Q&A: Every day, I receive a lot of private messages from my hairdressing peers asking questions about perms. Because there is so much content, many of which I have said many times before, in order to improve the quality of the answers, I have selected a few representative questions from them to answer your questions, and I hope you will continue to support them.
1. The scalded huddle roll is loose and lacks cohesion.
I think there are four reasons for the lack of cohesion, one is that the softening is not in place or too much, the second is that there is too little moisture or the hair is too dry when winding the bar, the third is the incorrect way of winding the bar, such as the hair piece is too wide, the hair tail is not gathered enough, etc., and the fourth is the heating method is incorrect, the temperature is not accurate, and the node control of water release is not in place.
The solution is that it is recommended to systematically learn the technique of hot perm and understand the principle of perm, and this problem can be easily solved.
2. After straightening, the ends of the hair are not smooth and warped.
After straightening, the whole is good, but the ends of the hair are not very straight and will be curled. I've talked about this a few times in the previous **. The main reasons are these: because the ends of the hair are damaged, they dare not soften when they are softened, but they are not in place, and when they are straightened, they are worried about the end of the hair being burned, but the temperature is not in place, resulting in insufficient shaping ability, which will cause this kind of situation.
Solution, the focus of softening the hair ends, not only to prevent excessive but also to soften sufficiently, when straightening, first leave the hair ends out without pulling, and after the overall straightening, in the hair ends, with a low temperature to pull it again.
3. Is it useful to flush before cold perm?
The cold stamping does not flush before setting, and does not affect the curl degree and elasticity. The main purpose of flushing is to reduce the double damage of the first and second doses to the hair, because the first dose is useless after the end of the first dose, and the hair after the perm is dry and frizzy after not flushing.
Understanding this principle, it is up to you to decide whether to flush or not.
4. The elasticity of the scalded roll is very good, and the customer will not roll it after washing it twice at home.
Just blanched a good roll, wash a few times and don't roll, the problem should be in the second agent. If it is a problem with agent No. 1, it can be seen after dismantling the bar. If you are cold permed, it should be that the moisture on your hair is not dried before applying the second dose, and too much water will dilute the concentration of the second dose, resulting in the insufficient effect of the second dose. If it is hot, it should be that the second agent is applied before the bar is cooled, or the second agent is too short, and it is also possible that the potion is invalid.
Solution, after rinsing in cold scalding, be sure to use a dry towel to absorb the water. Before hot scalding the No. 2 agent, the bar temperature must be lower than 40 degrees, and the cap of the No. 2 agent that has not been used up must be tightened to prevent the oxidation of the potion.
5. How to heat the paste cold scalding potion?
There are also several kinds of paste-like cold scalding potions, some are cysteine, some are cysteine and thioated compounds, different potions are targeted, and the time requirements for heating are also different.
Normal cysteine cold perm potion heats healthy hair for 20 25 minutes, 4 6 damaged hair for 15 20 minutes, and 7 or more damaged hair for 10 minutes.
The heating methods are: electric heating cap, flying saucer, baking machine, heating machine, etc. There is no specific temperature requirement, as long as the temperature on the bar reaches 40 degrees, the potion will be effective. If the temperature is too high, it will affect the texture and dry hair after perming.
