Survey of the Hair Growth Stimulating Effects of Shampoo Containing Grapefruit Peel and Gleditsia Sinensis Essential Oils on Shaved White Mice

This study found that using grapefruit essential oil improved hair growth and length in a shaved white mice model compared to controls.

This study found that 10% Citrus aurantium peel oil significantly promoted hair growth in ICR mice by reducing the time needed for hair growth initiation and completion, and by increasing hair length, follicle diameter, and count, showing potential as a hair growth agent.

The study observed that Carthamus tinctorius extract-loaded lipid carriers promoted hair growth in C57BL/6 mice more effectively than minoxidil, although further research on humans is needed for confirmation.

This review discusses various natural extracts, such as peppermint, rosemary, wild cultivated ginseng, and others, for their potential hair growth promotion effects and calls for further exploration into combinations with fewer side effects.

This research explored hair loss and regrowth, highlighting the use of animal models like mice and rats to better understand hair physiology, shedding cycles, and potential treatments, with implications for human application.
