The Investigator or a trained grader rated each participant's standardized global photographs for improvement from baseline for parameters like hair thinning, hair growth, impression of scalp hair coverage and overall perception of treatment benefit using a 1-to-7-point Likert scale. The score on the scale ranged from 1 (minimum) to 7 (maximum), that is, (1) Entirely Disagree; (2) Mostly Disagree; (3) Somewhat Disagree; (4) Neither Agree nor Disagree; (5) Somewhat Agree; (6) Mostly Agree; (7) Entirely Agree.

ITT population included all participants who were randomized and have at least one post-treatment administration evaluation.

Participants rated the parameters like appearance of hair, growth of hair, satisfaction with Hairline at the front of the head, satisfaction with hair on the top of the head and satisfaction with hair overall as an overall improvement from the baseline by conducting their own assessments by looking in a mirror and evaluating improvement from baseline using a 1 to 7-point Likert scale. The scores on the scale ranged from 1 (minimum) to 7 (maximum), that is, (1) Entirely Disagree; (2) Mostly Disagree; (3) Somewhat Disagree; (4) Neither Agree nor Disagree; (5) Somewhat Agree; (6) Mostly Agree; (7) Entirely Agree.

ITT population included all participants who were randomized and had at least one post-treatment administration evaluation.

Participants collected their hair full day, including after combing and hair-washing. Participants turned in these hair collections at each visit. The results were averaged weekly. Mean change from baseline in hair wash/shed hair count was reported at week 12.

The ITT population included all participants who were randomized and had at least one post-treatment administration evaluation.

Participant satisfaction with the treatment experience data was collected via a written questionnaire This questionnaire composed of 5-point Likert scale questions, as well as free-text responses. Participants were asked to determine overall satisfaction with the treatment. The choices were: 1-2 = Agree; 4-5 = Disagree; 3 = Neutral.

The ITT population included all participants who were randomized and had at least one post-treatment administration evaluation.

AEs were defined as any untoward medical occurrence associated with the use of a study product in humans, whether or not considered study product related. An AE could be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study product and would not imply any judgment about causality. An AE could arise with any use of the study product and with any route of administration, formulation, or dose, including an overdose. Thus any new sign, symptom or disease, or clinically significant increase in the intensity of an existing sign, or symptom would be considered as an AE. Any new clinically relevant sign or symptom suffered by the participant, which appeared after the study procedures was reported as an AE. Any worsening in scalp dryness or itch score from baseline was also reported as an AE. The Investigator or designee had the final authorization to determine if a reaction was considered an AE.

SP included all participants who were enrolled and received at least one dose of study product.
