De-sensitised to pheromones

Through regular use of pheromones, is it possible for an individual to be de-sensitized to their effects? My headaches don’t seem to be as bad as before, isn’t that a sign of desensitization?

Advice please. Gracias

Self effects get more tolerable after a while. You really start to notice this once you stop using mones after prolonged use, and start using it again.
