Hi pj. 
Welcome to the forum.
Anyplace ya gotta pulse is a good place to apply pheromones. Neck, wrists, inner elbows, cleavage if you have any…lol. Also back of hands if you’re going to be covered up and hair is very diffusive. Go to the stickies at the top of the men’s forum…a wealth of information there.

Oh Bella, you’re making me think of cleavages now.
Yo pj, for A314 I recommend the hair just let his drop onto your and leave it. For most of the products you listed can be placed onto the hair except for TUTH. It has none and can be very sticky. Try it one time and see what people talk about. Oh and don’t try more than once because it can leave you to OD.
from what I read hair is the best place for maximum diffusion and effects, depends on the individual, but most of the time I just apply to my wrist and neck.
applying to hair, does it have any side effects like loosing hair in the sparyed area over time, or thinning of hair over time…just wondering
I don’t think applying pheromones in moderate amounts to your hair could have any negative effects.
A314 on your hair… now that’s new. I tried various application points for A314 and found my wrists to be the best. As for -none products like TUTH and Ammo I find the chest application to be quite potent.
Try thinking of baseball…lol. 
Alcohol containing products, in general, have a tendency to dry out the hair when frequently applied. My favorite application point for a lot of pheromones, especially Instant Honesty, is the back of my hair. And, yes, tres diffusive. Great in winter, BTW, when you’re all covered up. Hair, wrists and the back of your hands. Just make sure, if you do it often, that you wash your hair well and condition and you should be fine. Seriously, I do it all the time. I have lotsa hair and it’s soft and shiny, np. I do not reccommend putting any products that contain -none in your hair, including A314. Be careful. It sticks like a mother. And you could unknowingly OD, even wearing it on your chest (chest hair?) and skin if you don’t srub your application points well…it can build up. You can put it on your chest, but I’d try to aim a little higher up just under the neck…remember srub well. And nev..ah put it in your pits or…there. 
Ya dun wanna “haunt” yourself, or others, by having it… literally… stick around.

I think it also depends on the hair (if you have any 
)
for example Asians usually have thin, straight, smooth, soft, fine hair, where as others may have very curly “hard” hair for example.
I have curly hair but when I get my hair cut done I tell the stylist to use textured clips to make it straight.
The application point of A314 to the top of my head is great. I get a lot of great hits from it. Oh and Usually I workout almost everyday of the week, so I shampoo and condition my hair pretty well and I think it gets A314 out of my hair. I didn’t know there was -none in A314…
