Answer . No, not unless the person has allergies or Asthma (especially in children.) It's generally the cat dander from the skin of the cat that can cause problems.
Hair on or around the nipples grows for maximum warmth during chilly days. The male orangutan grows approximately 64 nipple hairs to sustain its core temperature just like humans do.
It can vary tremendously depending on race, and continent (Africans' average hair thickness is higher than Europeans', for example). It also depends if you talk about body hair or head hair. Hair from a human head is normally between .04 and .25 millimeters, averaging normally .1. Body hair depends …on gender and even within individuals of the same gender and race it can be very different from an individual to another. The Thickest Hair in the human body belongs to a man's moustache. Usually hair is not completely tubular. Moustache hair is like a strap. The thinner dimension is as thick as 0.2MM and the thicker dimension is as thick as 0.3 MM. These are usually the thickest hairs measured. Sometimes very short abnormally thick hair is where the root is damaged and needs to be removed. (MORE)

you trim the ends just a tiny little bit so there are no more split ends about once every month and keep the hair healthy. You could eat garlic that causes hair to grow too
Well humans have hair on there head to protect their scalp from being burned from the sun. We have eyebrows to protect ourselves from sweat getting into our eyes.
\nThere are thousands of hair on the average human head. everyday the average person loses about 40 hairs. Now if you did not have thousands of hair on your head that would seem like a lot but since there are so many, 40 is a very small number.

The speed in which human hair grows can vary, but it can be approximated:. In one month a hair follicle grows about - 0.125 decimeters or 1.25 centimeters or 12.5 millimeters or 12,500 micrometers. In the customary / imperial units it is 0.492126 inches.. In a day a hair follicle grows a…bout - 0.044 centimeters or 0.44 millimeters or 440 micrometers or 440,000 nanometers. In the customary / imperial units it is 0.044 inches. . In a minute a hair follicle grows about - 0.00069 centimeters or 0.0069 millimeters or 6.9 micrometers or 6,900 nanometers or 6,900,000 picometer In the customary / imperial units it is 0.00027 inches. .

Wash your hair with oilive oil or baby oil. Then, when the hair is saturated, try and slide the paint off your hairs with your fingernails. Then shampoo.. This might take you a few nights, but it's not bad on your hair and a ton safer than any other way I know -- and it beats shaving your head :}
A human root hair cell is there in order to keep the hair shaftconnected to the scalp. It also produces the oils necessary for thehair.

NO. Even if the cat had "human-like" hair it wouldn't be human hair because it grew from a cat.
hair is dead as soon as it leaves you skull so we cannot feel haircuts but yes it is healthy if your hair is damaged
Don't eat it. It would be bad if it was dirty, otherwise there isn't much harm that a few dog hairs can do you, apart from making your house look messy.

Its almost impossible to count all your hairs. If you do count your hair it will take a little over a year.
A horse!!! How mean!! BUT very pretty hope to see you wearing them!!!. Actually extensions can be from humans. They are even graded in accordance to where they come from for example western Caucasian is the best quality hair you can buy. It's the softest. People sell their hair and also some female… jails require them to shave their heads and then that hair is sold. not so glamorous (MORE)

A program called "Locks of Love" will take your hair and donate it to make wigs for cancer patients.
No the hair itself is actually dead cells, just like the finger and toe nails. The root of the hair is supplied with blood but not the hair. I disagree.. Your hair is alive, that is how it grows. Your hair breathes!!
We grow hair for to keep in heat and for hygeine reasons. For hygeine think of all the little hairs in your nose and ears. They stop particles of dirt entering our bodies. And hair under our arms and around our gentitals do the same. They collest sweat and dirt. The other hairs all over our bodies t…rap heat in the cold and when it is warm they let heat out. (MORE)
a lot On the average there are over one hundred thousand strands of hair on a young adult. Blondes average about 140,000 strands, brunettes average 108,000 and redheads average 90,000.

