Difference between straightening and smoothingPopular
What is hair straightening?
Without too much detail, I would say that the manipulation happens in two stages.
1- With a very alkaline product, we must first artificially break the original organization of the keratin molecules (the fiber of which our hair is made), to impose on the hair a new structure and make it completely malleable. This, until the hair no longer opposes resistance and get the desired stiffness.
