Perms

Perms often involve the use of chemicals that break and reform your hair to create a new shape of your hair. Your hair is washed and wrapped on a perm rod. This solution creates a chemical reaction that softens the inner structure of the hair by breaking some of the cross links within and between the protein chains of the hair. The hair swells, stretches and softens, then molds around the shape of the perm rod.

Curly vs. Straight Hair

The way your hair looks is mainly because of your parents. The big reason it looks the way it does is because of genes coming from your parents, passed down from their parents and so on. Besides genetics, curly hair has a lot to do with your follicle, especially the shape of it. A person with curly hair would have a long oval shaped follicle that basically has a "hook" at the end of it. The sharper the hook the more curly your hair will be. Obviously is you have straight hair you will not have a "hook" at the end of your hair.

Hair Follicles

Ever Wonder Why Your Hair Turns Grey?

As you get older, so does your hair. Getting gray, silver, or white hair is a natural part of growing older. The main reason for your hair changing color is beacuase each hair has a follice that contains pigments. The pigments in your hair contain melanin, which gives the shaft of your hair its color. As we get older the pigments in our hair gradually die and stop producing melanin, which causes your hair to lose color and turn gray or even white.

Where Hair is Found

The Hair is located in the hair follicles. The hair follicles are located in the dermis. Which goes through the epidermis. So, the hair is located in the dermis of the skin.

What your Hair is Made of

Your hair is made up of many different things. It is mainly composed of keratin, which is a protein that is also found in your nails. Most of the keratin in our hair is actually dead. It is all formed from dead cells which the body sheds as new cells push up from underneath. According to www.hairfinder.com, your hair is about 91% protein and is made up of long chains of amino acids. The amino acids are made up of carbon, oxygen, hydrogen, nitrogen, and sulfur.

How does Hair grow?

You could lose up to 50 to 100 hairs a day, some of us don't get them back though. Hair is made up of thousands of follicles all over your head and they are not all working at the same time. Actually about 80% of hair follicles are working at one time. The rest of your follicles are "asleep." When asleep follicles start working again they start to push out old hair while making a new one.

Functions of Hair

Hair is a very important part of the body, and it performs many different functions. The function it performs depends on the location of the hair. For example, head hair protects the scalp from the suns rays so it won't get burnt easily. Eyebrows and eyelashes keep dust particles or anything of that matter out of the eye. The hair in your nostrils or ear canal keeps out dust, debris, or even insects from entering the body. Human body hairs also act as a sensory receptor that allows us to feel and also act as a warming sense as well.

Affects of Chemotherapy on your Hair

Chemotherapy usually results in hair loss, also knows as alopecia. The reason for this is because hair follicles grow fast and chemotherapy damages fast growing cells. After your treatment is over your hair will grow back, but different people have different reactions to the therapy. Some people get lucky and don't lose their hair at all but even though they don't lose their hair completely, it still causes the hair to become very thin.

Sebum

Sebaceous glands secrete sebum. Also, these glands are found all over the body. The Latin word sebum means fat. Sebum acts like a barrier. Sebum coats the hair follicles then travels through the pores to eventually reach the skin. It prevents contaminants and viruses from penetrating the skin. Also, it keeps the skin very moist and hydrated so it does not dry out.
