As us know, the hair is consisted of of protein chains hosted together by series of physical and chemical bondswhich give the hair the shape and strength. The binding we space most pertained to with in styling the hair space the next bonds. Next bonds are uncovered in two develops – physical side bonds and also chemical side bonds. Breaking and also reforming these side bonds permit us to rearrange the wave pattern of the hair. Physical side bonds deserve to be damaged using heat and also water and also reform as soon as the hair dries and/or cools.

However, this write-up is around perming and relaxing and the scientific processes that occur. When the hair is permed (and sometimes when straightened) the de defiders bonds (the chemical side bonds) the the hair are damaged through a chemical reaction called ‘reduction’. A reduction reaction involves either the remove of oxygen or the enhancement of hydrogen. In the case of irreversible waving, the palliation is due to the enhancement of hydrogen.The de defiders bonds sign up with one sulfur atom ~ above one polypeptide chain to an additional sulfur atom on various polypeptide chain. Perms usage reducing agents referred to as thiol compounds, which break the de defiders bonds by including a hydrogen atom to each of the sulfur atoms in the de defiders bonds. V the disulfide bonds broken, the polypeptide chains space able to slip right into their brand-new shape.The damaged disulfide bonds room reformed v the neutralization of the thio compound offered to break them. The most typical neutralizer is hydrogen peroxide and also the chemical procedure that clears the hydrogen atoms and also reforms the de defiders bonds is called “oxidation”. Oxidation can an outcome in the lightening that the hair shade – particularly if a strong thio compound was offered – and this is why the hair should be rinsed carefully and blotted extensively before using the neutralizer. The oxidation reaction combine the hydrogen and oxygen atom in the peroxide molecules through the hydrogen atoms supplied to rest the disulfide bonds to type two different molecules the water. (Peroxide H2O2 + Hydrogen + Hydrogen + H + H = Water H2O + H2O)The removal of the hydrogen atoms from the sulfur atoms pressures them to revolutionary their disulfide bonds in the new shape (around the perm rods). The procedure is the very same for relaxers and straighteners that use thio compounds, except that these space removing curl quite than producing it.Hydroxide relaxers break the de defiders bonds in the hair by removing one atom the sulfur from the de defiders bond and also thereby convert it into a lanthionine bond. This process is dubbed lanthionization. When a hydroxide relaxer division a de defiders bond the bond is permanently broken and also can never be reformed.Hydroxide relaxers leaving the hair exceptionally alkaline also after rinsing. To restore the pH balance the the hair one acid-balanced shampoo or normalizing odor neutralizes any type of remaining hydroxide ion to reduced the pH of the hair and scalp. Some neutralizing shampoos to plan for use after hydroxide relaxers have actually a integrated color-change indicator to display when the hair’s pH has actually returned to normal. The neutralization/normalizing process with hydroxide relaxers never uses any kind of oxidation, in fact, oxidizing agents have the right to seriously damage hydroxide tranquil hair.Stacy - Hair Stylist©cg-tower.comSee also:How perms workThe organic pH level for hairA overview to permanent waves
