An Exploratory Preclinical In Vivo Pilot Study Evaluating the Hair Growth-Promoting Effects of Rosmarinus officinalis and Ricinus communis Combination.

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
backgroundHair loss is a common condition with significant psychosocial impact. Although pharmacological treatments such as minoxidil are available, their long-term use may be associated with adverse effects. Plant-derived products are widely used in traditional medicine for hair care; however, scientific validation of their efficacy remains limited.
objectiveThis study is aimed at evaluating the hair growth-promoting effects of a combination of Rosmarinus officinalis and Ricinus communis oils in a murine model. METHODOLOGY: Essential oil from R. officinalis was obtained by hydrodistillation, whereas fixed oil from R. communis seeds was extracted using Soxhlet extraction with hexane. Fifteen mice (n = 3 per group) were divided into five groups: rosemary oil, castor oil, combination (1 : 1), 2% minoxidil (positive control), and untreated (negative control). Treatments were applied topically once daily for 28 days. Hair growth was evaluated using hair length measurement, macroscopic observation, and standardized hair regrowth scoring. Data were analyzed using one-way ANOVA followed by Tukey's post hoc test. Statistical outputs are presented descriptively due to the small sample size and p values are reported for trend identification rather than inferential significance.
resultsThe combination group showed higher mean hair length (12.88 ± 0.79 mm) compared with R. officinalis (12.68 ± 0.25 mm) and R. communis (10.10 ± 0.22 mm) and showed similar trends to 2% minoxidil (13.06 ± 0.21 mm). One-way ANOVA showed overall group differences. Statistical outputs are presented descriptively due to the small sample size; p values are reported for trend identification rather than inferential significance.
conclusionThe findings suggest that the combination of R. officinalis and R. communis oils may promote hair growth in a murine model. The present findings are derived from a murine model and cannot be directly extrapolated to human use.
