Recovery and protection of photo-damaged hairs with keratin-encapsulated cationic liposomes.
Article in International journal of cosmetic science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveDaily sunlight exposure impacts the structural integrity and chemical composition of hair in both reversible and permanent manners. Although keratin-based treatments have been popularly used to repair damaged hair, their effects in the recovery of the hair damage caused by UV light have not been well studied. Moreover, limitations related to keratin penetration depth and duration of effect persist. Encapsulating active ingredients in liposomes has been shown to enhance their stability, bioavailability and permeability. Thus, we aimed to design cationic liposomes encapsulated with keratin to enhance the recovery effects of photo-damaged hair.
methodsWe prepared keratin-incorporated cationic liposomes (KLs) via high-pressure homogenization and assessed their physical properties via hydrodynamic size, zeta potential, electron microscopy and X-ray diffraction analyses. The physical and chemical damage level of hair samples before and after treatment, such as hair smoothness, protein degradation and lipid peroxidation, were subsequently investigated using electron microscopy and different spectroscopies.
resultsThe results indicated that the cationic liposomes fabricated by high-pressure homogenization method had combined unilamellar and multilamellar structures. Compared with the keratin solution, the KL suspension significantly improved the permeation of keratin into the cortex during a 24-h incubation. Moreover, 24 and 48-h UV-exposed hairs showed enhanced recovery when incubated with keratin liposomes for 24 h, as evidenced by the observation of a smoother hair surface using electron microscopy. We observed that treatment with keratin liposomes significantly reduced protein denaturation and lipid peroxidation in the photo-damaged hairs.
conclusionWe anticipate that cationic liposome-assisted keratin delivery may serve as an effective method for restoring photo-damaged hair in both the physical and chemical dimensions.
