TLDR The caffeine content in anticellulite gels is 0.7-1.7% and in hair-care products is about 1.0%.

In 2020, a study was conducted to determine the exact caffeine content in hair care and anticellulite cosmetic products, as its exact content is not usually declared on product labels. The study used a solid-phase extraction (SPE) procedure for caffeine extraction and high-performance liquid chromatography (HPLC) determination in anticellulite gels, shampoos, and hair balsam. The results showed that the caffeine content in cellulite reduction gels ranged from 0.7-1.7%, while in hair-care products, it was approximately 1.0%. This information is crucial as daily exposure to caffeine from all sources may approach health reference values.
