In a 24-month clinical study of Propecia on 1,215 men with varying degree of hair loss in the vertex of the scalp, 83% of the participants reported the same of higher hair count versus only 23% of the control group. Most subjects reported an increase in the amount of hair and decrease in hair loss.

A 5-year clinical study demonstrated the effectiveness of PROPECIA.
* 9 of 10 men who took PROPECIA had visible results—either regrowth of hair (48% [134 of 279]) or no further hair loss (42% [117 of 279])—vs 25% [4 of 16] who took a placebo (sugar pill), according to an assessment of photographs by an independent panel of dermatologists.
* 2 of 3 men who took PROPECIA regrew hair, as measured by hair count. All of the men in the study who were not taking PROPECIA lost hair.
* A majority of men who took PROPECIA were rated as improved by doctors—77% (210 of 271) vs 15% (2 of 13) of men who took a placebo.
* A majority of men who took PROPECIA reported that their bald spot got smaller, their hair loss slowed down, and the appearance of their hair improved.
bIn FDA-reviewed clinical trials, 2 of 3 men who took PROPECIA regrew hair, as measured by actual hair counts, whereas all of the men in the study who did not take PROPECIA lost hair.

How Propeica/Finasteride Works:
Finasteride's hair-raising success is due to its ability to specifically inhibit Type II 5-alpha-reductace, the enzyme that converts testosterone into a more potent androgen dihydrotestosterone (DHT). Propecia's 1 mg dose of finasteride can effectively lower DHT levels by as much as 60% when taken daily. It is DHT that shrinks or miniaturizes the hair follicle, which eventually leads to baldness .This 60% reduction in DHT has proven to stop the progression of hair loss in 86% of men taking it the drug during clinical trials. 65% of trial participants experienced what was considered a substantial increase of hair growth.

Clinical trials in male pattern hair loss
Various studies have shown the beneficial effects of Finasteride on reversing the pathogenesis of hair loss in male androgenetic alopecia. Most of these studies show the effects of Finasteride in stimulating a substantial amount of hair re-growth, reaching its peak efficacy after 1 year of treatment, and slowing the progression of hair loss thereafter.
* Three recent double-blind, placebo-controlled clinical trials have demonstrated that 1 mg Finasteride taken daily for at least 12 months prevented progression of hair loss and produced significantly greater increase in hair counts in comparison with placebo in men with mild to moderate hair loss. Photographic evaluation of subjects after 1 year of treatment showed clinical improvement in 48 percent as opposed to 7 percent with placebo. The percentage of subjects who showed progress with this treatment increased to 66 percent by the end of the second year.
* A study measuring hair counts using macrophotographs found that with the treatment of Finasteride there was an increase in both total and anagen hair counts as well as an increase in the anagen to telogen ratio. This study showed that Finasteride probably has the capacity to stimulate conversion of hair follicles into the anagen phase, possibly through reversion of the decrease in anagen phase and the increase in lag phase.
* A study of scalp biopsies found that Finasteride stimulates an increase in terminal hair counts and a decrease in vellus hair counts.
* Findings from another study using hair count and hair weight as an objective measure of outcome demonstrated that both hair count and hair weight increases, with a larger extent of increase achieved in hair weight. This proves the ability of Finasteride to reverse the miniaturization process, producing hair of greater length and thickness, and possibly with a greater growth rate.

Puedo decir, primero, que no es infalible, aunque es mas probable que notes, ya sea una "congelacion" del avance del estado actual y posiblemente recuperacion de nuevo cabello, a que suceda lo contrario, si me guio por las estadisticas. Lo mejor seria, como minimo, usarlo durante un año, y ver que progresos hubo, aunque incluso con plazos mayores a este, es posible notar una mejoria adicional. En mi experiencia, lo uso desde hace 14 meses, y definitivamente he notado progresos, fijate como te va a vos mas adelante, no hay que ser pesimista
, todavia te falta un largo trecho antes de juzgar los resultados...
Un saludon.
