About Finasteride
Finasteride is used for the treatment of benign prostatic hyperplasia (BPH) caused by an enlarged prostate and male pattern hair loss (androgenetic alopecia).
Finasteride is a 5-alpha reductase inhibitor, an enzyme involved in the conversion of testosterone to dihydrotestosterone (DHT), which can cause hair follicles to shrink and stop producing hair.
NowPatient offers Propecia or Finasteride tablets as a treatment for hair loss only, following an online consultation with a prescribing clinician.

Answers to Popular Questions About Finasteride
What is Finasteride?
Finasteride is a 5-alpha reductase inhibitor available in two doses: 1 mg (for male pattern hair loss/androgenetic alopecia) and 5 mg (for benign prostatic hyperplasia/enlarged prostate). For hair loss, finasteride 1 mg is taken daily and works by reducing levels of dihydrotestosterone (DHT), the hormone primarily responsible for hair follicle miniaturisation and male pattern baldness. Propecia is the original brand name for finasteride 1 mg.
How does Finasteride work for hair loss?
Finasteride inhibits the type II 5-alpha reductase enzyme, which converts testosterone to dihydrotestosterone (DHT). DHT causes hair follicle miniaturisation on the scalp in genetically susceptible men, leading to thinner, shorter hair and eventually complete follicle dormancy. By reducing serum and scalp DHT levels by approximately 70%, finasteride slows hair loss, stops progression in most men, and can promote regrowth in many — particularly at the crown and midscalp.
How effective is Finasteride for hair loss?
Clinical studies show that finasteride 1 mg daily halts hair loss in approximately 80–90% of men and produces visible regrowth in about 65% after 2 years. Results are best at the crown and midscalp. The hairline may improve modestly. Hair regrowth typically becomes noticeable after 3–6 months, with maximum benefit seen at 1–2 years. If treatment is stopped, hair loss resumes within 6–12 months.
How do I take Finasteride for hair loss?
Take one 1 mg tablet daily at the same time each day. It can be taken with or without food. Results take time — most men see visible improvement after 3–6 months, with maximum results at 1–2 years. Treatment is long-term; if you stop taking finasteride, hair loss will resume. It is often used alongside topical minoxidil for enhanced results.
What are the side effects of Finasteride?
The most discussed side effects are sexual: decreased libido, erectile dysfunction, and reduced ejaculate volume, which affect approximately 1–2% of men in clinical trials. These side effects are usually mild and reversible upon stopping treatment. In most men who continue treatment, side effects resolve spontaneously. Breast tenderness or enlargement (gynaecomastia) is rare. Some men report mood changes. Finasteride reduces PSA levels by approximately 50%, which should be noted for prostate cancer screening.
What is post-finasteride syndrome?
Post-finasteride syndrome (PFS) is a controversial and unproven condition in which men report persistent sexual, neurological, and psychological side effects after stopping finasteride. While some men have reported such symptoms, large clinical studies and pharmacological data have not established a causal link. The MHRA lists sexual side effects as uncommon and generally reversible. Discuss any concerns with your prescriber before starting treatment.
Can women take Finasteride?
Finasteride 1 mg is licensed for men only. Women of childbearing age must NOT handle crushed or broken finasteride tablets, as the drug can be absorbed through the skin and may cause abnormalities in male foetal genitalia. Finasteride is very occasionally used off-label for female pattern hair loss in postmenopausal women under specialist supervision, but this is not standard practice.
How can I get Finasteride?
Finasteride 1 mg for hair loss requires a prescription and is available from your GP or through NowPatient. It is not available on the NHS for hair loss (it is a cosmetic indication). NowPatient offers online consultations and home delivery of finasteride at competitive prices.
