How does body hair know to stop growing at a certain length, while the hair on your head keeps growing longer?

Everyone grows hair at different rates.  Pubic hair generally takes as long as the hair on your head if you have shaven it off or trimmed it.  To put it most accurate, it depends, but I believe average growth is 1/2 inch per month.

No to both. \n\nThe biggest difference is that before shaving, your hair is thinner at the tips.  When it grows back out from shaving, it's the same thickness at the tip as it is near your skin which makes it seem like it grows back in more.  Your # of follicles don't change.\n\nIf that were true, balding men everywhere would be shaving away, wouldn't they!

you lose 100 hairs a day.  usually, they are not noticed but with longer hair it shows up easier.  try getting a trim to remove split ends.  this will help prevent breakage.\n\np.s.  the more hair you lose, the head you get!

It's normal with aging.  As you get older the hair on your head decrease but in places like eyebrows, ears, nose, and often times the back as well, the hair increases.  I am not really sure of any reason other than nature

No, the hair on your head doesn't change if you cut it or not..\n\nIt might LOOK thicker because all the hair would line up, this happens to all hair..\n\nHowever it would not join back thicker..

No, you're hair isn't growing, but it is pulling away from the follicle, putting more of the hair on the outside making it seem as if your hair grew.

every person has 85,000 to 1,25,000 hairs on his head. As for as the head goes there is a lot of hair on the body.

I don't know how to prolong the hair regrowth but I have noticed that on my wife that the more she does it there is less hair that comes back each time.

It's normal. Having a pubic hair in your penis base is a sign that your body is growing and changing. It means that your slowly becoming a man.

My guess, and it's only a guess is that it traps our own unique scent, which then attracts "mates."  Obviously, we only grow hair under our arms at puberty, and what occurs at puberty is that our sex organs develop, so that's the rationale behind my answer.  However, I do not know the biological reason why humans have relatively long hair in their armpits!

No the actual hair doesn't grow back any faster or thicker.  But shaving can stimulate other hair follicles to grow darker.  The reason for colored hair is due to melanin produced at the site of the hair follicle which is then used in the production of the hair shaft.  This melanin isn't used in all hair, which is why some to a lot of hair looks white, blonde, or even clear on the body.  When the melaninocyte (the cells that produce melanin) are stimulated by UV rays (from sunlight), hormones (during puberty or genetic), or some other source, they begin producing different colored hairs, depending on what those cells are designed for (i.e. red, blonde, black, brown, etc).  When you have more hair follicles producing colored hair, it just appears that the hair has grown faster of thicker.

LOL, funny things what ya body does dont ya think!\nThe hair grows faster because the skin cells that react to the coldness of the atmosphere, then the hair cell inside the skin cell starts sprouting triggerd because of the nerves. The hair isnt is to keep your skin and nervous cells warm. \nHey and not just in antartica dude!\nI hope this helped you. \nKind Regards, Timothy H. (Age 12, W.A.)

Sweat is secreted by sweat glands in your skin.  The hair has nothing to do with  the secretion of the sweat.

This is a common misconception.\n\nNails, hair etc do NOT continue to grow after death - it is merely the illusion of your skin contracting around the follicles etc that makes it appear so.

You might not grow anymore. You might grow another 6 inches. Really, I can't tell you. Typically people stop growing in their late teenage years.

It is a myth that hair keeps growing after we die. As our bodies begin to decompose after death we loose moisture and skin begins to shrink but hair and nails do not shrink therefore making it appear to be growing.
