Hair greying associated with rosemary use: a cross-sectional study in Saudi Arabia.
Article in Dermatology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The sociological and psychological consequences of premature hair greying (PHG) are significant. PHG has been linked to various intrinsic and extrinsic factors, including genetic predispositions and environmental influences. The widespread use of hair growth-stimulating products may impact the hair greying process. This cross-sectional study aimed to determine the prevalence of hair greying among rosemary users in the Saudi Arabian population. A self-administered questionnaire was distributed among the sample population in the form of an online survey. This questionnaire included sociodemographic data (e.g., age, gender, and education), the use of several types of rosemary, and the outcomes. A total of 994 participants completed the survey, the majority of whom were female (94.4%). Participants aged between 18 and 24 years represented 64% of the sample. Hair loss was reported by 75.4% of respondents. More than half (58.7%) reported using rosemary, particularly rosemary oil, as a treatment. Among those who used rosemary, 22.8% reported experiencing hair greying. Increasing age emerged as an independent risk factor for PHG. However, multivariate regression analysis showed that the use of rosemary oil was associated with a reduced likelihood of hair greying. Approximately 25% of rosemary users developed PHG, and individuals in the early to middle-age range with a bachelor's degree or higher had a 1.5 to 3.5 times greater risk of hair greying. Nevertheless, the use of rosemary oil appeared to mitigate this risk. Additional observational studies are needed to validate the high regional prevalence of hair greying, potentially associated with rosemary use.
