A Clinical Evaluation of the Safety, Efficacy, and Tolerability of the Soulflower Rosemary Redensyl Hair Growth Serum, Tetragain, in Healthy Female Subjects for the Treatment of Alopecia: Promoting Hair Growth and Reducing Gray Hair

The study assessed the Soulflower Rosemary Redensyl Hair Growth Serum (Tetragain™) in 32 healthy women with alopecia and partially gray hair over 120 days, showing significant improvements in hair growth rate, length, thickness, and reduced hair fall and graying severity, all with p < 0.001. Participants reported satisfaction and no adverse effects, indicating the serum's safety and efficacy. Despite the study's limitations, such as its single-arm design and small sample size, the serum appears promising for enhancing hair health and managing gray hair, with future randomized controlled trials recommended to confirm these findings.
