Well, if you didn’t thoroughly scrub yourself off in the shower, you would have some residual pheromones. Also, if you’ve been consistently wearing certain pheromones for a while now, people have been conditioned to behave a certain way around you, and will continue to do it for some time.
One you didn’t get them all off. You can also have build up on cloths if you didnt wash them even if you never sprayed directly to them.
Two if these are the same people they can retain a impression of you for a while after you stop using them. Since you not sending a new signal they are reverting to previous signals.
Three, They were giving you eye contact before but you were unaware of it.
Well, if normal clothes wash doesn’t get them off, then I guess that could be it. Or it could be the pheromones made them have a new signal, I dunno. Either way, this can save dosages
