Description
Technical Field
The invention belongs to the technical field of hairdressing hot perm, and particularly relates to a perming auxiliary agent capable of improving perming effect or reducing hair damage and a hairdressing hot perm method using the perming auxiliary agent.
Background
The hair is mostly composed of insoluble keratin, and keratin accounts for more than 85%.Keratin is formed by mutually condensing amino acids into polypeptide chains, and then cross-linking the polypeptide chains through disulfide bonds (-S) -, which gives hair a firm structure. As early as the thirty years of the last century, it was discovered that these disulfide bonds can be interrupted by sulfide or sulfhydryl (-SH) -containing molecules in slightly alkaline solutions. This discovery provides a means for modern chemical perms, such as applying hair to a fabric containing thioglycolate ion (HSCH)2COO-) solution wets out, which, due to its reducing properties, breaks the disulfide groups in the hair into two thiol groups:
2HSCH2COO-(aq)+—S—S—(Hair)→(SCH2COO-)2(aq)+2HS-(Hair)
The hair which has lost the crosslinking action becomes very soft. The hair can then be curled up by a curling tool, and the polypeptide chains are displaced from one another induced by mechanical forces. At this time, the fixing liquid is added to fix the bent hair. The so-called "fixative" is in fact an oxidizing solution, which has the effect of making the hair form new disulfide bonds:
2HS-(Hair)+H2O2(aq)→—S—S—(Hair)+2H2O(l)
The hair polypeptide chains, again, recover their original toughness and form a permanent curly hair style, since many disulfide-based crosslinks are reformed. Typically, about 20% of the disulfide bonds in human hair are cleaved and about 90% of the broken disulfide bonds are reformed during styling.
It can be seen that permanent wave changes disulfide bonds, and the basic process of permanent wave is divided into two steps, the first step is to break the disulfide bonds in the hair by chemical reaction; the second step is the reconstitution and stabilization of the core structure.
The existing hair-care blanching techniques are roughly divided into two types, i.e., curling (e.g., digital waving) and straightening (e.g., ion waving). The working principle and method of the two types of blanching techniques are basically the same, and the method comprises the following steps:
the first step is as follows: the first agent for permanent wave, namely the softening agent, is coated on the hair, and the hair is softened after 1-20 minutes;
the softening agent comprises sulfur-containing compound (organic compound containing carbon-sulfur bond), such as ammonium thioglycolate and cysteine, as first agent for permanent wave, and can break disulfide bond in hair keratin after being applied on hair, thereby softening hair.
The second step is that: washing the first dose for perming, and wiping the hair dry;
the third step: heating hair-waving
When the hair is ironed and curled, the hair is firstly curled on a curling bar, the curling bar is heated by a blanching machine, or the hair is heated by a curling bar, the heating temperature is usually within the range of 60-140 ℃, the heating time is about 30 minutes, and the purpose is to ensure that keratin of the hair is physically deformed at high temperature to achieve the effect of curling hair;
when straightening hair, repeatedly straightening hair by using a hair-perming straightening plate clamp, wherein the temperature of the hair-perming straightening plate clamp is generally within the range of 140-230 ℃, and the aim of the hair-perming straightening plate clamp is to ensure that keratin of the hair is physically deformed under the action of high temperature so as to achieve the effect of straightening hair;
at this stage, the hair is in a dry state for most of the time during the heating process, since the high temperature enables the water to evaporate rapidly;
the fourth step: cooling the heated hair to room temperature, then using a second permanent-wave agent, namely a setting agent to be coated on the hair, and staying for about 10 minutes;
the setting agent contains strong oxidant, such as hydrogen peroxide, sodium bromate and the like, and the oxidation effect of the strong oxidant closes the broken disulfide bond to solidify the softened keratin so as to permanently set the deformed hair, thus finishing all the operations.
The fourth step may sometimes be omitted, but the permanent setting of the hair is achieved by closing the disulfide bonds by prolonged exposure to air, using the oxidative action of oxygen in the air.
The above-mentioned conventional blanching techniques have the disadvantages that,
when the first agent for hair perming is adopted to break the disulfide bonds of the hair, the hair is soft, meanwhile, the scales of the hair cuticles on the surface layer of the hair are damaged, the internal structure of the hair is in an unprotected state, so that water and nutrient contents in the hair are lost, keratin of the hair is denatured, and the hair is further induced to become yellow, crisp, glossy and elastic;
the first agent for permanent wave generally contains a large amount of sulfur-containing compounds, almost all practically available sulfur-containing compounds generate unpleasant and pungent odor, easily cause irritation reactions such as lacrimation, eye dryness and the like to a hairdresser who often contacts the first agent for permanent wave, even cause skin allergy, and can also cause phenomena of nail looseness and fingertip deformation if the first agent for permanent wave is often directly contacted by hands, thereby causing adverse effects on the health of the hairdresser;
the pH value of the first agent for permanent wave needs to be 8-10, but common sulfur-containing compounds such as ammonium thioglycolate and cysteine are acidic, and alkaline substances such as ammonia water and ethanolamine need to be added to improve the pH value, and the alkaline substances can damage hair.
In order to improve the damage of perm to hair, some heat perm methods use a care product in the stage from the first dose of perm to the heating stage, and play a care role on the hair: this is because the hair scale layer is in the maximum open state, and the hair can be supplemented with moisture and nutrition more effectively by using the care product, so that the damage of the first permanent wave agent to the hair/scalp during subsequent heating is reduced; however, these care products do not improve the effect of permanent waving.
