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.
No that's a myth. Shaving is a nusiance because the hair does seem to grow back thicker.
Yes,that's a fact.
why would you want to grow long leg hair. but any way when you shave a few times it usually grows more after.
Honestly, it depends on how long your leg hair is. Most women do not let their leg hair get long enough to even begin to simply trim the hair. Shaving allows for smooth and more attractive legs.
That would be a razor.
There are not many other ways except for long and painful plucking. I suggest shaving, it's painless and works well. Hope this helps!
shaving generally makes hair shorter.
You would have to shave it before then. The only way is to wax then you wont have to shave as much.
Letting it grow.
About 4 days if you shave it... If you wax about a week...
Well, some people try to get rid of leg hair. But for now leg hair grows by it's time. I don't think something can make you leg hair grow faster because a lot of people don't want it.
