Finasteride for Hair Loss in Women
Female Pattern Hair Loss (FPHL) is a significant global issue impacting many women. Traits of FPHL include thinning hair across the crown and parietal scalp, with the frontal hairline usually staying intact. As women get older, the occurrence of FPHL tends to increase, with predictions suggesting that half of all women will suffer from FPHL at some point in their lives.
The drug finasteride's role and effectiveness in treating FPHL at various stages has been a subject of research. This artificial compound works by blocking type II 5-α-reductase, stopping the conversion of testosterone into dihydrotestosterone (DHT), which can result in a decrease in scalp DHT levels and a boost in hair density in men with androgenetic alopecia (AGA).
Even though Finasteride is primarily used for treating AGA in men, it has also been utilized as an alternative treatment for FPHL. Both individual cases and broader studies have reported encouraging results, such as increased hair density and less hair loss, in women, regardless of whether they have hyperandrogenism.
There is a need for more research to establish the optimal therapeutic effectiveness of Finasteride in treating FPHL, as well as how it works in different age groups. However, it can be a viable alternative treatment method, particularly for postmenopausal women and those who want to avoid systemic side effects.
Pharmacology and Mechanism of Action of Finasteride
Finasteride is a synthetic compound classified as a 4-azasteroid. Its medical effects are derived from its ability to inhibit type II 5-α-reductase, a function that blocks the conversion of testosterone into dihydrotestosterone (DHT). This process occurs in the skin, liver, and prostate gland. The importance of this action is seen in the treatment of hair loss, given DHT's role in causing hair thinning seen in female pattern hair loss (FPHL).
The drug's behavior in the body, or pharmacokinetics, has been extensively studied, particularly for treating androgenetic alopecia (AGA) in men. When consumed orally, Finasteride's maximum plasma concentration is reached about 1-2 hours post-ingestion, and it achieves a steady state within three days. A daily dose of 5 mg finasteride for AGA patients results in a 43% decrease in scalp DHT levels at 28 days and up to 65% at 42 days. The bioavailability of this drug is 80%, and its absorption is not significantly influenced by food intake.
Comparing Finasteride with other hair loss treatments has yielded encouraging results for both men and women. It is officially approved for treating AGA in men and is increasingly used, albeit off-label, for treating FPHL. Several studies have reported that finasteride use led to increased hair density, decreased hair shedding, and overall clinical improvement in women with FPHL. However, it's essential to highlight that Finasteride's use in women is not officially approved, and more studies are required to confirm its optimal therapeutic efficacy and long-term safety.
Finasteride works for FPHL by inhibiting type II 5-α-reductase and blocking testosterone's conversion to DHT. Its pharmacokinetics have been thoroughly examined for treating AGA in men. Finasteride has shown promising results for women with FPHL compared to other hair loss treatments. Still, its use in women is not officially approved, and more studies are necessary to understand its effectiveness and safety in this group comprehensively.
Therapeutic Efficacy of Finasteride in FPHL
Finasteride has demonstrated encouraging potential in treating female pattern hair loss (FPHL), although its efficacy still needs further confirmation through more detailed studies.
