Rebonding, Straightening vs Smoothening: Difference and Comparison

Hair is an important part of the human body. Hair is found everywhere apart from the area where the skin is present. Hair grows out from the follicles found in the dermis.

Hair consists of an important protein called alpha keratin. Hair is of different colours due to the pigmentation of the skin. Majorly two types of hair colours are found, i.e., Black and Brown.

Hair has a variance of texture. It differs in volume, pattern, curls, consistency etc. Various types of techniques are used like hair rebonding, Hair Straightening and hair smoothening to make hair more attractive.

Key Takeaways

  1. Rebonding is a chemical process that alters the hair’s structure to make it permanently straight while straightening is a temporary method that uses heat to create a smooth, straight appearance.
  2. Smoothening is a milder, semi-permanent treatment that reduces frizz and makes hair more manageable without completely straightening.
  3. Rebonding requires professional expertise and can damage hair if not done correctly. While straightening and smoothening have fewer risks and can be done at home or in a salon.

Rebonding involves a multi-step procedure. Where the bond of the hair is broken using amino acids that exist in the follicle. After the bond is broken, it is refashioned into different shapes to give a new look.
