Sodium hydroxide is the active ingredient in what type of perm? What type of hair is easily penetrated by the waving lotion? Course hair with a strong resistant cuticle layer needs the additional swelling and penetration that come from what type of perm? Waving lotion breaks the desulfide bonds through this.

Perms also create greater control of hair that is coarse, wiry, and hard to manage. These sections are bent at an extremely sharp angle and will be stretched the most during relaxing.

The measurement of the thickness or thinness of a liquid that affects how the fluid flows. Coumpounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur. Perm activated by an outside heat source, usually a conventional hood-type hair dryer. Strong chemical side bonds formed when the sulfur atoms in two adjacent protein chains are joined together. Hair is wrapped at an angle of 90 degrees or perpendicular to its base section. One end paper is placed under and another is placed over the strand of hair being wrapped. One end paper is folded in half over the hair ends like an envelope. Hair strands are wrapped from the ends to the scalp in overlapping concentric layers. A matching sheet, or a matching quiz, is a sheet with two columns. In the first column there will be a word, statement or question, and in the second column are the answers, jumbled around in a different order.

Because acids neither swell the hair nor penetrate into the cortex, it is necessary for manufacturers to add an alkalizing agent to the solution. These relaxers straighten the hair completely, with less scalp irritation than other hydroxide relaxers. Your experience on this site will be improved by allowing cookies. Although they reduce scalp irritation, they do not reduce hair damage. The oxidation reaction caused by the neutralizer rebuilds the disulfide bonds that were broken by the thio relaxer. Hydrogen bonds attract oxygen. Some neutralizing shampoos intended for use after hydroxide relaxers have a built-in pH indicator that changes color to show when the pH of the hair has returned to normal. Perm softens hair to conform to new shape after wrapping. Game Preview. Cancel Download. Most guanidine hydroxide relaxers are recommended for sensitive scalps, and they are sold over-the-counter for home use. Thermal reconditioning is considered a specialty, and many manufacturers require certification in their particular procedure.

Just because a perm is indicated for use on color-treated hair does not mean it is safe for damaged or bleached hair. It stops the action of the waving solution and rebuilds the hair into its new curl form. Water molecule is formed. Do not chemically relax hair that has been treated with a metallic dye. The chemistry of hydroxide relaxers and permanent waving is different, but all relaxers and permanents change the shape of the hair by breaking disulfide bonds. Perm softens hair to conform to new shape after wrapping. Hydroxide relaxers go through a process called lanthionization, where they remove a sulfur atom from a disulfide bond and form a lanthionine bond. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out. How do hydroxide relaxers straighten the hair? The oxidation reaction caused by the neutralizer rebuilds the disulfide bonds that were broken by the thio relaxer.
