Fifty Participants provided feedback on its performance across various parameters, ensuring a comprehensive evaluation across diverse hair types.

Study Methodology

A four-week prospective interventional trial was conducted with 50 participants to assess the efficacy of Zeo Shampoo on hair and scalp health.

Participants followed standardized usage instructions, and subjective feedback was collected via structured questionnaires at various intervals. The study included diverse hair types to ensure broad applicability.

Participants rated the shampoo on a 1–5 scale for shine, volume, hydration, texture, and cleanliness. Yes/no questions addressed negative reactions, softness, silkiness, oil control, and color retention.

Additional assessments included fragrance, texture, overall satisfaction, and repurchase intent. Responses were anonymous to maintain confidentiality. To ensure accurate results, adherence to the prescribed regimen was monitored. Any deviations were recorded along with reasons for changes.
