Male pattern hair loss (Androgenetic Alopecia)

What is oral finasteride?

Oral finasteride is a FDA-approved treatment for male pattern hair loss or androgenetic alopecia. Since the inception of oral finasteride hair loss treatment in 1997, it has helped many individuals halt relentless hair loss and improve hair growth.

how does oral finasteride work?

One of the reasons for male pattern hair loss is the effect of dihydrotestosterone (DHT) on the hair follicles. Other reasons include genetics, compromised vascular supply around the hair follicle and reduced anagen phase. Testosterone in the body is converted to DHT by the enzyme 5-alpha-reductase. Oral finasteride works by inhibiting the action of the enzyme 5-alpha-reductase and therefore reduces the circulating levels of DHT and its effects on the hair follicle.

how effective is oral finasteride hair loss treatment?

Studies have shown oral finasteride 1mg/day to be effective in treating patients with androgenetic alopeica and long-term use of up to 5 years has shown significant hair growth and permanent stabilization of hair loss. A Japanese study of over 3000 males with hair loss demonstrated that 11.1% of subjects exhibited significant hair regrowth with finasteride use, 36.5% exhibited moderate growth, and 39.5% had only a slight increase in hair growth over a period of 3 years

how safe is oral finasteride?

Oral finasteride is a well-studied treatment for male pattern hair loss over more than 2 decades. Most patients tolerate the treatment well. In clinical trials, about 1.4% of patients had to stop the treatment due to side effects. The risk of loss of libido, erectile dysfunction and reduced ejaculate volume is less than 2%, and these symptoms usually improves over time.

what about dutasteride for hair loss?

Dutasteride, in particular, is noteworthy as it is approximately 3 times more potent against type II 5 alpha-reductase enzyme and 100 times more potent against the type 1 enzyme. It is often used for patients who have not experienced satisfactory results with finasteride. The adverse effect profile of dutasteride is similar to that of finasteride.

Topical Minoxidil has an interesting story. It was discovered by accident, as doctors were using the oral form to treat high blood pressure and noticed the incidental side effect of increased hair growth. While it is unknown how minoxidil actually works, it should be used for at least 6 months for maximum efficiency. It is common for hair to shed for the first 2-6 weeks when starting treatment, but treatment should be continued as it will slow progression of the hair loss and partially restore hair in some cases over time. Minoxidil treatment can be used for male and female pattern hair loss.