Hair grows quickest in young adult women aged between sixteen and twenty-four (who are often then at the height of their possible reproductive capacity) (i got this answer from yahoo answers) (MORE)
No. . Bones are calcium-based and are part of the skeletalsystem. . Hair is protein-based and are part of the integumentary system.Hair is made of a special type of protein known as keratin. It isthe same material that makes your finger and toe nails.
The dog hair is clearly thicker. It appears to have a diameter of ~30Âµm while the human hair is ~25Âµm thick. The segments of the dog hair appear to be smaller. They appear to be about 10Âµm while the human hair is ~15Âµm. Also the human hair appears to have more uniform segments than that …of the dog hair. The human hair has higher roughness of 2.398 Âµm, while the dog hair has a roughness of 618.3 nm. . Source: www.asylumresearch.com/ Human vs dog .ppt. (MORE)
i really don't know i have some micro braids and i have the human blend hair i need help with curling mine. Someone help please.
It is actually very helpful. For example, your eyebrows stop sweat from going into your eyes.
YES... . The Individual method involves taking small amounts (maybe 20-50 strands) of extension hair (natural or synthetic, but we'll get to that later) and applying to small sections of your own hair by either weaving in, heat fusing, gluing, clamping with metal rods or using waxes and polymers. …All of these methods (except for the clamping which is self explanatory) involve coating your own hair with a chemical or foreign substance. These extensions usually only last a few months before they have to be taken out and completely re-done. The main problem with this method is taking the Hair Extensions out without damaging your own hair. Many people who sell this method to clients will swear that there is no damage to your own hair, but one hair extension expert told me that "in 17 years of doing hair extensions we have yet to see a client who has previously had the individual method applied without damage to their own hair. Without spelling it out I will leave it to your imagination what might happen to your own hair if you melt some plastic onto it or glue or clamp something to it". (MORE)
If you get a normal red laser pointer, you can pretty easily measure it at home. The wavelength of a red laser pointer is typically around 670 nanometers, the one you select may state differently; make note of it. Take one of your hairs and suspend it in front of the laser somehow, but make sure… its exactly 1 meter from a flat surface. When you turn on the laser, you should see a dashed line pattern on the board. Measure the distance from the center bright spot to the farthest bright spot you can see and count how many this is. The thickness of your hair is (laser wavelength)*(distance to flat surface)/(distance to bright spot). Then multiply this number by the number of bright spots you counted. So, lets say i could count up to 4 bright spots before it got too dim; i measure the distance from the center to this one to be 5 cm; laser is 670nm and my flat surface is 1 meter away. My thickness is (670*10^-9)*(1)*4/ (.05) = 54*10^-6 meters = 54 micrometers (MORE)
Premium human hair is 100% human hair that contains some synthetic fibers to give it a natural look
The "hair" used for "barbie" and other dolls of similar kinds, i.e. Bratz, my little pony, other dolls with brush-able hair, knock off brands etc. is a synthetic fiber. Usually a low grade of toykankalon or kanekalon. The main difference between these two types of synthetic fiber is that one is heat… sensitive while one is heat resistant. Human hair is far too expensive for the global yearly mass production of dolls and toys. Human hair is also unhygienic and far too delicate for an application such as this. Some very exclusive dolls made before the mass production of dolls such as "barbie" had human hair, however those dolls were cherished art forms not extrusion plastic and intended for today's consumer "throw-away" culture.

Animal hair, also known as fur, and human hair are both essential to the host creatures' environmental comfort and temperature regulation. However, the composition and structure of the two hair types are distinctly different. . Growth . Human hair grows and sheds continuously. Its length and style… are maintained through regular haircuts. Most animal hair, in contrast, in self-limiting and sheds seasonally. Its length is regulated biologically, meaning that it grows to a specific length, determined genetically, and then ceases to grow. Indentification . According to Web MD, strands of human hair carry chemical information which is specific to an indivudual, and which can be used for indentification. Animal hair, however, is indistinct, meaning that hair from two different animals of the same breed have no distinct difference, and cannot be used to identify an individual. In either case, according to the FBI, genetic information can only be accessed if the hair follicle is still attached to the root of the hair. Layers . Human hairs are all the same type of strand. Many animals, however, have two distinct layers of fur made up of hairs with different properties. The top layer is long and coarse, and the undercoat is short and fine. This two-layer coat type helps animal coats repel water, and protects the skin from extreme temperatures. Specialization . Many animals have specialized hair types that serve specific biological functions. For example, whiskers are a specialized hair which are connected to the nervous system, and which receives sensory information. They affect an animal's balance, sense of direction and depth perception. Similarly, porcupines and hedgehogs have modified hair strands called quills or spines, which act as defense mechanisms. .

Does anyone remember a tv show where there was two presenters a girl with blonde hair and a fella but there was also i think two human sized robots?
Sounds something like the Amazing ( or Magical) world of Alakazam. the lead players were Magician Mark Wilson and his wife Nannie Darnell. Ms. Darnell usually wore what I later found out was a Black Empire Gown on stage. As the plots inevitably involved magic- a pair of robots might have been en sui…te- or in synch! (MORE)

Humans do not have hair on their tongues. Humans and other mammals only grow hair from skin (epidermis) - the tissue on your tongue is not skin. Humans have hair of varying types growing from all skin except the palms of the hand, soles of the feet, lips, and eyelids. Your tongue is covered in mucou…s membranes, not skin. The top is covered in projections from this membrane called papillae, which contain taste buds and serous glands (which secrete some of the fluid in saliva.) But no hair. (MORE)
(Yaki) is a hair texture that is designed to look and feel like African American Hair (Black Peoples) that has been through a processing to make their own hair straight. This processing is called Relaxing.
Yes. It is very unlikely if you wash your hair on a regular basis. There are cases of severely neglected children who have had spiders in their hair.
You shouldn't have to as you can get human hair wigs in anytexture, but you'd treat it as you're relaxing your hair hair.
The length of a strand of human hair can vary greatly depending on the person. However, the width of a human hair, in terms of how big it is, can measure anywhere from 40 microns to 120 microns. A micron is 1 millionth of a meter.
ants can normally live in almost anything... so yes maybe ants canlive in human hair.
