Brief Summary
This study evaluates a new ozonated oil-based hair cream for women with oily scalp (seborrhea). The cream contains natural oils (moringa, wheat germ, olive, and chili extract) treated with ozone, plus biotin (vitamin B7). 66 women aged 18-40 years participated in this 6-week study. Participants were randomly assigned to receive either:
- The active cream (ozonated oils + biotin), OR
- A placebo cream (without active ingredients) Neither the participants nor the researchers knew which cream was given (double-blind). Participants applied the cream to their scalp every evening for 6 weeks. The main goal was to measure changes in scalp oil (sebum) production at Week 6 compared to baseline. Other outcomes included hair manageability, shine, and scalp comfort. Results showed that the active cream significantly reduced scalp oil by 28% compared to 10% in the placebo group. The cream was well-tolerated with only mild side effects (scalp irritation in 6% of active group). This study suggests that ozonated oil emulsion may be a safe and effective cosmetic option for managing oily scalp in women.

Outcome Measures
Primary Outcomes (1)
Percent change from baseline in scalp sebum content measured by Sebumeter
Objective measurement of scalp sebum production using Sebumeter SM 815 (Courage+Khazaka, Germany). Three standardized sites (vertex, left and right parietal regions) measured and averaged. Negative values indicate sebum reduction. Pre-specified clinically meaningful threshold: 15% absolute reduction.
Baseline (Day 0) and Week 6
Secondary Outcomes (4)
Hair shine score (investigator-rated)
Baseline, Week 2, Week 4, Week 6
Scalp comfort score (participant-reported)
Baseline, Week 2, Week 4, Week 6
Investigator Global Assessment success rate
Week 6
Hair manageability score (investigator-rated)
Baseline, Week 2, Week 4, and Week 6
Other Outcomes (3)
Adverse event rate
Throughout 6-week study period
Scalp irritation score

Study Arms (2)
Ozonated oil-based cosmetic emulsion
EXPERIMENTALLow oil-in-water emulsion containing ozonated natural oils (Moringa oleifera, Triticum vulgare, Olea europaea, Capsicum annuum oleoresin) plus biotin 0.1%. Applied 5g to scalp evening, overnight, rinsed morning for 6 weeks.
Matched vehicle control
OTHERIdentical base formulation with caprylic/capric triglyceride and isopropyl palmitate to match total oil phase (8%), rheology, and cosmetic elegance. Same application protocol: 5g evening, overnight, 6 weeks.
Interventions
Low oil-in-water emulsion containing ozonated natural oils (Moringa oleifera 3%, Triticum vulgare 1.95%, Olea europaea 2%, Capsicum annuum oleoresin 0.05%) plus biotin 0.1%. Applied 5g to scalp evening, overnight, rinsed morning for 6 weeks.
Identical base formulation with caprylic/capric triglyceride 6% and isopropyl palmitate 2% to match total oil phase (8%), rheology, and cosmetic elegance. Same application protocol: 5g evening, overnight, 6 weeks.
Eligibility Criteria
