Is Finasteride Suitable for Women With Hair Loss?
As a doctor at My Hair UK, I frequently encounter questions regarding hair loss treatments, particularly concerning the use of finasteride among women. Finasteride has long been recognized as a popular and effective treatment for androgenetic alopecia (AGA) in men, but its application in women has been met with a mix of interest and caution. In this article, we will explore the suitability of both oral and topical finasteride for women experiencing hair loss, delve into the potential side effects, and discuss circumstances under which finasteride should not be taken.
Understanding Finasteride
Finasteride is a 5-alpha reductase inhibitor that works by blocking the conversion of testosterone to dihydrotestosterone (DHT), the hormone primarily responsible for hair loss in both men and women. Women do produce testosterone, just in smaller amounts than men and it will affect hair follices in a similar manner if the patient is particularly sensitive regardless of gender, leading to Androgenetic Alopecia (AGA). In women, AGA manifests differently, often resulting in diffuse thinning across the scalp rather than the receding hairlines commonly seen in male pattern baldness. Men have been prescribed Finasteride in pill form as a hair loss treatment for over 20 years now, but it is yet to be licensed for treating women due to side effects.
Recent advances have seen that Finasteride has now been made available in a topical form like a spray, rather than in just orally, with the idea that applying topically will limit side effects as the drug is less likely to spread system wide, rather than pill form that effects the whole body.
Oral Finasteride
Oral finasteride is commonly prescribed in a 0.5mg or 1 mg dosage to treat hair loss. It has shown promising results in many clinical studies, with users often experiencing a reduction in hair loss and, in some cases, regrowth. However, it is essential to recognize that finasteride is not licensed for use in women, particularly premenopausal women, due to potential risks associated with its use.
Suitability for Women
Postmenopausal Women: The most suitable candidates for oral finasteride are postmenopausal women. After menopause, hormonal fluctuations reduce the risk of birth defects, making it safer for women to consider this treatment option. Some studies indicate that postmenopausal women may benefit from oral finasteride in combating hair loss.
Side Effects in Women
While finasteride can be effective in treating hair loss, it is crucial to be aware of potential side effects, particularly for women. The side effects of finasteride can differ between men and women, and in women, these effects can include:
Hormonal Changes: Finasteride can cause hormonal imbalances that may lead to irregular menstrual cycles. Women may experience changes in their menstrual patterns, including heavier or lighter periods.
Breast Tenderness or Enlargement: Some women may notice changes in breast tissue, including tenderness, pain, or enlargement, as a response to hormonal alterations induced by finasteride.
Mood Changes: There is evidence suggesting that some women may experience mood swings or depressive symptoms when taking finasteride. This can be particularly concerning and should be discussed with a healthcare provider.
Sexual Dysfunction: Although more commonly reported in men, women may experience sexual side effects such as decreased libido or difficulties with arousal. It's important for women to communicate openly with their doctors about any changes in sexual health while on finasteride.
Potential Risk During Pregnancy: Pregnant women or those planning to conceive should avoid finasteride. The medication is classified as a category X drug, indicating that it can cause severe birth defects if taken during pregnancy, particularly affecting male fetuses.
Topical Finasteride
Topical finasteride, which is applied directly to the scalp, has gained attention as an alternative to oral finasteride. This delivery method is believed to minimize systemic absorption, potentially reducing the risk of side effects associated with oral administration.
Suitability for Women
Topical finasteride may be a more suitable option for women, especially for those concerned about the risks associated with oral medication. Some studies have shown promising results in women using topical finasteride, with fewer systemic side effects reported, but the side effects when used topically have not been widely researched at this point.
When Not to Take Finasteride
There are specific scenarios in which finasteride should not be considered for women, including:
Pregnancy and Breastfeeding: Finasteride is contraindicated in pregnant women or those attempting to conceive, as it can affect fetal development. Additionally, it is not recommended for breastfeeding mothers due to the potential for the drug to pass into breast milk.
Hormonal Disorders: Women with a history of hormone-sensitive conditions, such as certain breast cancers, should consult their healthcare provider before considering finasteride.
Pre-menopausal Women: Oral finasteride is not typically recommended for premenopausal women due to the potential risks and side effects.
Alternatives to Finasteride
While finasteride can be an effective option for some women, there are other treatments available for hair loss that should also be considered.
Minoxidil: A topical solution that stimulates hair growth by increasing blood flow to hair follicles. Minoxidil is often recommended for both men and women and is available over-the-counter.
Hair Transplant Surgery: For those seeking a more permanent solution, hair transplant surgery may be a viable option. Procedures like Follicular Unit Extraction (FUE) can provide natural-looking results.
Platelet-Rich Plasma (PRP) Therapy: This treatment involves drawing a small amount of blood from the patient, processing it to isolate the platelets, and then injecting the PRP into the scalp to promote hair growth.
LLLT Therapy: Low Level Laser Light Therapy has been shown to slow hair loss and promote hair regrowth and has very few die effects, but requires long term treatment to be effective.
Derma Roller: Derma Rollers and Micro needling both have a siliar effect and have shown to generate some regrowth in both men and women
Conclusion
In summary, finasteride can offer benefits for women experiencing hair loss, particularly those who are postmenopausal. While both oral and topical forms of finasteride exist, the choice of treatment should be made with careful consideration of individual circumstances, side effects, and the guidance of a qualified healthcare professional. Women should engage in open discussions with their doctors to determine the most appropriate treatment plan for their specific needs.
