ClinConnect Summary

This clinical trial is studying the effects of Chinese herbal treatments on hair loss and gray hair over a period of six months. Researchers will enroll 152 adults, aged 18 to 60, who experience hair loss, including those with gray hair. Participants will be randomly divided into four groups, and each group will receive a combination of oral capsules and a hair tonic to use as directed. Throughout the trial, participants will have three in-person visits where their hair growth will be assessed through tests and photographs. Additionally, 10 participants from each group who have gray hair will have special assessments to see if there are any changes in their hair color.

To be eligible for the trial, participants must understand the study's purpose and procedures and sign an informed consent form. They should have a minimum hair length of 5 cm and meet specific criteria related to hair loss patterns. Women must also have a certain classification of hair thinning, while men must meet different standards. It's important to note that individuals who are pregnant, breastfeeding, or have certain medical conditions that cause hair loss will not be able to participate. Overall, this study aims to gather important information about the potential benefits of these herbal treatments for managing hair loss and gray hair.
