Key Differences

Hair smoothening is a chemical process designed to soften and smoothen hair texture, making hair look sleek and manageable without altering its natural structure significantly. Hair straightening, on the other hand, involves physically altering the hair's structure to achieve straight hair, often using heat or chemical treatments.
Smoothening treatments typically use a milder formula compared to straightening treatments, aiming to reduce frizz and add silkiness to the hair. Straightening treatments, such as rebonding, provide a more permanent solution to curly or wavy hair, offering a pin-straight look.
The effects of smoothening are often seen as more natural-looking, as they soften curls rather than completely eliminating them. Straightening, particularly chemical straightening, can dramatically change hair's texture and appearance, offering a sleek, straight style.
Smoothening treatments generally last for a few months and are less damaging to the hair compared to straightening treatments. Straightening treatments, especially when involving chemicals or excessive heat, can lead to more hair damage if not properly maintained.
Maintenance for smoothened hair usually involves using specific shampoos and conditioners to prolong the effect, whereas straightened hair may require more intensive care and frequent touch-ups, especially at the roots as hair grows.
