Brief summary:
The purpose of this study is evaluating the efficacy and safety of a topical herbal solution in males for the treatment of Androgenetic alopecia.

Detailed description:
This study will be done on male subjects with Androgenetic alopecia(AGA). The patients will be selected by volunteers attending the Dermatology department of Sina Hospital, and eligible individuals will be selected among them. Subjects were randomized to use either Topical Herbal Solution or Topical Minoxidil 5% for 36 weeks.

To our knowledge, this herbal solution for the first time covers all four major causes of AGA, including the 5α-reductase enzyme, androgen receptors, paracrine agents that affecting dermal papilla and hair cell apoptosis processes. Therefore it acts with the quadruple mechanism. The application of this new herbal solution for the treatment of AGA should be recommended.

Arms: arm 1: The patients will be applied 1 mL of solutions(Herbal and Minoxidil) at morning and evening intervals to the thinning hair areas of the scalp for 36 weeks. arm 2: The patients will be applied 1 mL of Minoxidil 5% solutions at morning and evening intervals to the thinning hair areas of the scalp for 36 weeks.
Interventions: intervention 1: Topical Herbal Solution intervention 2: Topical Minoxidil 5%
Intervention descriptions: intervention 1: Use Topical Herbal Solution every day in scalp hair loss areas for 36 weeks. intervention 2: Use Minoxidil 5% solution every day in scalp hair loss areas for 36 weeks.

1. STUDY OBJECTIVES: 
Evaluate the effect of the topical herbal solution on the prevention and treatment of 
androgenetic alopecia and comparison with 5% minoxidil  
2. STUDY DESIGN 
This study will be done on male patients with androgenic hair loss. The patients will be 
selected by volunteers attending the Dermatology department of Sina Hospital and eligible 
individuals will be selected among them. The participants will be randomly allocated (using 
random number tables) to two groups; the first group will receive a 5% minoxidil topical 
solution, and the second group will receive a 5% minoxidil topical solution plus the topical 
herbal solution for 36 weeks. The hair thickness will be measured to determine efficacy at 
baseline, 12, 24, and 36 weeks. The patient's questionnaire self-evaluation and side effects 
will also be evaluated. 
3. BACKGROUND AND RATIONALE 
Androgenetic alopecia (AGA) is mostly caused by miniaturization of androgen-sensitive hair 
follicles and common form of scalp hair loss. AGA can affect the quality of life, self-
confidence, and change in interpersonal and social relationships, especially among young 
people. AGA can be capable of affecting all races. The highest prevalence is observed in 
Caucasians. Finasteride and Minoxidil have been approved by the American Food and Drug 
Administration (FDA) for the treatment of AGA. Conventional therapy has many side effects. 
Herbal remedies can be more advancing than conventional when used topically on the scalp. 
Herbal remedies characterized by patient satisfaction, fewer side effects, and more 
mechanism in the treatment of AGA.

requested not to alter their usual routine hair care during the study period. 
• Subjects will be instructed to avoid the use of any prescripted and/or nonprescription 
therapeutic agents for preventing hair loss or hair growth during the study period. 
• Baseline hair thickness will be taken, and every three months, it will be repeated. For 
reproducibility, the target location on the scalp, where the hair thickness will be 
measured over time, consist of Intersecting three distances from the fixed anatomical 
locations. 
 
Treatment randomization 
Before the study begins, a random number table will be generated (in 1:1 ratio) for each study 
participant according to the subject number. The number will indicate whether treatment or 
control will be taken on the study groups. “0” represents a 5% minoxidil topical solution 
whereas “1” represents a 5% minoxidil topical solution plus the topical herbal solution. 
 
Blinding 
Dermatologist and the randomized subjects will be blinded to the subject’s allocation. It is 
necessary to use blinded treatment in order to reduce potential bias during data collection and 
evaluation of study outcomes.

mentioned above. 
 
10. SAFETY ASSESSMENT 
Any procedure has potential risks. According to the herbal origin, the topical herbal solution 
does not hold any chance of dangerous reactions or systematic disease. The threat from the 
use of topical solutions may include scalp itching, scalp dryness, and headache. The 
procedures used in this study may cause all, some, or none of the risks and side effects listed. 
Each study participant will be informed about the occurrence of these adverse events, and 
phone numbers will be given for answering any questions. Telephone contact with the 
investigator will be available 24 hours per day, seven days per week. Treatment for adverse 
events will be per standard of care from a dermatologist in the Department of Dermatology. 
 
