Objectives: To assess the effectiveness of adipocyte-derived mesenchymal stem cells-conditioned media (ADSC-CM) formulation in telogen effluvium patients.
Methods: A retrospective cohort study was conducted at a dermatology clinic in Jeddah, Saudi Arabia. The study included 50 consecutive patients aged 20-70 years, who were diagnosed with telogen effluvium. All patients received five monthly sessions of the same commercial ADSC-CM formulation, using a standardized application protocol. Pre- and post-intervention changes in trichometry parameters were analyzed.
Results: There was a significant increase in mean hair density (up to 29.01 hair/cm2; effect size 0.7-1.0), cumulative hair thickness (up to 2.67 units; effect size 0.7-1.4), and the number of follicular hair units (up to 19.96%; effect size 1.0-1.3) in all scalp regions (p < 0.001), associated with a decrease in mean trichometry-derived Sinclair scale by 0.8-1.3 (p < 0.001). Positive outcomes were observed in 70%-92% of the patients depending on the parameter and scalp region. There was no impact of the patient's age on ADSC-CM efficacy.
Conclusion: ADSC-CM was successfully applied as a new treatment option for patients with telogen effluvium. These findings provide another therapeutic and research area for dermatologists to optimize the management of telogen effluvium and reduce its impact on patients.
