Most women experience hair loss at some point in their lives. Hair loss and hair thinning is prevalent in post-menopausal women due to various underlying reasons. However, this can be treated with spironolactone. This FDA-approved anti-androgen drug can help prevent hair loss (1).
Spironolactone was mainly used to treat hypertension and fluid retention. However, it was found to reduce adrenal androgen production and minimize female pattern hair loss or androgenetic alopecia (1). In this article, we have explored how spironolactone works and how you can use it to prevent hair loss. Scroll down for more information.

What Is Spironolactone?
Spironolactone is an anti-androgen drug. It was mainly used for treating hypertension, symptoms of polycystic ovary syndrome (PCOS) and hirsutism. However, spironolactone prevents adrenal androgen production in the body and thus, minimizes PCOS hair loss or androgenetic alopecia (1). Besides treating female pattern hair loss (FPHL), it may also be beneficial in reducing hirsutism and acne. The section below delves further into how it works to prevent hair loss.
How Does Spironolactone Work?
Spironolactone slows down androgen production. Androgens are a group of male sex hormones, including testosterone. In females with PCOS, excess production of androgens may cause hair loss. A study found that the daily consumption of spironolactone in the prescribed dosage can reduce hair loss and increase the number of hair follicles in the anagen phase (1).
The dosage of spironolactone depends on the purpose it is being used for.
How Much Of Spironolactone Is Prescribed For Hair Loss?
A study found that a dose of 200 mg of oral spironolactone effectively improved female pattern hair loss (1). Doctors generally prescribe a dosage between 50-200mg of spironolactone for hair loss. However, the dosage may vary, depending on the severity of your hair loss. The doctor may even prescribe a combination of drugs to be taken with spironolactone, such as (1):
- Spironolactone With Oral Contraceptive: This combination is often used to prevent menstrual irregularities and improve female pattern hair loss and acne.
- Spironolactone With Minoxidil: A 2% topical minoxidil solution improves hair growth rate and hair thickness by lengthening the anagen (growth) phase and shortening the telogen (hair fall) phase of the hair (2).
Your doctor may also prescribe topical spironolactone for treating hair loss.
Spironolactone: Topical Or Oral?
You may take spironolactone orally or apply a topical solution.
Topical treatment is preferred as it cuts down many possible side effects of oral spironolactone. Research found that 5% spironolactone gel can promote hair growth and is a good option for managing androgenic alopecia (3).
The doctor will evaluate the severity of your hair loss and other complications caused by PCOS and then prescribe either topical or oral spironolactone. Once you start taking it, you may expect results in a few months. However, the duration may vary from person to person.
How Long Does It Take For Spironolactone To Work?
Do not expect overnight results. Spironolactone may take at least six months to show results. However, it may vary, depending on the severity of the condition. You may even notice changes after a year of using the drug.
You have to follow up with your doctor after taking spironolactone for six months. They may even increase the dosage, depending on the results, or suggest a combination of medications.
Spironolactone is not prescribed for everyone. Find out next who can use the drug and who should avoid it.

Teenagers below 18 years of age should also avoid this drug. If taken in the wrong way, spironolactone may have some health risks.

- Dry skin
