The structure of hair is the first thing that cosmetologists have to deal with. The proteins are in hair and are fibrous proteins called keratin. Keratin proteins are made up of polypeptide chains. There are also many bonds that are composed in our hair, and they all deal with elements and proteins. The bonds are the hydrogen bond, the salt bond, the cystine bond and the sugar bond. The hydrogen bond allows the hair stretch elasticity and return to its original shape. This bond can be located between the coilds of the alpha helix. The salt bond also has to due with part of the structure of our hair. Electro transfer between the side chain of an amino acid and the side chain of and acidic position running even with the rotation of the helix of the hair is called a salt bond. Cross-links between cystine residues (amino acids) of the main polypeptide chains work to form the cystine or disulfide bond, also known as the sulfur or S bond. The last bo

There are many ingredients in hair color, and these chemicals that are used on peoples hair is all reactions and involves chemistry. The two main ingredients that are in hair color products are hydrogen peroxide and ammonia. The developer or oxidizing agent that helps initiate the color forming process (hydrogen peroxide) Comes in varying strengths and forms. This oxidizing agent can let the color last longer and the larger the column the more amount of sulfur will be lost from the hair. The hair can lose weight and harden if loss of sulfur occurs. To avoid sulfur loss, the oxidizing agent should be kept at a 30 percent volume or less. Ammonia is an alkaline that makes the hair lighter. This process occurs as the peroxide meets the permanent hair color. Ammonia splits the hair cuticle and allows the color to go to the cortex of the hair. The person who invented the hair color product was Eugene Schuller and this was based on a chemical called paraphenylenediamine. Hair dye is a very popular product today and has ingredients that have to due with chemicals and reactions.

In conclusion, cosmetology is related with chemistry in hair, skin products and the job it self.

The cosmetology career is obviously one that will not be easily achieved, nor will it be easily kept; one must work very hard. The professional must always remember that he/she is there for the hair. However, if the customer expresses concern about their hair and asks you questions, refer them to a doctor. Always use your best judgement in these situations. A cosmetologist, whether they are shaving heads or applying facial mask
