Study of the efficiency of a peptide-based cosmetic product in topical therapy for diffuse alopecia

Background: Hair loss is a significant health problem; hence, individuals experiencing hair loss immediately visit a doctor for treatment. Diffuse (symptomatic) alopecia can be the result of various external and internal factors. A doctor should determine the cause of the hair loss and prescribe treatment, including topical agents.

Aim: to study the clinical efficacy of hair spray with peptides in the treatment of patients with diffuse alopecia and its effect on the trichogramma parameters.

Materials and methods: Thirty female patients with diffuse alopecia, aged from 18 to 59 years, were monitored in the Center of Medical Cosmetology of the I.I. Mechnikov North-Western State Medical University. In a controlled comparative study, the patients were divided into two equal groups. In group 1 (main), the drug of choice was a spray based on peptides; while in group 2 (comparison), a cosmetic product based on enzymes was applied. The drugs were used topically for 3 months. Patients were examined using questionnaires (objective assessment by the doctor and subjective evaluation by the patient) and photographs and by assessing the morphometric parameters of hair growth before treatment, 3 months after the start of treatment, and 1 month after treatment termination.

Results: In group 1, in the parietal zone, the hair density increased significantly by 19% after 3 months and by 23% after 4 months. The number of anagen hair increased by 8% after 3 months and by 16% after 4 months, with a corresponding decrease in the number of telogen hair compared to the initial level. In the occipital zone, the number of anagen hair increased by 7% after 3 months and by 13% after 4 months, with the corresponding dynamics of telogen hair compared to the initial level. The cosmetic product has been shown to be tolerated well, and no allergic reactions were noted.

Conclusion: The peptide-based spray can be recommended for patients with diffuse alopecia as a topical therapy.