11. STATISTICAL ANALYSIS PLAN (SAP) 
The statistical analysis will be performed using SPSS software 25 (SPSS Inc., Chicago, IL, 
USA). The normalcy of continuous data will be checked using the Kolmogorov-Smirnov 
Test. Mean (SD) will be calculated for all normally distributed continuous variables, e.g., 
age, duration of disease, hair diameter, etc. The unpaired (independent) t-test and paired t-test 
will be applied to compare the mean of hair diameter between two study groups and within 


8 
 
groups, respectively. For differences between self-assessment questionnaires, the Mann-
Whitney test will be performed. At or before the time of the Week 0 administration, subject 
demographics, hair diameter, and duration of AGA will be summarized. All statistical tests 
will two-side and will perform at a significance level of p-value < 0.05.

PART I: Information Sheet 
I am going to give you the information and invite you to participate in this research. You do 
not have to decide today whether or not you will participate in the research. Before you decide, 
you can talk to anyone you feel comfortable with about the research. 
Androgenetic alopecia (AGA), the most common type of hair loss, the drugs that are currently 
used to help people with AGA are not as good as we would like them to be. There is a new 
drug that may work better. The main reason we are doing this research is to discover if the new 
herbal solution is better than minoxidil, which is currently being used. 
Type of Research Intervention 
This research will involve the topical solutions that you will use on your scalp as well as the 
follow-up visits to the dermatology clinic at Sina hospital. 
Participant selection 
You are being asked to participate in this study because you satisfy our eligibility criteria which 
are: 
• Men 18 to 50 years old 
• Normal general health status 
• Presentation of androgenetic alopecia (Norwood II - V) 
• Have not been used any of topical product in the target region interfering with the study 
product in the last 12 months 
 
Voluntary Participation: 
Your participation in this research is entirely voluntary. It is your choice whether to participate 
or not. Whether you choose to participate or not, all the services you receive at this clinic will 
continue, and nothing will change.

Right to withdraw: 
You do not have to take part in this research if you do not wish to do it. You have the right to 
withdraw from this study at any time during the study without giving any reasons. However, 
you should talk to the research team before stopping the treatment. 
The study design 
All the topical solutions in the study will be divided into two groups. You will be receiving one 
of the solutions. The solutions will be randomly assigned to receive any one of the treatments. 
Randomization improves the scientific quality of research. Neither you nor we must know 
which of the two drugs you are given. This information will be in our files, but we will not look 
at these files until after the research is finished. This is the best way we have for testing without 
being influenced by what we think or hope might happen. We will then compare which of the 
two has the best results. 
Study Procedures: 
Since we do not know if the new AGA drug is better than the currently available drug for 
treating AGA, we need to compare the two. To do this, we will put people taking part in this 
research into two groups. The groups are selected by chance. 
The research takes place over nine months in total. During the study, you make three visits to 
the hospital. The plan, scheduled visits involve visits at 12, 24, and 36 weeks. At the end of 
nine months, the research will be finished. 
Once you are enrolled in the study, you will be required to follow the instructions. You will 
apply 1 mL of solution at morning and evening intervals to the thinning hair areas of the scalp 
for 36 weeks. You will not be permitted to use your routine hair cosmetics products and will 
be requested not to alter your regular hair care during the study period. 
You will not be allowed the use of any prescripted and nonprescription therapeutic agents for 
preventing hair loss or hair growth during the study period. Furthermore, you will not be 
allowed to take any medications other than the ones prescribed by the investigator. If you need 
to take some treatment, you must consult the investigator before taking that treatment. 
You may have to come to the hospital for examination and investigations apart from your 
scheduled visits if required. 
Cost to the participant 
You will not be required to pay for the medications. In case of any adverse event occurring due 
to the study medications, treatments are free and will be per standard of care from a 
dermatologist in the Department of Dermatology. 
Side Effects 
Some of the common adverse effects of topical solutions on the scalp: 
• Itching, redness or irritation at the scalp 
• Unwanted hair growth elsewhere on the body 
• Temporary hair loss

Risks 
By participating in this research, you may be at higher risk than you would otherwise be. There 
is, for example, a risk that your disease will not get better and that the new medicine does not 
work even as well as the old one. While the possibility of occurrence this happening is very 
low, you should still be aware of the option. 
Benefits 
If you participate in this research, you will have the following benefits: the treatment benefit 
and free investigations. There may not be any benefit for you, but your participation is likely 
to help us find the answer to the research question.  There may not be any benefit to the society 
at this stage of the research, but future generations are likely to benefit in providing safe, cost-
effective, and readily available to treatment AGA. 
Cost to the participants 
You will not pay any fees for interventions. In case of any adverse event occurring due to the 
study medications, you will be provided per standard of carefree treatment at the department 
of dermatology, Sina hospital. 
Reimbursements 
If you would like to participate in this study, you will not give any gifts, money, or travel grants.
