PROPECIA blocks the formation of a key factor of certain types of male pattern hair loss (MPHL).
PROPECIA is the first pill that effectively treats MPHL on the vertex (at top of head) and anterior mid-scalp area.
PROPECIA blocks the formation of DHT in your scalp. Lowering the DHT appears to inhibit the further shrinking of affected hair follicles, (either regrowth of hair, 48% [134 out of 279], or no further hair loss, 42% [117 out of 279]) vs 25% (4 out of 16) on placebo (sugar pill), according to an assessment of photographs by an independent panel of dermatologists.
