What this Trial Is About
Androgenetic alopecia (AGA) is a common cause of hair loss affecting up to 70% of men and 40% of women, mainly on the frontal and parietal scalp. This condition can cause significant emotional and psychological distress. Researchers are studying different therapies for AGA, including topical treatments, platelet-rich plasma, hair transplantation, and laser therapies like the thulium laser combined with growth factors. Despite its growing use, there are few studies assessing the benefits of thulium laser with growth factors and LED phototherapy. This study compares three treatment approaches: thulium laser alone, thulium laser combined with growth factor serum, and thulium laser with growth factor serum plus LED phototherapy. Each intervention consists of three sessions spaced six weeks apart. Participants will be randomly assigned to one of these three groups to evaluate the effects of these therapies on hair loss. Participants will attend sessions at baseline and follow-up visits at 1 and 6 months post-treatment. During these visits, researchers will measure hair density, hair thickness, and overall aesthetic improvement using a global scale. Pain levels during the procedures will also be recorded. The study aims to provide objective and patient-reported data on these laser therapies over a 6-month period.
