Yup and mine are danceing on my head\n\nofcourse not\n\nHair consists 90% of a biological polymer, α-keratin, and about 10% water, which modifies its mechanical properties. This α-helically coiled protein is further wound into supermolecular coiled-coil microfibrils, many of which are held together with a protein glue to form long macrofibrils, which are packed inside dead hair cells about 100 µm long by 3 µm across. Several of these associate to form one strand of hair, which is covered with tiny surface scales. The ends of individual keratin chains are high in the amino acids proline (an α-helix breaker) and cysteine. Adjacent keratin chains are held together by many disulfide bonds bridging their cysteines. These links are very robust; virtually intact hair has been recovered from ancient Egyptian tombs. Different parts of the hair have different cysteine levels, leading to harder or softer material.

Yes, your muscles tighten up, especially around your neck and head, cutting down the circulation of the blood. Really kills the hair folicles. Do some stretching exercises every day to keep the muscles loose and the blood flowing.

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.

I wouldn't know.  Surprisingly my head (and the rest of my body) are all still intact. Thank you for asking. \n\nAlso thank you for the easy 2 points.  Can I have the other 10? Pretty please? :) Okay granted my answer will not be the funniest, but at least I'm asking you nicely.

Yes, follicle cells like all cells have a life cycle. They only live for a period of time, if they don't then you'd have cancer. Once the follicle cell dies the hair falls off preventing it from growing longer.\n\nbtw, can't u answer with "God is amazing like that" for every question? Please.... I guess God is great so you don't have to think.

Hi\nI am a tattoo artist and I have never heard of any case where dieing your hair has interfeared with a tattoo. Now If the tattoo is on your head and its still healing then I can understand you would have a few problems. But as long as the die dosent get on a healing tattoo your fine.\n\nwww.studiomaxx.ca

Very good.  You will be bald before a single strand of new hair pops up.

Long after you're dead and rotted, and no longer care,  \nno need to worry...you'll still have your hair.

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.

Hair is an interesting biological structure. What we usually think of as 'hair' is really just the part we see... that's the hair shaft, which contains pigment (a chemical that gives color to things). There is also a hair follicle, which is a multi-cellular structure inside the skin of our scalp that creates the hair strand (making it grow), and also is responsible for the pigmentation. Some of the cells in the follicle make the chemical melanin, which is a skin and hair pigment in many species on our planet. \n\nHair turns grey when the pigment cells in the hair follicle stop making melanin. When this happens due to aging, it's mostly under the control of the genes we inherit. Long periods of constant stress may also contribute, but a big shock won't turn hair grey overnight.

The hair follicles on our head are different in structure from those that produce body hair. The length of body hair is determined by our genes (some folks are shaggier than others) but will never get as long as the hair grows on your head.\n\nWhen a hair follicle enters a new growth period, it starts to secrete the proteins that make up a hair shaft. The new hair grows out from the root plexus of the follicle until it pushes the old hair out, and then continues growing for a genetically determined amount of time. For body hair, it tends to grow for only 3-6 months and it grows at a slower rate. Then the follicle goes into a dormant stage again. Hair on the head grows at a fairly constant rate year round, and the hair shafts are generally thicker and stronger. Areas like the armpit, pubic area, and men's beards tend to be somewhere in between, as they do grow at a constant rate and can get fairly long if not trimmed.
