option 2- hair rebonding

How hair rebonding works to straighten your hair from your natural curl? What occurs to the structure of hair when rebonding treatment takes place? What happens to the keratin in the hair during rebonding? What is/are the chemical(s) involved to re-structure your hair, to make it straight? Is it harmful?

during rebonding, the chemical bonds of your hair are broken. then they are rearranged and bonded back again permanently. this makes the rebonded hair remain straight while the newly grown hair will be in its original state. during the process, your hair can burn if ithe temperature is more than 180degrees. you can also experience baldness after afew years of regular rebonding. this is because your hair becomes weak and can break easily.there will be also a bad smell coming out
from the keratin while the rebonding is in process
