Pheromones are androgens mostly. No they do not change when they come in contact with skin or hair but they can convert to other androgens when they come in contact with bacteria.
I dont quite understand this question. I am assuming your asking how do others know its you that is sending the signal.

Because you put it on. Your consciously aware of that. Those around you pick it up as a signal from an outside source. They are not conscious of it however they feel a feeling and look for the source of that feeling.
IH doesn’t make you honest, thats just the name of it. It opens up deep communication. Again your aware its there and where it came from so you have more control over what you share. Others process it as you being trustworthy, easy to talk to and they connect with you so they tend to open up on deeper issues. Hence the name IH.
Those exposed to it know the signal is not coming from them just as they know when you speak the noise is not coming from them.
We have been communicating chemically from the beginning of time. Its not something we are conscious of doing just like you not conscious of making your blood flow or of the other functions of your body. You know about them of course because you learned about them but you dont have to consciously think about it to be able to function. So asking how can we read these signals is like asking how does your body know its needs to pump your blood. It just knows.
Its not really a chemical change for the wearer. You secrete all of the pheromones that are used at some point. Your brain knows what they signal and it can pinpoint where its coming from on a subconscious level. Using synthetic pheromones just gives you more control over the signal your sending and when your sending it.
We secrete different pheromones at different times naturally to express information about ourselves as well as about our nature. Not every person will respond the exact same to those signals. However if your wearing Ishine for instance and sending a warm open uplifting signal people tend to feel good and respond in kind.
It is related to the way humans process information and in that sense its mental because the type of pheromones used here are not going to change the physical. They are a form of communication that we are born with. A language in a way.
