When you have unkempt curly hair, no style would go the way as you want it to have. So how do you get silky smooth straight hair?Do you think you need to wrestle with blow dryer to fulfill your wish? No, not at all.
Among many hair straightening techniques—Japanese hair straightening technique and Brazilian keratin technique—are the most popular methods.
Japanese hair straightening technique
Japanese hair straightening technique is also called as thermal reconditioning. It is not exactly but still a permanent hair straightening technique which gives you silky smooth straight hair. This process changes the internal structure of your hair and removes all curls to create a pin- straight strand. Once straightened, hair will not go back to its frizzy or curly form although any new hair growth will maintain the natural texture of your hair. It requires low maintenance. And this treatment only straightens your hair.
This treatment needs chemical that will relaxthe hair using a calcium based hydroxide solution. The solution is applied to the hair and left to sit. It is then rinsed out, blow dried and ironed in small sections with a flat iron. You cannot wash your hair for next 72 hours for better results. After it has been ironed completely straight, a neutralizer is applied on it to keep the molecular bonds in place. Since this method involves breaking down the chemical bonds of the hair, it can be very detrimental on the hair.
You need to have consultation with your hair stylist before being able to go through this treatment. Because chemicals are used, it may be damaging to the hair and damage could be irreversible. People who undergo Japanese hair straightening on a regular basis should be sure to take care of their hair afterwards and be sure it is protected from heat.
Brazilian Keratin treatment is temporary which lasts for three to six months depending on the product used. This method will not straighten your hair but only soften your curls. It eliminates frizz and make your hair healthier over time. It will not grow out like Japanese hair straightening but just completely wears off.
This method straightens hair by sealing a liquid keratin or a preservative solution into hair with a titanium iron. The hair must not be washed for at least 3 to 4 days. You need to wash your hair with sodium-free, sulfate free shampoo and conditioner. The hair can be blow dried or left to dry naturally. With keratin treatment, the protein keratin formula is infused with iron into freshly washed hair using intense heat thus only impacting outside layer of the hair.
But it also has its own controversy to fill in. Though this treatment requires active keratin application, a protein found in top layer of our skin and hair, some keratin treatments contains formaldehyde, or more correctly chemical called formalin gets released into the atmosphere. Formaldehyde is one of the carcinogens and has been linked to certain cancers like leukemia. This is safe when proper protection and ventilation are used.
Both treatments offer a number of benefits for curly and frazzled strands. But Japanese straightening treatments may cause some damage to the hair and scalp if not applied properly.
Brazilian treatments not only strengthen the hair but also recondition the strands so your hair becomes stronger and more resilient.
Keratin treatments are safe for all kinds of chemically treated hair. This means the treatment could be safely used for hair that has been previously permed, straightened, relaxed, bleached, colored or highlighted. Do avoid Brazilian keratin treatments if you are pregnant, have severely damaged hair from too much bleaching, bleached hair that is superfine, stick-straight hair or have slight waves.
