Changes in hair weight in men with androgenetic alopecia after treatment with finasteride (1 mg daily): Three- and 4-year results
July 2006
in “Journal of The American Academy of Dermatology”
TLDR Finasteride increases hair weight and count in men with hair loss, with best results after four years.
The study examined the effects of finasteride on hair weight and count in men with androgenetic alopecia (AGA) over a period of up to 4 years. The results showed that finasteride treatment led to a significant increase in hair weight and count, with the greatest increase seen after four years of treatment. The study concluded that long-term finasteride treatment led to sustained improvement in hair weight compared with placebo, and that factors other than the number of hairs, such as increased growth rate and thickness of hairs, contribute to the beneficial effects of finasteride in treated men.
