How do different hair texture services change Side bonds?
How do various hair texture services change the side bonds? By re-forming the bonds. croquignole wrap. wrapped from the ends to the scalp in a overlapping concentric layers.
How does chemical texture service affect structure of the hair?
Chemical texturizers raise the pH of the hair to an alkaline state in order to soften and swell the hair shaft. This action opens the cuticle layer and allows the solution to reach the cortex layer, where restructuring takes place.
How do wet sets change Side bonds?
The major difference between a wet set & a permanent wave is the type of side bonds that are broken. A wet set breaks hydrogen bonds, whereas a permanent wave breaks disulfide bonds, which are much stronger & more resistant. Removing curl, leaving the hair smooth & wave-free.
What are the 3 types of chemical texture services?
Chemical texture services are hair services that cause a chemical change that alters the natural wave pattern of the hair. They include the following: Permanent waving; adding wave or curl to the hair. Relaxing; removing curl, leaving the hair smooth and wave free.
What are the two steps of the permanent wave process?
The redox process occurs during permanent waving in two phases. The first phase is called the reduction and the second phase is oxidation. When the reduction reaction occurs the hair’s disulfide bond is broken allowing the polypeptide chains to take a new curled shape.
What are the steps to a permanent wave?

What are the chemical reactions that take place during permanent waving?
The chemical reaction involved is called oxidation. Permanent waving solution breaks disulfide bonds by adding hydrogen. Thio neutralization rebuilds bonds by removing the hydrogen that was added by the permanent waving solution.
Which type of relaxers are commonly called lye relaxers?
The main active ingredient in a Lye Relaxer is Sodium Hydroxide (NaOH). Sodium Hydroxide relaxers are very effective in breaking down the hair’s bonds (straightening the hair) quickly. Because it processes quickly it is also the most commonly used relaxers by professionals..

What is the physical action of a texture service?
Chemical texture services create permanent changes in hair structure and appearance. to 18.2. 1. Permanent waving: physical actions of shampooing, rinsing, and wrapping hair around rods; chemical actions of waving lotion (reduction) and neutralizer (oxidation).
