How does testosterone rise while shaving? Hair is dead, so it doesn't send signals saying that its been cut. Hair LOOKS like it comes back thicker because they're all cut at the same time and they grow back at the same time. Post those medical journals because they sound like bullshit
its that simple huh,search google,feel lucky,then take the info as fact.you are repeating everything that was stated on that site.how do you expect your argument to carry any weight or credibility?next time you want to pass some info around,do your research instead of hitting up a search engine.it's for your own good.I mean i'm trying to help you here.
when you shave your face,your facial hairs become even with the openings of the pores.Since the ends become somewhat split,they irritate the openings of the pores.When this occurs,blood rushes up and sometimes to the surface of the skin.You may not see your skin turn red,because the blood might not make it all the way up.Whats important here is once the blood rushes up,it will reach the facial hair follicles which in turn will trigger a part of the brain called the hypothalamus.the hypothalamus then sends a signal to your endocrine system and releases 2 hormones.The follicle stimulating hormone (FSH) and the luteinizing hormone (LH).These 2 hormones then influence the production of natural testosterone.Testosterone increases the thickness and growth of facial hair.
And no, testosterone does not affect hair growth on your head,only all the other hairs on your body such as pubic hairs,chest hairs,back hairs,etc...They basically run on the same mechanism.
