Brief Summary:
This study will assess the safety, tolerability, and efficacy of SM04554 at concentrations of 0.15% and 0.25%. Improved knowledge of the changes in hair counts and immunohistochemical analysis associated with androgenetic alopecia (AGA) before and after treatment with SM04554 and compared to placebo may lead to a greater understanding of the underlying mechanisms of action of SM04554.

  6. Change in number of indeterminate hair follicles [ Time Frame: Baseline, Day 91 and Day 135 ]
    Scalp biopsies obtained prior to initiating therapy, after 90 days of therapy, and after an additional 45 days off therapy will be compared to determine the change in the number of indeterminate hair follicles over the treatment and off-treatment periods.

  7. Change in density of hair follicles [ Time Frame: Baseline, Day 91 and Day 135 ]
    Scalp biopsies obtained prior to initiating therapy, after 90 days of therapy, and after an additional 45 days off therapy will be compared to determine the change in density of hair follicles over the treatment and off-treatment periods.

  8. Ratio of terminal to miniaturized hair follicles (indeterminate hair and vellus hair follicles) [ Time Frame: Baseline, Day 91 and Day 135 ]
    Scalp biopsies obtained prior to initiating therapy, after 90 days of therapy, and after an additional 45 days off therapy will be used to determine the ratio of terminal to miniaturized hair follicles during the treatment and off-treatment periods.

  9. Change in nuclear expression of beta-catenin [ Time Frame: Baseline, Day 91 and Day 135 ]
