Hair holds onto fragrance for longer because it doesn’t have the natural turnover, oils and warmth that skin has, all of which gradually work a scent off skin through the day.

What makes hair such a good carrier

Skin sheds cells constantly and produces its own oils that interact with and eventually break down fragrance molecules. Hair strands, being largely inert protein, don’t do this in the same way, and their texture actually traps scent molecules more effectively than smooth skin does. That’s why a light mist through the ends of your hair in the morning can still be noticeable that evening, long after the same spray on your wrist has faded.

The caveat worth knowing

Alcohol-based sprays can dry out hair with regular use, so it’s worth spraying into a brush and running it through rather than spraying directly onto your scalp or lengths repeatedly. A hair mist formulated for the purpose, where one exists, is gentler than a standard eau de parfum used the same way.
