Dead stuff doesn't grow. Instead, what is perceived as "growth" is acually the surrounding tissues receding, or shrinking, as a result of moisture loss from the once living surrounding tissue. Hair and nails are mostly protein (keratin) and contain very little moisture (in comparison to skin cells) and thus don't shrink.

you can do nothing to change the rate at which your hair grows.  Sorry.

Old dude has no idea of whether or not it's irritating or not when it grows back.  But waxing it is the best way to remove hair.  It hurts, but it lasts for up to a month, depending on how fast it grows.

Not my area of expertise but I have heard that the human body can last a maximum of 120 years.\n\nJust like the Terminators batterys.\n\nI plan on living to 100...or more

I think it all depends on the person. Some people grow hair over night literally. I think mine takes awhile to grow. But people who know me and see me daily tall me my hair grows fast. In the winter I let my hair grow as well as growing a full beard. During the summer I shave my head and face. I do keep a van dyke. Either way I find that I need to sahve every other day. As far as length I can;t really tell ya that. But it does grow quick enough

4-6 weeks is great you could also go up to three months inbetween trims but just remember your hair grows on average of 1/2 inch a month so just trim those ends unless you are african american and your hair grows about 1/4 inch a month. Also look into getting a good deep conditioner at a local salon and they can help you pick out the best one for your hair type.

It may never grow back.  Probably won't actually.  If it does start to grow back, it will take several months before it is completely grown out again.

it said that even if you die, your hair would remain so maybe it is ageless.

No, the hair grows from the follicles in your scalp.  The hair hanging out is technically dead.  That's why it doesn't hurt when it's cut.  However, it appears you're hair grows faster when you cut it because the split ends are cut off & while you're hair grows at different rates in different hairs, when it's neatly trimmed, it looks better & it seems to look like it's growing faster afterward.  But it's just an illusion.

My cousin is a licensed hair dresser and says the average hair one looses is about fifty hairs a day. That is without constant brushing and not wearing a hat most of the time.

Yes, hair will start growing on the palm of his hand.\n\nHe better stop now, or every one will know what he has been doing.

Ummm... since everyone's idea of "reasonable length" is different, your question is vague.\n\nHair grows at an average of 1 inch per month if you are less than 30 and about 1/2 inch per month if you are 30 or older.\n\nThis assumes you have a full head of hair (are not balding) and that you are a man.\n\nNow you can decide what the "reasonable length" is and apply the info above.\n\nIf this is the best answer, please vote it the best. Thanks!

NO! It only looks like hair and fingernails continue to grow after death. What causes this is that the skin drys up and shrinks, so it looks like the hair is growing. All cells are dead

Depends on how healthy the hair is. Most thinner hair will break off when it grow too long from the root.  \n\nCheck out the Guiness Book of World Records online to find out who has the longest hair in the world today.

humans are born with hair. it may be miniscule, or ridiculously fine, but its definitely there. by hair, we don't just mean on the top of the head, hair can be anywhere on the body, including the fine hairs on your arms and stuff.\nthe most hairless mammal i can think of is a whale; they only have hair on their lips.
