Propylene glycol in hair products acts as a humectant, which means it helps to retain moisture in the hair. It's commonly used due to its ability to absorb excess water and maintain moisture levels in hair strands. This can make hair feel softer and appear more hydrated. However, some individuals may find their hair or scalp reacts sensitively to propylene glycol, so it's recommended to perform a patch test if you're trying new products containing this ingredient.
