DHT actually is linked to some pheromones. More specific: androsterone is a break-down product of DHT.
Stumbled upon an old thread about pheromone biosynthesis a while ago. It’s an interesting read:
However mones barely penetrate the skin, so they don’t influence your hormonal cycle. Don’t think you have to worry about these products boosting your DHT level. Popular workout supplements like creatine do boost it though… For me a reason not to use it.
Also: DHT only plays a role in male pattern baldness with people that are genetically sensitive to becoming bald.
