Male pattern hair loss — medically known as androgenetic alopecia — is the most common form of hair loss in men, accounting for around 95% of cases. It follows a characteristic pattern: the hairline recedes at the temples while the crown simultaneously thins. Over time, these areas may merge, leaving a horseshoe of hair around the back and sides of the head.
The underlying cause is a genetic sensitivity to dihydrotestosterone (DHT), a hormone derived from testosterone. In susceptible men, DHT binds to androgen receptors in scalp follicles and gradually miniaturises them — each hair cycle producing a thinner, shorter strand until the follicle eventually becomes dormant.

What Is Finasteride?
Finasteride is a prescription-only oral medication and the leading treatment for male pattern baldness in the UK and worldwide. Sold under the brand name Propecia, the 1mg daily tablet works by inhibiting the enzyme (5-alpha reductase type II) responsible for converting testosterone into DHT — reducing scalp DHT levels by up to 70% and halting the follicle miniaturisation process.
It has MHRA approval in the UK and FDA approval in the US specifically for the treatment of androgenetic alopecia in men. It has been in clinical use for over 25 years, giving it one of the most comprehensive long-term safety profiles of any hair loss treatment.

The Clinical Evidence: Does Finasteride Work for Male Pattern Hair Loss?
The short answer is yes — and the evidence is robust. Pivotal clinical trials published in the Journal of the American Academy of Dermatology followed men with male pattern hair loss for five years:
- ~65% of finasteride users experienced visible hair regrowth — not just a slowing of loss
- Hair counts were significantly higher than baseline after 2 years in the treatment group
- The placebo group showed a continued decrease in hair count over the same period
- Results were most pronounced at the vertex (crown) but also meaningful at the frontal hairline
- The benefit was sustained for as long as treatment was continued
Key principle: Finasteride is most effective when started early. Once follicles have been dormant for an extended period, they are unlikely to respond to treatment. The earlier you start, the more hair you can preserve — and potentially regrow.
How to Take Finasteride
Finasteride 1mg is taken orally once daily, with or without food. Consistency is essential — taking it at the same time each day helps maintain steady DHT suppression. If you miss a dose, take it as soon as you remember the same day; do not double up the following day.
It must be taken continuously. If you stop treatment, the DHT-blocking effect ends and hair loss typically resumes within 6–12 months.
Temporary initial shedding is normal. In the first 1–3 months of treatment, some men notice increased shedding as the hair cycle resets. This is a known effect and not a sign that finasteride is failing. It typically resolves and is followed by the stabilisation and improvement phase.
Finasteride Combined with Minoxidil
Finasteride and minoxidil (Regaine) work via entirely different mechanisms and are highly complementary:
| Finasteride | Minoxidil | |
|---|---|---|
| How it works | Reduces DHT systemically — removes the hormonal cause | Stimulates follicles topically — improves blood flow and follicle activity |
| Form | Daily oral tablet (1mg) | Liquid or foam applied to scalp twice daily |
| Prescription needed? | Yes | No — over the counter |
| Efficacy alone | High — 85% improvement over 5 years | Moderate |
| Efficacy combined | Significantly better than either treatment alone | |
Used together, finasteride and minoxidil represent the most effective non-surgical approach to male pattern baldness currently available. See our full comparison guide: Male Balding: Your Complete Treatment Guide.
Side Effects & Safety
Finasteride 1mg has a well-established safety profile built over 25+ years of clinical use. The most discussed potential side effects are sexual in nature:
- Decreased libido — reported in approximately 1–2% of users at the 1mg dose
- Erectile dysfunction — similarly rare at this dose
- Reduced ejaculate volume — uncommon
When these effects occur, they typically resolve on discontinuing treatment or over time. The 1mg dose is considerably lower than the 5mg dose used for prostate enlargement, which further reduces risk.
Not for women: Finasteride must not be taken or even handled by women, particularly those who are pregnant or may become pregnant, due to the risk of foetal abnormality. Always store securely out of reach of women and children.

Finasteride is the most clinically effective oral treatment and is widely considered the first-line prescription option. It has an 85% improvement rate over 5 years in clinical trials and is MHRA and FDA approved for this specific use.
Can finasteride regrow lost hair?
Yes — around 65% of men in clinical trials experienced visible regrowth. Finasteride is most effective when started before significant follicle miniaturisation has occurred. Follicles that have been dormant for a long time are unlikely to respond, which is why early treatment matters.

Can I combine finasteride with minoxidil?
Yes — combining finasteride and minoxidil is considered the most effective non-surgical approach to male pattern baldness. They work through different mechanisms and their effects are complementary. Many men use both together for optimal results.
Is finasteride safe to take long-term?
Yes — finasteride has been in clinical use for over 25 years and has a well-established long-term safety profile at the 1mg hair loss dose. It is MHRA and FDA approved, and millions of men use it continuously without issues.
