Although we all have different hair, the favorite hair is smooth. For more than 20 years there has been a technique to straighten hair semi-permanently, called Japanese straightening due to its country of origin. Today, Japanese straightening has opened up market all over the world and is one of the least invasive methods to achieve envy smoothing.
But what is Japanese straightening? It is a cocktail of products that are applied to the hair to change its internal structure, smoothing it semi-permanently. It is usually applied every 4-6 months, to treat the new wavy hair that grows little by little. It is ideal for those with curly or wavy hair, and it is recommended that those with frizzy hair try Brazilian keratin-based straightening first.
We have to differentiate that there are three types of chemical actives that are present in the hair straightening technique and that are: sodium hydroxide, ammonium thioglycolate (much softer than the one mentioned above) and ammonium disulfide. The process is similar for any of these three products.
Today we are going to show you the steps to perform a Japanese straightening.
First of all, the specialist hairdresser should check dry hair. This is to see if it is weak and if Japanese straightening is the best choice for hair. Once this has been done, the hair is moistened to re-examine it wet. The analysis of the client’s hair includes the elaboration of a history of the same. In this analysis you will pay special attention to the hardness of the hair, porosity, elasticity and resistance.
Once the analysis is done, the product is applied strand by strand from the root to the tip. It is allowed to act for 40 minutes. If the hair is poorly porous (as is the case with hair that has never been chemically treated) you should wait an additional approximate 30 min.
The hair is rinsed with plenty of water to remove all traces of the product. Excess moisture is removed with a towel and then a dryer is used to dry it completely.
You begin to straighten your hair, strand by strand, with an ionic iron. It is very important to choose thin strands and iron them from root to tip so that all the hair is perfectly smooth and shiny. If any strand were to be left out, it would remain with its original waves.
5 Fixing and drying
Once all the hair has been straightened, a neutralizing product, also called a fixative, is applied. After 20 minutes he washes his hair with shampoo and conditioner. Once it is finished you can dry your hair with a dryer. You’re ready to enjoy your new Japanese straightening!
