Some netizens said that the hair permed before the New Year was not too curly for a few days, and I didn't know if it was a potion? Or is the hairdresser's technique not good? Toiling for hours and spending hundreds of oceans, the result is speechless.
There are many reasons why the hair is not rolled a few days after the perm, there are hair problems, there are also reasons for improper selection of the curl bar, and the improper operation of the technical operation, and the relationship with the perm potion is not very large, but the main reason is in the following four points:
1, fine soft hair choose a thicker bar, hair can not support the curl, a few days after the iron will not be rolled;
2, the effect of the potion is not enough, the internal link can not be completely decomposed and reorganized, but also will lead to a few days after the scald will not be rolled;
3. Excessive softening, serious damage to the internal structure of the guide, enlargement of the curl shape after perming, weakened elasticity, and hair is not too curly;
4. When the temperature is too low or too high when heating, the persistence of the roll shape becomes shorter.
This is the main reason why the hair is not rolled a few days after the perm, of course, some details in the perm process are not done well, which will also affect the durability of the curl, and even lead to serious damage to the hair.
Expand your knowledge
In order to let everyone know more clearly the reasons why the hair is not rolled a few days after the perm, the following is an in-depth analysis of these contents from a professional point of view, and you will understand the reason after reading it.
Hair texture does not match the bar
Perm is a fairly complex chemical and physical action, not to say how big the roll of the bar can be how big the curl, because the size of the roll must match the toughness and elasticity of the hair, if it does not meet this relationship, it will lead to the scalding out of the curl enlargement, or wash a few times is not too rolled.
Especially fine and soft hair, its own elasticity is weak, the toughness is not enough, more suitable for some small curls. If the fine soft hair chooses a thicker bar curl, its own elasticity cannot support the curl shape of the large volume, either not enough roll, or not long enough.
The same is true for damaged hair, the internal structure becomes loose for various reasons, the link structure is broken, the protein is lost, and the thicker bar curl is selected, which will also lead to the permed curl not being rolled enough, and the holding time is also very short, especially after blowing dry hair, it will be close to the feeling of straight hair.
But it is not to say that the rough and hard hair must be permed out of a larger curl, mainly depending on the number of amino bonds and disulfide bonds of the hair itself, there are very few people who lack these two links inside the hair, no matter what type of roll bar is selected, there will be just finished ironing and rolling, and after a few days it will not be rolled.
The potion is not effective enough
Perm mainly relies on the effect of the potion, cutting the disulfide key in the hair, and then with the help of the thickness and shape of the bar, so that the hair is deformed, and then under this shape, oxidation is set, and the straight hair will be permed out of the curly effect.
If the effect of the potion is insufficient, such as incomplete softening, the time of setting is too short, etc., it will lead to insufficient disulfide bond cutting, incomplete oxidation and recombination, and the elasticity and curl of the coil will be affected. Although the lack of action is extremely harmful to the hair, it will lead to too large a roll shape and too short a holding time.
The first agent of perm potion is mainly to cut off the disulfide bond in the hair, if the effect is insufficient, the number of disulfide key cuts will become smaller, and the shape of the hair will not be completely changed, which will seriously affect the quality and durability of the curl after perm.
The role of the second agent of the perm potion is to recombine the hair that cuts off the disulfide key on the shape of the curl bar, so that the hair will form a curl consistent with the curl bar. If the effect is insufficient, the reorganization is not thorough enough, and it will also lead to volume enlargement, which will not be rolled after a few days.
The potion is overactive
The first agent of perm potion is strongly alkaline, the PH value is as high as 9.3 or more, and the perm must rely on experience and understanding of the performance of the potion to accurately control the degree of its effect in order to perm high-quality curls.
If the potion is overactive, it will lead to excessive swelling of the hair, loose internal structure, loss of links, serious damage to hair texture, etc., so that the curl of the iron is not natural, either not rolled, or wet hair has a roll, blow dry will not be rolled. These phenomena are caused by excessive action of the potion, and in severe cases, the hair will be burned.
The second agent of the perm potion is an oxidant, the main ingredient is hydrogen peroxide or sodium bromate, which causes the hair to dry, brittle, easy to break, lighter in color, and split the tail. These phenomena will also affect the quality and persistence of curl, and the hair will not be curly enough for a few days after perm.
The temperature control is not delicate enough
The relationship between cold scalding and temperature is not very large, and the few days after scalding are mainly due to the above reasons. If it is hot, the temperature control requirements are very high. Because hot perm is also known as thermoplastic perm, the perm process in addition to softening, but also need to be shaped by heating, if the temperature is too high or too low, will affect the quality of the perm, affect the durability.
The temperature is insufficient, the keratin inside the hair cannot be decomposed and moved, and the hydrogen bond cannot be shaped, so that the curl shape of the blanch is easy to enlarge, lack of elasticity, and it may not be too rolled after washing several times.
If the temperature is too high, the keratin inside the hair will be carbonized, which not only affects the shaping of hydrogen bonds, but also causes the hair to become stiff, the curl shape of the perm is unnatural, the wet hair is curly, and the blow dry becomes straight or frizzy. This is also the main reason why there is not enough rolls in the days after the perm.
The above content is analyzed from a professional point of view, in layman's terms: the hairdresser is not at home, the experience is not rich enough, the size of the bar is not selected according to the hair quality, the perm is insufficient or excessive, the temperature is too low or too high, there will be a reduction in the quality of the curl, the hair quality is seriously damaged, and the few days after the perm are not enough to roll.
