This study concluded that a hair-nourishing formulation combining virgin coconut oil and 4% chilli oil significantly enhanced hair growth in white rats over a 21-day period, while also exhibiting good physical stability under varying storage conditions.

This study reviewed evidence on hair oils' effects on hair health and found that coconut-based oils may protect hair during prewash by reducing porosity and improving tensile strength, while rosemary oil showed evidence for promoting hair growth in androgenetic alopecia.

This literature review found that combining coconut oil with various herbal extracts can promote hair growth in rats and rabbits, with different combinations producing varying hair length increases over 18 to 30 days.

This study found that a mixture of 80% coconut oil and 20% candlenut oil effectively stimulated hair development in Wistar rats, which may be attributed to the high lauric acid content in coconut oil.

This study found that using a formulated herbal hair oil, which includes ingredients like Nigella sativa and Cocos nucifera, reduced hair fall progressively over periods ranging from 15 to 90 days among 25 volunteers, showing greater efficacy than simple purified coconut oil.

In this experimental study using rabbits, the researchers evaluated hair tonic formulations containing cinnamon essential oil and virgin coconut oil, finding that formula 3 had hair growth activity exceeding the positive control, though overall growth activity differences were not statistically significant.
