, when estrogen levels drop and fail to counterbalance the effects of DHT.
Understanding androgenetic alopecia is the first step towards seeking appropriate and effective treatment.
What is spironolactone?
Spironolactone is primarily used as a diuretic, or "water pill," to treat high blood pressure and fluid retention. However, it also has anti-androgen effects, meaning it can block the action of male sex hormones, which makes it helpful in treating a range of conditions, including hair loss in women.
In more detail, spironolactone belongs to a class of drugs known as potassium-sparing diuretics.
It works by helping the kidneys eliminate sodium and water from the body while minimising potassium loss.
Due to its anti-androgen properties, it can also be used off-label for treating conditions like hirsutism (unwanted hair growth), acne, and female pattern hair loss, all of which can be exacerbated by excess androgen hormones.
Spironolactone can slow hair thinning and promote hair growth in women suffering from androgenetic alopecia by blocking androgen receptors and decreasing androgen production.
However, it's typically not recommended for men due to its hormonal effects.
How does spironolactone work?
Spironolactone works by blocking the action of androgen hormones in the body. It does this by binding to androgen receptors and preventing these hormones from attaching, reducing their overall effects. In the context of hair loss, this anti-androgen action helps slow the process of hair thinning and can promote hair growth.
How effective is spironolactone?
Spironolactone's effectiveness can vary depending on the condition it's used to treat. In the context of female pattern hair loss, it has shown promising results in slowing down hair thinning and promoting growth.
However, the evidence must be mixed, and more high-quality, large-scale studies are required to establish its efficacy definitively.
Individual responses can vary with any medication, and discussing treatment options with a healthcare provider is essential.
What is finasteride?
Finasteride is a prescription medication primarily used to treat male pattern baldness and benign prostatic hyperplasia (BPH). It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone that can contribute to hair loss and prostate growth.
Further, finasteride's mechanism of action makes it a valuable tool in managing conditions sensitive to DHT. In the case of hair loss, DHT can shrink hair follicles, leading to thinner, shorter hairs and, eventually, hair loss.
Finasteride can slow down or even reverse this process in some individuals by inhibiting the conversion of testosterone to DHT.
While it's typically prescribed for men due to its potential side effects in women, it has been used off-label in post-menopausal women or those not planning to conceive.
However, women of childbearing age should not use finasteride due to the risk of birth defects.
How does finasteride work?
Finasteride works by inhibiting the enzyme 5-alpha reductase, which is responsible for converting testosterone into its more potent form, dihydrotestosterone (DHT). By reducing DHT levels, finasteride can help slow down or even reverse the process of hair miniaturisation and hair loss caused by androgenetic alopecia.
How effective is finasteride?
Finasteride is generally considered effective in treating male pattern hair loss, with many clinical trials showing it can slow the progression of hair loss and even improve hair growth in some men. However, its effectiveness in women must be clarified, with more mixed results reported and fewer high-quality studies available.
Individual responses can vary with any medication, so discussing treatment options and potential side effects with a healthcare provider is crucial.
What are the side effects of spironolactone and finasteride?
While both Spironolactone and Finasteride have been celebrated for their role in combating hair loss, it's equally crucial to understand their potential side effects.
Side effects of spironolactone:
- Increased urination, potentially leading to dehydration if fluid intake isn't properly managed.
- Dizziness
- Nausea
- Headaches
- Menstrual irregularities (more severe but less common)
- Breast tenderness (more severe but less common)
- Postural hypotension: a drop in blood pressure upon standing (more severe but less common)
- Possible impact on potassium levels, with a risk of hyperkalemia, which is characterised by high potassium levels in the blood (regular monitoring is necessary)
Side effects of finasteride:
- Decreased libido
- Erectile dysfunction
- Ejaculation disorder
- Mood changes, including instances of depression
- Risk of a specific type of birth defect, meaning women who are pregnant, or might become pregnant, should not handle finasteride.

Spironolactone vs finasteride: What are the differences?
While both are used in the battle against hair loss, spironolactone and finasteride function differently and have unique advantages and side effects. These fundamental differences lie in their mechanisms of action, typical usage, effectiveness, and side effects.
Mechanism of action
Spironolactone operates as an anti-androgen, blocking androgen receptors and reducing androgen production, which can slow hair thinning and promote hair growth in women.
In contrast, finasteride inhibits the enzyme 5-alpha reductase, which converts testosterone into DHT, a hormone that can contribute to hair loss and prostate growth.
Typical usage
Spironolactone is primarily used as a diuretic for treating high blood pressure and fluid retention but also sees off-label use for conditions like female pattern hair loss and acne.
On the other hand, finasteride is mainly used to treat male pattern hair loss and benign prostatic hyperplasia (BPH).
Effectiveness
Spironolactone has shown promise in treating female pattern hair loss, although the evidence is mixed, and more large-scale studies are needed.
Finasteride, however, is generally considered effective in treating male pattern hair loss, with fewer high-quality studies available on its effectiveness in women.
Spironolactone vs finasteride: Which one is right for you?
Spironolactone is often used in women with pattern hair loss, while finasteride is typically used in men due to the potential risks to pregnant women.
