Current Primary Outcome Measures (submitted: October 30, 2014)

• Change in Target Area Hair Count (TAHC) [ Time Frame: Baseline and Month 6 ]
  Changes from Baseline in TAHC [in number of non-vellus hairs] using digital image analysis at Month 6.
• Subject Self Assessment (Hair Growth Assessment [HGA]) [ Time Frame: Month 6 ]
  The subject's evaluation of treatment benefit via the HGA questionnaires at Month 6. Scalp hair growth is compared from baseline using the following 7-point scale: greatly decreased (-3), moderately decreased (-2), slightly decreased (-1), no change (0), slightly increased (1), moderately increased (2), and greatly increased (3).

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: October 30, 2014)

• Change in Target Area Hair Width (TAHW) [ Time Frame: Baseline and Month 6 ]
  Changes from Baseline in TAHW [in μm/cm2] using digital image analysis at Month 6.
• Change in Target Area Hair Density (TAHD) [ Time Frame: Baseline and Month 6 ]
  Changes from Baseline in TAHD [in intensity units] using digital image analysis at Month 6.
• Subject evaluation of treatment benefit via the Hair Growth Index (HGI) and Hair Growth Satisfaction Scale (HGSS) questionnaires [ Time Frame: Month 6 ]
  The subject's evaluation of treatment benefit via the HGI and HGSS questionnaires at Month 6. HGI: Hair growth is compared from baseline by three questions on a health outcome questionnaire, which are scored using the following 7-point scale: much less (-3), moderately less (-2), slightly less (-1), the same amount (0), slightly more (1), moderately more (2), much more (3). HGSS: Hair appearance/growth is compared from baseline by five questions, which are scored using the following 7-point scale: very dissatisfied (-3), dissatisfied (-2), somewhat dissatisfied (-1), neutral/neither satisfied nor dissatisfied (0), somewhat satisfied (1), satisfied (2), very satisfied (3).
• Investigator's Global Assessment (IGA) [ Time Frame: Baseline, Month 2, 4 and 6 ]
  Compared to Baseline, the investigator will assess the subject's scalp hair growth using the following 7-point scale: greatly decreased (-3), moderately decreased (-2), slightly decreased (-1), no change (0), slightly increased (1), moderately increased (2), and greatly increased (3).
