Examples hair, nails, skin, water and even oxygen.

There are 118 known elements. The elements above 92 are synthetic.
There are 5 elements that are especially important for salon professionals to know:
Carbon
Oxygen
Hydrogen
Nitrogen
Sulfur
Why are these elements important in cosmetology? Hair itself is composed of 2 solids (carbon and  sulfur) and three gases (hydrogen, nitrogen, and  oxygen).

When the protein chains are placed next to each other, they can be linked together by four side bonds. The four bonds holding the protein chains together behave differently and all serve a different purpose in building of the hair. The four Side bonds are: 
1. Hydrogen bond 
2. Salt bond 
3. Disulfide bond 
4. van der Waal's Forces 
When giving chemical services, you are affecting all these side bonds. In order to keep the hair healthy, it is important to know how the four side bonds work. ]]> 2017-05-02 13:45:12 UTC https://padlet.com/lizcherry112/cosmetologyandmatter/wish/169419320 lkh63756 https://padlet.com/lizcherry112/cosmetologyandmatter/wish/169419412 are the smallest complete unit of an elements.

These amino acids join together in chains to form protiens. There are 22 common amino acids and hair is made up of 19 of these 22 amino acids.

Hydrogen Bonds work on the principle the unlike charges attract. Hydrogen bonding takes place when the hydrogen atom in one molecule is attracted to an atom of another molecule that has many negative electrons. Hair has many hydrogen bonds, which are individually very weak & can easily be broken by heat or water. Although the attraction in Hydrogen Bonds are weak, there are so many of them in the protein of the hair that they tend to organize the protein chain and Give hair its shape. About 35% of the hair's strength is due to the millions of hydrogen bonds in its structure.]]> 2017-05-04 12:43:31 UTC https://padlet.com/lizcherry112/cosmetologyandmatter/wish/169912732 lkh63756 https://padlet.com/lizcherry112/cosmetologyandmatter/wish/169915220 Are two or more atoms joined together by a chemical bond.

Second type of bond between protein chains. 

a result of the attraction of unlike charges 

the negative charge in one amino acid grouping attracts the positive charge in another amino acid groupings. 

Account for another 35%  of the hair's resistance to change and, like hydrogen bonds, are not particularly strong.

A lot of chemical services, particularly perms, relaxers affect the disulfide bonds directly by either breaking or reforming disulfide bond or reforming tit in a new shape. this process is a chemical change and creates lasting results. 
The side bond van der Waal's forces is based on the theory that atomic groups prefer an environment similar to theirs. this type of bonding is not important for your work as a hair designer other than to know that it exists and plays a role in bonding protein chains. ]]> 2017-05-08 05:44:35 UTC https://padlet.com/lizcherry112/cosmetologyandmatter/wish/170427816 sik25f62 https://padlet.com/lizcherry112/cosmetologyandmatter/wish/170487630 Peptide bonds are the backbone of all protein molecules. Peptide bonds are formed when two amino acids attatch end-to-end. This means that ultimately, hair is the linking together of protien groups. Peptide bonds should not be disturbed because doing so would destroy the protien strucutres that have been created by peptide bonding. An example would be if you were to put heat ona sodium hydroxide relaxer, the hair would be destroyed.]]> 2017-05-08 12:33:07 UTC https://padlet.com/lizcherry112/cosmetologyandmatter/wish/170487630 sik25f62 https://padlet.com/lizcherry112/cosmetologyandmatter/wish/170489331 Hair is a form of protein called keratin, in fact, hair is 97% keratin protein and 3% trace minerals.
