Why Do Chemical Processes Only Change The Sulfur Bond

Chemical processes only change the sulfur bond. A hair strand is a group of hairs that consist of 3 to 5 hair fibers. A normal head of hair has about 100 to 150 thousand hair fibers. Lighter color hair usually has more hair fibers than darker colored hair while red hair has the fewest. Paper is twice as thick as the width of a hair fiber. The living portion of hair sits below the surface of the scalp. Each hair fiber sits in a bulb that provides nourishment and natural emollient or oil. Healthy hair grows from 2 to 6 years than has a short resting period then starts again with a new hair fiber. Genetics basically determine the life cycle of hair. Hair that is shaped like a circle is straight. The curlier the hair shaft the more elliptical

When using a permanent hair color the pH range is very similar to relaxers and perms. Potential for damage occurs in all chemical processes when dry damaged hair is a result of inappropriately used or overused treatments. Your hair is not alive so changing the shape is truly not a major consequence to the hair shaft itself. The main problem begins when hair is inappropriately processed. Bonds are being made and broken every time water is applied to hair. Think of how humidity affects your hair. Hydrogen bonds are being made causing the hair to fall flat or puff up depending on the hair type. Hair with the curliest hair type has fewer cuticle layers than straighter hair which straight hair can have up to 10 cuticle layers. The cuticle layer protects the hair from the external environment and consists of 45% cystine. Less cuticle layers explain why curling or applying heat to chemically treated hair makes it more fragile and easier to break. With chemicals, including water as a chemical, the layers swells allowing the hair to change shape by a chemical