In addition, most of the components of these products are volatilized at the high temperature of the second step, so that before entering the heating stage, these products need to be wiped dry to leave the hair in a semi-dry and semi-moist state, and then heated to prevent the liquid from boiling and scalding the scalp, and at the same time, the water vapor can break through the scales of the hair cuticles and damage the hair.
Because the prior hairdressing hot wave technology must use sulfur-containing compounds to break disulfide bonds, and in order to obtain good hair-waving effect, the first dosage for waving wave used generally contains a large amount of sulfur-containing compounds, so how to reduce the usage amount of sulfur-containing compounds on the basis of ensuring the hair-waving effect is always the pain point and difficulty of the hair-waving product.
Disclosure of Invention
The first object of the present invention is to provide a permanent wave aid which can improve the permanent wave effect or reduce hair damage, and which can reduce the damage to the hair by increasing the effect of ensuring the permanent wave or by reducing the amount of sulfur-containing compounds used while ensuring the effect of the permanent wave.
The second object of the present invention is to provide a method for hairdressing and permanent waving using the above-mentioned permanent waving aid, which can improve the permanent waving effect of the permanent waving by applying the permanent waving aid to hair in the third step and then performing the heating permanent waving, or reduce the amount of sulfur-containing compound used for the first permanent waving on the basis of securing the permanent waving effect, thereby reducing the damage to the hair.
The purpose of the invention is realized by the following technical scheme:
a hair waving auxiliary agent capable of improving hair waving effect or reducing hair damage contains water, and is characterized by further comprising at least one of a moisturizing agent and a moisturizing composition or a combination of the moisturizing agent and the moisturizing composition;
wherein:
the humectant is one or more of glycerol, propylene glycol, butanediol and panthenol;
the moisturizing composition is a combination of an oily component and a surfactant, wherein the oily component is one or two or more of vegetable oil, animal oil, mineral oil, chemical synthetic oil and silicone oil; the surfactant is one or two or more of an anionic surfactant, a cationic surfactant, a zwitterionic surfactant and a nonionic surfactant;
the humectant, the oily component and the surfactant have an evaporation pressure of less than 760mmHg at high temperature for heating and perming, and do not decompose;
when the perming aid comprises the moisturizing composition, the oil-water separation phenomenon does not occur at the high temperature of heating perming.
The present inventors have found that, in the course of the study of the prior art of permanent wave, the sulfur-containing compound in the first permanent wave dose needs to be in a state where the hair is wet to break the disulfide bonds of the hair, and that a small amount of the sulfur-containing compound remains in the hair after the second permanent wave step of permanent wave is performed to wash out the first permanent wave dose and dry the hair. However, in the prior art, in the third step of permanent waving, heating and waving, a small amount of water in the hair is rapidly evaporated to dry the hair, so that the chemical reaction (softening reaction) of the sulfur-containing compounds to break the disulfide bonds cannot be continued.
The following formula is a chemical reaction equation for sulfur-containing compounds to break the disulfide bonds of hair:
2HSCH2COO-(aq)+—S—S—(Hair)→(SCH2COO-)2(aq)+2HS-(Hair)
It can be seen from the reaction equation that the sulfur-containing compound must be in an ionic state in the liquid water when the reaction occurs, i.e., the hair is in a wet state, is a necessary condition for the chemical reaction to proceed.
Meanwhile, in the third step of heating and perming in the prior art, oxygen in the air can contact and rapidly enter the inside of the hair to neutralize the residual sulfur-containing compounds (redox reaction), so that the operation in the third step of perming is basically free from the chemical reaction of the sulfur-containing compounds to break the disulfide bonds of the hair, and only the hair is simply physically deformed under the condition of high temperature, and the perming effect depends on the operation of softening the hair in the first step, and the more sufficient the softening of the hair in the first step, the better the perming effect.
As a result of the continuous research by the present inventors, it has been found that the auxiliary for permanent wave can be applied to the hair before the third step of heating and permanent wave, so that the residual sulfur compounds in the hair can be used to break the disulfide bonds of the hair and the chemical activity can be improved, and thus, the residual sulfur compounds in the third step of permanent wave can be used to further break the disulfide bonds in the heating and permanent wave stage, so as to soften the hair keratin sufficiently, thereby improving the permanent effect of the hot wave.
The perming aid contains a large amount of humectant and/or moisturizing composition which is high temperature resistant and is not easy to volatilize, so the perming aid can exist stably at high temperature of heating perming, and is not volatilized and not decomposed. When the hair-waving adjuvant is coated on the surface of hair before heating and waving, and then heating and waving are carried out, it can keep the hair from drying due to high temperature, thereby achieving the following two purposes:
the hair-waving auxiliary agent can effectively prevent moisture in hair from evaporating and drying at high temperature, so that residual trace sulfur-containing compounds in the hair can further break disulfide bonds of the hair and soften keratin under the condition of moisture through high-temperature heating, thereby enabling the hair to be softened more fully;
meanwhile, the moisturizer or oily component which is not volatile at high temperature can effectively isolate the direct contact of air and hair, prevent oxygen in the air from entering the interior of the hair and neutralize residual sulfur-containing compounds, thereby enabling the softening reaction to be smoothly carried out and enhancing the hair perming effect.
The invention has no limit on the using amount of the perming auxiliary agent, and can achieve the purpose of improving the perming effect only by covering all the hair with the perming auxiliary agent. In other words, the use of the perming aid of the present invention provides a practicable basis for perming the first agent, the softening agent, to reduce sulfur-containing compounds while maintaining the original perming effect, thereby reducing the hair damage caused by perming.
