Yes. It can cause it to become darker and thicker.
No. Yawning does not cause leg hair to grow. What does cause leg hair to grow (either thicker or darker) is shaving, genetics, and your overall hormones in your body.
Ingesting semen has been known to cause thicker hair in women. Additionally, semen isn't very good for your plumbing. Swallowing is preferred to spitting. Think of the environment!
ur gay, and no except when the guy gives you an STD that can cause your hair to fall out. Look up photos of people with Syphilis.
No, it doesn't. Shorter hair often seems thicker so, when you cut your hair it may feel thicker, but it's not. Also when the ends of your hair are even this makes your hair feel thicker.
To achieve an appearance of more hair on your arms and legs, simply shave them. This will cause your hair to grow back thicker, darker and fuller. Make sure your hair is healthy before doing so as shaving unhealthy hair might cause damage to it when it goes through it's regrowth stage.
It will not make your hair thicker or thinner. it will only do that if you over process your hair.
By washing it. Eww why does your mom have semen in her hair?!?! Nope, nevermind. I don't want to know.

Nothing that you can put on from the outside will make your hair grow thicker. (With the possible exception of Minoxidil.)
No it does not.
