Allergic to any component of minoxidil, finasteride or excipients (such as a history of alcohol allergy), or allergic constitution; 2. According to the researcher's judgment, the participant's head has any of the following conditions that may interfere with the study evaluation: A. History of scalp skin abnormalities or scalp skin diseases, such as obvious dermatitis, trauma or infection near the administration site; B. White hair in the hair loss area that obviously interferes with the study evaluation; C. Secondary hair loss, such as hair loss caused by malnutrition, drugs, endocrine (hypothyroidism or hyperthyroidism, parathyroid or pituitary dysfunction), iron deficiency anemia and systemic lupus erythematosus; D.

Use of medical shampoos or solutions containing other ingredients such as ketoconazole or similar ingredients that may interfere with efficacy evaluation within 1 week before the first medication; F.

Participants who have received CG2001 treatment before. 4. Other diseases with poorly controlled conditions that may affect the safety and efficacy evaluation of the trial drugs, such as malignant tumors, or poorly controlled diseases in the circulatory system, nervous system, blood system, digestive system (such as inflammatory bowel disease), immune system, mental system, etc. (except for completely resected carcinoma in situ, localized prostate cancer that has received radical treatment and has no disease recurrence, completely resected basal cell or squamous cell skin cancer, malignant melanoma with a complete remission time of more than 10 years, and other malignant tumors with a complete remission time of more than 5 years); or participants who plan to undergo surgery during the study; or within 3 months before screening, the weight loss exceeds 10% of their original body weight; 5. Physical examination, vital signs, 12-lead electrocardiogram (ECG), blood routine, urine routine, blood biochemistry, and sex hormone test results during the screening period are abnormal and clinically significant (especially for participants with anemia), and the researchers judge that it will affect the safety assessment; 6. History of drug abuse, alcoholism or drug abuse within 5 years before screening (Note: alcoholism includes binge drinking and heavy drinking.

Participated in or is participating in other interventional clinical trials (including drugs and medical devices) within 1 month before screening; 8. The researcher believes that there are any other reasons that make the participants unsuitable for participation in this study.
