Ozonated Oil Emulsion for Seborrhea in Women (OOSE)

2026年10月20日 更新者：Chadi Khatib

A Randomized, Double-Blind, Placebo-Controlled Trial of an Ozonated Oil-Based Emulsion With Biotin for Seborrhea Management: Chemical Characterization, Stability Profiling, and Clinical Efficacy in Adult Women

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.

详细说明

BACKGROUND:

Seborrheic scalp conditions are common among adults, causing excessive oiliness and social discomfort. Current treatments use synthetic surfactants that may damage hair and scalp barrier. Ozonated oils represent a "green chemistry" approach that modifies natural oils to create bioactive compounds with antimicrobial and sebum-regulating properties.

INTERVENTION:

The study product is a low oil-in-water emulsion containing:

  • Ozonated oil blend (7%): Moringa oleifera, Triticum vulgare, Olea europaea, Capsicum annuum oleoresin
  • Biotin (0.1%): Vitamin B7 for keratin synthesis
  • Placebo: Identical base without ozonated oils and biotin

STUDY DESIGN:

Single-center, randomized, double-blind, placebo-controlled parallel-group trial conducted at the Research Unit of the Syrian Scientific Society for Medicinal Herbs (SHAMNA), Aleppo, Syria, between April and May 2024 (screening and enrollment: April 6 - May 18, 2024), under institutional authorization from Manara University Faculty of Pharmacy.

PARTICIPANTS:

66 adult women (18-40 years) with objective sebum ≥200 μg/cm² and self-reported daily hair washing due to oily scalp. Female-only enrollment to minimize sex-based variability in sebum production.

PRIMARY ENDPOINT:

Percent change from baseline in sebumeter-measured scalp sebum content at Week 6.

SECONDARY ENDPOINTS:

Hair manageability, shine, scalp comfort (0-10 scales), and Investigator Global Assessment.

STATISTICAL ANALYSIS:

The primary endpoint (percent change from baseline in Week 6 sebum) was analyzed by ANCOVA with baseline sebum as covariate, following FDA guidance on covariate adjustment. Missing Week 6 data were handled by Multiple Imputation by Chained Equations (MICE; m = 30). Continuous secondary endpoints (hair manageability, hair shine, scalp comfort) were analyzed by baseline-adjusted ANCOVA on observed cases at Week 6, with treatment group as a fixed factor and the corresponding baseline score as a continuous covariate. Binary IGA success was analyzed by logistic regression in the per-protocol population. Multiplicity was controlled by the Hochberg procedure. Seven pre-specified sensitivity analyses (observed-case, per-protocol, MNAR delta-adjustment, worst-case, extreme worst-case, best-case, and multi-covariate ANCOVA) confirmed robustness.

KEY FINDINGS:

Active treatment reduced scalp sebum by 28.5% vs. 9.8% with placebo (adjusted between-group difference: -19.0%, 95% CI: -22.2 to -15.8, p<0.0001, ITT with MICE), exceeding the pre-specified 15% clinically meaningful threshold. All secondary endpoints favored active treatment after multiplicity adjustment.

LIMITATIONS:

Single-center, female-only, 6-week duration. Generalizability to males and long-term safety require further study.
