SECTION 1 The Structure of Hair Although each distinct chemical texture service may use different chemicals and have different objectives and procedures, they all involve chemical and physical changes within the structure of the hair. Therefore, we need to begin by reviewing the structure of the hair and how chemicals can change that structure. The Cuticle C.O.E. CONTINUING EDUCATION All Rights Reserved.

Page 4 of 257 Starting from the outside in, we first encounter the cuticle, which is the tough outer layer and protects the hair from damage. A strong, compact cuticle layer makes for resistant hair, meaning that the hair resists penetration and is difficult to service. Although the cuticle is not directly involved in chemical texture services, the chemicals must be able to penetrate through the cuticle in order to be effective. Chemical hair texturizers offer you the ability to changer the hair's natural curl pattern. These alkaline solutions soften and swell the hair, raising the cuticle and thereby permitting the solution to penetrate through the cuticle to its target within the cortex. Coarse, resistant hair with a strong, compact cuticle layer requires a texturizer, which is highly alkaline (high pH). A less alkaline (lower pH) solution is more suited to porous, damaged, or chemically treated hair. The Cortex The cortex is the middle layer of the hair, located directly beneath the cuticle layer. The polypeptide chains of the cortex are connected by end bonds and cross-linked by side bonds that form the fibers and structure of hair. These chemical bonds hold the hair in its natural wave pattern and are responsible for the incredible strength and elasticity of human hair. Breaking the side bonds of the cortex makes it possible to change the natural wave pattern of the hair. Peptide Bonds (End Bonds) The chemical bonds that join the amino acids are called peptide bonds, in turn, link together to form long chains of amino acids called polypeptide chains. Proteins are long, coiled, complex polypeptide chains make of many different amino acids linked together, end-to-end, like pop beads. It is important to note that peptide bonds should not be broken during any salon service. Breaking the hair's peptide bonds causes the polypeptide chains to come apart and dramatically weakens the hair. If used incorrectly, chemical hair texturizers can break peptide bonds and cause hair breakage. Chemical hair texturizers must be used carefully. Side Bonds The cortex is made of millions of polypeptide chains cross-linked by three types of side bonds, or cross bonds: disulfide bonds, salt bonds, and hydrogen bonds, Altering these three types of side bonds is what makes wet setting, thermal styling, permanent waving, soft curl permanents, and chemical hair relaxing possible. Disulfide Bonds Disulfide bonds are formed between two cysteine amino acids, located on neighboring polypeptide chains. A disulfide bond joins a cysteine sulfur atom on one polypeptide chain with a second cysteine sulfur atom on a neighboring polypeptide chain to form cystine, the oxidized form of cysteine. Disulfide bonds are weaker than peptide bonds, but are much All Rights Reserved. Materials may not be copied, edited, reproduced, distributed, imitated in any way without written permission from C.O.

Disulfide bonds are strong chemical side bonds that are not broken by heat or water. Although there are far fewer disulfide bonds that are not broken by heat or water. Although there are far fewer disulfide bonds than hydrogen or salt bonds, disulfide bonds are the strongest of the three side bonds and account for about one-third of the hair's overall strength. The chemical and physical changes in disulfide bonds make permanent waving, soft curl permanents (curl re-forming), and chemical hair relaxing possible. Salt Bonds (Side Bonds) Salt bonds are relatively weak physical side bonds that are the result of an attraction between opposite electrical charges. Salt bonds are easily broken by changes in pH, as in permanent waving, and re-form when the pH returns to normal.
